+/******************************************************************************************* +* +* raygui v4.0 - A simple and easy-to-use immediate-mode gui library +* +* DESCRIPTION: +* raygui is a tools-dev-focused immediate-mode-gui library based on raylib but also +* available as a standalone library, as long as input and drawing functions are provided. +* +* FEATURES: +* - Immediate-mode gui, minimal retained data +* - +25 controls provided (basic and advanced) +* - Styling system for colors, font and metrics +* - Icons supported, embedded as a 1-bit icons pack +* - Standalone mode option (custom input/graphics backend) +* - Multiple support tools provided for raygui development +* +* POSSIBLE IMPROVEMENTS: +* - Better standalone mode API for easy plug of custom backends +* - Externalize required inputs, allow user easier customization +* +* LIMITATIONS: +* - No editable multi-line word-wraped text box supported +* - No auto-layout mechanism, up to the user to define controls position and size +* - Standalone mode requires library modification and some user work to plug another backend +* +* NOTES: +* - WARNING: GuiLoadStyle() and GuiLoadStyle{Custom}() functions, allocate memory for +* font atlas recs and glyphs, freeing that memory is (usually) up to the user, +* no unload function is explicitly provided... but note that GuiLoadStyleDefaulf() unloads +* by default any previously loaded font (texture, recs, glyphs). +* - Global UI alpha (guiAlpha) is applied inside GuiDrawRectangle() and GuiDrawText() functions +* +* CONTROLS PROVIDED: +* # Container/separators Controls +* - WindowBox --> StatusBar, Panel +* - GroupBox --> Line +* - Line +* - Panel --> StatusBar +* - ScrollPanel --> StatusBar +* - TabBar --> Button +* +* # Basic Controls +* - Label +* - LabelButton --> Label +* - Button +* - Toggle +* - ToggleGroup --> Toggle +* - ToggleSlider +* - CheckBox +* - ComboBox +* - DropdownBox +* - TextBox +* - ValueBox --> TextBox +* - Spinner --> Button, ValueBox +* - Slider +* - SliderBar --> Slider +* - ProgressBar +* - StatusBar +* - DummyRec +* - Grid +* +* # Advance Controls +* - ListView +* - ColorPicker --> ColorPanel, ColorBarHue +* - MessageBox --> Window, Label, Button +* - TextInputBox --> Window, Label, TextBox, Button +* +* It also provides a set of functions for styling the controls based on its properties (size, color). +* +* +* RAYGUI STYLE (guiStyle): +* raygui uses a global data array for all gui style properties (allocated on data segment by default), +* when a new style is loaded, it is loaded over the global style... but a default gui style could always be +* recovered with GuiLoadStyleDefault() function, that overwrites the current style to the default one +* +* The global style array size is fixed and depends on the number of controls and properties: +* +* static unsigned int guiStyle[RAYGUI_MAX_CONTROLS*(RAYGUI_MAX_PROPS_BASE + RAYGUI_MAX_PROPS_EXTENDED)]; +* +* guiStyle size is by default: 16*(16 + 8) = 384*4 = 1536 bytes = 1.5 KB +* +* Note that the first set of BASE properties (by default guiStyle[0..15]) belong to the generic style +* used for all controls, when any of those base values is set, it is automatically populated to all +* controls, so, specific control values overwriting generic style should be set after base values. +* +* After the first BASE set we have the EXTENDED properties (by default guiStyle[16..23]), those +* properties are actually common to all controls and can not be overwritten individually (like BASE ones) +* Some of those properties are: TEXT_SIZE, TEXT_SPACING, LINE_COLOR, BACKGROUND_COLOR +* +* Custom control properties can be defined using the EXTENDED properties for each independent control. +* +* TOOL: rGuiStyler is a visual tool to customize raygui style: github.com/raysan5/rguistyler +* +* +* RAYGUI ICONS (guiIcons): +* raygui could use a global array containing icons data (allocated on data segment by default), +* a custom icons set could be loaded over this array using GuiLoadIcons(), but loaded icons set +* must be same RAYGUI_ICON_SIZE and no more than RAYGUI_ICON_MAX_ICONS will be loaded +* +* Every icon is codified in binary form, using 1 bit per pixel, so, every 16x16 icon +* requires 8 integers (16*16/32) to be stored in memory. +* +* When the icon is draw, actually one quad per pixel is drawn if the bit for that pixel is set. +* +* The global icons array size is fixed and depends on the number of icons and size: +* +* static unsigned int guiIcons[RAYGUI_ICON_MAX_ICONS*RAYGUI_ICON_DATA_ELEMENTS]; +* +* guiIcons size is by default: 256*(16*16/32) = 2048*4 = 8192 bytes = 8 KB +* +* TOOL: rGuiIcons is a visual tool to customize/create raygui icons: github.com/raysan5/rguiicons +* +* RAYGUI LAYOUT: +* raygui currently does not provide an auto-layout mechanism like other libraries, +* layouts must be defined manually on controls drawing, providing the right bounds Rectangle for it. +* +* TOOL: rGuiLayout is a visual tool to create raygui layouts: github.com/raysan5/rguilayout +* +* CONFIGURATION: +* #define RAYGUI_IMPLEMENTATION +* Generates the implementation of the library into the included file. +* If not defined, the library is in header only mode and can be included in other headers +* or source files without problems. But only ONE file should hold the implementation. +* +* #define RAYGUI_STANDALONE +* Avoid raylib.h header inclusion in this file. Data types defined on raylib are defined +* internally in the library and input management and drawing functions must be provided by +* the user (check library implementation for further details). +* +* #define RAYGUI_NO_ICONS +* Avoid including embedded ricons data (256 icons, 16x16 pixels, 1-bit per pixel, 2KB) +* +* #define RAYGUI_CUSTOM_ICONS +* Includes custom ricons.h header defining a set of custom icons, +* this file can be generated using rGuiIcons tool +* +* #define RAYGUI_DEBUG_RECS_BOUNDS +* Draw control bounds rectangles for debug +* +* #define RAYGUI_DEBUG_TEXT_BOUNDS +* Draw text bounds rectangles for debug +* +* VERSIONS HISTORY: +* 4.0 (12-Sep-2023) ADDED: GuiToggleSlider() +* ADDED: GuiColorPickerHSV() and GuiColorPanelHSV() +* ADDED: Multiple new icons, mostly

The topology core - * currently recognises the following object types :- - * - * * Controls (mixer, enumerated and byte) including TLV data. - * * PCMs (Front End DAI & DAI link) - * * DAPM widgets - * * DAPM graph elements. - * * Physical DAI & DAI links - * * Private data for each object type. - * * Manifest (containing count of each object type) - * - *

Topology File Format

- * - * The topology text format uses the standard ALSA configuration file format to - * describe each topology object type. This allows topology objects to include - * other topology objects as part of their definition. i.e. a TLV data object - * can be shared amongst many control objects that use the same TLV data. - * - * - *

Controls

- * Topology audio controls can belong to three different types :- - * * Mixer control - * * Enumerated control - * * Byte control - * - * Each control type can contain TLV data, private data, operations and also - * belong to widget objects.
- * - *
Control Operations
- * Driver Kcontrol callback info(), get() and put() operations are mapped with - * the CTL ops section in topology configuration files. The ctl ops section can - * assign operations using the standard names (listed below) for the standard - * kcontrol types or use ID numbers (>256) to map to bespoke driver controls.
- * - * 
- *
- *	ops."ctl" {
- *		info "volsw"
- *		get "257"
- *		put "257"
- *	}
- *
- *
- * - * This mapping shows info() using the standard "volsw" info callback whilst - * the get() and put() are mapped to bespoke driver callbacks.
- * - * The Standard operations names for control get(), put() and info calls - * are :- - * * volsw - * * volsw_sx - * * volsw_xr_sx - * * enum - * * bytes - * * enum_value - * * range - * * strobe - * -*
Control Access
- * Controls access can be specified using the "access" section. If no "access" - * section is defined then default RW access flags are set for normal and TLV - * controls. - * - * 
- *	access [
- *		read
- *		write
- *		tlv_command
- *	]
- *
- * - * The standard access flags are as follows :- - * * read - * * write - * * read_write - * * volatile - * * timestamp - * * tlv_read - * * tlv_write - * * tlv_read_write - * * tlv_command - * * inactive - * * lock - * * owner - * * tlv_callback - * * user - * - *
Control TLV Data
- * Controls can also use TLV data to represent dB information. This can be done - * by defining a TLV section and using the TLV section within the control. - * The TLV data for DBScale types are defined as follows :- - * - * 
- *	scale {
- *		min "-9000"
- *		step "300"
- *		mute "1"
- *	}
- *
- * - * Where the meanings and values for min, step and mute are exactly the same - * as defined in driver code. - * - *
Control Channel Mapping
- * Controls can also specify which channels they are mapped with. This is useful - * for userspace as it allows applications to determine the correct control - * channel for Left and Right etc. Channel maps are defined as follows :- - * - * 
- *	channel."name" {
- *		reg "0"
- *		shift "0"
- *	}
- *
- * - * The channel map reg is the register offset for the control, shift is the - * bit shift within the register for the channel and the section name is the - * channel name and can be one of the following :- - * - * 
- *  * mono		# mono stream
- *  * fl 		# front left
- *  * fr		# front right
- *  * rl		# rear left
- *  * rr		# rear right
- *  * fc		# front center
- *  * lfe		# LFE
- *  * sl		# side left
- *  * sr		# side right
- *  * rc		# rear center
- *  * flc		# front left center
- *  * frc		# front right center
- *  * rlc		# rear left center
- *  * rrc		# rear right center
- *  * flw		# front left wide
- *  * frw		# front right wide
- *  * flh		# front left high
- *  * fch		# front center high
- *  * frh		# front right high
- *  * tc		# top center
- *  * tfl		# top front left
- *  * tfr		# top front right
- *  * tfc		# top front center
- *  * trl		# top rear left
- *  * trr		# top rear right
- *  * trc		# top rear center
- *  * tflc		# top front left center
- *  * tfrc		# top front right center
- *  * tsl		# top side left
- *  * tsr		# top side right
- *  * llfe		# left LFE
- *  * rlfe		# right LFE
- *  * bc		# bottom center
- *  * blc		# bottom left center
- *  * brc		# bottom right center
- *
- * - *
Control Private Data
- * Controls can also have private data. This can be done by defining a private - * data section and including the section within the control. The private data - * section is defined as follows :- - * - * 
- * SectionData."pdata for EQU1" {
- *	file "/path/to/file"
- *	bytes "0x12,0x34,0x56,0x78"
- *	shorts "0x1122,0x3344,0x5566,0x7788"
- *	words "0xaabbccdd,0x11223344,0x66aa77bb,0xefef1234"
- *	tuples "section id of the vendor tuples"
- * };
- *
- * The file, bytes, shorts, words and tuples keywords are all mutually - * exclusive as the private data should only be taken from one source. - * The private data can either be read from a separate file or defined in - * the topology file using the bytes, shorts, words or tuples keywords. - * The keyword tuples is to define vendor specific tuples. Please refer to - * section Vendor Tokens and Vendor tuples. - * - * It's easy to use a vendor tuples object to define a C structure instance. - * And a data section can include multiple vendor tuples objects: - * - * 
- * SectionData."data element name" {
- *	index "1"	#Index number
- *	tuples [
- *		"id of the 1st vendor tuples section"
- *		"id of the 2nd vendor tuples section"
- *		...
- *	]
- * };
- *
- * - *
How to define an element with private data
- * An element can refer to a single data section or multiple data - * sections. - * - *
To refer to a single data section:
- * 
- * Sectionxxx."element name" {
- *    ...
- *	data "name of data section"		# optional private data
- * }
- *
- * - *
To refer to multiple data sections:
- * 
- * Sectionxxx."element name" {
- *	...
- *	data [						# optional private data
- *		"name of 1st data section"
- *		"name of 2nd data section"
- *		...
- *	]
- * }
- *
- * And data of these sections will be merged in the same order as they are - * in the list, as the element's private data for kernel. - * - * - * - *
Vendor Tokens
- * A vendor token list is defined as a new section. Each token element is - * a pair of string ID and integer value. And both the ID and value are - * vendor-specific. - * - * 
- * SectionVendorTokens."id of the vendor tokens" {
- *	comment "optional comments"
- *	VENDOR_TOKEN_ID1 "1"
- *	VENDOR_TOKEN_ID2 "2"
- *	VENDOR_TOKEN_ID3 "3"
- *	...
- * }
- *
- * - *
Vendor Tuples
- * Vendor tuples are defined as a new section. It contains a reference to - * a vendor token list and several tuple arrays. - * All arrays share a vendor token list, defined by the tokens keyword. - * Each tuple array is for a specific type, defined by the string following - * the tuples keyword. Supported types are: string, uuid, bool, byte, - * short and word. - * - * 
- * SectionVendorTuples."id of the vendor tuples" {
- *	tokens "id of the vendor tokens"
- *
- *	tuples."string" {
- *		VENDOR_TOKEN_ID1 "character string"
- *		...
- *	}
- *
- *	tuples."uuid" {			# 16 characters separated by commas
- *		VENDOR_TOKEN_ID2 "0x01,0x02,...,0x0f"
- *		...
- *	}
- *
- *	tuples."bool" {
- *		VENDOR_TOKEN_ID3 "true/false"
- *		...
- *	}
- *
- *	tuples."byte" {
- *		VENDOR_TOKEN_ID4 "0x11"
- *		VENDOR_TOKEN_ID5 "0x22"
- *		...
- *	}
- *
- *	tuples."short" {
- *		VENDOR_TOKEN_ID6 "0x1122"
- *		VENDOR_TOKEN_ID7 "0x3344"
- *		...
- *	}
- *
- *	tuples."word" {
- *		VENDOR_TOKEN_ID8 "0x11223344"
- *		VENDOR_TOKEN_ID9 "0x55667788"
- *		...
- *	}
- * }
- *
- * To define multiple vendor tuples of same type, please append some - * characters after the type string ("string", "uuid", "bool", "byte", "short" - * or "word"), to avoid ID duplication in the SectionVendorTuples.
- * The parser will check the first few characters in ID to get the tuple type. - * Here is an example: - * 
- * SectionVendorTuples."id of the vendor tuples" {
- *    ...
- *	tuples."word.module0" {
- *		VENDOR_TOKEN_PARAM_ID1 "0x00112233"
- *		VENDOR_TOKEN_PARAM_ID2 "0x44556677"
- *		...
- *	}
- *
- *	tuples."word.module2" {
- *		VENDOR_TOKEN_PARAM_ID1 "0x11223344"
- *		VENDOR_TOKEN_PARAM_ID2 "0x55667788"
- *		...
- *	}
- *	...
- * }
- *
- *
- * - *
Mixer Controls
- * A mixer control is defined as a new section that can include channel mapping, - * TLV data, callback operations and private data. The mixer section also - * includes a few other config options that are shown here :- - * - * 
- * SectionControlMixer."mixer name" {
- *	comment "optional comments"
- *
- *	index "1"			# Index number
- *
- *	channel."name" {		# Channel maps
- *	   ....
- *	}
- *
- *	ops."ctl" {			# Ops callback functions
- *	   ....
- *	}
- *
- *	max "32"			# Max control value
- *	invert "0"			# Whether control values are inverted
- *
- *	tlv "tld_data"			# optional TLV data
- *
- *	data "pdata for mixer1"		# optional private data
- * }
- *
- * - * The section name is used to define the mixer name. The index number can be - * used to identify topology objects groups(index "0" is common, fit for all - * user cases).This allows driver operations on objects with index number N and - * can be used to add/remove pipelines of objects whilst other objects are - * unaffected. - * - *
Byte Controls
- * A byte control is defined as a new section that can include channel mapping, - * TLV data, callback operations and private data. The bytes section also - * includes a few other config options that are shown here :- - * - * 
- * SectionControlBytes."name" {
- *	comment "optional comments"
- *
- *	index "1"			# Index number
- *
- *	channel."name" {		# Channel maps
- *	   ....
- *	}
- *
- *	ops."ctl" {			# Ops callback functions
- *	   ....
- *	}
- *
- *	base "0"			# Register base
- *	num_regs "16"			# Number of registers
- *	mask "0xff"			# Mask
- *	max "255"			# Maximum value
- *
- *	tlv "tld_data"			# optional TLV data
- *
- *	data "pdata for mixer1"		# optional private data
- * }
- *
- * - *
Enumerated Controls
- * A enumerated control is defined as a new section (like mixer and byte) that - * can include channel mapping, callback operations, private data and - * text strings to represent the enumerated control options.
- * - * The text strings for the enumerated controls are defined in a separate - * section as follows :- - * - * 
- * SectionText."name" {
- *
- *		Values [
- *			"value1"
- *			"value2"
-			"value3"
- *		]
- * }
- *
- * - * All the enumerated text values are listed in the values list.
- * The enumerated control is similar to the other controls and defined as - * follows :- - * - * 
- * SectionControlMixer."name" {
- *	comment "optional comments"
- *
- *	index "1"			# Index number
- *
- *	texts "EQU1"			# Enumerated text items
- *
- *	channel."name" {		# Channel maps
- *	   ....
- *	}
- *
- *	ops."ctl" {			# Ops callback functions
- *	   ....
- *	}
- *
- *	data "pdata for mixer1"		# optional private data
- * }
- *
- * - *

DAPM Graph

- * DAPM graphs can easily be defined using the topology file. The format is - * very similar to the DAPM graph kernel format. :- - * - * 
- * SectionGraph."dsp" {
- *	index "1"			# Index number
- *
- *	lines [
- *		"sink1, control, source1"
- *		"sink2, , source2"
- *	]
- * }
- *
- * - * The lines in the graph are defined as a variable size list of sinks, - * controls and sources. The control name is optional as some graph lines have - * no associated controls. The section name can be used to differentiate the - * graph with other graphs, it's not used by the kernel atm. - * - *

DAPM Widgets

- * DAPM widgets are similar to controls in that they can include many other - * objects. Widgets can contain private data, mixer controls and enum controls. - * - * The following widget types are supported and match the driver types :- - * - * * input - * * output - * * mux - * * mixer - * * pga - * * out_drv - * * adc - * * dac - * * switch - * * pre - * * post - * * aif_in - * * aif_out - * * dai_in - * * dai_out - * * dai_link - * - * Widgets are defined as follows :- - * - * 
- * SectionWidget."name" {
- *
- *	index "1"			# Index number
- *
- *	type "aif_in"			# Widget type - detailed above
- *	stream_name "name"		# Stream name
- *
- *	no_pm "true"			# No PM control bit.
- *	reg "20"			# PM bit register offset
- *	shift "0"			# PM bit register shift
- *	invert "1			# PM bit is inverted
- *	subseq "8"			# subsequence number
- *
- *	event_type "1"			# DAPM widget event type
- *	event_flags "1"			# DAPM widget event flags
- *
- *	mixer "name"			# Optional Mixer Control
- *	enum "name"			# Optional Enum Control
- *
- *	data "name"			# optional private data
- * }
- *
- * - * The section name is the widget name. The mixer and enum fields are mutually - * exclusive and used to include controls into the widget. The index and data - * fields are the same for widgets as they are for controls whilst the other - * fields map on very closely to the driver widget fields. - * - *
Widget Private Data
- * Widget can have private data. For the format of the private data, please - * refer to section Control Private Data. - * - *

PCM Capabilities

- * Topology can also define the PCM capabilities of front end or physical DAIs. - * Capabilities can be defined with the following section :- - * - * 
- * SectionPCMCapabilities."name" {
- *
- *	formats "S24_LE,S16_LE"		# Supported formats
- *	rates "48000"			# Supported rates
- *	rate_min "48000"		# Max supported sample rate
- *	rate_max "48000"		# Min supported sample rate
- *	channels_min "2"		# Min number of channels
- *	channels_max "2"		# max number of channels
- * }
- *
- * The supported formats use the same naming convention as the driver macros. - * The PCM capabilities name can be referred to and included by PCM and - * physical DAI sections. - * - *

PCM Configurations

- * PCM runtime configurations can be defined for playback and capture stream - * directions with the following section :- - * - * 
- * SectionPCMConfig."name" {
- *
- *	config."playback" {		# playback config
- *		format "S16_LE"		# playback format
- *		rate "48000"		# playback sample rate
- *		channels "2"		# playback channels
- *		tdm_slot "0xf"		# playback TDM slot
- *	}
- *
- *	config."capture" {		# capture config
- *		format "S16_LE"		# capture format
- *		rate "48000"		# capture sample rate
- *		channels "2"		# capture channels
- *		tdm_slot "0xf"		# capture TDM slot
- *	}
- * }
- *
- * - * The supported formats use the same naming convention as the driver macros. - * The PCM configuration name can be referred to and included by PCM and - * physical link sections. - * - *

PCM (Front-end DAI & DAI link)

- * PCM sections define the supported capabilities and configurations for - * supported playback and capture streams, names and flags for front end - * DAI & DAI links. Topology kernel driver will use a PCM object to create - * a pair of FE DAI & DAI links. - * - * 
- * SectionPCM."name" {
- *
- *	index "1"			# Index number
- *
- *	id "0"				# used for binding to the PCM
- *
- *	dai."name of front-end DAI" {
- *		id "0"		# used for binding to the front-end DAI
- *	}
- *
- *	pcm."playback" {
- *		capabilities "capabilities1"	# capabilities for playback
- *
- *		configs [		# supported configs for playback
- *			"config1"
- *			"config2"
- *		]
- *	}
- *
- *	pcm."capture" {
- *		capabilities "capabilities2"	# capabilities for capture
- *
- *		configs [		# supported configs for capture
- *			"config1"
- *			"config2"
- *			"config3"
- *		]
- *	}
- *
- *	# Optional boolean flags
- *	symmetric_rates			"true"
- *	symmetric_channels		"true"
- *	symmetric_sample_bits		"false"
- *
- *	data "name"			# optional private data
- * }
- *
- * - *

Physical DAI Link Configurations

- * The runtime configurations of a physical DAI link can be defined by - * SectionLink.
Backend DAI links belong to physical links, and can - * be configured by either SectionLink or SectionBE, with same syntax. - * But SectionBE is deprecated atm since the internal processing is - * actually same. - * - * 
- * SectionLink."name" {
- *
- *	index "1"			# Index number
- *
- *	id "0"				# used for binding to the link
- *
- *	stream_name "name"		# used for binding to the link
- *
- *	hw_configs [	# runtime supported HW configurations, optional
- *		"config1"
- *		"config2"
- *		...
- *	]
- *
- *	default_hw_conf_id "1"		#default HW config ID for init
- *
- *	# Optional boolean flags
- *	symmetric_rates			"true"
- *	symmetric_channels		"false"
- *	symmetric_sample_bits		"true"
- *
- *	data "name"			# optional private data
- * }
- *
- * - * A physical link can refer to multiple runtime supported hardware - * configurations, which is defined by SectionHWConfig. - * - * 
- * SectionHWConfig."name" {
- *
- *	id "1"				# used for binding to the config
- *	format "I2S"			# physical audio format.
- *	bclk   "master"			# Platform is master of bit clock
- *	fsync  "slave"			# Platform is slave of fsync
- * }
- *
- * - *

Physical DAI

- * A physical DAI (e.g. backend DAI for DPCM) is defined as a new section - * that can include a unique ID, playback and capture stream capabilities, - * optional flags, and private data.
- * Its PCM stream capablities are same as those for PCM objects, - * please refer to section 'PCM Capabilities'. - * - * 
- * SectionDAI."name" {
- *
- *	index "1"			# Index number
- *
- *	id "0"				# used for binding to the Backend DAI
- *
- *	pcm."playback" {
- *		capabilities "capabilities1"	# capabilities for playback
- *	}
- *
- *	pcm."capture" {
- *		capabilities "capabilities2"	# capabilities for capture
- *	}
- *
- *	symmetric_rates "true"			# optional flags
- *	symmetric_channels "true"
- *	symmetric_sample_bits "false"
- *
- *	data "name"			# optional private data
- * }
- *
- * - *

Manifest Private Data

- * Manfiest may have private data. Users need to define a manifest section - * and add the references to 1 or multiple data sections. Please refer to - * section 'How to define an element with private data'.
- * And the text conf file can have at most 1 manifest section.

- * - * Manifest section is defined as follows :- - * - * 
- * SectionManifest"name" {
- *
- *	data "name"			# optional private data
- * }
- *
- * - *

Include other files

- * Users may include other files in a text conf file via alsaconf syntax - * . This allows users to define common info - * in separate files (e.g. vendor tokens, tuples) and share them for - * different platforms, thus save the total size of config files.
- * Users can also specifiy additional configuraiton directories relative - * to "/usr/share/alsa/" to search the included files, via alsaconf syntax - * .

- * - * For example, file A and file B are two text conf files for platform X, - * they will be installed to /usr/share/alsa/topology/platformx. If we - * need file A to include file B, in file A we can add:
- * - *
- *

- * - * ALSA conf will search and open an included file in the following order - * of priority: - * 1. directly open the file by its name; - * 2. search for the file name in "/usr/share/alsa"; - * 3. search for the file name in user specified subdirectories under - * "/usr/share/alsa". - * - * The order of the included files need not to be same as their - * dependencies, since the topology library will load them all before - * parsing their dependencies.
- * - * The configuration directories defined by a file will only be used to search - * the files included by this file. - */ - -/** Maximum number of channels supported in one control */ -#define SND_TPLG_MAX_CHAN 8 - -/** Topology context */ -typedef struct snd_tplg snd_tplg_t;

If + * this function returns `cgltf_result_success`, you have to call + * `cgltf_free()` on the created `cgltf_data*` variable. + * Note that contents of external files for buffers and images are not + * automatically loaded. You'll need to read these files yourself using + * URIs in the `cgltf_data` structure. + * + * `cgltf_options` is the struct passed to `cgltf_parse()` to control + * parts of the parsing process. You can use it to force the file type + * and provide memory allocation as well as file operation callbacks. + * Should be zero-initialized to trigger default behavior. + * + * `cgltf_data` is the struct allocated and filled by `cgltf_parse()`. + * It generally mirrors the glTF format as described by the spec (see + * https://github.com/KhronosGroup/glTF/tree/master/specification/2.0). + * + * `void cgltf_free(cgltf_data*)` frees the allocated `cgltf_data` + * variable. + * + * `cgltf_result cgltf_load_buffers(const cgltf_options*, cgltf_data*, + * const char* gltf_path)` can be optionally called to open and read buffer + * files using the `FILE*` APIs. The `gltf_path` argument is the path to + * the original glTF file, which allows the parser to resolve the path to + * buffer files. + * + * `cgltf_result cgltf_load_buffer_base64(const cgltf_options* options, + * cgltf_size size, const char* base64, void** out_data)` decodes + * base64-encoded data content. Used internally by `cgltf_load_buffers()`. + * This is useful when decoding data URIs in images. + * + * `cgltf_result cgltf_parse_file(const cgltf_options* options, const + * char* path, cgltf_data** out_data)` can be used to open the given + * file using `FILE*` APIs and parse the data using `cgltf_parse()`. + * + * `cgltf_result cgltf_validate(cgltf_data*)` can be used to do additional + * checks to make sure the parsed glTF data is valid. + * + * `cgltf_node_transform_local` converts the translation / rotation / scale properties of a node + * into a mat4. + * + * `cgltf_node_transform_world` calls `cgltf_node_transform_local` on every ancestor in order + * to compute the root-to-node transformation. + * + * `cgltf_accessor_unpack_floats` reads in the data from an accessor, applies sparse data (if any), + * and converts them to floating point. Assumes that `cgltf_load_buffers` has already been called. + * By passing null for the output pointer, users can find out how many floats are required in the + * output buffer. + * + * `cgltf_accessor_unpack_indices` reads in the index data from an accessor. Assumes that + * `cgltf_load_buffers` has already been called. By passing null for the output pointer, users can + * find out how many indices are required in the output buffer. Returns 0 if the accessor is + * sparse or if the output component size is less than the accessor's component size. + * + * `cgltf_num_components` is a tiny utility that tells you the dimensionality of + * a certain accessor type. This can be used before `cgltf_accessor_unpack_floats` to help allocate + * the necessary amount of memory. `cgltf_component_size` and `cgltf_calc_size` exist for + * similar purposes. + * + * `cgltf_accessor_read_float` reads a certain element from a non-sparse accessor and converts it to + * floating point, assuming that `cgltf_load_buffers` has already been called. The passed-in element + * size is the number of floats in the output buffer, which should be in the range [1, 16]. Returns + * false if the passed-in element_size is too small, or if the accessor is sparse. + * + * `cgltf_accessor_read_uint` is similar to its floating-point counterpart, but limited to reading + * vector types and does not support matrix types. The passed-in element size is the number of uints + * in the output buffer, which should be in the range [1, 4]. Returns false if the passed-in + * element_size is too small, or if the accessor is sparse. + * + * `cgltf_accessor_read_index` is similar to its floating-point counterpart, but it returns size_t + * and only works with single-component data types. + * + * `cgltf_copy_extras_json` allows users to retrieve the "extras" data that can be attached to many + * glTF objects (which can be arbitrary JSON data). This is a legacy function, consider using + * cgltf_extras::data directly instead. You can parse this data using your own JSON parser + * or, if you've included the cgltf implementation using the integrated JSMN JSON parser. + */ +#ifndef CGLTF_H_INCLUDED__ +#define CGLTF_H_INCLUDED__ + +#include +#include /* For uint8_t, uint32_t */ + +#ifdef __cplusplus +extern "C" { +#endif + +typedef size_t cgltf_size;

The +existing system of DRFLAC_MALLOC, DRFLAC_REALLOC and DRFLAC_FREE are still in place and will be used by default when no custom +allocation callbacks are specified. + +To use the new system, you pass in a pointer to a drflac_allocation_callbacks object to drflac_open() and family, like this: + + void* my_malloc(size_t sz, void* pUserData) + { + return malloc(sz); + } + void* my_realloc(void* p, size_t sz, void* pUserData) + { + return realloc(p, sz); + } + void my_free(void* p, void* pUserData) + { + free(p); + } + + ... + + drflac_allocation_callbacks allocationCallbacks; + allocationCallbacks.pUserData = &myData; + allocationCallbacks.onMalloc = my_malloc; + allocationCallbacks.onRealloc = my_realloc; + allocationCallbacks.onFree = my_free; + drflac* pFlac = drflac_open_file("my_file.flac", &allocationCallbacks); + +The advantage of this new system is that it allows you to specify user data which will be passed in to the allocation routines. + +Passing in null for the allocation callbacks object will cause dr_flac to use defaults which is the same as DRFLAC_MALLOC, +DRFLAC_REALLOC and DRFLAC_FREE and the equivalent of how it worked in previous versions. + +Every API that opens a drflac object now takes this extra parameter. These include the following: + + drflac_open() + drflac_open_relaxed() + drflac_open_with_metadata() + drflac_open_with_metadata_relaxed() + drflac_open_file() + drflac_open_file_with_metadata() + drflac_open_memory() + drflac_open_memory_with_metadata() + drflac_open_and_read_pcm_frames_s32() + drflac_open_and_read_pcm_frames_s16() + drflac_open_and_read_pcm_frames_f32() + drflac_open_file_and_read_pcm_frames_s32() + drflac_open_file_and_read_pcm_frames_s16() + drflac_open_file_and_read_pcm_frames_f32() + drflac_open_memory_and_read_pcm_frames_s32() + drflac_open_memory_and_read_pcm_frames_s16() + drflac_open_memory_and_read_pcm_frames_f32() + + + +Optimizations +------------- +Seeking performance has been greatly improved. A new binary search based seeking algorithm has been introduced which significantly +improves performance over the brute force method which was used when no seek table was present. Seek table based seeking also takes +advantage of the new binary search seeking system to further improve performance there as well. Note that this depends on CRC which +means it will be disabled when DR_FLAC_NO_CRC is used. + +The SSE4.1 pipeline has been cleaned up and optimized. You should see some improvements with decoding speed of 24-bit files in +particular. 16-bit streams should also see some improvement. + +drflac_read_pcm_frames_s16() has been optimized. Previously this sat on top of drflac_read_pcm_frames_s32() and performed it's s32 +to s16 conversion in a second pass. This is now all done in a single pass. This includes SSE2 and ARM NEON optimized paths. + +A minor optimization has been implemented for drflac_read_pcm_frames_s32(). This will now use an SSE2 optimized pipeline for stereo +channel reconstruction which is the last part of the decoding process. + +The ARM build has seen a few improvements. The CLZ (count leading zeroes) and REV (byte swap) instructions are now used when +compiling with GCC and Clang which is achieved using inline assembly. The CLZ instruction requires ARM architecture version 5 at +compile time and the REV instruction requires ARM architecture version 6. + +An ARM NEON optimized pipeline has been implemented. To enable this you'll need to add -mfpu=neon to the command line when compiling. + + +Removed APIs +------------ +The following APIs were deprecated in version 0.11.0 and have been completely removed in version 0.12.0: + + drflac_read_s32() -> drflac_read_pcm_frames_s32() + drflac_read_s16() -> drflac_read_pcm_frames_s16() + drflac_read_f32() -> drflac_read_pcm_frames_f32() + drflac_seek_to_sample() -> drflac_seek_to_pcm_frame() + drflac_open_and_decode_s32() -> drflac_open_and_read_pcm_frames_s32() + drflac_open_and_decode_s16() -> drflac_open_and_read_pcm_frames_s16() + drflac_open_and_decode_f32() -> drflac_open_and_read_pcm_frames_f32() + drflac_open_and_decode_file_s32() -> drflac_open_file_and_read_pcm_frames_s32() + drflac_open_and_decode_file_s16() -> drflac_open_file_and_read_pcm_frames_s16() + drflac_open_and_decode_file_f32() -> drflac_open_file_and_read_pcm_frames_f32() + drflac_open_and_decode_memory_s32() -> drflac_open_memory_and_read_pcm_frames_s32() + drflac_open_and_decode_memory_s16() -> drflac_open_memory_and_read_pcm_frames_s16() + drflac_open_and_decode_memory_f32() -> drflac_open_memroy_and_read_pcm_frames_f32() + +Prior versions of dr_flac operated on a per-sample basis whereas now it operates on PCM frames.

This brings dr_flac back to about the same class of efficiency as the reference implementation. -// - Add support for custom implementations of malloc(), realloc(), etc. -// - Add CRC checking to Ogg encapsulated streams. -// - Fix VC++ 6 build. This is only for the C++ compiler. The C compiler is not currently supported. -// - Bug fixes. -// -// v0.7 - 2017-07-23 -// - Add support for opening a stream without a header block. To do this, use drflac_open_relaxed() / drflac_open_with_metadata_relaxed(). -// -// v0.6 - 2017-07-22 -// - Add support for recovering from invalid frames. With this change, dr_flac will simply skip over invalid frames as if they -// never existed. Frames are checked against their sync code, the CRC-8 of the frame header and the CRC-16 of the whole frame. -// -// v0.5 - 2017-07-16 -// - Fix typos. -// - Change drflac_bool* types to unsigned. -// - Add CRC checking.

You must now use the channel count and sample rate reported by the MP3 stream itself, and all channel and sample rate conversion must be done +yourself. + + +Changes to Initialization +------------------------- +Previously, `drmp3_init()`, etc. took a pointer to a `drmp3_config` object that allowed you to customize the output channels and sample rate. This has been +removed. If you need the old behaviour you will need to convert the data yourself or just not upgrade. The following APIs have changed. + + `drmp3_init()` + `drmp3_init_memory()` + `drmp3_init_file()` + + +Miscellaneous Changes +--------------------- +Support for loading a file from a `wchar_t` string has been added via the `drmp3_init_file_w()` API. +*/ + +/* +Introducation +============= +dr_mp3 is a single file library.

You can request any number of PCM frames in each +call to `drmp3_read_pcm_frames_f32()` and it will return as many PCM frames as it can, up to the requested amount. + +You can also decode an entire file in one go with `drmp3_open_and_read_pcm_frames_f32()`, `drmp3_open_memory_and_read_pcm_frames_f32()` and +`drmp3_open_file_and_read_pcm_frames_f32()`. + + +Build Options +============= +#define these options before including this file. + +#define DR_MP3_NO_STDIO + Disable drmp3_init_file(), etc. + +#define DR_MP3_NO_SIMD + Disable SIMD optimizations. +*/ #ifndef dr_mp3_h #define dr_mp3_h @@ -65,165 +90,289 @@ extern "C" { #endif -#include +#define DRMP3_STRINGIFY(x) #x +#define DRMP3_XSTRINGIFY(x) DRMP3_STRINGIFY(x) -#if defined(_MSC_VER) && _MSC_VER < 1600 -typedef signed char drmp3_int8; -typedef unsigned char drmp3_uint8; -typedef signed short drmp3_int16; -typedef unsigned short drmp3_uint16; -typedef signed int drmp3_int32; -typedef unsigned int drmp3_uint32; -typedef signed __int64 drmp3_int64; -typedef unsigned __int64 drmp3_uint64; +#define DRMP3_VERSION_MAJOR 0 +#define DRMP3_VERSION_MINOR 6 +#define DRMP3_VERSION_REVISION 39 +#define DRMP3_VERSION_STRING DRMP3_XSTRINGIFY(DRMP3_VERSION_MAJOR) "."

The +existing system of DRMP3_MALLOC, DRMP3_REALLOC and DRMP3_FREE are still in place and will be used by default when no custom +allocation callbacks are specified. + +To use the new system, you pass in a pointer to a drmp3_allocation_callbacks object to drmp3_init() and family, like this: + + void* my_malloc(size_t sz, void* pUserData) + { + return malloc(sz); + } + void* my_realloc(void* p, size_t sz, void* pUserData) + { + return realloc(p, sz); + } + void my_free(void* p, void* pUserData) + { + free(p); + } + + ... + + drmp3_allocation_callbacks allocationCallbacks; + allocationCallbacks.pUserData = &myData; + allocationCallbacks.onMalloc = my_malloc; + allocationCallbacks.onRealloc = my_realloc; + allocationCallbacks.onFree = my_free; + drmp3_init_file(&mp3, "my_file.mp3", NULL, &allocationCallbacks); + +The advantage of this new system is that it allows you to specify user data which will be passed in to the allocation routines. + +Passing in null for the allocation callbacks object will cause dr_mp3 to use defaults which is the same as DRMP3_MALLOC, +DRMP3_REALLOC and DRMP3_FREE and the equivalent of how it worked in previous versions. + +Every API that opens a drmp3 object now takes this extra parameter. These include the following: + + drmp3_init() + drmp3_init_file() + drmp3_init_memory() + drmp3_open_and_read_pcm_frames_f32() + drmp3_open_and_read_pcm_frames_s16() + drmp3_open_memory_and_read_pcm_frames_f32() + drmp3_open_memory_and_read_pcm_frames_s16() + drmp3_open_file_and_read_pcm_frames_f32() + drmp3_open_file_and_read_pcm_frames_s16() + +Renamed APIs +------------ +The following APIs have been renamed for consistency with other dr_* libraries and to make it clear that they return PCM frame +counts rather than sample counts. + + drmp3_open_and_read_f32() -> drmp3_open_and_read_pcm_frames_f32() + drmp3_open_and_read_s16() -> drmp3_open_and_read_pcm_frames_s16() + drmp3_open_memory_and_read_f32() -> drmp3_open_memory_and_read_pcm_frames_f32() + drmp3_open_memory_and_read_s16() -> drmp3_open_memory_and_read_pcm_frames_s16() + drmp3_open_file_and_read_f32() -> drmp3_open_file_and_read_pcm_frames_f32() + drmp3_open_file_and_read_s16() -> drmp3_open_file_and_read_pcm_frames_s16() +*/ + +/* +REVISION HISTORY +================ +v0.6.39 - 2024-02-27 + - Fix a Wdouble-promotion warning. + +v0.6.38 - 2023-11-02 + - Fix build for ARMv6-M. + +v0.6.37 - 2023-07-07 + - Silence a static analysis warning. + +v0.6.36 - 2023-06-17 + - Fix an incorrect date in revision history.

To use it, do something like the following in one .c file. + + ```c + #define DR_WAV_IMPLEMENTATION + #include "dr_wav.h" + ``` + +You can then #include this file in other parts of the program as you would with any other header file. Do something like the following to read audio data: + + ```c + drwav wav; + if (!drwav_init_file(&wav, "my_song.wav", NULL)) { + // Error opening WAV file. + } + + drwav_int32* pDecodedInterleavedPCMFrames = malloc(wav.totalPCMFrameCount * wav.channels * sizeof(drwav_int32)); + size_t numberOfSamplesActuallyDecoded = drwav_read_pcm_frames_s32(&wav, wav.totalPCMFrameCount, pDecodedInterleavedPCMFrames); + + ... + + drwav_uninit(&wav); + ``` + +If you just want to quickly open and read the audio data in a single operation you can do something like this: + + ```c + unsigned int channels; + unsigned int sampleRate; + drwav_uint64 totalPCMFrameCount; + float* pSampleData = drwav_open_file_and_read_pcm_frames_f32("my_song.wav", &channels, &sampleRate, &totalPCMFrameCount, NULL); + if (pSampleData == NULL) { + // Error opening and reading WAV file. + } + + ... + + drwav_free(pSampleData, NULL); + ``` + +The examples above use versions of the API that convert the audio data to a consistent format (32-bit signed PCM, in this case), but you can still output the +audio data in its internal format (see notes below for supported formats): + + ```c + size_t framesRead = drwav_read_pcm_frames(&wav, wav.totalPCMFrameCount, pDecodedInterleavedPCMFrames); + ``` + +You can also read the raw bytes of audio data, which could be useful if dr_wav does not have native support for a particular data format: + + ```c + size_t bytesRead = drwav_read_raw(&wav, bytesToRead, pRawDataBuffer); + ``` + +dr_wav can also be used to output WAV files. This does not currently support compressed formats. To use this, look at `drwav_init_write()`, +`drwav_init_file_write()`, etc. Use `drwav_write_pcm_frames()` to write samples, or `drwav_write_raw()` to write raw data in the "data" chunk. + + ```c + drwav_data_format format; + format.container = drwav_container_riff; // <-- drwav_container_riff = normal WAV files, drwav_container_w64 = Sony Wave64. + format.format = DR_WAVE_FORMAT_PCM; // <-- Any of the DR_WAVE_FORMAT_* codes. + format.channels = 2; + format.sampleRate = 44100; + format.bitsPerSample = 16; + drwav_init_file_write(&wav, "data/recording.wav", &format, NULL); + + ... + + drwav_uint64 framesWritten = drwav_write_pcm_frames(pWav, frameCount, pSamples); + ``` + +Note that writing to AIFF or RIFX is not supported. + +dr_wav has support for decoding from a number of different encapsulation formats. See below for details. + + +Build Options +============= +#define these options before including this file. + +#define DR_WAV_NO_CONVERSION_API + Disables conversion APIs such as `drwav_read_pcm_frames_f32()` and `drwav_s16_to_f32()`. + +#define DR_WAV_NO_STDIO + Disables APIs that initialize a decoder from a file such as `drwav_init_file()`, `drwav_init_file_write()`, etc. + +#define DR_WAV_NO_WCHAR + Disables all functions ending with `_w`. Use this if your compiler does not provide wchar.h. Not required if DR_WAV_NO_STDIO is also defined. + + +Supported Encapsulations +======================== +- RIFF (Regular WAV) +- RIFX (Big-Endian) +- AIFF (Does not currently support ADPCM) +- RF64 +- W64 + +Note that AIFF and RIFX do not support write mode, nor do they support reading of metadata. + + +Supported Encodings +=================== +- Unsigned 8-bit PCM +- Signed 12-bit PCM +- Signed 16-bit PCM +- Signed 24-bit PCM +- Signed 32-bit PCM +- IEEE 32-bit floating point +- IEEE 64-bit floating point +- A-law and u-law +- Microsoft ADPCM +- IMA ADPCM (DVI, format code 0x11) + +8-bit PCM encodings are always assumed to be unsigned. Signed 8-bit encoding can only be read with `drwav_read_raw()`. + +Note that ADPCM is not currently supported with AIFF. Contributions welcome. + + +Notes +===== +- Samples are always interleaved. +- The default read function does not do any data conversion. Use `drwav_read_pcm_frames_f32()`, `drwav_read_pcm_frames_s32()` and `drwav_read_pcm_frames_s16()` + to read and convert audio data to 32-bit floating point, signed 32-bit integer and signed 16-bit integer samples respectively. +- dr_wav will try to read the WAV file as best it can, even if it's not strictly conformant to the WAV format. +*/ #ifndef dr_wav_h #define dr_wav_h -#include - -#if defined(_MSC_VER) && _MSC_VER < 1600 -typedef signed char drwav_int8; -typedef unsigned char drwav_uint8; -typedef signed short drwav_int16; -typedef unsigned short drwav_uint16; -typedef signed int drwav_int32; -typedef unsigned int drwav_uint32; -typedef signed __int64 drwav_int64; -typedef unsigned __int64 drwav_uint64; -#else -#include -typedef int8_t drwav_int8; -typedef uint8_t drwav_uint8; -typedef int16_t drwav_int16; -typedef uint16_t drwav_uint16; -typedef int32_t drwav_int32; -typedef uint32_t drwav_uint32; -typedef int64_t drwav_int64; -typedef uint64_t drwav_uint64; -#endif -typedef drwav_uint8 drwav_bool8; -typedef drwav_uint32 drwav_bool32; -#define DRWAV_TRUE 1 -#define DRWAV_FALSE 0 - #ifdef __cplusplus extern "C" { #endif -// Common data formats. +#define DRWAV_STRINGIFY(x) #x +#define DRWAV_XSTRINGIFY(x) DRWAV_STRINGIFY(x) + +#define DRWAV_VERSION_MAJOR 0 +#define DRWAV_VERSION_MINOR 13 +#define DRWAV_VERSION_REVISION 16 +#define DRWAV_VERSION_STRING DRWAV_XSTRINGIFY(DRWAV_VERSION_MAJOR) "."

Public domain. See "unlicense" statement at the end of this file. -// mini_al - v0.6b - 2018-02-03 -// -// David Reid - davidreidsoftware@gmail.com - -// ABOUT -// ===== -// mini_al is a small library for making it easy to connect to a playback or capture device and send -// or receive data from that device. -// -// mini_al uses an asynchronous API. Every device is created with it's own thread, with audio data -// being delivered to or from the device via a callback. Synchronous APIs are not supported in the -// interest of keeping the library as simple and light-weight as possible. -// -// Supported Backends: -// - WASAPI -// - DirectSound -// - WinMM -// - ALSA -// - OSS -// - OpenSL|ES / Android -// - OpenAL -// - SDL -// - Null (Silence) -// - ... and more in the future. -// - Core Audio (OSX, iOS) -// -// Supported Formats: -// - Unsigned 8-bit PCM -// - Signed 16-bit PCM -// - Signed 24-bit PCM (tightly packed) -// - Signed 32-bit PCM -// - IEEE 32-bit floating point PCM -// -// -// USAGE -// ===== -// mini_al is a single-file library. To use it, do something like the following in one .c file. -// #define MAL_IMPLEMENTATION -// #include "mini_al.h" -// -// You can then #include this file in other parts of the program as you would with any other header file. -// -// The implementation of this library will try #include-ing necessary headers for each backend. If you do not have -// the development packages for any particular backend you can disable it by #define-ing the appropriate MAL_NO_* -// option before the implementation. -// -// -// Building (Windows) -// ------------------ -// The Windows build should compile clean on all modern versions of MSVC without the need to configure any include -// paths nor link to any libraries. The same applies to MinGW/GCC and Clang. -// -// Building (Linux) -// ---------------- -// The Linux build uses ALSA for it's backend so you will need to install the relevant ALSA development packages -// for your preferred distro. It also uses pthreads. Dependencies are dynamically linked at runtime so you do not -// need to link to -lasound nor -lpthread. You will need to link to -ldl. -// -// Building (BSD) -// -------------- -// BSD build uses OSS. Requires linking to -lossaudio on {Open,Net}BSD, but not FreeBSD. -// -// Building (Emscripten) -// --------------------- -// The Emscripten build currently uses SDL 1.2 for it's backend which means specifying "-s USE_SDL=2" is unecessary -// as of this version. However, if in the future there is legitimate benefit or enough demand for SDL 2 to be used -// instead, you will need to specify this when compiling. -// -// -// Playback Example -// ---------------- -// mal_uint32 on_send_samples(mal_device* pDevice, mal_uint32 frameCount, void* pSamples) -// { -// // This callback is set at initialization time and will be called when a playback device needs more -// // data. You need to write as many frames as you can to pSamples (but no more than frameCount) and -// // then return the number of frames you wrote. -// // -// // The user data (pDevice->pUserData) is set by mal_device_init(). -// return (mal_uint32)drwav_read_f32((drwav*)pDevice->pUserData, frameCount * pDevice->channels, (float*)pSamples) / pDevice->channels; -// } -// -// ... -// -// mal_context context; -// if (mal_context_init(NULL, 0, NULL, &context) != MAL_SUCCESS) { -// printf("Failed to initialize context."); -// return -3; -// } -// -// mal_device_config config = mal_device_config_init_playback(mal_format_s16, wav.channels, wav.sampleRate, on_send_frames_to_device); -// -// mal_device device; -// mal_result result = mal_device_init(&context, mal_device_type_playback, NULL, &config, pMyData, &device); -// if (result != MAL_SUCCESS) { -// return -1; -// } -// -// mal_device_start(&device); // The device is sleeping by default so you'll need to start it manually. -// -// ... -// -// mal_device_uninit(&device); // This will stop the device so no need to do that manually. -// -// -// -// NOTES -// ===== -// - This library uses an asynchronous API for delivering and requesting audio data. Each device will have -// it's own worker thread which is managed by the library. -// - If mal_device_init() is called with a device that's not aligned to the platform's natural alignment -// boundary (4 bytes on 32-bit, 8 bytes on 64-bit), it will _not_ be thread-safe. The reason for this -// is that it depends on members of mal_device being correctly aligned for atomic assignments. -// - Sample data is always little-endian and interleaved. For example, mal_format_s16 means signed 16-bit -// integer samples, interleaved. Let me know if you need non-interleaved and I'll look into it. -// -// -// -// BACKEND NUANCES -// =============== -// - The absolute best latency I am able to get on DirectSound is about 10 milliseconds. This seems very -// consistent so I'm suspecting there's some kind of hard coded limit there or something. -// - DirectSound currently supports a maximum of 4 periods. -// - To capture audio on Android, remember to add the RECORD_AUDIO permission to your manifest: -// -// - UWP is only supported when compiling as C++. -// - UWP only supports default playback and capture devices. -// - UWP requires the Microphone capability to be enabled in the application's manifest (Package.appxmanifest): -// -// ... -// -// -// -// -// -// -// OPTIONS -// ======= -// #define these options before including this file. -// -// #define MAL_NO_WASAPI -// Disables the WASAPI backend. -// -// #define MAL_NO_DSOUND -// Disables the DirectSound backend. -// -// #define MAL_NO_WINMM -// Disables the WinMM backend. -// -// #define MAL_NO_ALSA -// Disables the ALSA backend. -// -// #define MAL_NO_OSS -// Disables the OSS backend. -// -// #define MAL_NO_OPENSL -// Disables the OpenSL|ES backend. -// -// #define MAL_NO_OPENAL -// Disables the OpenAL backend. -// -// #define MAL_NO_SDL -// Disables the SDL backend. -// -// #define MAL_NO_NULL -// Disables the null backend. -// -// #define MAL_DEFAULT_BUFFER_SIZE_IN_MILLISECONDS -// When a buffer size of 0 is specified when a device is initialized, it will default to a size with -// this number of milliseconds worth of data.

If you were using the mutex APIs before this version you'll -// need to update. -// - API CHANGE: SRC and DSP callbacks now take a pointer to a mal_src and mal_dsp object respectively. -// - API CHANGE: Improvements to event and thread APIs. These changes make these APIs more consistent. -// - Add support for SDL and Emscripten. -// - Simplify the build system further for when development packages for various backends are not installed. -// With this change, when the compiler supports __has_include, backends without the relevant development -// packages installed will be ignored. This fixes the build for old versions of MinGW. -// - Fixes to the Android build. -// - Add mal_convert_frames(). This is a high-level helper API for performing a one-time, bulk conversion of -// audio data to a different format. -// - Improvements to f32 -> u8/s16/s24/s32 conversion routines. -// - Fix a bug where the wrong value is returned from mal_device_start() for the OpenSL backend. -// - Fixes and improvements for Raspberry Pi. -// - Warning fixes. -// -// v0.5 - 2017-11-11 -// - API CHANGE: The mal_context_init() function now takes a pointer to a mal_context_config object for -// configuring the context. The works in the same kind of way as the device config. The rationale for this -// change is to give applications better control over context-level properties, add support for backend- -// specific configurations, and support extensibility without breaking the API. -// - API CHANGE: The alsa.preferPlugHW device config variable has been removed since it's not really useful for -// anything anymore. -// - ALSA: By default, device enumeration will now only enumerate over unique card/device pairs. Applications -// can enable verbose device enumeration by setting the alsa.useVerboseDeviceEnumeration context config -// variable. -// - ALSA: When opening a device in shared mode (the default), the dmix/dsnoop plugin will be prioritized. If -// this fails it will fall back to the hw plugin. With this change the preferExclusiveMode config is now -// honored. Note that this does not happen when alsa.useVerboseDeviceEnumeration is set to true (see above) -// which is by design. -// - ALSA: Add support for excluding the "null" device using the alsa.excludeNullDevice context config variable. -// - ALSA: Fix a bug with channel mapping which causes an assertion to fail. -// - Fix errors with enumeration when pInfo is set to NULL. -// - OSS: Fix a bug when starting a device when the client sends 0 samples for the initial buffer fill. -// -// v0.4 - 2017-11-05 -// - API CHANGE: The log callback is now per-context rather than per-device and as is thus now passed to -// mal_context_init(). The rationale for this change is that it allows applications to capture diagnostic -// messages at the context level. Previously this was only available at the device level. -// - API CHANGE: The device config passed to mal_device_init() is now const. -// - Added support for OSS which enables support on BSD platforms. -// - Added support for WinMM (waveOut/waveIn). -// - Added support for UWP (Universal Windows Platform) applications. Currently C++ only. -// - Added support for exclusive mode for selected backends. Currently supported on WASAPI. -// - POSIX builds no longer require explicit linking to libpthread (-lpthread). -// - ALSA: Explicit linking to libasound (-lasound) is no longer required. -// - ALSA: Latency improvements. -// - ALSA: Use MMAP mode where available. This can be disabled with the alsa.noMMap config. -// - ALSA: Use "hw" devices instead of "plughw" devices by default. This can be disabled with the -// alsa.preferPlugHW config. -// - WASAPI is now the highest priority backend on Windows platforms. -// - Fixed an error with sample rate conversion which was causing crackling when capturing. -// - Improved error handling. -// - Improved compiler support. -// - Miscellaneous bug fixes. -// -// v0.3 - 2017-06-19 -// - API CHANGE: Introduced the notion of a context. The context is the highest level object and is required for -// enumerating and creating devices. Now, applications must first create a context, and then use that to -// enumerate and create devices. The reason for this change is to ensure device enumeration and creation is -// tied to the same backend. In addition, some backends are better suited to this design. -// - API CHANGE: Removed the rewinding APIs because they're too inconsistent across the different backends, hard -// to test and maintain, and just generally unreliable. -// - Added helper APIs for initializing mal_device_config objects. -// - Null Backend: Fixed a crash when recording. -// - Fixed build for UWP. -// - Added support for f32 formats to the OpenSL|ES backend. -// - Added initial implementation of the WASAPI backend. -// - Added initial implementation of the OpenAL backend. -// - Added support for low quality linear sample rate conversion. -// - Added early support for basic channel mapping. -// -// v0.2 - 2016-10-28 -// - API CHANGE: Add user data pointer as the last parameter to mal_device_init(). The rationale for this -// change is to ensure the logging callback has access to the user data during initialization. -// - API CHANGE: Have device configuration properties be passed to mal_device_init() via a structure. Rationale: -// 1) The number of parameters is just getting too much. -// 2) It makes it a bit easier to add new configuration properties in the future. In particular, there's a -// chance there will be support added for backend-specific properties. -// - Dropped support for f64, A-law and Mu-law formats since they just aren't common enough to justify the -// added maintenance cost. -// - DirectSound: Increased the default buffer size for capture devices. -// - Added initial implementation of the OpenSL|ES backend. -// -// v0.1 - 2016-10-21 -// - Initial versioned release. - - -/* -This is free and unencumbered software released into the public domain. - -Anyone is free to copy, modify, publish, use, compile, sell, or -distribute this software, either in source code form or as a compiled -binary, for any purpose, commercial or non-commercial, and by any -means. - -In jurisdictions that recognize copyright laws, the author or authors -of this software dedicate any and all copyright interest in the -software to the public domain.

Introduction +=============== +To use miniaudio, include "miniaudio.h": + + ```c + #include "miniaudio.h" + ``` + +The implementation is contained in "miniaudio.c". Just compile this like any other source file. You +can include miniaudio.c if you want to compile your project as a single translation unit: + + ```c + #include "miniaudio.c" + ``` + +miniaudio includes both low level and high level APIs. The low level API is good for those who want +to do all of their mixing themselves and only require a light weight interface to the underlying +audio device. The high level API is good for those who have complex mixing and effect requirements. + +In miniaudio, objects are transparent structures. Unlike many other libraries, there are no handles +to opaque objects which means you need to allocate memory for objects yourself. In the examples +presented in this documentation you will often see objects declared on the stack. You need to be +careful when translating these examples to your own code so that you don't accidentally declare +your objects on the stack and then cause them to become invalid once the function returns. In +addition, you must ensure the memory address of your objects remain the same throughout their +lifetime. You therefore cannot be making copies of your objects. + +A config/init pattern is used throughout the entire library. The idea is that you set up a config +object and pass that into the initialization routine. The advantage to this system is that the +config object can be initialized with logical defaults and new properties added to it without +breaking the API. The config object can be allocated on the stack and does not need to be +maintained after initialization of the corresponding object. + + +1.1. Low Level API +------------------ +The low level API gives you access to the raw audio data of an audio device. It supports playback, +capture, full-duplex and loopback (WASAPI only). You can enumerate over devices to determine which +physical device(s) you want to connect to. + +The low level API uses the concept of a "device" as the abstraction for physical devices. The idea +is that you choose a physical device to emit or capture audio from, and then move data to/from the +device when miniaudio tells you to. Data is delivered to and from devices asynchronously via a +callback which you specify when initializing the device. + +When initializing the device you first need to configure it. The device configuration allows you to +specify things like the format of the data delivered via the callback, the size of the internal +buffer and the ID of the device you want to emit or capture audio from. + +Once you have the device configuration set up you can initialize the device. When initializing a +device you need to allocate memory for the device object beforehand. This gives the application +complete control over how the memory is allocated. In the example below we initialize a playback +device on the stack, but you could allocate it on the heap if that suits your situation better. + + ```c + void data_callback(ma_device* pDevice, void* pOutput, const void* pInput, ma_uint32 frameCount) + { + // In playback mode copy data to pOutput. In capture mode read data from pInput. In full-duplex mode, both + // pOutput and pInput will be valid and you can move data from pInput into pOutput. Never process more than + // frameCount frames. + } + + int main() + { + ma_device_config config = ma_device_config_init(ma_device_type_playback); + config.playback.format = ma_format_f32; // Set to ma_format_unknown to use the device's native format. + config.playback.channels = 2; // Set to 0 to use the device's native channel count. + config.sampleRate = 48000; // Set to 0 to use the device's native sample rate. + config.dataCallback = data_callback; // This function will be called when miniaudio needs more data. + config.pUserData = pMyCustomData; // Can be accessed from the device object (device.pUserData). + + ma_device device; + if (ma_device_init(NULL, &config, &device) != MA_SUCCESS) { + return -1; // Failed to initialize the device. + } + + ma_device_start(&device); // The device is sleeping by default so you'll need to start it manually. + + // Do something here. Probably your program's main loop. + + ma_device_uninit(&device); + return 0; + } + ``` + +In the example above, `data_callback()` is where audio data is written and read from the device. +The idea is in playback mode you cause sound to be emitted from the speakers by writing audio data +to the output buffer (`pOutput` in the example). In capture mode you read data from the input +buffer (`pInput`) to extract sound captured by the microphone. The `frameCount` parameter tells you +how many frames can be written to the output buffer and read from the input buffer. A "frame" is +one sample for each channel. For example, in a stereo stream (2 channels), one frame is 2 +samples: one for the left, one for the right. The channel count is defined by the device config. +The size in bytes of an individual sample is defined by the sample format which is also specified +in the device config. Multi-channel audio data is always interleaved, which means the samples for +each frame are stored next to each other in memory. For example, in a stereo stream the first pair +of samples will be the left and right samples for the first frame, the second pair of samples will +be the left and right samples for the second frame, etc. + +The configuration of the device is defined by the `ma_device_config` structure. The config object +is always initialized with `ma_device_config_init()`. It's important to always initialize the +config with this function as it initializes it with logical defaults and ensures your program +doesn't break when new members are added to the `ma_device_config` structure. The example above +uses a fairly simple and standard device configuration. The call to `ma_device_config_init()` takes +a single parameter, which is whether or not the device is a playback, capture, duplex or loopback +device (loopback devices are not supported on all backends). The `config.playback.format` member +sets the sample format which can be one of the following (all formats are native-endian): + + +---------------+----------------------------------------+---------------------------+ + | Symbol | Description | Range | + +---------------+----------------------------------------+---------------------------+ + | ma_format_f32 | 32-bit floating point | [-1, 1] | + | ma_format_s16 | 16-bit signed integer | [-32768, 32767] | + | ma_format_s24 | 24-bit signed integer (tightly packed) | [-8388608, 8388607] | + | ma_format_s32 | 32-bit signed integer | [-2147483648, 2147483647] | + | ma_format_u8 | 8-bit unsigned integer | [0, 255] | + +---------------+----------------------------------------+---------------------------+ + +The `config.playback.channels` member sets the number of channels to use with the device. The +channel count cannot exceed MA_MAX_CHANNELS. The `config.sampleRate` member sets the sample rate +(which must be the same for both playback and capture in full-duplex configurations). This is +usually set to 44100 or 48000, but can be set to anything. It's recommended to keep this between +8000 and 384000, however. + +Note that leaving the format, channel count and/or sample rate at their default values will result +in the internal device's native configuration being used which is useful if you want to avoid the +overhead of miniaudio's automatic data conversion. + +In addition to the sample format, channel count and sample rate, the data callback and user data +pointer are also set via the config. The user data pointer is not passed into the callback as a +parameter, but is instead set to the `pUserData` member of `ma_device` which you can access +directly since all miniaudio structures are transparent. + +Initializing the device is done with `ma_device_init()`. This will return a result code telling you +what went wrong, if anything. On success it will return `MA_SUCCESS`. After initialization is +complete the device will be in a stopped state. To start it, use `ma_device_start()`. +Uninitializing the device will stop it, which is what the example above does, but you can also stop +the device with `ma_device_stop()`. To resume the device simply call `ma_device_start()` again. +Note that it's important to never stop or start the device from inside the callback. This will +result in a deadlock. Instead you set a variable or signal an event indicating that the device +needs to stop and handle it in a different thread. The following APIs must never be called inside +the callback: + + ```c + ma_device_init() + ma_device_init_ex() + ma_device_uninit() + ma_device_start() + ma_device_stop() + ``` + +You must never try uninitializing and reinitializing a device inside the callback. You must also +never try to stop and start it from inside the callback. There are a few other things you shouldn't +do in the callback depending on your requirements, however this isn't so much a thread-safety +thing, but rather a real-time processing thing which is beyond the scope of this introduction. + +The example above demonstrates the initialization of a playback device, but it works exactly the +same for capture. All you need to do is change the device type from `ma_device_type_playback` to +`ma_device_type_capture` when setting up the config, like so: + + ```c + ma_device_config config = ma_device_config_init(ma_device_type_capture); + config.capture.format = MY_FORMAT; + config.capture.channels = MY_CHANNEL_COUNT; + ``` + +In the data callback you just read from the input buffer (`pInput` in the example above) and leave +the output buffer alone (it will be set to NULL when the device type is set to +`ma_device_type_capture`). + +These are the available device types and how you should handle the buffers in the callback: + + +-------------------------+--------------------------------------------------------+ + | Device Type | Callback Behavior | + +-------------------------+--------------------------------------------------------+ + | ma_device_type_playback | Write to output buffer, leave input buffer untouched. | + | ma_device_type_capture | Read from input buffer, leave output buffer untouched. | + | ma_device_type_duplex | Read from input buffer, write to output buffer. | + | ma_device_type_loopback | Read from input buffer, leave output buffer untouched. | + +-------------------------+--------------------------------------------------------+ + +You will notice in the example above that the sample format and channel count is specified +separately for playback and capture. This is to support different data formats between the playback +and capture devices in a full-duplex system. An example may be that you want to capture audio data +as a monaural stream (one channel), but output sound to a stereo speaker system. Note that if you +use different formats between playback and capture in a full-duplex configuration you will need to +convert the data yourself. There are functions available to help you do this which will be +explained later. + +The example above did not specify a physical device to connect to which means it will use the +operating system's default device. If you have multiple physical devices connected and you want to +use a specific one you will need to specify the device ID in the configuration, like so: + + ```c + config.playback.pDeviceID = pMyPlaybackDeviceID; // Only if requesting a playback or duplex device. + config.capture.pDeviceID = pMyCaptureDeviceID; // Only if requesting a capture, duplex or loopback device. + ``` + +To retrieve the device ID you will need to perform device enumeration, however this requires the +use of a new concept called the "context". Conceptually speaking the context sits above the device. +There is one context to many devices. The purpose of the context is to represent the backend at a +more global level and to perform operations outside the scope of an individual device. Mainly it is +used for performing run-time linking against backend libraries, initializing backends and +enumerating devices. The example below shows how to enumerate devices. + + ```c + ma_context context; + if (ma_context_init(NULL, 0, NULL, &context) != MA_SUCCESS) { + // Error. + } + + ma_device_info* pPlaybackInfos; + ma_uint32 playbackCount; + ma_device_info* pCaptureInfos; + ma_uint32 captureCount; + if (ma_context_get_devices(&context, &pPlaybackInfos, &playbackCount, &pCaptureInfos, &captureCount) != MA_SUCCESS) { + // Error. + } + + // Loop over each device info and do something with it. Here we just print the name with their index. You may want + // to give the user the opportunity to choose which device they'd prefer. + for (ma_uint32 iDevice = 0; iDevice < playbackCount; iDevice += 1) { + printf("%d - %s\n", iDevice, pPlaybackInfos[iDevice].name); + } + + ma_device_config config = ma_device_config_init(ma_device_type_playback); + config.playback.pDeviceID = &pPlaybackInfos[chosenPlaybackDeviceIndex].id; + config.playback.format = MY_FORMAT; + config.playback.channels = MY_CHANNEL_COUNT; + config.sampleRate = MY_SAMPLE_RATE; + config.dataCallback = data_callback; + config.pUserData = pMyCustomData; + + ma_device device; + if (ma_device_init(&context, &config, &device) != MA_SUCCESS) { + // Error + } + + ... + + ma_device_uninit(&device); + ma_context_uninit(&context); + ``` + +The first thing we do in this example is initialize a `ma_context` object with `ma_context_init()`. +The first parameter is a pointer to a list of `ma_backend` values which are used to override the +default backend priorities. When this is NULL, as in this example, miniaudio's default priorities +are used. The second parameter is the number of backends listed in the array pointed to by the +first parameter. The third parameter is a pointer to a `ma_context_config` object which can be +NULL, in which case defaults are used. The context configuration is used for setting the logging +callback, custom memory allocation callbacks, user-defined data and some backend-specific +configurations. + +Once the context has been initialized you can enumerate devices. In the example above we use the +simpler `ma_context_get_devices()`, however you can also use a callback for handling devices by +using `ma_context_enumerate_devices()`. When using `ma_context_get_devices()` you provide a pointer +to a pointer that will, upon output, be set to a pointer to a buffer containing a list of +`ma_device_info` structures. You also provide a pointer to an unsigned integer that will receive +the number of items in the returned buffer. Do not free the returned buffers as their memory is +managed internally by miniaudio. + +The `ma_device_info` structure contains an `id` member which is the ID you pass to the device +config. It also contains the name of the device which is useful for presenting a list of devices +to the user via the UI. + +When creating your own context you will want to pass it to `ma_device_init()` when initializing the +device. Passing in NULL, like we do in the first example, will result in miniaudio creating the +context for you, which you don't want to do since you've already created a context. Note that +internally the context is only tracked by it's pointer which means you must not change the location +of the `ma_context` object. If this is an issue, consider using `malloc()` to allocate memory for +the context. + + +1.2. High Level API +------------------- +The high level API consists of three main parts: + + * Resource management for loading and streaming sounds. + * A node graph for advanced mixing and effect processing. + * A high level "engine" that wraps around the resource manager and node graph. + +The resource manager (`ma_resource_manager`) is used for loading sounds. It supports loading sounds +fully into memory and also streaming. It will also deal with reference counting for you which +avoids the same sound being loaded multiple times. + +The node graph is used for mixing and effect processing. The idea is that you connect a number of +nodes into the graph by connecting each node's outputs to another node's inputs. Each node can +implement its own effect. By chaining nodes together, advanced mixing and effect processing can +be achieved. + +The engine encapsulates both the resource manager and the node graph to create a simple, easy to +use high level API. The resource manager and node graph APIs are covered in more later sections of +this manual. + +The code below shows how you can initialize an engine using it's default configuration. + + ```c + ma_result result; + ma_engine engine; + + result = ma_engine_init(NULL, &engine); + if (result != MA_SUCCESS) { + return result; // Failed to initialize the engine. + } + ``` + +This creates an engine instance which will initialize a device internally which you can access with +`ma_engine_get_device()`. It will also initialize a resource manager for you which can be accessed +with `ma_engine_get_resource_manager()`. The engine itself is a node graph (`ma_node_graph`) which +means you can pass a pointer to the engine object into any of the `ma_node_graph` APIs (with a +cast). Alternatively, you can use `ma_engine_get_node_graph()` instead of a cast. + +Note that all objects in miniaudio, including the `ma_engine` object in the example above, are +transparent structures. There are no handles to opaque structures in miniaudio which means you need +to be mindful of how you declare them. In the example above we are declaring it on the stack, but +this will result in the struct being invalidated once the function encapsulating it returns. If +allocating the engine on the heap is more appropriate, you can easily do so with a standard call +to `malloc()` or whatever heap allocation routine you like: + + ```c + ma_engine* pEngine = malloc(sizeof(*pEngine)); + ``` + +The `ma_engine` API uses the same config/init pattern used all throughout miniaudio. To configure +an engine, you can fill out a `ma_engine_config` object and pass it into the first parameter of +`ma_engine_init()`: + + ```c + ma_result result; + ma_engine engine; + ma_engine_config engineConfig; + + engineConfig = ma_engine_config_init(); + engineConfig.pResourceManager = &myCustomResourceManager; // <-- Initialized as some earlier stage. + + result = ma_engine_init(&engineConfig, &engine); + if (result != MA_SUCCESS) { + return result; + } + ``` + +This creates an engine instance using a custom config. In this particular example it's showing how +you can specify a custom resource manager rather than having the engine initialize one internally. +This is particularly useful if you want to have multiple engine's share the same resource manager. + +The engine must be uninitialized with `ma_engine_uninit()` when it's no longer needed. + +By default the engine will be started, but nothing will be playing because no sounds have been +initialized. The easiest but least flexible way of playing a sound is like so: + + ```c + ma_engine_play_sound(&engine, "my_sound.wav", NULL); + ``` + +This plays what miniaudio calls an "inline" sound. It plays the sound once, and then puts the +internal sound up for recycling. The last parameter is used to specify which sound group the sound +should be associated with which will be explained later. This particular way of playing a sound is +simple, but lacks flexibility and features. A more flexible way of playing a sound is to first +initialize a sound: + + ```c + ma_result result; + ma_sound sound; + + result = ma_sound_init_from_file(&engine, "my_sound.wav", 0, NULL, NULL, &sound); + if (result != MA_SUCCESS) { + return result; + } + + ma_sound_start(&sound); + ``` + +This returns a `ma_sound` object which represents a single instance of the specified sound file. If +you want to play the same file multiple times simultaneously, you need to create one sound for each +instance. + +Sounds should be uninitialized with `ma_sound_uninit()`. + +Sounds are not started by default. Start a sound with `ma_sound_start()` and stop it with +`ma_sound_stop()`. When a sound is stopped, it is not rewound to the start. Use +`ma_sound_seek_to_pcm_frame(&sound, 0)` to seek back to the start of a sound. By default, starting +and stopping sounds happens immediately, but sometimes it might be convenient to schedule the sound +the be started and/or stopped at a specific time. This can be done with the following functions: + + ```c + ma_sound_set_start_time_in_pcm_frames() + ma_sound_set_start_time_in_milliseconds() + ma_sound_set_stop_time_in_pcm_frames() + ma_sound_set_stop_time_in_milliseconds() + ``` + +The start/stop time needs to be specified based on the absolute timer which is controlled by the +engine. The current global time in PCM frames can be retrieved with +`ma_engine_get_time_in_pcm_frames()`. The engine's global time can be changed with +`ma_engine_set_time_in_pcm_frames()` for synchronization purposes if required. Note that scheduling +a start time still requires an explicit call to `ma_sound_start()` before anything will play: + + ```c + ma_sound_set_start_time_in_pcm_frames(&sound, ma_engine_get_time_in_pcm_frames(&engine) + (ma_engine_get_sample_rate(&engine) * 2); + ma_sound_start(&sound); + ``` + +The third parameter of `ma_sound_init_from_file()` is a set of flags that control how the sound be +loaded and a few options on which features should be enabled for that sound. By default, the sound +is synchronously loaded fully into memory straight from the file system without any kind of +decoding. If you want to decode the sound before storing it in memory, you need to specify the +`MA_SOUND_FLAG_DECODE` flag. This is useful if you want to incur the cost of decoding at an earlier +stage, such as a loading stage. Without this option, decoding will happen dynamically at mixing +time which might be too expensive on the audio thread. + +If you want to load the sound asynchronously, you can specify the `MA_SOUND_FLAG_ASYNC` flag. This +will result in `ma_sound_init_from_file()` returning quickly, but the sound will not start playing +until the sound has had some audio decoded. + +The fourth parameter is a pointer to sound group. A sound group is used as a mechanism to organise +sounds into groups which have their own effect processing and volume control. An example is a game +which might have separate groups for sfx, voice and music. Each of these groups have their own +independent volume control. Use `ma_sound_group_init()` or `ma_sound_group_init_ex()` to initialize +a sound group. + +Sounds and sound groups are nodes in the engine's node graph and can be plugged into any `ma_node` +API. This makes it possible to connect sounds and sound groups to effect nodes to produce complex +effect chains. + +A sound can have its volume changed with `ma_sound_set_volume()`. If you prefer decibel volume +control you can use `ma_volume_db_to_linear()` to convert from decibel representation to linear. + +Panning and pitching is supported with `ma_sound_set_pan()` and `ma_sound_set_pitch()`. If you know +a sound will never have its pitch changed with `ma_sound_set_pitch()` or via the doppler effect, +you can specify the `MA_SOUND_FLAG_NO_PITCH` flag when initializing the sound for an optimization. + +By default, sounds and sound groups have spatialization enabled. If you don't ever want to +spatialize your sounds, initialize the sound with the `MA_SOUND_FLAG_NO_SPATIALIZATION` flag. The +spatialization model is fairly simple and is roughly on feature parity with OpenAL. HRTF and +environmental occlusion are not currently supported, but planned for the future. The supported +features include: + + * Sound and listener positioning and orientation with cones + * Attenuation models: none, inverse, linear and exponential + * Doppler effect + +Sounds can be faded in and out with `ma_sound_set_fade_in_pcm_frames()`. + +To check if a sound is currently playing, you can use `ma_sound_is_playing()`. To check if a sound +is at the end, use `ma_sound_at_end()`. Looping of a sound can be controlled with +`ma_sound_set_looping()`. Use `ma_sound_is_looping()` to check whether or not the sound is looping. + + + +2. Building +=========== +miniaudio should work cleanly out of the box without the need to download or install any +dependencies. See below for platform-specific details. + +Note that GCC and Clang require `-msse2`, `-mavx2`, etc. for SIMD optimizations. + +If you get errors about undefined references to `__sync_val_compare_and_swap_8`, `__atomic_load_8`, +etc. you need to link with `-latomic`. + + +2.1. Windows +------------ +The Windows build should compile cleanly on all popular compilers without the need to configure any +include paths nor link to any libraries. + +The UWP build may require linking to mmdevapi.lib if you get errors about an unresolved external +symbol for `ActivateAudioInterfaceAsync()`. + + +2.2. macOS and iOS +------------------ +The macOS build should compile cleanly without the need to download any dependencies nor link to +any libraries or frameworks. The iOS build needs to be compiled as Objective-C and will need to +link the relevant frameworks but should compile cleanly out of the box with Xcode. Compiling +through the command line requires linking to `-lpthread` and `-lm`. + +Due to the way miniaudio links to frameworks at runtime, your application may not pass Apple's +notarization process. To fix this there are two options. The first is to compile with +`-DMA_NO_RUNTIME_LINKING` which in turn will require linking with +`-framework CoreFoundation -framework CoreAudio -framework AudioToolbox`. If you get errors about +AudioToolbox, try with `-framework AudioUnit` instead. You may get this when using older versions +of iOS. Alternatively, if you would rather keep using runtime linking you can add the following to +your entitlements.xcent file: + + ``` + com.apple.security.cs.allow-dyld-environment-variables + + com.apple.security.cs.allow-unsigned-executable-memory + + ``` + +See this discussion for more info: https://github.com/mackron/miniaudio/issues/203. + + +2.3. Linux +---------- +The Linux build only requires linking to `-ldl`, `-lpthread` and `-lm`. You do not need any +development packages. You may need to link with `-latomic` if you're compiling for 32-bit ARM. + + +2.4. BSD +-------- +The BSD build only requires linking to `-lpthread` and `-lm`. NetBSD uses audio(4), OpenBSD uses +sndio and FreeBSD uses OSS. You may need to link with `-latomic` if you're compiling for 32-bit +ARM. + + +2.5. Android +------------ +AAudio is the highest priority backend on Android. This should work out of the box without needing +any kind of compiler configuration. Support for AAudio starts with Android 8 which means older +versions will fall back to OpenSL|ES which requires API level 16+. + +There have been reports that the OpenSL|ES backend fails to initialize on some Android based +devices due to `dlopen()` failing to open "libOpenSLES.so". If this happens on your platform +you'll need to disable run-time linking with `MA_NO_RUNTIME_LINKING` and link with -lOpenSLES. + + +2.6. Emscripten +--------------- +The Emscripten build emits Web Audio JavaScript directly and should compile cleanly out of the box. +You cannot use `-std=c*` compiler flags, nor `-ansi`. + +You can enable the use of AudioWorkets by defining `MA_ENABLE_AUDIO_WORKLETS` and then compiling +with the following options: + + -sAUDIO_WORKLET=1 -sWASM_WORKERS=1 -sASYNCIFY + +An example for compiling with AudioWorklet support might look like this: + + emcc program.c -o bin/program.html -DMA_ENABLE_AUDIO_WORKLETS -sAUDIO_WORKLET=1 -sWASM_WORKERS=1 -sASYNCIFY + +To run locally, you'll need to use emrun: + + emrun bin/program.html + + + +2.7.

Definitions +============== +This section defines common terms used throughout miniaudio. Unfortunately there is often ambiguity +in the use of terms throughout the audio space, so this section is intended to clarify how miniaudio +uses each term. + +3.1. Sample +----------- +A sample is a single unit of audio data. If the sample format is f32, then one sample is one 32-bit +floating point number. + +3.2. Frame / PCM Frame +---------------------- +A frame is a group of samples equal to the number of channels. For a stereo stream a frame is 2 +samples, a mono frame is 1 sample, a 5.1 surround sound frame is 6 samples, etc. The terms "frame" +and "PCM frame" are the same thing in miniaudio. Note that this is different to a compressed frame. +If ever miniaudio needs to refer to a compressed frame, such as a FLAC frame, it will always +clarify what it's referring to with something like "FLAC frame". + +3.3. Channel +------------ +A stream of monaural audio that is emitted from an individual speaker in a speaker system, or +received from an individual microphone in a microphone system. A stereo stream has two channels (a +left channel, and a right channel), a 5.1 surround sound system has 6 channels, etc. Some audio +systems refer to a channel as a complex audio stream that's mixed with other channels to produce +the final mix - this is completely different to miniaudio's use of the term "channel" and should +not be confused. + +3.4. Sample Rate +---------------- +The sample rate in miniaudio is always expressed in Hz, such as 44100, 48000, etc. It's the number +of PCM frames that are processed per second. + +3.5. Formats +------------ +Throughout miniaudio you will see references to different sample formats: + + +---------------+----------------------------------------+---------------------------+ + | Symbol | Description | Range | + +---------------+----------------------------------------+---------------------------+ + | ma_format_f32 | 32-bit floating point | [-1, 1] | + | ma_format_s16 | 16-bit signed integer | [-32768, 32767] | + | ma_format_s24 | 24-bit signed integer (tightly packed) | [-8388608, 8388607] | + | ma_format_s32 | 32-bit signed integer | [-2147483648, 2147483647] | + | ma_format_u8 | 8-bit unsigned integer | [0, 255] | + +---------------+----------------------------------------+---------------------------+ + +All formats are native-endian. + + + +4. Data Sources +=============== +The data source abstraction in miniaudio is used for retrieving audio data from some source. A few +examples include `ma_decoder`, `ma_noise` and `ma_waveform`. You will need to be familiar with data +sources in order to make sense of some of the higher level concepts in miniaudio. + +The `ma_data_source` API is a generic interface for reading from a data source. Any object that +implements the data source interface can be plugged into any `ma_data_source` function. + +To read data from a data source: + + ```c + ma_result result; + ma_uint64 framesRead; + + result = ma_data_source_read_pcm_frames(pDataSource, pFramesOut, frameCount, &framesRead); + if (result != MA_SUCCESS) { + return result; // Failed to read data from the data source. + } + ``` + +If you don't need the number of frames that were successfully read you can pass in `NULL` to the +`pFramesRead` parameter. If this returns a value less than the number of frames requested it means +the end of the file has been reached. `MA_AT_END` will be returned only when the number of frames +read is 0. + +When calling any data source function, with the exception of `ma_data_source_init()` and +`ma_data_source_uninit()`, you can pass in any object that implements a data source. For example, +you could plug in a decoder like so: + + ```c + ma_result result; + ma_uint64 framesRead; + ma_decoder decoder; // <-- This would be initialized with `ma_decoder_init_*()`. + + result = ma_data_source_read_pcm_frames(&decoder, pFramesOut, frameCount, &framesRead); + if (result != MA_SUCCESS) { + return result; // Failed to read data from the decoder. + } + ``` + +If you want to seek forward you can pass in `NULL` to the `pFramesOut` parameter. Alternatively you +can use `ma_data_source_seek_pcm_frames()`. + +To seek to a specific PCM frame: + + ```c + result = ma_data_source_seek_to_pcm_frame(pDataSource, frameIndex); + if (result != MA_SUCCESS) { + return result; // Failed to seek to PCM frame. + } + ``` + +You can retrieve the total length of a data source in PCM frames, but note that some data sources +may not have the notion of a length, such as noise and waveforms, and others may just not have a +way of determining the length such as some decoders. To retrieve the length: + + ```c + ma_uint64 length; + + result = ma_data_source_get_length_in_pcm_frames(pDataSource, &length); + if (result != MA_SUCCESS) { + return result; // Failed to retrieve the length. + } + ``` + +Care should be taken when retrieving the length of a data source where the underlying decoder is +pulling data from a data stream with an undefined length, such as internet radio or some kind of +broadcast. If you do this, `ma_data_source_get_length_in_pcm_frames()` may never return. + +The current position of the cursor in PCM frames can also be retrieved: + + ```c + ma_uint64 cursor; + + result = ma_data_source_get_cursor_in_pcm_frames(pDataSource, &cursor); + if (result != MA_SUCCESS) { + return result; // Failed to retrieve the cursor. + } + ``` + +You will often need to know the data format that will be returned after reading. This can be +retrieved like so: + + ```c + ma_format format; + ma_uint32 channels; + ma_uint32 sampleRate; + ma_channel channelMap[MA_MAX_CHANNELS]; + + result = ma_data_source_get_data_format(pDataSource, &format, &channels, &sampleRate, channelMap, MA_MAX_CHANNELS); + if (result != MA_SUCCESS) { + return result; // Failed to retrieve data format. + } + ``` + +If you do not need a specific data format property, just pass in NULL to the respective parameter. + +There may be cases where you want to implement something like a sound bank where you only want to +read data within a certain range of the underlying data. To do this you can use a range: + + ```c + result = ma_data_source_set_range_in_pcm_frames(pDataSource, rangeBegInFrames, rangeEndInFrames); + if (result != MA_SUCCESS) { + return result; // Failed to set the range. + } + ``` + +This is useful if you have a sound bank where many sounds are stored in the same file and you want +the data source to only play one of those sub-sounds. Note that once the range is set, everything +that takes a position, such as cursors and loop points, should always be relatvie to the start of +the range. When the range is set, any previously defined loop point will be reset. + +Custom loop points can also be used with data sources. By default, data sources will loop after +they reach the end of the data source, but if you need to loop at a specific location, you can do +the following: + + ```c + result = ma_data_set_loop_point_in_pcm_frames(pDataSource, loopBegInFrames, loopEndInFrames); + if (result != MA_SUCCESS) { + return result; // Failed to set the loop point. + } + ``` + +The loop point is relative to the current range. + +It's sometimes useful to chain data sources together so that a seamless transition can be achieved. +To do this, you can use chaining: + + ```c + ma_decoder decoder1; + ma_decoder decoder2; + + // ... initialize decoders with ma_decoder_init_*() ... + + result = ma_data_source_set_next(&decoder1, &decoder2); + if (result != MA_SUCCESS) { + return result; // Failed to set the next data source. + } + + result = ma_data_source_read_pcm_frames(&decoder1, pFramesOut, frameCount, pFramesRead); + if (result != MA_SUCCESS) { + return result; // Failed to read from the decoder. + } + ``` + +In the example above we're using decoders. When reading from a chain, you always want to read from +the top level data source in the chain. In the example above, `decoder1` is the top level data +source in the chain. When `decoder1` reaches the end, `decoder2` will start seamlessly without any +gaps. + +Note that when looping is enabled, only the current data source will be looped. You can loop the +entire chain by linking in a loop like so: + + ```c + ma_data_source_set_next(&decoder1, &decoder2); // decoder1 -> decoder2 + ma_data_source_set_next(&decoder2, &decoder1); // decoder2 -> decoder1 (loop back to the start). + ``` + +Note that setting up chaining is not thread safe, so care needs to be taken if you're dynamically +changing links while the audio thread is in the middle of reading. + +Do not use `ma_decoder_seek_to_pcm_frame()` as a means to reuse a data source to play multiple +instances of the same sound simultaneously. This can be extremely inefficient depending on the type +of data source and can result in glitching due to subtle changes to the state of internal filters. +Instead, initialize multiple data sources for each instance. + + +4.1. Custom Data Sources +------------------------ +You can implement a custom data source by implementing the functions in `ma_data_source_vtable`. +Your custom object must have `ma_data_source_base` as it's first member: + + ```c + struct my_data_source + { + ma_data_source_base base; + ... + }; + ``` + +In your initialization routine, you need to call `ma_data_source_init()` in order to set up the +base object (`ma_data_source_base`): + + ```c + static ma_result my_data_source_read(ma_data_source* pDataSource, void* pFramesOut, ma_uint64 frameCount, ma_uint64* pFramesRead) + { + // Read data here. Output in the same format returned by my_data_source_get_data_format(). + } + + static ma_result my_data_source_seek(ma_data_source* pDataSource, ma_uint64 frameIndex) + { + // Seek to a specific PCM frame here. Return MA_NOT_IMPLEMENTED if seeking is not supported. + } + + static ma_result my_data_source_get_data_format(ma_data_source* pDataSource, ma_format* pFormat, ma_uint32* pChannels, ma_uint32* pSampleRate, ma_channel* pChannelMap, size_t channelMapCap) + { + // Return the format of the data here. + } + + static ma_result my_data_source_get_cursor(ma_data_source* pDataSource, ma_uint64* pCursor) + { + // Retrieve the current position of the cursor here. Return MA_NOT_IMPLEMENTED and set *pCursor to 0 if there is no notion of a cursor. + } + + static ma_result my_data_source_get_length(ma_data_source* pDataSource, ma_uint64* pLength) + { + // Retrieve the length in PCM frames here. Return MA_NOT_IMPLEMENTED and set *pLength to 0 if there is no notion of a length or if the length is unknown. + } + + static ma_data_source_vtable g_my_data_source_vtable = + { + my_data_source_read, + my_data_source_seek, + my_data_source_get_data_format, + my_data_source_get_cursor, + my_data_source_get_length + }; + + ma_result my_data_source_init(my_data_source* pMyDataSource) + { + ma_result result; + ma_data_source_config baseConfig; + + baseConfig = ma_data_source_config_init(); + baseConfig.vtable = &g_my_data_source_vtable; + + result = ma_data_source_init(&baseConfig, &pMyDataSource->base); + if (result != MA_SUCCESS) { + return result; + } + + // ... do the initialization of your custom data source here ... + + return MA_SUCCESS; + } + + void my_data_source_uninit(my_data_source* pMyDataSource) + { + // ... do the uninitialization of your custom data source here ... + + // You must uninitialize the base data source. + ma_data_source_uninit(&pMyDataSource->base); + } + ``` + +Note that `ma_data_source_init()` and `ma_data_source_uninit()` are never called directly outside +of the custom data source. It's up to the custom data source itself to call these within their own +init/uninit functions. + + + +5. Engine +========= +The `ma_engine` API is a high level API for managing and mixing sounds and effect processing. The +`ma_engine` object encapsulates a resource manager and a node graph, both of which will be +explained in more detail later. + +Sounds are called `ma_sound` and are created from an engine. Sounds can be associated with a mixing +group called `ma_sound_group` which are also created from the engine. Both `ma_sound` and +`ma_sound_group` objects are nodes within the engine's node graph. + +When the engine is initialized, it will normally create a device internally. If you would rather +manage the device yourself, you can do so and just pass a pointer to it via the engine config when +you initialize the engine. You can also just use the engine without a device, which again can be +configured via the engine config. + +The most basic way to initialize the engine is with a default config, like so: + + ```c + ma_result result; + ma_engine engine; + + result = ma_engine_init(NULL, &engine); + if (result != MA_SUCCESS) { + return result; // Failed to initialize the engine. + } + ``` + +This will result in the engine initializing a playback device using the operating system's default +device. This will be sufficient for many use cases, but if you need more flexibility you'll want to +configure the engine with an engine config: + + ```c + ma_result result; + ma_engine engine; + ma_engine_config engineConfig; + + engineConfig = ma_engine_config_init(); + engineConfig.pDevice = &myDevice; + + result = ma_engine_init(&engineConfig, &engine); + if (result != MA_SUCCESS) { + return result; // Failed to initialize the engine. + } + ``` + +In the example above we're passing in a pre-initialized device. Since the caller is the one in +control of the device's data callback, it's their responsibility to manually call +`ma_engine_read_pcm_frames()` from inside their data callback: + + ```c + void playback_data_callback(ma_device* pDevice, void* pOutput, const void* pInput, ma_uint32 frameCount) + { + ma_engine_read_pcm_frames(&g_Engine, pOutput, frameCount, NULL); + } + ``` + +You can also use the engine independent of a device entirely: + + ```c + ma_result result; + ma_engine engine; + ma_engine_config engineConfig; + + engineConfig = ma_engine_config_init(); + engineConfig.noDevice = MA_TRUE; + engineConfig.channels = 2; // Must be set when not using a device. + engineConfig.sampleRate = 48000; // Must be set when not using a device. + + result = ma_engine_init(&engineConfig, &engine); + if (result != MA_SUCCESS) { + return result; // Failed to initialize the engine. + } + ``` + +Note that when you're not using a device, you must set the channel count and sample rate in the +config or else miniaudio won't know what to use (miniaudio will use the device to determine this +normally). When not using a device, you need to use `ma_engine_read_pcm_frames()` to process audio +data from the engine. This kind of setup is useful if you want to do something like offline +processing or want to use a different audio system for playback such as SDL. + +When a sound is loaded it goes through a resource manager. By default the engine will initialize a +resource manager internally, but you can also specify a pre-initialized resource manager: + + ```c + ma_result result; + ma_engine engine1; + ma_engine engine2; + ma_engine_config engineConfig; + + engineConfig = ma_engine_config_init(); + engineConfig.pResourceManager = &myResourceManager; + + ma_engine_init(&engineConfig, &engine1); + ma_engine_init(&engineConfig, &engine2); + ``` + +In this example we are initializing two engines, both of which are sharing the same resource +manager. This is especially useful for saving memory when loading the same file across multiple +engines. If you were not to use a shared resource manager, each engine instance would use their own +which would result in any sounds that are used between both engine's being loaded twice. By using +a shared resource manager, it would only be loaded once. Using multiple engine's is useful when you +need to output to multiple playback devices, such as in a local multiplayer game where each player +is using their own set of headphones. + +By default an engine will be in a started state. To make it so the engine is not automatically +started you can configure it as such: + + ```c + engineConfig.noAutoStart = MA_TRUE; + + // The engine will need to be started manually. + ma_engine_start(&engine); + + // Later on the engine can be stopped with ma_engine_stop(). + ma_engine_stop(&engine); + ``` + +The concept of starting or stopping an engine is only relevant when using the engine with a +device. Attempting to start or stop an engine that is not associated with a device will result in +`MA_INVALID_OPERATION`. + +The master volume of the engine can be controlled with `ma_engine_set_volume()` which takes a +linear scale, with 0 resulting in silence and anything above 1 resulting in amplification. If you +prefer decibel based volume control, use `ma_volume_db_to_linear()` to convert from dB to linear. + +When a sound is spatialized, it is done so relative to a listener. An engine can be configured to +have multiple listeners which can be configured via the config: + + ```c + engineConfig.listenerCount = 2; + ``` + +The maximum number of listeners is restricted to `MA_ENGINE_MAX_LISTENERS`. By default, when a +sound is spatialized, it will be done so relative to the closest listener. You can also pin a sound +to a specific listener which will be explained later. Listener's have a position, direction, cone, +and velocity (for doppler effect). A listener is referenced by an index, the meaning of which is up +to the caller (the index is 0 based and cannot go beyond the listener count, minus 1). The +position, direction and velocity are all specified in absolute terms: + + ```c + ma_engine_listener_set_position(&engine, listenerIndex, worldPosX, worldPosY, worldPosZ); + ``` + +The direction of the listener represents it's forward vector. The listener's up vector can also be +specified and defaults to +1 on the Y axis. + + ```c + ma_engine_listener_set_direction(&engine, listenerIndex, forwardX, forwardY, forwardZ); + ma_engine_listener_set_world_up(&engine, listenerIndex, 0, 1, 0); + ``` + +The engine supports directional attenuation. The listener can have a cone the controls how sound is +attenuated based on the listener's direction. When a sound is between the inner and outer cones, it +will be attenuated between 1 and the cone's outer gain: + + ```c + ma_engine_listener_set_cone(&engine, listenerIndex, innerAngleInRadians, outerAngleInRadians, outerGain); + ``` + +When a sound is inside the inner code, no directional attenuation is applied. When the sound is +outside of the outer cone, the attenuation will be set to `outerGain` in the example above. When +the sound is in between the inner and outer cones, the attenuation will be interpolated between 1 +and the outer gain. + +The engine's coordinate system follows the OpenGL coordinate system where positive X points right, +positive Y points up and negative Z points forward. + +The simplest and least flexible way to play a sound is like so: + + ```c + ma_engine_play_sound(&engine, "my_sound.wav", pGroup); + ``` + +This is a "fire and forget" style of function. The engine will manage the `ma_sound` object +internally. When the sound finishes playing, it'll be put up for recycling. For more flexibility +you'll want to initialize a sound object: + + ```c + ma_sound sound; + + result = ma_sound_init_from_file(&engine, "my_sound.wav", flags, pGroup, NULL, &sound); + if (result != MA_SUCCESS) { + return result; // Failed to load sound. + } + ``` + +Sounds need to be uninitialized with `ma_sound_uninit()`. + +The example above loads a sound from a file. If the resource manager has been disabled you will not +be able to use this function and instead you'll need to initialize a sound directly from a data +source: + + ```c + ma_sound sound; + + result = ma_sound_init_from_data_source(&engine, &dataSource, flags, pGroup, &sound); + if (result != MA_SUCCESS) { + return result; + } + ``` + +Each `ma_sound` object represents a single instance of the sound. If you want to play the same +sound multiple times at the same time, you need to initialize a separate `ma_sound` object. + +For the most flexibility when initializing sounds, use `ma_sound_init_ex()`. This uses miniaudio's +standard config/init pattern: + + ```c + ma_sound sound; + ma_sound_config soundConfig; + + soundConfig = ma_sound_config_init(); + soundConfig.pFilePath = NULL; // Set this to load from a file path. + soundConfig.pDataSource = NULL; // Set this to initialize from an existing data source. + soundConfig.pInitialAttachment = &someNodeInTheNodeGraph; + soundConfig.initialAttachmentInputBusIndex = 0; + soundConfig.channelsIn = 1; + soundConfig.channelsOut = 0; // Set to 0 to use the engine's native channel count. + + result = ma_sound_init_ex(&soundConfig, &sound); + if (result != MA_SUCCESS) { + return result; + } + ``` + +In the example above, the sound is being initialized without a file nor a data source. This is +valid, in which case the sound acts as a node in the middle of the node graph. This means you can +connect other sounds to this sound and allow it to act like a sound group. Indeed, this is exactly +what a `ma_sound_group` is. + +When loading a sound, you specify a set of flags that control how the sound is loaded and what +features are enabled for that sound. When no flags are set, the sound will be fully loaded into +memory in exactly the same format as how it's stored on the file system. The resource manager will +allocate a block of memory and then load the file directly into it. When reading audio data, it +will be decoded dynamically on the fly. In order to save processing time on the audio thread, it +might be beneficial to pre-decode the sound. You can do this with the `MA_SOUND_FLAG_DECODE` flag: + + ```c + ma_sound_init_from_file(&engine, "my_sound.wav", MA_SOUND_FLAG_DECODE, pGroup, NULL, &sound); + ``` + +By default, sounds will be loaded synchronously, meaning `ma_sound_init_*()` will not return until +the sound has been fully loaded. If this is prohibitive you can instead load sounds asynchronously +by specifying the `MA_SOUND_FLAG_ASYNC` flag: + + ```c + ma_sound_init_from_file(&engine, "my_sound.wav", MA_SOUND_FLAG_DECODE | MA_SOUND_FLAG_ASYNC, pGroup, NULL, &sound); + ``` + +This will result in `ma_sound_init_*()` returning quickly, but the sound won't yet have been fully +loaded. When you start the sound, it won't output anything until some sound is available. The sound +will start outputting audio before the sound has been fully decoded when the `MA_SOUND_FLAG_DECODE` +is specified. + +If you need to wait for an asynchronously loaded sound to be fully loaded, you can use a fence. A +fence in miniaudio is a simple synchronization mechanism which simply blocks until it's internal +counter hit's zero. You can specify a fence like so: + + ```c + ma_result result; + ma_fence fence; + ma_sound sounds[4]; + + result = ma_fence_init(&fence); + if (result != MA_SUCCESS) { + return result; + } + + // Load some sounds asynchronously. + for (int iSound = 0; iSound < 4; iSound += 1) { + ma_sound_init_from_file(&engine, mySoundFilesPaths[iSound], MA_SOUND_FLAG_DECODE | MA_SOUND_FLAG_ASYNC, pGroup, &fence, &sounds[iSound]); + } + + // ... do some other stuff here in the mean time ... + + // Wait for all sounds to finish loading. + ma_fence_wait(&fence); + ``` + +If loading the entire sound into memory is prohibitive, you can also configure the engine to stream +the audio data: + + ```c + ma_sound_init_from_file(&engine, "my_sound.wav", MA_SOUND_FLAG_STREAM, pGroup, NULL, &sound); + ``` + +When streaming sounds, 2 seconds worth of audio data is stored in memory. Although it should work +fine, it's inefficient to use streaming for short sounds. Streaming is useful for things like music +tracks in games. + +When loading a sound from a file path, the engine will reference count the file to prevent it from +being loaded if it's already in memory. When you uninitialize a sound, the reference count will be +decremented, and if it hits zero, the sound will be unloaded from memory. This reference counting +system is not used for streams. The engine will use a 64-bit hash of the file name when comparing +file paths which means there's a small chance you might encounter a name collision. If this is an +issue, you'll need to use a different name for one of the colliding file paths, or just not load +from files and instead load from a data source. + +You can use `ma_sound_init_copy()` to initialize a copy of another sound. Note, however, that this +only works for sounds that were initialized with `ma_sound_init_from_file()` and without the +`MA_SOUND_FLAG_STREAM` flag. + +When you initialize a sound, if you specify a sound group the sound will be attached to that group +automatically. If you set it to NULL, it will be automatically attached to the engine's endpoint. +If you would instead rather leave the sound unattached by default, you can specify the +`MA_SOUND_FLAG_NO_DEFAULT_ATTACHMENT` flag. This is useful if you want to set up a complex node +graph. + +Sounds are not started by default. To start a sound, use `ma_sound_start()`. Stop a sound with +`ma_sound_stop()`. + +Sounds can have their volume controlled with `ma_sound_set_volume()` in the same way as the +engine's master volume. + +Sounds support stereo panning and pitching. Set the pan with `ma_sound_set_pan()`. Setting the pan +to 0 will result in an unpanned sound. Setting it to -1 will shift everything to the left, whereas ++1 will shift it to the right. The pitch can be controlled with `ma_sound_set_pitch()`. A larger +value will result in a higher pitch. The pitch must be greater than 0. + +The engine supports 3D spatialization of sounds. By default sounds will have spatialization +enabled, but if a sound does not need to be spatialized it's best to disable it. There are two ways +to disable spatialization of a sound: + + ```c + // Disable spatialization at initialization time via a flag: + ma_sound_init_from_file(&engine, "my_sound.wav", MA_SOUND_FLAG_NO_SPATIALIZATION, NULL, NULL, &sound); + + // Dynamically disable or enable spatialization post-initialization: + ma_sound_set_spatialization_enabled(&sound, isSpatializationEnabled); + ``` + +By default sounds will be spatialized based on the closest listener. If a sound should always be +spatialized relative to a specific listener it can be pinned to one: + + ```c + ma_sound_set_pinned_listener_index(&sound, listenerIndex); + ``` + +Like listeners, sounds have a position. By default, the position of a sound is in absolute space, +but it can be changed to be relative to a listener: + + ```c + ma_sound_set_positioning(&sound, ma_positioning_relative); + ``` + +Note that relative positioning of a sound only makes sense if there is either only one listener, or +the sound is pinned to a specific listener. To set the position of a sound: + + ```c + ma_sound_set_position(&sound, posX, posY, posZ); + ``` + +The direction works the same way as a listener and represents the sound's forward direction: + + ```c + ma_sound_set_direction(&sound, forwardX, forwardY, forwardZ); + ``` + +Sound's also have a cone for controlling directional attenuation. This works exactly the same as +listeners: + + ```c + ma_sound_set_cone(&sound, innerAngleInRadians, outerAngleInRadians, outerGain); + ``` + +The velocity of a sound is used for doppler effect and can be set as such: + + ```c + ma_sound_set_velocity(&sound, velocityX, velocityY, velocityZ); + ``` + +The engine supports different attenuation models which can be configured on a per-sound basis. By +default the attenuation model is set to `ma_attenuation_model_inverse` which is the equivalent to +OpenAL's `AL_INVERSE_DISTANCE_CLAMPED`. Configure the attenuation model like so: + + ```c + ma_sound_set_attenuation_model(&sound, ma_attenuation_model_inverse); + ``` + +The supported attenuation models include the following: + + +----------------------------------+----------------------------------------------+ + | ma_attenuation_model_none | No distance attenuation. | + +----------------------------------+----------------------------------------------+ + | ma_attenuation_model_inverse | Equivalent to `AL_INVERSE_DISTANCE_CLAMPED`. | + +----------------------------------+----------------------------------------------+ + | ma_attenuation_model_linear | Linear attenuation. | + +----------------------------------+----------------------------------------------+ + | ma_attenuation_model_exponential | Exponential attenuation. | + +----------------------------------+----------------------------------------------+ + +To control how quickly a sound rolls off as it moves away from the listener, you need to configure +the rolloff: + + ```c + ma_sound_set_rolloff(&sound, rolloff); + ``` + +You can control the minimum and maximum gain to apply from spatialization: + + ```c + ma_sound_set_min_gain(&sound, minGain); + ma_sound_set_max_gain(&sound, maxGain); + ``` + +Likewise, in the calculation of attenuation, you can control the minimum and maximum distances for +the attenuation calculation. This is useful if you want to ensure sounds don't drop below a certain +volume after the listener moves further away and to have sounds play a maximum volume when the +listener is within a certain distance: + + ```c + ma_sound_set_min_distance(&sound, minDistance); + ma_sound_set_max_distance(&sound, maxDistance); + ``` + +The engine's spatialization system supports doppler effect. The doppler factor can be configure on +a per-sound basis like so: + + ```c + ma_sound_set_doppler_factor(&sound, dopplerFactor); + ``` + +You can fade sounds in and out with `ma_sound_set_fade_in_pcm_frames()` and +`ma_sound_set_fade_in_milliseconds()`. Set the volume to -1 to use the current volume as the +starting volume: + + ```c + // Fade in over 1 second. + ma_sound_set_fade_in_milliseconds(&sound, 0, 1, 1000); + + // ... sometime later ... + + // Fade out over 1 second, starting from the current volume. + ma_sound_set_fade_in_milliseconds(&sound, -1, 0, 1000); + ``` + +By default sounds will start immediately, but sometimes for timing and synchronization purposes it +can be useful to schedule a sound to start or stop: + + ```c + // Start the sound in 1 second from now. + ma_sound_set_start_time_in_pcm_frames(&sound, ma_engine_get_time_in_pcm_frames(&engine) + (ma_engine_get_sample_rate(&engine) * 1)); + + // Stop the sound in 2 seconds from now. + ma_sound_set_stop_time_in_pcm_frames(&sound, ma_engine_get_time_in_pcm_frames(&engine) + (ma_engine_get_sample_rate(&engine) * 2)); + ``` + +Note that scheduling a start time still requires an explicit call to `ma_sound_start()` before +anything will play. + +The time is specified in global time which is controlled by the engine. You can get the engine's +current time with `ma_engine_get_time_in_pcm_frames()`. The engine's global time is incremented +automatically as audio data is read, but it can be reset with `ma_engine_set_time_in_pcm_frames()` +in case it needs to be resynchronized for some reason. + +To determine whether or not a sound is currently playing, use `ma_sound_is_playing()`. This will +take the scheduled start and stop times into account. + +Whether or not a sound should loop can be controlled with `ma_sound_set_looping()`. Sounds will not +be looping by default. Use `ma_sound_is_looping()` to determine whether or not a sound is looping. + +Use `ma_sound_at_end()` to determine whether or not a sound is currently at the end. For a looping +sound this should never return true. Alternatively, you can configure a callback that will be fired +when the sound reaches the end. Note that the callback is fired from the audio thread which means +you cannot be uninitializing sound from the callback. To set the callback you can use +`ma_sound_set_end_callback()`. Alternatively, if you're using `ma_sound_init_ex()`, you can pass it +into the config like so: + + ```c + soundConfig.endCallback = my_end_callback; + soundConfig.pEndCallbackUserData = pMyEndCallbackUserData; + ``` + +The end callback is declared like so: + + ```c + void my_end_callback(void* pUserData, ma_sound* pSound) + { + ... + } + ``` + +Internally a sound wraps around a data source. Some APIs exist to control the underlying data +source, mainly for convenience: + + ```c + ma_sound_seek_to_pcm_frame(&sound, frameIndex); + ma_sound_get_data_format(&sound, &format, &channels, &sampleRate, pChannelMap, channelMapCapacity); + ma_sound_get_cursor_in_pcm_frames(&sound, &cursor); + ma_sound_get_length_in_pcm_frames(&sound, &length); + ``` + +Sound groups have the same API as sounds, only they are called `ma_sound_group`, and since they do +not have any notion of a data source, anything relating to a data source is unavailable. + +Internally, sound data is loaded via the `ma_decoder` API which means by default it only supports +file formats that have built-in support in miniaudio. You can extend this to support any kind of +file format through the use of custom decoders. To do this you'll need to use a self-managed +resource manager and configure it appropriately. See the "Resource Management" section below for +details on how to set this up. + + +6. Resource Management +====================== +Many programs will want to manage sound resources for things such as reference counting and +streaming. This is supported by miniaudio via the `ma_resource_manager` API. + +The resource manager is mainly responsible for the following: + + * Loading of sound files into memory with reference counting. + * Streaming of sound data. + +When loading a sound file, the resource manager will give you back a `ma_data_source` compatible +object called `ma_resource_manager_data_source`. This object can be passed into any +`ma_data_source` API which is how you can read and seek audio data. When loading a sound file, you +specify whether or not you want the sound to be fully loaded into memory (and optionally +pre-decoded) or streamed. When loading into memory, you can also specify whether or not you want +the data to be loaded asynchronously. + +The example below is how you can initialize a resource manager using it's default configuration: + + ```c + ma_resource_manager_config config; + ma_resource_manager resourceManager; + + config = ma_resource_manager_config_init(); + result = ma_resource_manager_init(&config, &resourceManager); + if (result != MA_SUCCESS) { + ma_device_uninit(&device); + printf("Failed to initialize the resource manager."); + return -1; + } + ``` + +You can configure the format, channels and sample rate of the decoded audio data. By default it +will use the file's native data format, but you can configure it to use a consistent format. This +is useful for offloading the cost of data conversion to load time rather than dynamically +converting at mixing time. To do this, you configure the decoded format, channels and sample rate +like the code below: + + ```c + config = ma_resource_manager_config_init(); + config.decodedFormat = device.playback.format; + config.decodedChannels = device.playback.channels; + config.decodedSampleRate = device.sampleRate; + ``` + +In the code above, the resource manager will be configured so that any decoded audio data will be +pre-converted at load time to the device's native data format. If instead you used defaults and +the data format of the file did not match the device's data format, you would need to convert the +data at mixing time which may be prohibitive in high-performance and large scale scenarios like +games. + +Internally the resource manager uses the `ma_decoder` API to load sounds. This means by default it +only supports decoders that are built into miniaudio. It's possible to support additional encoding +formats through the use of custom decoders. To do so, pass in your `ma_decoding_backend_vtable` +vtables into the resource manager config: + + ```c + ma_decoding_backend_vtable* pCustomBackendVTables[] = + { + &g_ma_decoding_backend_vtable_libvorbis, + &g_ma_decoding_backend_vtable_libopus + }; + + ... + + resourceManagerConfig.ppCustomDecodingBackendVTables = pCustomBackendVTables; + resourceManagerConfig.customDecodingBackendCount = sizeof(pCustomBackendVTables) / sizeof(pCustomBackendVTables[0]); + resourceManagerConfig.pCustomDecodingBackendUserData = NULL; + ``` + +This system can allow you to support any kind of file format. See the "Decoding" section for +details on how to implement custom decoders. The miniaudio repository includes examples for Opus +via libopus and libopusfile and Vorbis via libvorbis and libvorbisfile. + +Asynchronicity is achieved via a job system. When an operation needs to be performed, such as the +decoding of a page, a job will be posted to a queue which will then be processed by a job thread. +By default there will be only one job thread running, but this can be configured, like so: + + ```c + config = ma_resource_manager_config_init(); + config.jobThreadCount = MY_JOB_THREAD_COUNT; + ``` + +By default job threads are managed internally by the resource manager, however you can also self +manage your job threads if, for example, you want to integrate the job processing into your +existing job infrastructure, or if you simply don't like the way the resource manager does it. To +do this, just set the job thread count to 0 and process jobs manually. To process jobs, you first +need to retrieve a job using `ma_resource_manager_next_job()` and then process it using +`ma_job_process()`: + + ```c + config = ma_resource_manager_config_init(); + config.jobThreadCount = 0; // Don't manage any job threads internally. + config.flags = MA_RESOURCE_MANAGER_FLAG_NON_BLOCKING; // Optional. Makes `ma_resource_manager_next_job()` non-blocking. + + // ... Initialize your custom job threads ... + + void my_custom_job_thread(...) + { + for (;;) { + ma_job job; + ma_result result = ma_resource_manager_next_job(pMyResourceManager, &job); + if (result != MA_SUCCESS) { + if (result == MA_NO_DATA_AVAILABLE) { + // No jobs are available. Keep going. Will only get this if the resource manager was initialized + // with MA_RESOURCE_MANAGER_FLAG_NON_BLOCKING. + continue; + } else if (result == MA_CANCELLED) { + // MA_JOB_TYPE_QUIT was posted. Exit. + break; + } else { + // Some other error occurred. + break; + } + } + + ma_job_process(&job); + } + } + ``` + +In the example above, the `MA_JOB_TYPE_QUIT` event is the used as the termination +indicator, but you can use whatever you would like to terminate the thread. The call to +`ma_resource_manager_next_job()` is blocking by default, but can be configured to be non-blocking +by initializing the resource manager with the `MA_RESOURCE_MANAGER_FLAG_NON_BLOCKING` configuration +flag. Note that the `MA_JOB_TYPE_QUIT` will never be removed from the job queue. This +is to give every thread the opportunity to catch the event and terminate naturally. + +When loading a file, it's sometimes convenient to be able to customize how files are opened and +read instead of using standard `fopen()`, `fclose()`, etc. which is what miniaudio will use by +default. This can be done by setting `pVFS` member of the resource manager's config: + + ```c + // Initialize your custom VFS object. See documentation for VFS for information on how to do this. + my_custom_vfs vfs = my_custom_vfs_init(); + + config = ma_resource_manager_config_init(); + config.pVFS = &vfs; + ``` + +This is particularly useful in programs like games where you want to read straight from an archive +rather than the normal file system. If you do not specify a custom VFS, the resource manager will +use the operating system's normal file operations. + +To load a sound file and create a data source, call `ma_resource_manager_data_source_init()`. When +loading a sound you need to specify the file path and options for how the sounds should be loaded. +By default a sound will be loaded synchronously. The returned data source is owned by the caller +which means the caller is responsible for the allocation and freeing of the data source. Below is +an example for initializing a data source: + + ```c + ma_resource_manager_data_source dataSource; + ma_result result = ma_resource_manager_data_source_init(pResourceManager, pFilePath, flags, &dataSource); + if (result != MA_SUCCESS) { + // Error. + } + + // ... + + // A ma_resource_manager_data_source object is compatible with the `ma_data_source` API. To read data, just call + // the `ma_data_source_read_pcm_frames()` like you would with any normal data source. + result = ma_data_source_read_pcm_frames(&dataSource, pDecodedData, frameCount, &framesRead); + if (result != MA_SUCCESS) { + // Failed to read PCM frames. + } + + // ... + + ma_resource_manager_data_source_uninit(&dataSource); + ``` + +The `flags` parameter specifies how you want to perform loading of the sound file. It can be a +combination of the following flags: + + ``` + MA_RESOURCE_MANAGER_DATA_SOURCE_FLAG_STREAM + MA_RESOURCE_MANAGER_DATA_SOURCE_FLAG_DECODE + MA_RESOURCE_MANAGER_DATA_SOURCE_FLAG_ASYNC + MA_RESOURCE_MANAGER_DATA_SOURCE_FLAG_WAIT_INIT + MA_RESOURCE_MANAGER_DATA_SOURCE_FLAG_LOOPING + ``` + +When no flags are specified (set to 0), the sound will be fully loaded into memory, but not +decoded, meaning the raw file data will be stored in memory, and then dynamically decoded when +`ma_data_source_read_pcm_frames()` is called. To instead decode the audio data before storing it in +memory, use the `MA_RESOURCE_MANAGER_DATA_SOURCE_FLAG_DECODE` flag. By default, the sound file will +be loaded synchronously, meaning `ma_resource_manager_data_source_init()` will only return after +the entire file has been loaded. This is good for simplicity, but can be prohibitively slow. You +can instead load the sound asynchronously using the `MA_RESOURCE_MANAGER_DATA_SOURCE_ASYNC` flag. +This will result in `ma_resource_manager_data_source_init()` returning quickly, but no data will be +returned by `ma_data_source_read_pcm_frames()` until some data is available. When no data is +available because the asynchronous decoding hasn't caught up, `MA_BUSY` will be returned by +`ma_data_source_read_pcm_frames()`. + +For large sounds, it's often prohibitive to store the entire file in memory. To mitigate this, you +can instead stream audio data which you can do by specifying the +`MA_RESOURCE_MANAGER_DATA_SOURCE_FLAG_STREAM` flag. When streaming, data will be decoded in 1 +second pages. When a new page needs to be decoded, a job will be posted to the job queue and then +subsequently processed in a job thread. + +The `MA_RESOURCE_MANAGER_DATA_SOURCE_FLAG_LOOPING` flag can be used so that the sound will loop +when it reaches the end by default. It's recommended you use this flag when you want to have a +looping streaming sound. If you try loading a very short sound as a stream, you will get a glitch. +This is because the resource manager needs to pre-fill the initial buffer at initialization time, +and if you don't specify the `MA_RESOURCE_MANAGER_DATA_SOURCE_FLAG_LOOPING` flag, the resource +manager will assume the sound is not looping and will stop filling the buffer when it reaches the +end, therefore resulting in a discontinuous buffer. + +For in-memory sounds, reference counting is used to ensure the data is loaded only once. This means +multiple calls to `ma_resource_manager_data_source_init()` with the same file path will result in +the file data only being loaded once. Each call to `ma_resource_manager_data_source_init()` must be +matched up with a call to `ma_resource_manager_data_source_uninit()`. Sometimes it can be useful +for a program to register self-managed raw audio data and associate it with a file path. Use the +`ma_resource_manager_register_*()` and `ma_resource_manager_unregister_*()` APIs to do this. +`ma_resource_manager_register_decoded_data()` is used to associate a pointer to raw, self-managed +decoded audio data in the specified data format with the specified name. Likewise, +`ma_resource_manager_register_encoded_data()` is used to associate a pointer to raw self-managed +encoded audio data (the raw file data) with the specified name. Note that these names need not be +actual file paths. When `ma_resource_manager_data_source_init()` is called (without the +`MA_RESOURCE_MANAGER_DATA_SOURCE_FLAG_STREAM` flag), the resource manager will look for these +explicitly registered data buffers and, if found, will use it as the backing data for the data +source. Note that the resource manager does *not* make a copy of this data so it is up to the +caller to ensure the pointer stays valid for its lifetime. Use +`ma_resource_manager_unregister_data()` to unregister the self-managed data. You can also use +`ma_resource_manager_register_file()` and `ma_resource_manager_unregister_file()` to register and +unregister a file. It does not make sense to use the `MA_RESOURCE_MANAGER_DATA_SOURCE_FLAG_STREAM` +flag with a self-managed data pointer. + + +6.1. Asynchronous Loading and Synchronization +--------------------------------------------- +When loading asynchronously, it can be useful to poll whether or not loading has finished. Use +`ma_resource_manager_data_source_result()` to determine this. For in-memory sounds, this will +return `MA_SUCCESS` when the file has been *entirely* decoded. If the sound is still being decoded, +`MA_BUSY` will be returned. Otherwise, some other error code will be returned if the sound failed +to load. For streaming data sources, `MA_SUCCESS` will be returned when the first page has been +decoded and the sound is ready to be played. If the first page is still being decoded, `MA_BUSY` +will be returned. Otherwise, some other error code will be returned if the sound failed to load. + +In addition to polling, you can also use a simple synchronization object called a "fence" to wait +for asynchronously loaded sounds to finish. This is called `ma_fence`. The advantage to using a +fence is that it can be used to wait for a group of sounds to finish loading rather than waiting +for sounds on an individual basis. There are two stages to loading a sound: + + * Initialization of the internal decoder; and + * Completion of decoding of the file (the file is fully decoded) + +You can specify separate fences for each of the different stages. Waiting for the initialization +of the internal decoder is important for when you need to know the sample format, channels and +sample rate of the file. + +The example below shows how you could use a fence when loading a number of sounds: + + ```c + // This fence will be released when all sounds are finished loading entirely. + ma_fence fence; + ma_fence_init(&fence); + + // This will be passed into the initialization routine for each sound. + ma_resource_manager_pipeline_notifications notifications = ma_resource_manager_pipeline_notifications_init(); + notifications.done.pFence = &fence; + + // Now load a bunch of sounds: + for (iSound = 0; iSound < soundCount; iSound += 1) { + ma_resource_manager_data_source_init(pResourceManager, pSoundFilePaths[iSound], flags, ¬ifications, &pSoundSources[iSound]); + } + + // ... DO SOMETHING ELSE WHILE SOUNDS ARE LOADING ... + + // Wait for loading of sounds to finish. + ma_fence_wait(&fence); + ``` + +In the example above we used a fence for waiting until the entire file has been fully decoded. If +you only need to wait for the initialization of the internal decoder to complete, you can use the +`init` member of the `ma_resource_manager_pipeline_notifications` object: + + ```c + notifications.init.pFence = &fence; + ``` + +If a fence is not appropriate for your situation, you can instead use a callback that is fired on +an individual sound basis. This is done in a very similar way to fences: + + ```c + typedef struct + { + ma_async_notification_callbacks cb; + void* pMyData; + } my_notification; + + void my_notification_callback(ma_async_notification* pNotification) + { + my_notification* pMyNotification = (my_notification*)pNotification; + + // Do something in response to the sound finishing loading. + } + + ... + + my_notification myCallback; + myCallback.cb.onSignal = my_notification_callback; + myCallback.pMyData = pMyData; + + ma_resource_manager_pipeline_notifications notifications = ma_resource_manager_pipeline_notifications_init(); + notifications.done.pNotification = &myCallback; + + ma_resource_manager_data_source_init(pResourceManager, "my_sound.wav", flags, ¬ifications, &mySound); + ``` + +In the example above we just extend the `ma_async_notification_callbacks` object and pass an +instantiation into the `ma_resource_manager_pipeline_notifications` in the same way as we did with +the fence, only we set `pNotification` instead of `pFence`. You can set both of these at the same +time and they should both work as expected. If using the `pNotification` system, you need to ensure +your `ma_async_notification_callbacks` object stays valid. + + + +6.2. Resource Manager Implementation Details +-------------------------------------------- +Resources are managed in two main ways: + + * By storing the entire sound inside an in-memory buffer (referred to as a data buffer) + * By streaming audio data on the fly (referred to as a data stream) + +A resource managed data source (`ma_resource_manager_data_source`) encapsulates a data buffer or +data stream, depending on whether or not the data source was initialized with the +`MA_RESOURCE_MANAGER_DATA_SOURCE_FLAG_STREAM` flag. If so, it will make use of a +`ma_resource_manager_data_stream` object. Otherwise it will use a `ma_resource_manager_data_buffer` +object. Both of these objects are data sources which means they can be used with any +`ma_data_source_*()` API. + +Another major feature of the resource manager is the ability to asynchronously decode audio files. +This relieves the audio thread of time-consuming decoding which can negatively affect scalability +due to the audio thread needing to complete it's work extremely quickly to avoid glitching. +Asynchronous decoding is achieved through a job system. There is a central multi-producer, +multi-consumer, fixed-capacity job queue. When some asynchronous work needs to be done, a job is +posted to the queue which is then read by a job thread. The number of job threads can be +configured for improved scalability, and job threads can all run in parallel without needing to +worry about the order of execution (how this is achieved is explained below). + +When a sound is being loaded asynchronously, playback can begin before the sound has been fully +decoded. This enables the application to start playback of the sound quickly, while at the same +time allowing to resource manager to keep loading in the background. Since there may be less +threads than the number of sounds being loaded at a given time, a simple scheduling system is used +to keep decoding time balanced and fair. The resource manager solves this by splitting decoding +into chunks called pages. By default, each page is 1 second long. When a page has been decoded, a +new job will be posted to start decoding the next page. By dividing up decoding into pages, an +individual sound shouldn't ever delay every other sound from having their first page decoded. Of +course, when loading many sounds at the same time, there will always be an amount of time required +to process jobs in the queue so in heavy load situations there will still be some delay. To +determine if a data source is ready to have some frames read, use +`ma_resource_manager_data_source_get_available_frames()`. This will return the number of frames +available starting from the current position. + + +6.2.1. Job Queue +---------------- +The resource manager uses a job queue which is multi-producer, multi-consumer, and fixed-capacity. +This job queue is not currently lock-free, and instead uses a spinlock to achieve thread-safety. +Only a fixed number of jobs can be allocated and inserted into the queue which is done through a +lock-free data structure for allocating an index into a fixed sized array, with reference counting +for mitigation of the ABA problem. The reference count is 32-bit. + +For many types of jobs it's important that they execute in a specific order. In these cases, jobs +are executed serially. For the resource manager, serial execution of jobs is only required on a +per-object basis (per data buffer or per data stream). Each of these objects stores an execution +counter. When a job is posted it is associated with an execution counter. When the job is +processed, it checks if the execution counter of the job equals the execution counter of the +owning object and if so, processes the job. If the counters are not equal, the job will be posted +back onto the job queue for later processing. When the job finishes processing the execution order +of the main object is incremented. This system means the no matter how many job threads are +executing, decoding of an individual sound will always get processed serially. The advantage to +having multiple threads comes into play when loading multiple sounds at the same time. + +The resource manager's job queue is not 100% lock-free and will use a spinlock to achieve +thread-safety for a very small section of code. This is only relevant when the resource manager +uses more than one job thread. If only using a single job thread, which is the default, the +lock should never actually wait in practice. The amount of time spent locking should be quite +short, but it's something to be aware of for those who have pedantic lock-free requirements and +need to use more than one job thread. There are plans to remove this lock in a future version. + +In addition, posting a job will release a semaphore, which on Win32 is implemented with +`ReleaseSemaphore` and on POSIX platforms via a condition variable: + + ```c + pthread_mutex_lock(&pSemaphore->lock); + { + pSemaphore->value += 1; + pthread_cond_signal(&pSemaphore->cond); + } + pthread_mutex_unlock(&pSemaphore->lock); + ``` + +Again, this is relevant for those with strict lock-free requirements in the audio thread. To avoid +this, you can use non-blocking mode (via the `MA_JOB_QUEUE_FLAG_NON_BLOCKING` +flag) and implement your own job processing routine (see the "Resource Manager" section above for +details on how to do this). + + + +6.2.2. Data Buffers +------------------- +When the `MA_RESOURCE_MANAGER_DATA_SOURCE_FLAG_STREAM` flag is excluded at initialization time, the +resource manager will try to load the data into an in-memory data buffer. Before doing so, however, +it will first check if the specified file is already loaded. If so, it will increment a reference +counter and just use the already loaded data. This saves both time and memory. When the data buffer +is uninitialized, the reference counter will be decremented. If the counter hits zero, the file +will be unloaded. This is a detail to keep in mind because it could result in excessive loading and +unloading of a sound. For example, the following sequence will result in a file be loaded twice, +once after the other: + + ```c + ma_resource_manager_data_source_init(pResourceManager, "my_file", ..., &myDataBuffer0); // Refcount = 1. Initial load. + ma_resource_manager_data_source_uninit(&myDataBuffer0); // Refcount = 0. Unloaded. + + ma_resource_manager_data_source_init(pResourceManager, "my_file", ..., &myDataBuffer1); // Refcount = 1. Reloaded because previous uninit() unloaded it. + ma_resource_manager_data_source_uninit(&myDataBuffer1); // Refcount = 0. Unloaded. + ``` + +A binary search tree (BST) is used for storing data buffers as it has good balance between +efficiency and simplicity. The key of the BST is a 64-bit hash of the file path that was passed +into `ma_resource_manager_data_source_init()`. The advantage of using a hash is that it saves +memory over storing the entire path, has faster comparisons, and results in a mostly balanced BST +due to the random nature of the hash. The disadvantages are that file names are case-sensitive and +there's a small chance of name collisions. If case-sensitivity is an issue, you should normalize +your file names to upper- or lower-case before initializing your data sources. If name collisions +become an issue, you'll need to change the name of one of the colliding names or just not use the +resource manager. + +When a sound file has not already been loaded and the `MA_RESOURCE_MANAGER_DATA_SOURCE_FLAG_ASYNC` +flag is excluded, the file will be decoded synchronously by the calling thread. There are two +options for controlling how the audio is stored in the data buffer - encoded or decoded. When the +`MA_RESOURCE_MANAGER_DATA_SOURCE_FLAG_DECODE` option is excluded, the raw file data will be stored +in memory. Otherwise the sound will be decoded before storing it in memory. Synchronous loading is +a very simple and standard process of simply adding an item to the BST, allocating a block of +memory and then decoding (if `MA_RESOURCE_MANAGER_DATA_SOURCE_FLAG_DECODE` is specified). + +When the `MA_RESOURCE_MANAGER_DATA_SOURCE_FLAG_ASYNC` flag is specified, loading of the data buffer +is done asynchronously. In this case, a job is posted to the queue to start loading and then the +function immediately returns, setting an internal result code to `MA_BUSY`. This result code is +returned when the program calls `ma_resource_manager_data_source_result()`. When decoding has fully +completed `MA_SUCCESS` will be returned. This can be used to know if loading has fully completed. + +When loading asynchronously, a single job is posted to the queue of the type +`MA_JOB_TYPE_RESOURCE_MANAGER_LOAD_DATA_BUFFER_NODE`. This involves making a copy of the file path and +associating it with job. When the job is processed by the job thread, it will first load the file +using the VFS associated with the resource manager. When using a custom VFS, it's important that it +be completely thread-safe because it will be used from one or more job threads at the same time. +Individual files should only ever be accessed by one thread at a time, however. After opening the +file via the VFS, the job will determine whether or not the file is being decoded. If not, it +simply allocates a block of memory and loads the raw file contents into it and returns. On the +other hand, when the file is being decoded, it will first allocate a decoder on the heap and +initialize it. Then it will check if the length of the file is known. If so it will allocate a +block of memory to store the decoded output and initialize it to silence. If the size is unknown, +it will allocate room for one page. After memory has been allocated, the first page will be +decoded. If the sound is shorter than a page, the result code will be set to `MA_SUCCESS` and the +completion event will be signalled and loading is now complete. If, however, there is more to +decode, a job with the code `MA_JOB_TYPE_RESOURCE_MANAGER_PAGE_DATA_BUFFER_NODE` is posted. This job +will decode the next page and perform the same process if it reaches the end. If there is more to +decode, the job will post another `MA_JOB_TYPE_RESOURCE_MANAGER_PAGE_DATA_BUFFER_NODE` job which will +keep on happening until the sound has been fully decoded. For sounds of an unknown length, each +page will be linked together as a linked list. Internally this is implemented via the +`ma_paged_audio_buffer` object. + + +6.2.3. Data Streams +------------------- +Data streams only ever store two pages worth of data for each instance. They are most useful for +large sounds like music tracks in games that would consume too much memory if fully decoded in +memory. After every frame from a page has been read, a job will be posted to load the next page +which is done from the VFS. + +For data streams, the `MA_RESOURCE_MANAGER_DATA_SOURCE_FLAG_ASYNC` flag will determine whether or +not initialization of the data source waits until the two pages have been decoded. When unset, +`ma_resource_manager_data_source_init()` will wait until the two pages have been loaded, otherwise +it will return immediately. + +When frames are read from a data stream using `ma_resource_manager_data_source_read_pcm_frames()`, +`MA_BUSY` will be returned if there are no frames available. If there are some frames available, +but less than the number requested, `MA_SUCCESS` will be returned, but the actual number of frames +read will be less than the number requested. Due to the asynchronous nature of data streams, +seeking is also asynchronous. If the data stream is in the middle of a seek, `MA_BUSY` will be +returned when trying to read frames. + +When `ma_resource_manager_data_source_read_pcm_frames()` results in a page getting fully consumed +a job is posted to load the next page. This will be posted from the same thread that called +`ma_resource_manager_data_source_read_pcm_frames()`. + +Data streams are uninitialized by posting a job to the queue, but the function won't return until +that job has been processed. The reason for this is that the caller owns the data stream object and +therefore miniaudio needs to ensure everything completes before handing back control to the caller. +Also, if the data stream is uninitialized while pages are in the middle of decoding, they must +complete before destroying any underlying object and the job system handles this cleanly. + +Note that when a new page needs to be loaded, a job will be posted to the resource manager's job +thread from the audio thread. You must keep in mind the details mentioned in the "Job Queue" +section above regarding locking when posting an event if you require a strictly lock-free audio +thread. + + + +7. Node Graph +============= +miniaudio's routing infrastructure follows a node graph paradigm. The idea is that you create a +node whose outputs are attached to inputs of another node, thereby creating a graph. There are +different types of nodes, with each node in the graph processing input data to produce output, +which is then fed through the chain. Each node in the graph can apply their own custom effects. At +the start of the graph will usually be one or more data source nodes which have no inputs and +instead pull their data from a data source. At the end of the graph is an endpoint which represents +the end of the chain and is where the final output is ultimately extracted from. + +Each node has a number of input buses and a number of output buses. An output bus from a node is +attached to an input bus of another. Multiple nodes can connect their output buses to another +node's input bus, in which case their outputs will be mixed before processing by the node. Below is +a diagram that illustrates a hypothetical node graph setup: + + ``` + >>>>>>>>>>>>>>>>>>>>>>>>>>>>>> Data flows left to right >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> + + +---------------+ +-----------------+ + | Data Source 1 =----+ +----------+ +----= Low Pass Filter =----+ + +---------------+ | | =----+ +-----------------+ | +----------+ + +----= Splitter | +----= ENDPOINT | + +---------------+ | | =----+ +-----------------+ | +----------+ + | Data Source 2 =----+ +----------+ +----= Echo / Delay =----+ + +---------------+ +-----------------+ + ``` + +In the above graph, it starts with two data sources whose outputs are attached to the input of a +splitter node. It's at this point that the two data sources are mixed. After mixing, the splitter +performs it's processing routine and produces two outputs which is simply a duplication of the +input stream. One output is attached to a low pass filter, whereas the other output is attached to +a echo/delay. The outputs of the low pass filter and the echo are attached to the endpoint, and +since they're both connected to the same input bus, they'll be mixed. + +Each input bus must be configured to accept the same number of channels, but the number of channels +used by input buses can be different to the number of channels for output buses in which case +miniaudio will automatically convert the input data to the output channel count before processing. +The number of channels of an output bus of one node must match the channel count of the input bus +it's attached to. The channel counts cannot be changed after the node has been initialized. If you +attempt to attach an output bus to an input bus with a different channel count, attachment will +fail. + +To use a node graph, you first need to initialize a `ma_node_graph` object. This is essentially a +container around the entire graph. The `ma_node_graph` object is required for some thread-safety +issues which will be explained later. A `ma_node_graph` object is initialized using miniaudio's +standard config/init system: + + ```c + ma_node_graph_config nodeGraphConfig = ma_node_graph_config_init(myChannelCount); + + result = ma_node_graph_init(&nodeGraphConfig, NULL, &nodeGraph); // Second parameter is a pointer to allocation callbacks. + if (result != MA_SUCCESS) { + // Failed to initialize node graph. + } + ``` + +When you initialize the node graph, you're specifying the channel count of the endpoint. The +endpoint is a special node which has one input bus and one output bus, both of which have the +same channel count, which is specified in the config. Any nodes that connect directly to the +endpoint must be configured such that their output buses have the same channel count. When you read +audio data from the node graph, it'll have the channel count you specified in the config. To read +data from the graph: + + ```c + ma_uint32 framesRead; + result = ma_node_graph_read_pcm_frames(&nodeGraph, pFramesOut, frameCount, &framesRead); + if (result != MA_SUCCESS) { + // Failed to read data from the node graph. + } + ``` + +When you read audio data, miniaudio starts at the node graph's endpoint node which then pulls in +data from its input attachments, which in turn recursively pull in data from their inputs, and so +on. At the start of the graph there will be some kind of data source node which will have zero +inputs and will instead read directly from a data source. The base nodes don't literally need to +read from a `ma_data_source` object, but they will always have some kind of underlying object that +sources some kind of audio. The `ma_data_source_node` node can be used to read from a +`ma_data_source`. Data is always in floating-point format and in the number of channels you +specified when the graph was initialized. The sample rate is defined by the underlying data sources. +It's up to you to ensure they use a consistent and appropriate sample rate. + +The `ma_node` API is designed to allow custom nodes to be implemented with relative ease, but +miniaudio includes a few stock nodes for common functionality. This is how you would initialize a +node which reads directly from a data source (`ma_data_source_node`) which is an example of one +of the stock nodes that comes with miniaudio: + + ```c + ma_data_source_node_config config = ma_data_source_node_config_init(pMyDataSource); + + ma_data_source_node dataSourceNode; + result = ma_data_source_node_init(&nodeGraph, &config, NULL, &dataSourceNode); + if (result != MA_SUCCESS) { + // Failed to create data source node. + } + ``` + +The data source node will use the output channel count to determine the channel count of the output +bus. There will be 1 output bus and 0 input buses (data will be drawn directly from the data +source). The data source must output to floating-point (`ma_format_f32`) or else an error will be +returned from `ma_data_source_node_init()`. + +By default the node will not be attached to the graph. To do so, use `ma_node_attach_output_bus()`: + + ```c + result = ma_node_attach_output_bus(&dataSourceNode, 0, ma_node_graph_get_endpoint(&nodeGraph), 0); + if (result != MA_SUCCESS) { + // Failed to attach node. + } + ``` + +The code above connects the data source node directly to the endpoint. Since the data source node +has only a single output bus, the index will always be 0. Likewise, the endpoint only has a single +input bus which means the input bus index will also always be 0. + +To detach a specific output bus, use `ma_node_detach_output_bus()`. To detach all output buses, use +`ma_node_detach_all_output_buses()`. If you want to just move the output bus from one attachment to +another, you do not need to detach first. You can just call `ma_node_attach_output_bus()` and it'll +deal with it for you. + +Less frequently you may want to create a specialized node. This will be a node where you implement +your own processing callback to apply a custom effect of some kind. This is similar to initializing +one of the stock node types, only this time you need to specify a pointer to a vtable containing a +pointer to the processing function and the number of input and output buses. Example: + + ```c + static void my_custom_node_process_pcm_frames(ma_node* pNode, const float** ppFramesIn, ma_uint32* pFrameCountIn, float** ppFramesOut, ma_uint32* pFrameCountOut) + { + // Do some processing of ppFramesIn (one stream of audio data per input bus) + const float* pFramesIn_0 = ppFramesIn[0]; // Input bus @ index 0. + const float* pFramesIn_1 = ppFramesIn[1]; // Input bus @ index 1. + float* pFramesOut_0 = ppFramesOut[0]; // Output bus @ index 0. + + // Do some processing. On input, `pFrameCountIn` will be the number of input frames in each + // buffer in `ppFramesIn` and `pFrameCountOut` will be the capacity of each of the buffers + // in `ppFramesOut`. On output, `pFrameCountIn` should be set to the number of input frames + // your node consumed and `pFrameCountOut` should be set the number of output frames that + // were produced. + // + // You should process as many frames as you can. If your effect consumes input frames at the + // same rate as output frames (always the case, unless you're doing resampling), you need + // only look at `ppFramesOut` and process that exact number of frames. If you're doing + // resampling, you'll need to be sure to set both `pFrameCountIn` and `pFrameCountOut` + // properly. + } + + static ma_node_vtable my_custom_node_vtable = + { + my_custom_node_process_pcm_frames, // The function that will be called to process your custom node. This is where you'd implement your effect processing. + NULL, // Optional. A callback for calculating the number of input frames that are required to process a specified number of output frames. + 2, // 2 input buses. + 1, // 1 output bus. + 0 // Default flags. + }; + + ... + + // Each bus needs to have a channel count specified. To do this you need to specify the channel + // counts in an array and then pass that into the node config. + ma_uint32 inputChannels[2]; // Equal in size to the number of input channels specified in the vtable. + ma_uint32 outputChannels[1]; // Equal in size to the number of output channels specified in the vtable. + + inputChannels[0] = channelsIn; + inputChannels[1] = channelsIn; + outputChannels[0] = channelsOut; + + ma_node_config nodeConfig = ma_node_config_init(); + nodeConfig.vtable = &my_custom_node_vtable; + nodeConfig.pInputChannels = inputChannels; + nodeConfig.pOutputChannels = outputChannels; + + ma_node_base node; + result = ma_node_init(&nodeGraph, &nodeConfig, NULL, &node); + if (result != MA_SUCCESS) { + // Failed to initialize node. + } + ``` + +When initializing a custom node, as in the code above, you'll normally just place your vtable in +static space. The number of input and output buses are specified as part of the vtable. If you need +a variable number of buses on a per-node bases, the vtable should have the relevant bus count set +to `MA_NODE_BUS_COUNT_UNKNOWN`. In this case, the bus count should be set in the node config: + + ```c + static ma_node_vtable my_custom_node_vtable = + { + my_custom_node_process_pcm_frames, // The function that will be called process your custom node. This is where you'd implement your effect processing. + NULL, // Optional. A callback for calculating the number of input frames that are required to process a specified number of output frames. + MA_NODE_BUS_COUNT_UNKNOWN, // The number of input buses is determined on a per-node basis. + 1, // 1 output bus. + 0 // Default flags. + }; + + ... + + ma_node_config nodeConfig = ma_node_config_init(); + nodeConfig.vtable = &my_custom_node_vtable; + nodeConfig.inputBusCount = myBusCount; // <-- Since the vtable specifies MA_NODE_BUS_COUNT_UNKNOWN, the input bus count should be set here. + nodeConfig.pInputChannels = inputChannels; // <-- Make sure there are nodeConfig.inputBusCount elements in this array. + nodeConfig.pOutputChannels = outputChannels; // <-- The vtable specifies 1 output bus, so there must be 1 element in this array. + ``` + +In the above example it's important to never set the `inputBusCount` and `outputBusCount` members +to anything other than their defaults if the vtable specifies an explicit count. They can only be +set if the vtable specifies MA_NODE_BUS_COUNT_UNKNOWN in the relevant bus count. + +Most often you'll want to create a structure to encapsulate your node with some extra data. You +need to make sure the `ma_node_base` object is your first member of the structure: + + ```c + typedef struct + { + ma_node_base base; // <-- Make sure this is always the first member. + float someCustomData; + } my_custom_node; + ``` + +By doing this, your object will be compatible with all `ma_node` APIs and you can attach it to the +graph just like any other node. + +In the custom processing callback (`my_custom_node_process_pcm_frames()` in the example above), the +number of channels for each bus is what was specified by the config when the node was initialized +with `ma_node_init()`. In addition, all attachments to each of the input buses will have been +pre-mixed by miniaudio. The config allows you to specify different channel counts for each +individual input and output bus. It's up to the effect to handle it appropriate, and if it can't, +return an error in it's initialization routine. + +Custom nodes can be assigned some flags to describe their behaviour. These are set via the vtable +and include the following: + + +-----------------------------------------+---------------------------------------------------+ + | Flag Name | Description | + +-----------------------------------------+---------------------------------------------------+ + | MA_NODE_FLAG_PASSTHROUGH | Useful for nodes that do not do any kind of audio | + | | processing, but are instead used for tracking | + | | time, handling events, etc. Also used by the | + | | internal endpoint node. It reads directly from | + | | the input bus to the output bus. Nodes with this | + | | flag must have exactly 1 input bus and 1 output | + | | bus, and both buses must have the same channel | + | | counts. | + +-----------------------------------------+---------------------------------------------------+ + | MA_NODE_FLAG_CONTINUOUS_PROCESSING | Causes the processing callback to be called even | + | | when no data is available to be read from input | + | | attachments. When a node has at least one input | + | | bus, but there are no inputs attached or the | + | | inputs do not deliver any data, the node's | + | | processing callback will not get fired. This flag | + | | will make it so the callback is always fired | + | | regardless of whether or not any input data is | + | | received. This is useful for effects like | + | | echos where there will be a tail of audio data | + | | that still needs to be processed even when the | + | | original data sources have reached their ends. It | + | | may also be useful for nodes that must always | + | | have their processing callback fired when there | + | | are no inputs attached. | + +-----------------------------------------+---------------------------------------------------+ + | MA_NODE_FLAG_ALLOW_NULL_INPUT | Used in conjunction with | + | | `MA_NODE_FLAG_CONTINUOUS_PROCESSING`. When this | + | | is set, the `ppFramesIn` parameter of the | + | | processing callback will be set to NULL when | + | | there are no input frames are available. When | + | | this is unset, silence will be posted to the | + | | processing callback. | + +-----------------------------------------+---------------------------------------------------+ + | MA_NODE_FLAG_DIFFERENT_PROCESSING_RATES | Used to tell miniaudio that input and output | + | | frames are processed at different rates. You | + | | should set this for any nodes that perform | + | | resampling. | + +-----------------------------------------+---------------------------------------------------+ + | MA_NODE_FLAG_SILENT_OUTPUT | Used to tell miniaudio that a node produces only | + | | silent output. This is useful for nodes where you | + | | don't want the output to contribute to the final | + | | mix. An example might be if you want split your | + | | stream and have one branch be output to a file. | + | | When using this flag, you should avoid writing to | + | | the output buffer of the node's processing | + | | callback because miniaudio will ignore it anyway. | + +-----------------------------------------+---------------------------------------------------+ + + +If you need to make a copy of an audio stream for effect processing you can use a splitter node +called `ma_splitter_node`. This takes has 1 input bus and splits the stream into 2 output buses. +You can use it like this: + + ```c + ma_splitter_node_config splitterNodeConfig = ma_splitter_node_config_init(channels); + + ma_splitter_node splitterNode; + result = ma_splitter_node_init(&nodeGraph, &splitterNodeConfig, NULL, &splitterNode); + if (result != MA_SUCCESS) { + // Failed to create node. + } + + // Attach your output buses to two different input buses (can be on two different nodes). + ma_node_attach_output_bus(&splitterNode, 0, ma_node_graph_get_endpoint(&nodeGraph), 0); // Attach directly to the endpoint. + ma_node_attach_output_bus(&splitterNode, 1, &myEffectNode, 0); // Attach to input bus 0 of some effect node. + ``` + +The volume of an output bus can be configured on a per-bus basis: + + ```c + ma_node_set_output_bus_volume(&splitterNode, 0, 0.5f); + ma_node_set_output_bus_volume(&splitterNode, 1, 0.5f); + ``` + +In the code above we're using the splitter node from before and changing the volume of each of the +copied streams. + +You can start and stop a node with the following: + + ```c + ma_node_set_state(&splitterNode, ma_node_state_started); // The default state. + ma_node_set_state(&splitterNode, ma_node_state_stopped); + ``` + +By default the node is in a started state, but since it won't be connected to anything won't +actually be invoked by the node graph until it's connected. When you stop a node, data will not be +read from any of its input connections. You can use this property to stop a group of sounds +atomically. + +You can configure the initial state of a node in it's config: + + ```c + nodeConfig.initialState = ma_node_state_stopped; + ``` + +Note that for the stock specialized nodes, all of their configs will have a `nodeConfig` member +which is the config to use with the base node. This is where the initial state can be configured +for specialized nodes: + + ```c + dataSourceNodeConfig.nodeConfig.initialState = ma_node_state_stopped; + ``` + +When using a specialized node like `ma_data_source_node` or `ma_splitter_node`, be sure to not +modify the `vtable` member of the `nodeConfig` object. + + +7.1. Timing +----------- +The node graph supports starting and stopping nodes at scheduled times. This is especially useful +for data source nodes where you want to get the node set up, but only start playback at a specific +time. There are two clocks: local and global. + +A local clock is per-node, whereas the global clock is per graph. Scheduling starts and stops can +only be done based on the global clock because the local clock will not be running while the node +is stopped. The global clocks advances whenever `ma_node_graph_read_pcm_frames()` is called. On the +other hand, the local clock only advances when the node's processing callback is fired, and is +advanced based on the output frame count. + +To retrieve the global time, use `ma_node_graph_get_time()`. The global time can be set with +`ma_node_graph_set_time()` which might be useful if you want to do seeking on a global timeline. +Getting and setting the local time is similar. Use `ma_node_get_time()` to retrieve the local time, +and `ma_node_set_time()` to set the local time. The global and local times will be advanced by the +audio thread, so care should be taken to avoid data races. Ideally you should avoid calling these +outside of the node processing callbacks which are always run on the audio thread. + +There is basic support for scheduling the starting and stopping of nodes. You can only schedule one +start and one stop at a time. This is mainly intended for putting nodes into a started or stopped +state in a frame-exact manner. Without this mechanism, starting and stopping of a node is limited +to the resolution of a call to `ma_node_graph_read_pcm_frames()` which would typically be in blocks +of several milliseconds. The following APIs can be used for scheduling node states: + + ```c + ma_node_set_state_time() + ma_node_get_state_time() + ``` + +The time is absolute and must be based on the global clock. An example is below: + + ```c + ma_node_set_state_time(&myNode, ma_node_state_started, sampleRate*1); // Delay starting to 1 second. + ma_node_set_state_time(&myNode, ma_node_state_stopped, sampleRate*5); // Delay stopping to 5 seconds. + ``` + +An example for changing the state using a relative time. + + ```c + ma_node_set_state_time(&myNode, ma_node_state_started, sampleRate*1 + ma_node_graph_get_time(&myNodeGraph)); + ma_node_set_state_time(&myNode, ma_node_state_stopped, sampleRate*5 + ma_node_graph_get_time(&myNodeGraph)); + ``` + +Note that due to the nature of multi-threading the times may not be 100% exact. If this is an +issue, consider scheduling state changes from within a processing callback. An idea might be to +have some kind of passthrough trigger node that is used specifically for tracking time and handling +events. + + + +7.2. Thread Safety and Locking +------------------------------ +When processing audio, it's ideal not to have any kind of locking in the audio thread. Since it's +expected that `ma_node_graph_read_pcm_frames()` would be run on the audio thread, it does so +without the use of any locks. This section discusses the implementation used by miniaudio and goes +over some of the compromises employed by miniaudio to achieve this goal. Note that the current +implementation may not be ideal - feedback and critiques are most welcome. + +The node graph API is not *entirely* lock-free. Only `ma_node_graph_read_pcm_frames()` is expected +to be lock-free. Attachment, detachment and uninitialization of nodes use locks to simplify the +implementation, but are crafted in a way such that such locking is not required when reading audio +data from the graph. Locking in these areas are achieved by means of spinlocks. + +The main complication with keeping `ma_node_graph_read_pcm_frames()` lock-free stems from the fact +that a node can be uninitialized, and it's memory potentially freed, while in the middle of being +processed on the audio thread. There are times when the audio thread will be referencing a node, +which means the uninitialization process of a node needs to make sure it delays returning until the +audio thread is finished so that control is not handed back to the caller thereby giving them a +chance to free the node's memory. + +When the audio thread is processing a node, it does so by reading from each of the output buses of +the node. In order for a node to process data for one of its output buses, it needs to read from +each of its input buses, and so on an so forth. It follows that once all output buses of a node +are detached, the node as a whole will be disconnected and no further processing will occur unless +it's output buses are reattached, which won't be happening when the node is being uninitialized. +By having `ma_node_detach_output_bus()` wait until the audio thread is finished with it, we can +simplify a few things, at the expense of making `ma_node_detach_output_bus()` a bit slower. By +doing this, the implementation of `ma_node_uninit()` becomes trivial - just detach all output +nodes, followed by each of the attachments to each of its input nodes, and then do any final clean +up. + +With the above design, the worst-case scenario is `ma_node_detach_output_bus()` taking as long as +it takes to process the output bus being detached. This will happen if it's called at just the +wrong moment where the audio thread has just iterated it and has just started processing. The +caller of `ma_node_detach_output_bus()` will stall until the audio thread is finished, which +includes the cost of recursively processing its inputs. This is the biggest compromise made with +the approach taken by miniaudio for its lock-free processing system. The cost of detaching nodes +earlier in the pipeline (data sources, for example) will be cheaper than the cost of detaching +higher level nodes, such as some kind of final post-processing endpoint. If you need to do mass +detachments, detach starting from the lowest level nodes and work your way towards the final +endpoint node (but don't try detaching the node graph's endpoint). If the audio thread is not +running, detachment will be fast and detachment in any order will be the same. The reason nodes +need to wait for their input attachments to complete is due to the potential for desyncs between +data sources. If the node was to terminate processing mid way through processing its inputs, +there's a chance that some of the underlying data sources will have been read, but then others not. +That will then result in a potential desynchronization when detaching and reattaching higher-level +nodes. A possible solution to this is to have an option when detaching to terminate processing +before processing all input attachments which should be fairly simple. + +Another compromise, albeit less significant, is locking when attaching and detaching nodes. This +locking is achieved by means of a spinlock in order to reduce memory overhead. A lock is present +for each input bus and output bus. When an output bus is connected to an input bus, both the output +bus and input bus is locked. This locking is specifically for attaching and detaching across +different threads and does not affect `ma_node_graph_read_pcm_frames()` in any way. The locking and +unlocking is mostly self-explanatory, but a slightly less intuitive aspect comes into it when +considering that iterating over attachments must not break as a result of attaching or detaching a +node while iteration is occurring. + +Attaching and detaching are both quite simple. When an output bus of a node is attached to an input +bus of another node, it's added to a linked list. Basically, an input bus is a linked list, where +each item in the list is and output bus. We have some intentional (and convenient) restrictions on +what can done with the linked list in order to simplify the implementation. First of all, whenever +something needs to iterate over the list, it must do so in a forward direction. Backwards iteration +is not supported. Also, items can only be added to the start of the list. + +The linked list is a doubly-linked list where each item in the list (an output bus) holds a pointer +to the next item in the list, and another to the previous item. A pointer to the previous item is +only required for fast detachment of the node - it is never used in iteration. This is an +important property because it means from the perspective of iteration, attaching and detaching of +an item can be done with a single atomic assignment. This is exploited by both the attachment and +detachment process. When attaching the node, the first thing that is done is the setting of the +local "next" and "previous" pointers of the node. After that, the item is "attached" to the list +by simply performing an atomic exchange with the head pointer. After that, the node is "attached" +to the list from the perspective of iteration. Even though the "previous" pointer of the next item +hasn't yet been set, from the perspective of iteration it's been attached because iteration will +only be happening in a forward direction which means the "previous" pointer won't actually ever get +used. The same general process applies to detachment. See `ma_node_attach_output_bus()` and +`ma_node_detach_output_bus()` for the implementation of this mechanism. + + + +8. Decoding +=========== +The `ma_decoder` API is used for reading audio files. Decoders are completely decoupled from +devices and can be used independently. Built-in support is included for the following formats: + + +---------+ + | Format | + +---------+ + | WAV | + | MP3 | + | FLAC | + +---------+ + +You can disable the built-in decoders by specifying one or more of the following options before the +miniaudio implementation: + + ```c + #define MA_NO_WAV + #define MA_NO_MP3 + #define MA_NO_FLAC + ``` + +miniaudio supports the ability to plug in custom decoders. See the section below for details on how +to use custom decoders. + +A decoder can be initialized from a file with `ma_decoder_init_file()`, a block of memory with +`ma_decoder_init_memory()`, or from data delivered via callbacks with `ma_decoder_init()`. Here is +an example for loading a decoder from a file: + + ```c + ma_decoder decoder; + ma_result result = ma_decoder_init_file("MySong.mp3", NULL, &decoder); + if (result != MA_SUCCESS) { + return false; // An error occurred. + } + + ... + + ma_decoder_uninit(&decoder); + ``` + +When initializing a decoder, you can optionally pass in a pointer to a `ma_decoder_config` object +(the `NULL` argument in the example above) which allows you to configure the output format, channel +count, sample rate and channel map: + + ```c + ma_decoder_config config = ma_decoder_config_init(ma_format_f32, 2, 48000); + ``` + +When passing in `NULL` for decoder config in `ma_decoder_init*()`, the output format will be the +same as that defined by the decoding backend. + +Data is read from the decoder as PCM frames. This will output the number of PCM frames actually +read. If this is less than the requested number of PCM frames it means you've reached the end. The +return value will be `MA_AT_END` if no samples have been read and the end has been reached. + + ```c + ma_result result = ma_decoder_read_pcm_frames(pDecoder, pFrames, framesToRead, &framesRead); + if (framesRead < framesToRead) { + // Reached the end. + } + ``` + +You can also seek to a specific frame like so: + + ```c + ma_result result = ma_decoder_seek_to_pcm_frame(pDecoder, targetFrame); + if (result != MA_SUCCESS) { + return false; // An error occurred. + } + ``` + +If you want to loop back to the start, you can simply seek back to the first PCM frame: + + ```c + ma_decoder_seek_to_pcm_frame(pDecoder, 0); + ``` + +When loading a decoder, miniaudio uses a trial and error technique to find the appropriate decoding +backend. This can be unnecessarily inefficient if the type is already known. In this case you can +use `encodingFormat` variable in the device config to specify a specific encoding format you want +to decode: + + ```c + decoderConfig.encodingFormat = ma_encoding_format_wav; + ``` + +See the `ma_encoding_format` enum for possible encoding formats. + +The `ma_decoder_init_file()` API will try using the file extension to determine which decoding +backend to prefer. + + +8.1. Custom Decoders +-------------------- +It's possible to implement a custom decoder and plug it into miniaudio. This is extremely useful +when you want to use the `ma_decoder` API, but need to support an encoding format that's not one of +the stock formats supported by miniaudio. This can be put to particularly good use when using the +`ma_engine` and/or `ma_resource_manager` APIs because they use `ma_decoder` internally. If, for +example, you wanted to support Opus, you can do so with a custom decoder (there if a reference +Opus decoder in the "extras" folder of the miniaudio repository which uses libopus + libopusfile). + +A custom decoder must implement a data source. A vtable called `ma_decoding_backend_vtable` needs +to be implemented which is then passed into the decoder config: + + ```c + ma_decoding_backend_vtable* pCustomBackendVTables[] = + { + &g_ma_decoding_backend_vtable_libvorbis, + &g_ma_decoding_backend_vtable_libopus + }; + + ... + + decoderConfig = ma_decoder_config_init_default(); + decoderConfig.pCustomBackendUserData = NULL; + decoderConfig.ppCustomBackendVTables = pCustomBackendVTables; + decoderConfig.customBackendCount = sizeof(pCustomBackendVTables) / sizeof(pCustomBackendVTables[0]); + ``` + +The `ma_decoding_backend_vtable` vtable has the following functions: + + ``` + onInit + onInitFile + onInitFileW + onInitMemory + onUninit + ``` + +There are only two functions that must be implemented - `onInit` and `onUninit`. The other +functions can be implemented for a small optimization for loading from a file path or memory. If +these are not specified, miniaudio will deal with it for you via a generic implementation. + +When you initialize a custom data source (by implementing the `onInit` function in the vtable) you +will need to output a pointer to a `ma_data_source` which implements your custom decoder. See the +section about data sources for details on how to implement this. Alternatively, see the +"custom_decoders" example in the miniaudio repository. + +The `onInit` function takes a pointer to some callbacks for the purpose of reading raw audio data +from some arbitrary source. You'll use these functions to read from the raw data and perform the +decoding. When you call them, you will pass in the `pReadSeekTellUserData` pointer to the relevant +parameter. + +The `pConfig` parameter in `onInit` can be used to configure the backend if appropriate. It's only +used as a hint and can be ignored. However, if any of the properties are relevant to your decoder, +an optimal implementation will handle the relevant properties appropriately. + +If memory allocation is required, it should be done so via the specified allocation callbacks if +possible (the `pAllocationCallbacks` parameter). + +If an error occurs when initializing the decoder, you should leave `ppBackend` unset, or set to +NULL, and make sure everything is cleaned up appropriately and an appropriate result code returned. +When multiple custom backends are specified, miniaudio will cycle through the vtables in the order +they're listed in the array that's passed into the decoder config so it's important that your +initialization routine is clean. + +When a decoder is uninitialized, the `onUninit` callback will be fired which will give you an +opportunity to clean up and internal data. + + + +9. Encoding +=========== +The `ma_encoding` API is used for writing audio files. The only supported output format is WAV. +This can be disabled by specifying the following option before the implementation of miniaudio: + + ```c + #define MA_NO_WAV + ``` + +An encoder can be initialized to write to a file with `ma_encoder_init_file()` or from data +delivered via callbacks with `ma_encoder_init()`. Below is an example for initializing an encoder +to output to a file. + + ```c + ma_encoder_config config = ma_encoder_config_init(ma_encoding_format_wav, FORMAT, CHANNELS, SAMPLE_RATE); + ma_encoder encoder; + ma_result result = ma_encoder_init_file("my_file.wav", &config, &encoder); + if (result != MA_SUCCESS) { + // Error + } + + ... + + ma_encoder_uninit(&encoder); + ``` + +When initializing an encoder you must specify a config which is initialized with +`ma_encoder_config_init()`. Here you must specify the file type, the output sample format, output +channel count and output sample rate. The following file types are supported: + + +------------------------+-------------+ + | Enum | Description | + +------------------------+-------------+ + | ma_encoding_format_wav | WAV | + +------------------------+-------------+ + +If the format, channel count or sample rate is not supported by the output file type an error will +be returned. The encoder will not perform data conversion so you will need to convert it before +outputting any audio data. To output audio data, use `ma_encoder_write_pcm_frames()`, like in the +example below: + + ```c + ma_uint64 framesWritten; + result = ma_encoder_write_pcm_frames(&encoder, pPCMFramesToWrite, framesToWrite, &framesWritten); + if (result != MA_SUCCESS) { + ... handle error ... + } + ``` + +The `framesWritten` variable will contain the number of PCM frames that were actually written. This +is optionally and you can pass in `NULL` if you need this. + +Encoders must be uninitialized with `ma_encoder_uninit()`. + + + +10. Data Conversion +=================== +A data conversion API is included with miniaudio which supports the majority of data conversion +requirements. This supports conversion between sample formats, channel counts (with channel +mapping) and sample rates. + + +10.1. Sample Format Conversion +------------------------------ +Conversion between sample formats is achieved with the `ma_pcm_*_to_*()`, `ma_pcm_convert()` and +`ma_convert_pcm_frames_format()` APIs. Use `ma_pcm_*_to_*()` to convert between two specific +formats. Use `ma_pcm_convert()` to convert based on a `ma_format` variable. Use +`ma_convert_pcm_frames_format()` to convert PCM frames where you want to specify the frame count +and channel count as a variable instead of the total sample count. + + +10.1.1. Dithering +----------------- +Dithering can be set using the ditherMode parameter. + +The different dithering modes include the following, in order of efficiency: + + +-----------+--------------------------+ + | Type | Enum Token | + +-----------+--------------------------+ + | None | ma_dither_mode_none | + | Rectangle | ma_dither_mode_rectangle | + | Triangle | ma_dither_mode_triangle | + +-----------+--------------------------+ + +Note that even if the dither mode is set to something other than `ma_dither_mode_none`, it will be +ignored for conversions where dithering is not needed. Dithering is available for the following +conversions: + + ``` + s16 -> u8 + s24 -> u8 + s32 -> u8 + f32 -> u8 + s24 -> s16 + s32 -> s16 + f32 -> s16 + ``` + +Note that it is not an error to pass something other than ma_dither_mode_none for conversions where +dither is not used. It will just be ignored. + + + +10.2. Channel Conversion +------------------------ +Channel conversion is used for channel rearrangement and conversion from one channel count to +another. The `ma_channel_converter` API is used for channel conversion. Below is an example of +initializing a simple channel converter which converts from mono to stereo. + + ```c + ma_channel_converter_config config = ma_channel_converter_config_init( + ma_format, // Sample format + 1, // Input channels + NULL, // Input channel map + 2, // Output channels + NULL, // Output channel map + ma_channel_mix_mode_default); // The mixing algorithm to use when combining channels. + + result = ma_channel_converter_init(&config, NULL, &converter); + if (result != MA_SUCCESS) { + // Error. + } + ``` + +To perform the conversion simply call `ma_channel_converter_process_pcm_frames()` like so: + + ```c + ma_result result = ma_channel_converter_process_pcm_frames(&converter, pFramesOut, pFramesIn, frameCount); + if (result != MA_SUCCESS) { + // Error. + } + ``` + +It is up to the caller to ensure the output buffer is large enough to accommodate the new PCM +frames. + +Input and output PCM frames are always interleaved. Deinterleaved layouts are not supported. + + +10.2.1. Channel Mapping +----------------------- +In addition to converting from one channel count to another, like the example above, the channel +converter can also be used to rearrange channels. When initializing the channel converter, you can +optionally pass in channel maps for both the input and output frames. If the channel counts are the +same, and each channel map contains the same channel positions with the exception that they're in +a different order, a simple shuffling of the channels will be performed. If, however, there is not +a 1:1 mapping of channel positions, or the channel counts differ, the input channels will be mixed +based on a mixing mode which is specified when initializing the `ma_channel_converter_config` +object. + +When converting from mono to multi-channel, the mono channel is simply copied to each output +channel. When going the other way around, the audio of each output channel is simply averaged and +copied to the mono channel. + +In more complicated cases blending is used. The `ma_channel_mix_mode_simple` mode will drop excess +channels and silence extra channels. For example, converting from 4 to 2 channels, the 3rd and 4th +channels will be dropped, whereas converting from 2 to 4 channels will put silence into the 3rd and +4th channels. + +The `ma_channel_mix_mode_rectangle` mode uses spacial locality based on a rectangle to compute a +simple distribution between input and output. Imagine sitting in the middle of a room, with +speakers on the walls representing channel positions. The `MA_CHANNEL_FRONT_LEFT` position can be +thought of as being in the corner of the front and left walls. + +Finally, the `ma_channel_mix_mode_custom_weights` mode can be used to use custom user-defined +weights. Custom weights can be passed in as the last parameter of +`ma_channel_converter_config_init()`. + +Predefined channel maps can be retrieved with `ma_channel_map_init_standard()`. This takes a +`ma_standard_channel_map` enum as its first parameter, which can be one of the following: + + +-----------------------------------+-----------------------------------------------------------+ + | Name | Description | + +-----------------------------------+-----------------------------------------------------------+ + | ma_standard_channel_map_default | Default channel map used by miniaudio. See below. | + | ma_standard_channel_map_microsoft | Channel map used by Microsoft's bitfield channel maps. | + | ma_standard_channel_map_alsa | Default ALSA channel map. | + | ma_standard_channel_map_rfc3551 | RFC 3551.

This | + | | is equivalent to the same | + | | mapping as the device. | + +---------------+---------------------------------+ + + + +10.3. Resampling +---------------- +Resampling is achieved with the `ma_resampler` object. To create a resampler object, do something +like the following: + + ```c + ma_resampler_config config = ma_resampler_config_init( + ma_format_s16, + channels, + sampleRateIn, + sampleRateOut, + ma_resample_algorithm_linear); + + ma_resampler resampler; + ma_result result = ma_resampler_init(&config, NULL, &resampler); + if (result != MA_SUCCESS) { + // An error occurred... + } + ``` + +Do the following to uninitialize the resampler: + + ```c + ma_resampler_uninit(&resampler); + ``` + +The following example shows how data can be processed + + ```c + ma_uint64 frameCountIn = 1000; + ma_uint64 frameCountOut = 2000; + ma_result result = ma_resampler_process_pcm_frames(&resampler, pFramesIn, &frameCountIn, pFramesOut, &frameCountOut); + if (result != MA_SUCCESS) { + // An error occurred... + } + + // At this point, frameCountIn contains the number of input frames that were consumed and frameCountOut contains the + // number of output frames written. + ``` + +To initialize the resampler you first need to set up a config (`ma_resampler_config`) with +`ma_resampler_config_init()`. You need to specify the sample format you want to use, the number of +channels, the input and output sample rate, and the algorithm. + +The sample format can be either `ma_format_s16` or `ma_format_f32`. If you need a different format +you will need to perform pre- and post-conversions yourself where necessary. Note that the format +is the same for both input and output. The format cannot be changed after initialization. + +The resampler supports multiple channels and is always interleaved (both input and output). The +channel count cannot be changed after initialization. + +The sample rates can be anything other than zero, and are always specified in hertz. They should be +set to something like 44100, etc. The sample rate is the only configuration property that can be +changed after initialization. + +The miniaudio resampler has built-in support for the following algorithms: + + +-----------+------------------------------+ + | Algorithm | Enum Token | + +-----------+------------------------------+ + | Linear | ma_resample_algorithm_linear | + | Custom | ma_resample_algorithm_custom | + +-----------+------------------------------+ + +The algorithm cannot be changed after initialization. + +Processing always happens on a per PCM frame basis and always assumes interleaved input and output. +De-interleaved processing is not supported. To process frames, use +`ma_resampler_process_pcm_frames()`. On input, this function takes the number of output frames you +can fit in the output buffer and the number of input frames contained in the input buffer. On +output these variables contain the number of output frames that were written to the output buffer +and the number of input frames that were consumed in the process. You can pass in NULL for the +input buffer in which case it will be treated as an infinitely large buffer of zeros. The output +buffer can also be NULL, in which case the processing will be treated as seek. + +The sample rate can be changed dynamically on the fly. You can change this with explicit sample +rates with `ma_resampler_set_rate()` and also with a decimal ratio with +`ma_resampler_set_rate_ratio()`. The ratio is in/out. + +Sometimes it's useful to know exactly how many input frames will be required to output a specific +number of frames. You can calculate this with `ma_resampler_get_required_input_frame_count()`. +Likewise, it's sometimes useful to know exactly how many frames would be output given a certain +number of input frames. You can do this with `ma_resampler_get_expected_output_frame_count()`. + +Due to the nature of how resampling works, the resampler introduces some latency. This can be +retrieved in terms of both the input rate and the output rate with +`ma_resampler_get_input_latency()` and `ma_resampler_get_output_latency()`. + + +10.3.1. Resampling Algorithms +----------------------------- +The choice of resampling algorithm depends on your situation and requirements. + + +10.3.1.1. Linear Resampling +--------------------------- +The linear resampler is the fastest, but comes at the expense of poorer quality. There is, however, +some control over the quality of the linear resampler which may make it a suitable option depending +on your requirements. + +The linear resampler performs low-pass filtering before or after downsampling or upsampling, +depending on the sample rates you're converting between. When decreasing the sample rate, the +low-pass filter will be applied before downsampling. When increasing the rate it will be performed +after upsampling. By default a fourth order low-pass filter will be applied. This can be configured +via the `lpfOrder` configuration variable. Setting this to 0 will disable filtering. + +The low-pass filter has a cutoff frequency which defaults to half the sample rate of the lowest of +the input and output sample rates (Nyquist Frequency). + +The API for the linear resampler is the same as the main resampler API, only it's called +`ma_linear_resampler`. + + +10.3.2. Custom Resamplers +------------------------- +You can implement a custom resampler by using the `ma_resample_algorithm_custom` resampling +algorithm and setting a vtable in the resampler config: + + ```c + ma_resampler_config config = ma_resampler_config_init(..., ma_resample_algorithm_custom); + config.pBackendVTable = &g_customResamplerVTable; + ``` + +Custom resamplers are useful if the stock algorithms are not appropriate for your use case. You +need to implement the required functions in `ma_resampling_backend_vtable`. Note that not all +functions in the vtable need to be implemented, but if it's possible to implement, they should be. + +You can use the `ma_linear_resampler` object for an example on how to implement the vtable. The +`onGetHeapSize` callback is used to calculate the size of any internal heap allocation the custom +resampler will need to make given the supplied config. When you initialize the resampler via the +`onInit` callback, you'll be given a pointer to a heap allocation which is where you should store +the heap allocated data. You should not free this data in `onUninit` because miniaudio will manage +it for you. + +The `onProcess` callback is where the actual resampling takes place. On input, `pFrameCountIn` +points to a variable containing the number of frames in the `pFramesIn` buffer and +`pFrameCountOut` points to a variable containing the capacity in frames of the `pFramesOut` buffer. +On output, `pFrameCountIn` should be set to the number of input frames that were fully consumed, +whereas `pFrameCountOut` should be set to the number of frames that were written to `pFramesOut`. + +The `onSetRate` callback is optional and is used for dynamically changing the sample rate. If +dynamic rate changes are not supported, you can set this callback to NULL. + +The `onGetInputLatency` and `onGetOutputLatency` functions are used for retrieving the latency in +input and output rates respectively. These can be NULL in which case latency calculations will be +assumed to be NULL. + +The `onGetRequiredInputFrameCount` callback is used to give miniaudio a hint as to how many input +frames are required to be available to produce the given number of output frames. Likewise, the +`onGetExpectedOutputFrameCount` callback is used to determine how many output frames will be +produced given the specified number of input frames. miniaudio will use these as a hint, but they +are optional and can be set to NULL if you're unable to implement them. + + + +10.4. General Data Conversion +----------------------------- +The `ma_data_converter` API can be used to wrap sample format conversion, channel conversion and +resampling into one operation. This is what miniaudio uses internally to convert between the format +requested when the device was initialized and the format of the backend's native device. The API +for general data conversion is very similar to the resampling API. Create a `ma_data_converter` +object like this: + + ```c + ma_data_converter_config config = ma_data_converter_config_init( + inputFormat, + outputFormat, + inputChannels, + outputChannels, + inputSampleRate, + outputSampleRate + ); + + ma_data_converter converter; + ma_result result = ma_data_converter_init(&config, NULL, &converter); + if (result != MA_SUCCESS) { + // An error occurred... + } + ``` + +In the example above we use `ma_data_converter_config_init()` to initialize the config, however +there's many more properties that can be configured, such as channel maps and resampling quality. +Something like the following may be more suitable depending on your requirements: + + ```c + ma_data_converter_config config = ma_data_converter_config_init_default(); + config.formatIn = inputFormat; + config.formatOut = outputFormat; + config.channelsIn = inputChannels; + config.channelsOut = outputChannels; + config.sampleRateIn = inputSampleRate; + config.sampleRateOut = outputSampleRate; + ma_channel_map_init_standard(ma_standard_channel_map_flac, config.channelMapIn, sizeof(config.channelMapIn)/sizeof(config.channelMapIn[0]), config.channelCountIn); + config.resampling.linear.lpfOrder = MA_MAX_FILTER_ORDER; + ``` + +Do the following to uninitialize the data converter: + + ```c + ma_data_converter_uninit(&converter, NULL); + ``` + +The following example shows how data can be processed + + ```c + ma_uint64 frameCountIn = 1000; + ma_uint64 frameCountOut = 2000; + ma_result result = ma_data_converter_process_pcm_frames(&converter, pFramesIn, &frameCountIn, pFramesOut, &frameCountOut); + if (result != MA_SUCCESS) { + // An error occurred... + } + + // At this point, frameCountIn contains the number of input frames that were consumed and frameCountOut contains the number + // of output frames written. + ``` + +The data converter supports multiple channels and is always interleaved (both input and output). +The channel count cannot be changed after initialization. + +Sample rates can be anything other than zero, and are always specified in hertz. They should be set +to something like 44100, etc. The sample rate is the only configuration property that can be +changed after initialization, but only if the `resampling.allowDynamicSampleRate` member of +`ma_data_converter_config` is set to `MA_TRUE`. To change the sample rate, use +`ma_data_converter_set_rate()` or `ma_data_converter_set_rate_ratio()`. The ratio must be in/out. +The resampling algorithm cannot be changed after initialization. + +Processing always happens on a per PCM frame basis and always assumes interleaved input and output. +De-interleaved processing is not supported. To process frames, use +`ma_data_converter_process_pcm_frames()`. On input, this function takes the number of output frames +you can fit in the output buffer and the number of input frames contained in the input buffer. On +output these variables contain the number of output frames that were written to the output buffer +and the number of input frames that were consumed in the process. You can pass in NULL for the +input buffer in which case it will be treated as an infinitely large +buffer of zeros. The output buffer can also be NULL, in which case the processing will be treated +as seek. + +Sometimes it's useful to know exactly how many input frames will be required to output a specific +number of frames. You can calculate this with `ma_data_converter_get_required_input_frame_count()`. +Likewise, it's sometimes useful to know exactly how many frames would be output given a certain +number of input frames. You can do this with `ma_data_converter_get_expected_output_frame_count()`. + +Due to the nature of how resampling works, the data converter introduces some latency if resampling +is required. This can be retrieved in terms of both the input rate and the output rate with +`ma_data_converter_get_input_latency()` and `ma_data_converter_get_output_latency()`. + + + +11. Filtering +============= + +11.1. Biquad Filtering +---------------------- +Biquad filtering is achieved with the `ma_biquad` API. Example: + + ```c + ma_biquad_config config = ma_biquad_config_init(ma_format_f32, channels, b0, b1, b2, a0, a1, a2); + ma_result result = ma_biquad_init(&config, NULL, &biquad); + if (result != MA_SUCCESS) { + // Error. + } + + ... + + ma_biquad_process_pcm_frames(&biquad, pFramesOut, pFramesIn, frameCount); + ``` + +Biquad filtering is implemented using transposed direct form 2. The numerator coefficients are b0, +b1 and b2, and the denominator coefficients are a0, a1 and a2. The a0 coefficient is required and +coefficients must not be pre-normalized. + +Supported formats are `ma_format_s16` and `ma_format_f32`. If you need to use a different format +you need to convert it yourself beforehand. When using `ma_format_s16` the biquad filter will use +fixed point arithmetic. When using `ma_format_f32`, floating point arithmetic will be used. + +Input and output frames are always interleaved. + +Filtering can be applied in-place by passing in the same pointer for both the input and output +buffers, like so: + + ```c + ma_biquad_process_pcm_frames(&biquad, pMyData, pMyData, frameCount); + ``` + +If you need to change the values of the coefficients, but maintain the values in the registers you +can do so with `ma_biquad_reinit()`. This is useful if you need to change the properties of the +filter while keeping the values of registers valid to avoid glitching. Do not use +`ma_biquad_init()` for this as it will do a full initialization which involves clearing the +registers to 0. Note that changing the format or channel count after initialization is invalid and +will result in an error. + + +11.2. Low-Pass Filtering +------------------------ +Low-pass filtering is achieved with the following APIs: + + +---------+------------------------------------------+ + | API | Description | + +---------+------------------------------------------+ + | ma_lpf1 | First order low-pass filter | + | ma_lpf2 | Second order low-pass filter | + | ma_lpf | High order low-pass filter (Butterworth) | + +---------+------------------------------------------+ + +Low-pass filter example: + + ```c + ma_lpf_config config = ma_lpf_config_init(ma_format_f32, channels, sampleRate, cutoffFrequency, order); + ma_result result = ma_lpf_init(&config, &lpf); + if (result != MA_SUCCESS) { + // Error. + } + + ... + + ma_lpf_process_pcm_frames(&lpf, pFramesOut, pFramesIn, frameCount); + ``` + +Supported formats are `ma_format_s16` and` ma_format_f32`. If you need to use a different format +you need to convert it yourself beforehand. Input and output frames are always interleaved. + +Filtering can be applied in-place by passing in the same pointer for both the input and output +buffers, like so: + + ```c + ma_lpf_process_pcm_frames(&lpf, pMyData, pMyData, frameCount); + ``` + +The maximum filter order is limited to `MA_MAX_FILTER_ORDER` which is set to 8. If you need more, +you can chain first and second order filters together. + + ```c + for (iFilter = 0; iFilter < filterCount; iFilter += 1) { + ma_lpf2_process_pcm_frames(&lpf2[iFilter], pMyData, pMyData, frameCount); + } + ``` + +If you need to change the configuration of the filter, but need to maintain the state of internal +registers you can do so with `ma_lpf_reinit()`. This may be useful if you need to change the sample +rate and/or cutoff frequency dynamically while maintaining smooth transitions. Note that changing the +format or channel count after initialization is invalid and will result in an error. + +The `ma_lpf` object supports a configurable order, but if you only need a first order filter you +may want to consider using `ma_lpf1`. Likewise, if you only need a second order filter you can use +`ma_lpf2`. The advantage of this is that they're lighter weight and a bit more efficient. + +If an even filter order is specified, a series of second order filters will be processed in a +chain. If an odd filter order is specified, a first order filter will be applied, followed by a +series of second order filters in a chain. + + +11.3. High-Pass Filtering +------------------------- +High-pass filtering is achieved with the following APIs: + + +---------+-------------------------------------------+ + | API | Description | + +---------+-------------------------------------------+ + | ma_hpf1 | First order high-pass filter | + | ma_hpf2 | Second order high-pass filter | + | ma_hpf | High order high-pass filter (Butterworth) | + +---------+-------------------------------------------+ + +High-pass filters work exactly the same as low-pass filters, only the APIs are called `ma_hpf1`, +`ma_hpf2` and `ma_hpf`. See example code for low-pass filters for example usage. + + +11.4. Band-Pass Filtering +------------------------- +Band-pass filtering is achieved with the following APIs: + + +---------+-------------------------------+ + | API | Description | + +---------+-------------------------------+ + | ma_bpf2 | Second order band-pass filter | + | ma_bpf | High order band-pass filter | + +---------+-------------------------------+ + +Band-pass filters work exactly the same as low-pass filters, only the APIs are called `ma_bpf2` and +`ma_hpf`. See example code for low-pass filters for example usage. Note that the order for +band-pass filters must be an even number which means there is no first order band-pass filter, +unlike low-pass and high-pass filters. + + +11.5. Notch Filtering +--------------------- +Notch filtering is achieved with the following APIs: + + +-----------+------------------------------------------+ + | API | Description | + +-----------+------------------------------------------+ + | ma_notch2 | Second order notching filter | + +-----------+------------------------------------------+ + + +11.6. Peaking EQ Filtering +------------------------- +Peaking filtering is achieved with the following APIs: + + +----------+------------------------------------------+ + | API | Description | + +----------+------------------------------------------+ + | ma_peak2 | Second order peaking filter | + +----------+------------------------------------------+ + + +11.7. Low Shelf Filtering +------------------------- +Low shelf filtering is achieved with the following APIs: + + +-------------+------------------------------------------+ + | API | Description | + +-------------+------------------------------------------+ + | ma_loshelf2 | Second order low shelf filter | + +-------------+------------------------------------------+ + +Where a high-pass filter is used to eliminate lower frequencies, a low shelf filter can be used to +just turn them down rather than eliminate them entirely. + + +11.8. High Shelf Filtering +-------------------------- +High shelf filtering is achieved with the following APIs: + + +-------------+------------------------------------------+ + | API | Description | + +-------------+------------------------------------------+ + | ma_hishelf2 | Second order high shelf filter | + +-------------+------------------------------------------+ + +The high shelf filter has the same API as the low shelf filter, only you would use `ma_hishelf` +instead of `ma_loshelf`. Where a low shelf filter is used to adjust the volume of low frequencies, +the high shelf filter does the same thing for high frequencies. + + + + +12. Waveform and Noise Generation +================================= + +12.1. Waveforms +--------------- +miniaudio supports generation of sine, square, triangle and sawtooth waveforms. This is achieved +with the `ma_waveform` API. Example: + + ```c + ma_waveform_config config = ma_waveform_config_init( + FORMAT, + CHANNELS, + SAMPLE_RATE, + ma_waveform_type_sine, + amplitude, + frequency); + + ma_waveform waveform; + ma_result result = ma_waveform_init(&config, &waveform); + if (result != MA_SUCCESS) { + // Error. + } + + ... + + ma_waveform_read_pcm_frames(&waveform, pOutput, frameCount); + ``` + +The amplitude, frequency, type, and sample rate can be changed dynamically with +`ma_waveform_set_amplitude()`, `ma_waveform_set_frequency()`, `ma_waveform_set_type()`, and +`ma_waveform_set_sample_rate()` respectively. + +You can invert the waveform by setting the amplitude to a negative value. You can use this to +control whether or not a sawtooth has a positive or negative ramp, for example. + +Below are the supported waveform types: + + +---------------------------+ + | Enum Name | + +---------------------------+ + | ma_waveform_type_sine | + | ma_waveform_type_square | + | ma_waveform_type_triangle | + | ma_waveform_type_sawtooth | + +---------------------------+ + + + +12.2. Noise +----------- +miniaudio supports generation of white, pink and Brownian noise via the `ma_noise` API. Example: + + ```c + ma_noise_config config = ma_noise_config_init( + FORMAT, + CHANNELS, + ma_noise_type_white, + SEED, + amplitude); + + ma_noise noise; + ma_result result = ma_noise_init(&config, &noise); + if (result != MA_SUCCESS) { + // Error. + } + + ... + + ma_noise_read_pcm_frames(&noise, pOutput, frameCount); + ``` + +The noise API uses simple LCG random number generation. It supports a custom seed which is useful +for things like automated testing requiring reproducibility. Setting the seed to zero will default +to `MA_DEFAULT_LCG_SEED`. + +The amplitude and seed can be changed dynamically with `ma_noise_set_amplitude()` and +`ma_noise_set_seed()` respectively. + +By default, the noise API will use different values for different channels. So, for example, the +left side in a stereo stream will be different to the right side. To instead have each channel use +the same random value, set the `duplicateChannels` member of the noise config to true, like so: + + ```c + config.duplicateChannels = MA_TRUE; + ``` + +Below are the supported noise types. + + +------------------------+ + | Enum Name | + +------------------------+ + | ma_noise_type_white | + | ma_noise_type_pink | + | ma_noise_type_brownian | + +------------------------+ + + + +13. Audio Buffers +================= +miniaudio supports reading from a buffer of raw audio data via the `ma_audio_buffer` API. This can +read from memory that's managed by the application, but can also handle the memory management for +you internally. Memory management is flexible and should support most use cases. + +Audio buffers are initialized using the standard configuration system used everywhere in miniaudio: + + ```c + ma_audio_buffer_config config = ma_audio_buffer_config_init( + format, + channels, + sizeInFrames, + pExistingData, + &allocationCallbacks); + + ma_audio_buffer buffer; + result = ma_audio_buffer_init(&config, &buffer); + if (result != MA_SUCCESS) { + // Error. + } + + ... + + ma_audio_buffer_uninit(&buffer); + ``` + +In the example above, the memory pointed to by `pExistingData` will *not* be copied and is how an +application can do self-managed memory allocation. If you would rather make a copy of the data, use +`ma_audio_buffer_init_copy()`. To uninitialize the buffer, use `ma_audio_buffer_uninit()`. + +Sometimes it can be convenient to allocate the memory for the `ma_audio_buffer` structure and the +raw audio data in a contiguous block of memory. That is, the raw audio data will be located +immediately after the `ma_audio_buffer` structure. To do this, use +`ma_audio_buffer_alloc_and_init()`: + + ```c + ma_audio_buffer_config config = ma_audio_buffer_config_init( + format, + channels, + sizeInFrames, + pExistingData, + &allocationCallbacks); + + ma_audio_buffer* pBuffer + result = ma_audio_buffer_alloc_and_init(&config, &pBuffer); + if (result != MA_SUCCESS) { + // Error + } + + ... + + ma_audio_buffer_uninit_and_free(&buffer); + ``` + +If you initialize the buffer with `ma_audio_buffer_alloc_and_init()` you should uninitialize it +with `ma_audio_buffer_uninit_and_free()`. In the example above, the memory pointed to by +`pExistingData` will be copied into the buffer, which is contrary to the behavior of +`ma_audio_buffer_init()`. + +An audio buffer has a playback cursor just like a decoder. As you read frames from the buffer, the +cursor moves forward. The last parameter (`loop`) can be used to determine if the buffer should +loop. The return value is the number of frames actually read. If this is less than the number of +frames requested it means the end has been reached. This should never happen if the `loop` +parameter is set to true. If you want to manually loop back to the start, you can do so with with +`ma_audio_buffer_seek_to_pcm_frame(pAudioBuffer, 0)`. Below is an example for reading data from an +audio buffer. + + ```c + ma_uint64 framesRead = ma_audio_buffer_read_pcm_frames(pAudioBuffer, pFramesOut, desiredFrameCount, isLooping); + if (framesRead < desiredFrameCount) { + // If not looping, this means the end has been reached. This should never happen in looping mode with valid input. + } + ``` + +Sometimes you may want to avoid the cost of data movement between the internal buffer and the +output buffer. Instead you can use memory mapping to retrieve a pointer to a segment of data: + + ```c + void* pMappedFrames; + ma_uint64 frameCount = frameCountToTryMapping; + ma_result result = ma_audio_buffer_map(pAudioBuffer, &pMappedFrames, &frameCount); + if (result == MA_SUCCESS) { + // Map was successful. The value in frameCount will be how many frames were _actually_ mapped, which may be + // less due to the end of the buffer being reached. + ma_copy_pcm_frames(pFramesOut, pMappedFrames, frameCount, pAudioBuffer->format, pAudioBuffer->channels); + + // You must unmap the buffer. + ma_audio_buffer_unmap(pAudioBuffer, frameCount); + } + ``` + +When you use memory mapping, the read cursor is increment by the frame count passed in to +`ma_audio_buffer_unmap()`. If you decide not to process every frame you can pass in a value smaller +than the value returned by `ma_audio_buffer_map()`. The disadvantage to using memory mapping is +that it does not handle looping for you. You can determine if the buffer is at the end for the +purpose of looping with `ma_audio_buffer_at_end()` or by inspecting the return value of +`ma_audio_buffer_unmap()` and checking if it equals `MA_AT_END`. You should not treat `MA_AT_END` +as an error when returned by `ma_audio_buffer_unmap()`. + + + +14. Ring Buffers +================ +miniaudio supports lock free (single producer, single consumer) ring buffers which are exposed via +the `ma_rb` and `ma_pcm_rb` APIs. The `ma_rb` API operates on bytes, whereas the `ma_pcm_rb` +operates on PCM frames. They are otherwise identical as `ma_pcm_rb` is just a wrapper around +`ma_rb`. + +Unlike most other APIs in miniaudio, ring buffers support both interleaved and deinterleaved +streams. The caller can also allocate their own backing memory for the ring buffer to use +internally for added flexibility. Otherwise the ring buffer will manage it's internal memory for +you. + +The examples below use the PCM frame variant of the ring buffer since that's most likely the one +you will want to use. To initialize a ring buffer, do something like the following: + + ```c + ma_pcm_rb rb; + ma_result result = ma_pcm_rb_init(FORMAT, CHANNELS, BUFFER_SIZE_IN_FRAMES, NULL, NULL, &rb); + if (result != MA_SUCCESS) { + // Error + } + ``` + +The `ma_pcm_rb_init()` function takes the sample format and channel count as parameters because +it's the PCM variant of the ring buffer API. For the regular ring buffer that operates on bytes you +would call `ma_rb_init()` which leaves these out and just takes the size of the buffer in bytes +instead of frames. The fourth parameter is an optional pre-allocated buffer and the fifth parameter +is a pointer to a `ma_allocation_callbacks` structure for custom memory allocation routines. +Passing in `NULL` for this results in `MA_MALLOC()` and `MA_FREE()` being used. + +Use `ma_pcm_rb_init_ex()` if you need a deinterleaved buffer. The data for each sub-buffer is +offset from each other based on the stride. To manage your sub-buffers you can use +`ma_pcm_rb_get_subbuffer_stride()`, `ma_pcm_rb_get_subbuffer_offset()` and +`ma_pcm_rb_get_subbuffer_ptr()`. + +Use `ma_pcm_rb_acquire_read()` and `ma_pcm_rb_acquire_write()` to retrieve a pointer to a section +of the ring buffer. You specify the number of frames you need, and on output it will set to what +was actually acquired. If the read or write pointer is positioned such that the number of frames +requested will require a loop, it will be clamped to the end of the buffer. Therefore, the number +of frames you're given may be less than the number you requested. + +After calling `ma_pcm_rb_acquire_read()` or `ma_pcm_rb_acquire_write()`, you do your work on the +buffer and then "commit" it with `ma_pcm_rb_commit_read()` or `ma_pcm_rb_commit_write()`. This is +where the read/write pointers are updated. When you commit you need to pass in the buffer that was +returned by the earlier call to `ma_pcm_rb_acquire_read()` or `ma_pcm_rb_acquire_write()` and is +only used for validation. The number of frames passed to `ma_pcm_rb_commit_read()` and +`ma_pcm_rb_commit_write()` is what's used to increment the pointers, and can be less that what was +originally requested. + +If you want to correct for drift between the write pointer and the read pointer you can use a +combination of `ma_pcm_rb_pointer_distance()`, `ma_pcm_rb_seek_read()` and +`ma_pcm_rb_seek_write()`. Note that you can only move the pointers forward, and you should only +move the read pointer forward via the consumer thread, and the write pointer forward by the +producer thread. If there is too much space between the pointers, move the read pointer forward. If +there is too little space between the pointers, move the write pointer forward. + +You can use a ring buffer at the byte level instead of the PCM frame level by using the `ma_rb` +API. This is exactly the same, only you will use the `ma_rb` functions instead of `ma_pcm_rb` and +instead of frame counts you will pass around byte counts. + +The maximum size of the buffer in bytes is `0x7FFFFFFF-(MA_SIMD_ALIGNMENT-1)` due to the most +significant bit being used to encode a loop flag and the internally managed buffers always being +aligned to `MA_SIMD_ALIGNMENT`. + +Note that the ring buffer is only thread safe when used by a single consumer thread and single +producer thread. + + + +15. Backends +============ +The following backends are supported by miniaudio. These are listed in order of default priority. +When no backend is specified when initializing a context or device, miniaudio will attempt to use +each of these backends in the order listed in the table below. + +Note that backends that are not usable by the build target will not be included in the build. For +example, ALSA, which is specific to Linux, will not be included in the Windows build. + + +-------------+-----------------------+--------------------------------------------------------+ + | Name | Enum Name | Supported Operating Systems | + +-------------+-----------------------+--------------------------------------------------------+ + | WASAPI | ma_backend_wasapi | Windows Vista+ | + | DirectSound | ma_backend_dsound | Windows XP+ | + | WinMM | ma_backend_winmm | Windows 95+ | + | Core Audio | ma_backend_coreaudio | macOS, iOS | + | sndio | ma_backend_sndio | OpenBSD | + | audio(4) | ma_backend_audio4 | NetBSD, OpenBSD | + | OSS | ma_backend_oss | FreeBSD | + | PulseAudio | ma_backend_pulseaudio | Cross Platform (disabled on Windows, BSD and Android) | + | ALSA | ma_backend_alsa | Linux | + | JACK | ma_backend_jack | Cross Platform (disabled on BSD and Android) | + | AAudio | ma_backend_aaudio | Android 8+ | + | OpenSL ES | ma_backend_opensl | Android (API level 16+) | + | Web Audio | ma_backend_webaudio | Web (via Emscripten) | + | Custom | ma_backend_custom | Cross Platform | + | Null | ma_backend_null | Cross Platform (not used on Web) | + +-------------+-----------------------+--------------------------------------------------------+ + +Some backends have some nuance details you may want to be aware of. + +15.1. WASAPI +------------ +- Low-latency shared mode will be disabled when using an application-defined sample rate which is + different to the device's native sample rate. To work around this, set `wasapi.noAutoConvertSRC` + to true in the device config. This is due to IAudioClient3_InitializeSharedAudioStream() failing + when the `AUDCLNT_STREAMFLAGS_AUTOCONVERTPCM` flag is specified. Setting wasapi.noAutoConvertSRC + will result in miniaudio's internal resampler being used instead which will in turn enable the + use of low-latency shared mode. + +15.2. PulseAudio +---------------- +- If you experience bad glitching/noise on Arch Linux, consider this fix from the Arch wiki: + https://wiki.archlinux.org/index.php/PulseAudio/Troubleshooting#Glitches,_skips_or_crackling. + Alternatively, consider using a different backend such as ALSA. + +15.3. Android +------------- +- To capture audio on Android, remember to add the RECORD_AUDIO permission to your manifest: + `` +- With OpenSL|ES, only a single ma_context can be active at any given time. This is due to a + limitation with OpenSL|ES. +- With AAudio, only default devices are enumerated. This is due to AAudio not having an enumeration + API (devices are enumerated through Java). You can however perform your own device enumeration + through Java and then set the ID in the ma_device_id structure (ma_device_id.aaudio) and pass it + to ma_device_init(). +- The backend API will perform resampling where possible. The reason for this as opposed to using + miniaudio's built-in resampler is to take advantage of any potential device-specific + optimizations the driver may implement. + +BSD +--- +- The sndio backend is currently only enabled on OpenBSD builds. +- The audio(4) backend is supported on OpenBSD, but you may need to disable sndiod before you can + use it. + +15.4. UWP +--------- +- UWP only supports default playback and capture devices. +- UWP requires the Microphone capability to be enabled in the application's manifest (Package.appxmanifest): + + ``` + + ... + + + + + ``` + +15.5. Web Audio / Emscripten +---------------------------- +- You cannot use `-std=c*` compiler flags, nor `-ansi`. This only applies to the Emscripten build. +- The first time a context is initialized it will create a global object called "miniaudio" whose + primary purpose is to act as a factory for device objects. +- Currently the Web Audio backend uses ScriptProcessorNode's, but this may need to change later as + they've been deprecated. +- Google has implemented a policy in their browsers that prevent automatic media output without + first receiving some kind of user input. The following web page has additional details: + https://developers.google.com/web/updates/2017/09/autoplay-policy-changes. Starting the device + may fail if you try to start playback without first handling some kind of user input. + + + +16. Optimization Tips +===================== +See below for some tips on improving performance. + +16.1. Low Level API +------------------- +- In the data callback, if your data is already clipped prior to copying it into the output buffer, + set the `noClip` config option in the device config to true. This will disable miniaudio's built + in clipping function. +- By default, miniaudio will pre-silence the data callback's output buffer. If you know that you + will always write valid data to the output buffer you can disable pre-silencing by setting the + `noPreSilence` config option in the device config to true. + +16.2. High Level API +-------------------- +- If a sound does not require doppler or pitch shifting, consider disabling pitching by + initializing the sound with the `MA_SOUND_FLAG_NO_PITCH` flag. +- If a sound does not require spatialization, disable it by initializing the sound with the + `MA_SOUND_FLAG_NO_SPATIALIZATION` flag. It can be re-enabled again post-initialization with + `ma_sound_set_spatialization_enabled()`. +- If you know all of your sounds will always be the same sample rate, set the engine's sample + rate to match that of the sounds. Likewise, if you're using a self-managed resource manager, + consider setting the decoded sample rate to match your sounds. By configuring everything to + use a consistent sample rate, sample rate conversion can be avoided. + + + +17. Miscellaneous Notes +======================= +- Automatic stream routing is enabled on a per-backend basis. Support is explicitly enabled for + WASAPI and Core Audio, however other backends such as PulseAudio may naturally support it, though + not all have been tested. +- When compiling with VC6 and earlier, decoding is restricted to files less than 2GB in size. This + is due to 64-bit file APIs not being available. +*/ + +#ifndef miniaudio_h +#define miniaudio_h + +#ifdef __cplusplus +extern "C" { +#endif + +#define MA_STRINGIFY(x) #x +#define MA_XSTRINGIFY(x) MA_STRINGIFY(x) + +#define MA_VERSION_MAJOR 0 +#define MA_VERSION_MINOR 11 +#define MA_VERSION_REVISION 22 +#define MA_VERSION_STRING MA_XSTRINGIFY(MA_VERSION_MAJOR) "."

These callbacks are grouped into two parts: context and device. There is one context +to many devices. A device is created from a context. + +The general flow goes like this: + + 1) A context is created with `onContextInit()` + 1a) Available devices can be enumerated with `onContextEnumerateDevices()` if required. + 1b) Detailed information about a device can be queried with `onContextGetDeviceInfo()` if required. + 2) A device is created from the context that was created in the first step using `onDeviceInit()`, and optionally a device ID that was + selected from device enumeration via `onContextEnumerateDevices()`. + 3) A device is started or stopped with `onDeviceStart()` / `onDeviceStop()` + 4) Data is delivered to and from the device by the backend. This is always done based on the native format returned by the prior call + to `onDeviceInit()`. Conversion between the device's native format and the format requested by the application will be handled by + miniaudio internally. + +Initialization of the context is quite simple. You need to do any necessary initialization of internal objects and then output the +callbacks defined in this structure. + +Once the context has been initialized you can initialize a device. Before doing so, however, the application may want to know which +physical devices are available. This is where `onContextEnumerateDevices()` comes in. This is fairly simple. For each device, fire the +given callback with, at a minimum, the basic information filled out in `ma_device_info`. When the callback returns `MA_FALSE`, enumeration +needs to stop and the `onContextEnumerateDevices()` function returns with a success code. + +Detailed device information can be retrieved from a device ID using `onContextGetDeviceInfo()`. This takes as input the device type and ID, +and on output returns detailed information about the device in `ma_device_info`. The `onContextGetDeviceInfo()` callback must handle the +case when the device ID is NULL, in which case information about the default device needs to be retrieved. + +Once the context has been created and the device ID retrieved (if using anything other than the default device), the device can be created. +This is a little bit more complicated than initialization of the context due to its more complicated configuration. When initializing a +device, a duplex device may be requested. This means a separate data format needs to be specified for both playback and capture. On input, +the data format is set to what the application wants. On output it's set to the native format which should match as closely as possible to +the requested format. The conversion between the format requested by the application and the device's native format will be handled +internally by miniaudio. + +On input, if the sample format is set to `ma_format_unknown`, the backend is free to use whatever sample format it desires, so long as it's +supported by miniaudio. When the channel count is set to 0, the backend should use the device's native channel count. The same applies for +sample rate. For the channel map, the default should be used when `ma_channel_map_is_blank()` returns true (all channels set to +`MA_CHANNEL_NONE`). On input, the `periodSizeInFrames` or `periodSizeInMilliseconds` option should always be set. The backend should +inspect both of these variables. If `periodSizeInFrames` is set, it should take priority, otherwise it needs to be derived from the period +size in milliseconds (`periodSizeInMilliseconds`) and the sample rate, keeping in mind that the sample rate may be 0, in which case the +sample rate will need to be determined before calculating the period size in frames. On output, all members of the `ma_device_descriptor` +object should be set to a valid value, except for `periodSizeInMilliseconds` which is optional (`periodSizeInFrames` *must* be set). + +Starting and stopping of the device is done with `onDeviceStart()` and `onDeviceStop()` and should be self-explanatory. If the backend uses +asynchronous reading and writing, `onDeviceStart()` and `onDeviceStop()` should always be implemented. + +The handling of data delivery between the application and the device is the most complicated part of the process. To make this a bit +easier, some helper callbacks are available. If the backend uses a blocking read/write style of API, the `onDeviceRead()` and +`onDeviceWrite()` callbacks can optionally be implemented. These are blocking and work just like reading and writing from a file. If the +backend uses a callback for data delivery, that callback must call `ma_device_handle_backend_data_callback()` from within its callback. +This allows miniaudio to then process any necessary data conversion and then pass it to the miniaudio data callback. + +If the backend requires absolute flexibility with its data delivery, it can optionally implement the `onDeviceDataLoop()` callback +which will allow it to implement the logic that will run on the audio thread. This is much more advanced and is completely optional. + +The audio thread should run data delivery logic in a loop while `ma_device_get_state() == ma_device_state_started` and no errors have been +encountered. Do not start or stop the device here. That will be handled from outside the `onDeviceDataLoop()` callback. + +The invocation of the `onDeviceDataLoop()` callback will be handled by miniaudio. When you start the device, miniaudio will fire this +callback. When the device is stopped, the `ma_device_get_state() == ma_device_state_started` condition will fail and the loop will be terminated +which will then fall through to the part that stops the device. For an example on how to implement the `onDeviceDataLoop()` callback, +look at `ma_device_audio_thread__default_read_write()`. Implement the `onDeviceDataLoopWakeup()` callback if you need a mechanism to +wake up the audio thread. + +If the backend supports an optimized retrieval of device information from an initialized `ma_device` object, it should implement the +`onDeviceGetInfo()` callback. This is optional, in which case it will fall back to `onContextGetDeviceInfo()` which is less efficient. +*/ +struct ma_backend_callbacks +{ + ma_result (* onContextInit)(ma_context* pContext, const ma_context_config* pConfig, ma_backend_callbacks* pCallbacks); + ma_result (* onContextUninit)(ma_context* pContext); + ma_result (* onContextEnumerateDevices)(ma_context* pContext, ma_enum_devices_callback_proc callback, void* pUserData); + ma_result (* onContextGetDeviceInfo)(ma_context* pContext, ma_device_type deviceType, const ma_device_id* pDeviceID, ma_device_info* pDeviceInfo); + ma_result (* onDeviceInit)(ma_device* pDevice, const ma_device_config* pConfig, ma_device_descriptor* pDescriptorPlayback, ma_device_descriptor* pDescriptorCapture); + ma_result (* onDeviceUninit)(ma_device* pDevice); + ma_result (* onDeviceStart)(ma_device* pDevice); + ma_result (* onDeviceStop)(ma_device* pDevice); + ma_result (* onDeviceRead)(ma_device* pDevice, void* pFrames, ma_uint32 frameCount, ma_uint32* pFramesRead); + ma_result (* onDeviceWrite)(ma_device* pDevice, const void* pFrames, ma_uint32 frameCount, ma_uint32* pFramesWritten); + ma_result (* onDeviceDataLoop)(ma_device* pDevice); + ma_result (* onDeviceDataLoopWakeup)(ma_device* pDevice); + ma_result (* onDeviceGetInfo)(ma_device* pDevice, ma_device_type type, ma_device_info* pDeviceInfo); +}; + +struct ma_context_config +{ + ma_log* pLog; + ma_thread_priority threadPriority; + size_t threadStackSize; + void* pUserData; + ma_allocation_callbacks allocationCallbacks; + struct + { + ma_handle hWnd; /* HWND.

The idea is you send or receive audio data from the device to either play it back through a speaker, or capture it +from a microphone. Whether or not you should send or receive data from the device (or both) depends on the type of device you are initializing which can be +playback, capture, full-duplex or loopback. (Note that loopback mode is only supported on select backends.) Sending and receiving audio data to and from the +device is done via a callback which is fired by miniaudio at periodic time intervals. + +The frequency at which data is delivered to and from a device depends on the size of its period. The size of the period can be defined in terms of PCM frames +or milliseconds, whichever is more convenient. Generally speaking, the smaller the period, the lower the latency at the expense of higher CPU usage and +increased risk of glitching due to the more frequent and granular data deliver intervals. The size of a period will depend on your requirements, but +miniaudio's defaults should work fine for most scenarios.

See below for details. + + periodSizeInMilliseconds + The desired size of a period in milliseconds. If this is 0, `periodSizeInFrames` will be used instead. If both are 0 the default buffer size will be + used depending on the selected performance profile. The value affects latency. See below for details. + + periods + The number of periods making up the device's entire buffer. The total buffer size is `periodSizeInFrames` or `periodSizeInMilliseconds` multiplied by + this value. This is just a hint as backends will be the ones who ultimately decide how your periods will be configured. + + performanceProfile + A hint to miniaudio as to the performance requirements of your program. Can be either `ma_performance_profile_low_latency` (default) or + `ma_performance_profile_conservative`. This mainly affects the size of default buffers and can usually be left at its default value. + + noPreSilencedOutputBuffer + When set to true, the contents of the output buffer passed into the data callback will be left undefined.

You can use this to avoid the overhead of zeroing out the buffer if you can guarantee that your data + callback will write to every sample in the output buffer, or if you are doing your own clearing. + + noClip + When set to true, the contents of the output buffer are left alone after returning and it will be left up to the backend itself to decide whether or + not to clip. When set to false (default), the contents of the output buffer passed into the data callback will be clipped after returning. This only + applies when the playback sample format is f32. + + noDisableDenormals + By default, miniaudio will disable denormals when the data callback is called.

You can access this directly from the device object like `device.pUserData`. + + resampling.algorithm + The resampling algorithm to use when miniaudio needs to perform resampling between the rate specified by `sampleRate` and the device's native rate. The + default value is `ma_resample_algorithm_linear`, and the quality can be configured with `resampling.linear.lpfOrder`. + + resampling.pBackendVTable + A pointer to an optional vtable that can be used for plugging in a custom resampler. + + resampling.pBackendUserData + A pointer that will passed to callbacks in pBackendVTable. + + resampling.linear.lpfOrder + The linear resampler applies a low-pass filter as part of its processing for anti-aliasing. This setting controls the order of the filter. The higher + the value, the better the quality, in general. Setting this to 0 will disable low-pass filtering altogether. The maximum value is + `MA_MAX_FILTER_ORDER`. The default value is `min(4, MA_MAX_FILTER_ORDER)`. + + playback.pDeviceID + A pointer to a `ma_device_id` structure containing the ID of the playback device to initialize.

You can then fall back to shared mode if desired by changing this to + ma_share_mode_shared and reinitializing. + + capture.pDeviceID + A pointer to a `ma_device_id` structure containing the ID of the capture device to initialize. Setting this NULL (default) will use the system's + default capture device. Retrieve the device ID from the `ma_device_info` structure, which can be retrieved using device enumeration. + + capture.format + The sample format to use for capture. When set to `ma_format_unknown` the device's native format will be used.

Note that if you specify + exclusive mode, but it's not supported by the backend, initialization will fail. You can then fall back to shared mode if desired by changing this to + ma_share_mode_shared and reinitializing. + + wasapi.noAutoConvertSRC + WASAPI only. When set to true, disables WASAPI's automatic resampling and forces the use of miniaudio's resampler. Defaults to false. + + wasapi.noDefaultQualitySRC + WASAPI only. Only used when `wasapi.noAutoConvertSRC` is set to false.

Defaults to MA_PA_CHANNEL_MAP_AIFF. + + coreaudio.allowNominalSampleRateChange + Core Audio only. Desktop only. When enabled, allows the sample rate of the device to be changed at the operating system level. This + is disabled by default in order to prevent intrusive changes to the user's system. This is useful if you want to use a sample rate + that is known to be natively supported by the hardware thereby avoiding the cost of resampling. When set to true, miniaudio will + find the closest match between the sample rate requested in the device config and the sample rates natively supported by the + hardware. When set to false, the sample rate currently set by the operating system will always be used. + + opensl.streamType + OpenSL only. Explicitly sets the stream type. If left unset (`ma_opensl_stream_type_default`), the + stream type will be left unset. Think of this as the type of audio you're playing. + + opensl.recordingPreset + OpenSL only. Explicitly sets the type of recording your program will be doing. When left + unset, the recording preset will be left unchanged. + + aaudio.usage + AAudio only. Explicitly sets the nature of the audio the program will be consuming. When + left unset, the usage will be left unchanged. + + aaudio.contentType + AAudio only. Sets the content type. When left unset, the content type will be left unchanged. + + aaudio.inputPreset + AAudio only. Explicitly sets the type of recording your program will be doing. When left + unset, the input preset will be left unchanged. + + aaudio.noAutoStartAfterReroute + AAudio only. Controls whether or not the device should be automatically restarted after a + stream reroute. When set to false (default) the device will be restarted automatically; + otherwise the device will be stopped. + + +Once initialized, the device's config is immutable. If you need to change the config you will need to initialize a new device. + +After initializing the device it will be in a stopped state. To start it, use `ma_device_start()`. + +If both `periodSizeInFrames` and `periodSizeInMilliseconds` are set to zero, it will default to `MA_DEFAULT_PERIOD_SIZE_IN_MILLISECONDS_LOW_LATENCY` or +`MA_DEFAULT_PERIOD_SIZE_IN_MILLISECONDS_CONSERVATIVE`, depending on whether or not `performanceProfile` is set to `ma_performance_profile_low_latency` or +`ma_performance_profile_conservative`. + +If you request exclusive mode and the backend does not support it an error will be returned. For robustness, you may want to first try initializing the device +in exclusive mode, and then fall back to shared mode if required. Alternatively you can just request shared mode (the default if you leave it unset in the +config) which is the most reliable option. Some backends do not have a practical way of choosing whether or not the device should be exclusive or not (ALSA, +for example) in which case it just acts as a hint. Unless you have special requirements you should try avoiding exclusive mode as it's intrusive to the user. +Starting with Windows 10, miniaudio will use low-latency shared mode where possible which may make exclusive mode unnecessary. + +When sending or receiving data to/from a device, miniaudio will internally perform a format conversion to convert between the format specified by the config +and the format used internally by the backend. If you pass in 0 for the sample format, channel count, sample rate _and_ channel map, data transmission will run +on an optimized pass-through fast path. You can retrieve the format, channel count and sample rate by inspecting the `playback/capture.format`, +`playback/capture.channels` and `sampleRate` members of the device object. + +When compiling for UWP you must ensure you call this function on the main UI thread because the operating system may need to present the user with a message +asking for permissions. Please refer to the official documentation for ActivateAudioInterfaceAsync() for more information. + +ALSA Specific: When initializing the default device, requesting shared mode will try using the "dmix" device for playback and the "dsnoop" device for capture. +If these fail it will try falling back to the "hw" device. + + +Example 1 - Simple Initialization +--------------------------------- +This example shows how to initialize a simple playback device using a standard configuration.

This is a brief description of what's going on +in the PulseAudio backend. I apologize if this gets a bit ranty for your liking - you might want to skip this discussion. + +PulseAudio has something they call the "Simple API", which unfortunately isn't suitable for miniaudio. I've not seen anywhere where it +allows you to enumerate over devices, nor does it seem to support the ability to stop and start streams. Looking at the documentation, it +appears as though the stream is constantly running and you prevent sound from being emitted or captured by simply not calling the read or +write functions. This is not a professional solution as it would be much better to *actually* stop the underlying stream. Perhaps the +simple API has some smarts to do this automatically, but I'm not sure. Another limitation with the simple API is that it seems inefficient +when you want to have multiple streams to a single context. For these reasons, miniaudio is not using the simple API. + +Since we're not using the simple API, we're left with the asynchronous API as our only other option. And boy, is this where it starts to +get fun, and I don't mean that in a good way... + +The problems start with the very name of the API - "asynchronous". Yes, this is an asynchronous oriented API which means your commands +don't immediately take effect. You instead need to issue your commands, and then wait for them to complete. The waiting mechanism is +enabled through the use of a "main loop". In the asynchronous API you cannot get away from the main loop, and the main loop is where almost +all of PulseAudio's problems stem from. + +When you first initialize PulseAudio you need an object referred to as "main loop". You can implement this yourself by defining your own +vtable, but it's much easier to just use one of the built-in main loop implementations. There's two generic implementations called +pa_mainloop and pa_threaded_mainloop, and another implementation specific to GLib called pa_glib_mainloop. We're using pa_threaded_mainloop +because it simplifies management of the worker thread. The idea of the main loop object is pretty self explanatory - you're supposed to use +it to implement a worker thread which runs in a loop. The main loop is where operations are actually executed. + +To initialize the main loop, you just use `pa_threaded_mainloop_new()`. This is the first function you'll call. You can then get a pointer +to the vtable with `pa_threaded_mainloop_get_api()` (the main loop vtable is called `pa_mainloop_api`). Again, you can bypass the threaded +main loop object entirely and just implement `pa_mainloop_api` directly, but there's no need for it unless you're doing something extremely +specialized such as if you want to integrate it into your application's existing main loop infrastructure. + +(EDIT 2021-01-26: miniaudio is no longer using `pa_threaded_mainloop` due to this issue: https://github.com/mackron/miniaudio/issues/262. +It is now using `pa_mainloop` which turns out to be a simpler solution anyway. The rest of this rant still applies, however.) + +Once you have your main loop vtable (the `pa_mainloop_api` object) you can create the PulseAudio context. This is very similar to +miniaudio's context and they map to each other quite well. You have one context to many streams, which is basically the same as miniaudio's +one `ma_context` to many `ma_device`s. Here's where it starts to get annoying, however. When you first create the PulseAudio context, which +is done with `pa_context_new()`, it's not actually connected to anything. When you connect, you call `pa_context_connect()`. However, if +you remember, PulseAudio is an asynchronous API. That means you cannot just assume the context is connected after `pa_context_context()` +has returned. You instead need to wait for it to connect. To do this, you need to either wait for a callback to get fired, which you can +set with `pa_context_set_state_callback()`, or you can continuously poll the context's state. Either way, you need to run this in a loop. +All objects from here out are created from the context, and, I believe, you can't be creating these objects until the context is connected. +This waiting loop is therefore unavoidable. In order for the waiting to ever complete, however, the main loop needs to be running. Before +attempting to connect the context, the main loop needs to be started with `pa_threaded_mainloop_start()`. + +The reason for this asynchronous design is to support cases where you're connecting to a remote server, say through a local network or an +internet connection. However, the *VAST* majority of cases don't involve this at all - they just connect to a local "server" running on the +host machine. The fact that this would be the default rather than making `pa_context_connect()` synchronous tends to boggle the mind. + +Once the context has been created and connected you can start creating a stream. A PulseAudio stream is analogous to miniaudio's device. +The initialization of a stream is fairly standard - you configure some attributes (analogous to miniaudio's device config) and then call +`pa_stream_new()` to actually create it. Here is where we start to get into "operations". When configuring the stream, you can get +information about the source (such as sample format, sample rate, etc.), however it's not synchronous. Instead, a `pa_operation` object +is returned from `pa_context_get_source_info_by_name()` (capture) or `pa_context_get_sink_info_by_name()` (playback). Then, you need to +run a loop (again!) to wait for the operation to complete which you can determine via a callback or polling, just like we did with the +context. Then, as an added bonus, you need to decrement the reference counter of the `pa_operation` object to ensure memory is cleaned up. +All of that just to retrieve basic information about a device! + +Once the basic information about the device has been retrieved, miniaudio can now create the stream with `ma_stream_new()`. Like the +context, this needs to be connected. But we need to be careful here, because we're now about to introduce one of the most horrific design +choices in PulseAudio. + +PulseAudio allows you to specify a callback that is fired when data can be written to or read from a stream. The language is important here +because PulseAudio takes it literally, specifically the "can be". You would think these callbacks would be appropriate as the place for +writing and reading data to and from the stream, and that would be right, except when it's not. When you initialize the stream, you can +set a flag that tells PulseAudio to not start the stream automatically. This is required because miniaudio does not auto-start devices +straight after initialization - you need to call `ma_device_start()` manually. The problem is that even when this flag is specified, +PulseAudio will immediately fire its write or read callback. This is *technically* correct (based on the wording in the documentation) +because indeed, data *can* be written at this point. The problem is that it's not *practical*. It makes sense that the write/read callback +would be where a program will want to write or read data to or from the stream, but when it's called before the application has even +requested that the stream be started, it's just not practical because the program probably isn't ready for any kind of data delivery at +that point (it may still need to load files or whatnot). Instead, this callback should only be fired when the application requests the +stream be started which is how it works with literally *every* other callback-based audio API. Since miniaudio forbids firing of the data +callback until the device has been started (as it should be with *all* callback based APIs), logic needs to be added to ensure miniaudio +doesn't just blindly fire the application-defined data callback from within the PulseAudio callback before the stream has actually been +started. The device state is used for this - if the state is anything other than `ma_device_state_starting` or `ma_device_state_started`, the main data +callback is not fired. + +This, unfortunately, is not the end of the problems with the PulseAudio write callback. Any normal callback based audio API will +continuously fire the callback at regular intervals based on the size of the internal buffer. This will only ever be fired when the device +is running, and will be fired regardless of whether or not the user actually wrote anything to the device/stream. This not the case in +PulseAudio. In PulseAudio, the data callback will *only* be called if you wrote something to it previously. That means, if you don't call +`pa_stream_write()`, the callback will not get fired. On the surface you wouldn't think this would matter because you should be always +writing data, and if you don't have anything to write, just write silence. That's fine until you want to drain the stream. You see, if +you're continuously writing data to the stream, the stream will never get drained! That means in order to drain the stream, you need to +*not* write data to it! But remember, when you don't write data to the stream, the callback won't get fired again! Why is draining +important? Because that's how we've defined stopping to work in miniaudio. In miniaudio, stopping the device requires it to be drained +before returning from ma_device_stop(). So we've stopped the device, which requires us to drain, but draining requires us to *not* write +data to the stream (or else it won't ever complete draining), but not writing to the stream means the callback won't get fired again! + +This becomes a problem when stopping and then restarting the device. When the device is stopped, it's drained, which requires us to *not* +write anything to the stream. But then, since we didn't write anything to it, the write callback will *never* get called again if we just +resume the stream naively. This means that starting the stream requires us to write data to the stream from outside the callback. This +disconnect is something PulseAudio has got seriously wrong - there should only ever be a single source of data delivery, that being the +callback. (I have tried using `pa_stream_flush()` to trigger the write callback to fire, but this just doesn't work for some reason.) + +Once you've created the stream, you need to connect it which involves the whole waiting procedure. This is the same process as the context, +only this time you'll poll for the state with `pa_stream_get_status()`. The starting and stopping of a streaming is referred to as +"corking" in PulseAudio. The analogy is corking a barrel. To start the stream, you uncork it, to stop it you cork it. Personally I think +it's silly - why would you not just call it "starting" and "stopping" like any other normal audio API? Anyway, the act of corking is, you +guessed it, asynchronous. This means you'll need our waiting loop as usual. Again, why this asynchronous design is the default is +absolutely beyond me. Would it really be that hard to just make it run synchronously? + +Teardown is pretty simple (what?!). It's just a matter of calling the relevant `_unref()` function on each object in reverse order that +they were initialized in. + +That's about it from the PulseAudio side. A bit ranty, I know, but they really need to fix that main loop and callback system. They're +embarrassingly unpractical. The main loop thing is an easy fix - have synchronous versions of all APIs. If an application wants these to +run asynchronously, they can execute them in a separate thread themselves. The desire to run these asynchronously is such a niche +requirement - it makes no sense to make it the default. The stream write callback needs to be change, or an alternative provided, that is +constantly fired, regardless of whether or not `pa_stream_write()` has been called, and it needs to take a pointer to a buffer as a +parameter which the program just writes to directly rather than having to call `pa_stream_writable_size()` and `pa_stream_write()`. These +changes alone will change PulseAudio from one of the worst audio APIs to one of the best. +*/ + + +/* +It is assumed pulseaudio.h is available when linking at compile time.

For my own purposes, and for anybody out there whose +needing to figure out how this darn thing works, I'm going to outline a few things here. + +Since miniaudio is a fairly low-level API, one of the things it needs is control over specific devices, and it needs to be +able to identify whether or not it can be used as playback and/or capture. The AudioObject API is the only one I've seen +that supports this level of detail. There was some public domain sample code I stumbled across that used the AudioComponent +and AudioUnit APIs, but I couldn't see anything that gave low-level control over device selection and capabilities (the +distinction between playback and capture in particular). Therefore, miniaudio is using the AudioObject API. + +Most (all?) functions in the AudioObject API take a AudioObjectID as its input. This is the device identifier. When +retrieving global information, such as the device list, you use kAudioObjectSystemObject. When retrieving device-specific +data, you pass in the ID for that device. In order to retrieve device-specific IDs you need to enumerate over each of the +devices. This is done using the AudioObjectGetPropertyDataSize() and AudioObjectGetPropertyData() APIs which seem to be +the central APIs for retrieving information about the system and specific devices. + +To use the AudioObjectGetPropertyData() API you need to use the notion of a property address. A property address is a +structure with three variables and is used to identify which property you are getting or setting. The first is the "selector" +which is basically the specific property that you're wanting to retrieve or set. The second is the "scope", which is +typically set to kAudioObjectPropertyScopeGlobal, kAudioObjectPropertyScopeInput for input-specific properties and +kAudioObjectPropertyScopeOutput for output-specific properties. The last is the "element" which is always set to +kAudioObjectPropertyElementMain in miniaudio's case. I don't know of any cases where this would be set to anything different. + +Back to the earlier issue of device retrieval, you first use the AudioObjectGetPropertyDataSize() API to retrieve the size +of the raw data which is just a list of AudioDeviceID's. You use the kAudioObjectSystemObject AudioObjectID, and a property +address with the kAudioHardwarePropertyDevices selector and the kAudioObjectPropertyScopeGlobal scope. Once you have the +size, allocate a block of memory of that size and then call AudioObjectGetPropertyData(). The data is just a list of +AudioDeviceID's so just do "dataSize/sizeof(AudioDeviceID)" to know the device count. +*/ + +#if defined(MA_APPLE_MOBILE) +static void ma_device__on_notification_interruption_began(ma_device* pDevice) +{ + ma_device__on_notification(ma_device_notification_init(pDevice, ma_device_notification_type_interruption_began));

The important things - to know about this: - - 1. The best mathematically-behaved version of alpha to use is - called "premultiplied alpha", in which the other color channels - have had the alpha value multiplied in. If you use premultiplied - alpha, linear filtering (such as image resampling done by this - library, or performed in texture units on GPUs) does the "right - thing". While premultiplied alpha is standard in the movie CGI - industry, it is still uncommon in the videogame/real-time world. - - If you linearly filter non-premultiplied alpha, strange effects - occur. (For example, the 50/50 average of 99% transparent bright green - and 1% transparent black produces 50% transparent dark green when - non-premultiplied, whereas premultiplied it produces 50% - transparent near-black. The former introduces green energy - that doesn't exist in the source image.) - - 2. Artists should not edit premultiplied-alpha images; artists - want non-premultiplied alpha images. Thus, art tools generally output - non-premultiplied alpha images. - - 3. You will get best results in most cases by converting images - to premultiplied alpha before processing them mathematically. - - 4. If you pass the flag STBIR_FLAG_ALPHA_PREMULTIPLIED, the - resizer does not do anything special for the alpha channel; - it is resampled identically to other channels. This produces - the correct results for premultiplied-alpha images, but produces - less-than-ideal results for non-premultiplied-alpha images. - - 5. If you do not pass the flag STBIR_FLAG_ALPHA_PREMULTIPLIED, - then the resizer weights the contribution of input pixels - based on their alpha values, or, equivalently, it multiplies - the alpha value into the color channels, resamples, then divides - by the resultant alpha value. Input pixels which have alpha=0 do - not contribute at all to output pixels unless _all_ of the input - pixels affecting that output pixel have alpha=0, in which case - the result for that pixel is the same as it would be without - STBIR_FLAG_ALPHA_PREMULTIPLIED. However, this is only true for - input images in integer formats. For input images in float format, - input pixels with alpha=0 have no effect, and output pixels - which have alpha=0 will be 0 in all channels. (For float images, - you can manually achieve the same result by adding a tiny epsilon - value to the alpha channel of every image, and then subtracting - or clamping it at the end.) - - 6. You can suppress the behavior described in #5 and make - all-0-alpha pixels have 0 in all channels by #defining - STBIR_NO_ALPHA_EPSILON. - - 7. You can separately control whether the alpha channel is - interpreted as linear or affected by the colorspace. By default - it is linear; you almost never want to apply the colorspace. - (For example, graphics hardware does not apply sRGB conversion - to the alpha channel.) - - CONTRIBUTORS - Jorge L Rodriguez: Implementation - Sean Barrett: API design, optimizations - Aras Pranckevicius: bugfix - Nathan Reed: warning fixes - - REVISIONS - 0.95 (2017-07-23) fixed warnings - 0.94 (2017-03-18) fixed warnings - 0.93 (2017-03-03) fixed bug with certain combinations of heights - 0.92 (2017-01-02) fix integer overflow on large (>2GB) images - 0.91 (2016-04-02) fix warnings; fix handling of subpixel regions - 0.90 (2014-09-17) first released version - - LICENSE - See end of file for license information. - - TODO - Don't decode all of the image data when only processing a partial tile - Don't use full-width decode buffers when only processing a partial tile - When processing wide images, break processing into tiles so data fits in L1 cache - Installable filters? - Resize that respects alpha test coverage - (Reference code: FloatImage::alphaTestCoverage and FloatImage::scaleAlphaToCoverage: - https://code.google.com/p/nvidia-texture-tools/source/browse/trunk/src/nvimage/FloatImage.cpp ) -*/ - -#ifndef STBIR_INCLUDE_STB_IMAGE_RESIZE_H -#define STBIR_INCLUDE_STB_IMAGE_RESIZE_H - -#ifdef _MSC_VER -typedef unsigned char stbir_uint8; -typedef unsigned short stbir_uint16; -typedef unsigned int stbir_uint32; -#else -#include -typedef uint8_t stbir_uint8; -typedef uint16_t stbir_uint16; -typedef uint32_t stbir_uint32; -#endif - -#ifdef STB_IMAGE_RESIZE_STATIC -#define STBIRDEF static -#else -#ifdef __cplusplus -#define STBIRDEF extern "C" -#else -#define STBIRDEF extern -#endif -#endif - - -////////////////////////////////////////////////////////////////////////////// -// -// Easy-to-use API: -// -// * "input pixels" points to an array of image data with 'num_channels' channels (e.g. RGB=3, RGBA=4) -// * input_w is input image width (x-axis), input_h is input image height (y-axis) -// * stride is the offset between successive rows of image data in memory, in bytes. you can -// specify 0 to mean packed continuously in memory -// * alpha channel is treated identically to other channels. -// * colorspace is linear or sRGB as specified by function name -// * returned result is 1 for success or 0 in case of an error. -// #define STBIR_ASSERT() to trigger an assert on parameter validation errors. -// * Memory required grows approximately linearly with input and output size, but with -// discontinuities at input_w == output_w and input_h == output_h. -// * These functions use a "default" resampling filter defined at compile time.

To override the + memory allocation, before the implementation #include, add a: + + #define STBIR_MALLOC(size,user_data) ... + #define STBIR_FREE(ptr,user_data) ... + + Each resize makes exactly one call to malloc/free (unless you use the + extended API where you can do one allocation for many resizes). Under + address sanitizer, we do separate allocations to find overread/writes. + + PERFORMANCE + This library was written with an emphasis on performance. When testing + stb_image_resize with RGBA, the fastest mode is STBIR_4CHANNEL with + STBIR_TYPE_UINT8 pixels and CLAMPed edges (which is what many other resize + libs do by default). Also, make sure SIMD is turned on of course (default + for 64-bit targets). Avoid WRAP edge mode if you want the fastest speed. + + This library also comes with profiling built-in. If you define STBIR_PROFILE, + you can use the advanced API and get low-level profiling information by + calling stbir_resize_extended_profile_info() or stbir_resize_split_profile_info() + after a resize. + + SIMD + Most of the routines have optimized SSE2, AVX, NEON and WASM versions. + + On Microsoft compilers, we automatically turn on SIMD for 64-bit x64 and + ARM; for 32-bit x86 and ARM, you select SIMD mode by defining STBIR_SSE2 or + STBIR_NEON. For AVX and AVX2, we auto-select it by detecting the /arch:AVX + or /arch:AVX2 switches. You can also always manually turn SSE2, AVX or AVX2 + support on by defining STBIR_SSE2, STBIR_AVX or STBIR_AVX2. + + On Linux, SSE2 and Neon is on by default for 64-bit x64 or ARM64. For 32-bit, + we select x86 SIMD mode by whether you have -msse2, -mavx or -mavx2 enabled + on the command line. For 32-bit ARM, you must pass -mfpu=neon-vfpv4 for both + clang and GCC, but GCC also requires an additional -mfp16-format=ieee to + automatically enable NEON. + + On x86 platforms, you can also define STBIR_FP16C to turn on FP16C instructions + for converting back and forth to half-floats. This is autoselected when we + are using AVX2. Clang and GCC also require the -mf16c switch. ARM always uses + the built-in half float hardware NEON instructions. + + You can also tell us to use multiply-add instructions with STBIR_USE_FMA. + Because x86 doesn't always have fma, we turn it off by default to maintain + determinism across all platforms. If you don't care about non-FMA determinism + and are willing to restrict yourself to more recent x86 CPUs (around the AVX + timeframe), then fma will give you around a 15% speedup. + + You can force off SIMD in all cases by defining STBIR_NO_SIMD. You can turn + off AVX or AVX2 specifically with STBIR_NO_AVX or STBIR_NO_AVX2. AVX is 10% + to 40% faster, and AVX2 is generally another 12%. + + ALPHA CHANNEL + Most of the resizing functions provide the ability to control how the alpha + channel of an image is processed. + + When alpha represents transparency, it is important that when combining + colors with filtering, the pixels should not be treated equally; they + should use a weighted average based on their alpha values. For example, + if a pixel is 1% opaque bright green and another pixel is 99% opaque + black and you average them, the average will be 50% opaque, but the + unweighted average and will be a middling green color, while the weighted + average will be nearly black. This means the unweighted version introduced + green energy that didn't exist in the source image. + + (If you want to know why this makes sense, you can work out the math for + the following: consider what happens if you alpha composite a source image + over a fixed color and then average the output, vs. if you average the + source image pixels and then composite that over the same fixed color. + Only the weighted average produces the same result as the ground truth + composite-then-average result.) + + Therefore, it is in general best to "alpha weight" the pixels when applying + filters to them. This essentially means multiplying the colors by the alpha + values before combining them, and then dividing by the alpha value at the + end. + + The computer graphics industry introduced a technique called "premultiplied + alpha" or "associated alpha" in which image colors are stored in image files + already multiplied by their alpha. This saves some math when compositing, + and also avoids the need to divide by the alpha at the end (which is quite + inefficient). However, while premultiplied alpha is common in the movie CGI + industry, it is not commonplace in other industries like videogames, and most + consumer file formats are generally expected to contain not-premultiplied + colors. For example, Photoshop saves PNG files "unpremultiplied", and web + browsers like Chrome and Firefox expect PNG images to be unpremultiplied. + + Note that there are three possibilities that might describe your image + and resize expectation: + + 1. images are not premultiplied, alpha weighting is desired + 2. images are not premultiplied, alpha weighting is not desired + 3. images are premultiplied + + Both case #2 and case #3 require the exact same math: no alpha weighting + should be applied or removed. Only case 1 requires extra math operations; + the other two cases can be handled identically. + + stb_image_resize expects case #1 by default, applying alpha weighting to + images, expecting the input images to be unpremultiplied. This is what the + COLOR+ALPHA buffer types tell the resizer to do. + + When you use the pixel layouts STBIR_RGBA, STBIR_BGRA, STBIR_ARGB, + STBIR_ABGR, STBIR_RX, or STBIR_XR you are telling us that the pixels are + non-premultiplied. In these cases, the resizer will alpha weight the colors + (effectively creating the premultiplied image), do the filtering, and then + convert back to non-premult on exit. + + When you use the pixel layouts STBIR_RGBA_PM, STBIR_RGBA_PM, STBIR_RGBA_PM, + STBIR_RGBA_PM, STBIR_RX_PM or STBIR_XR_PM, you are telling that the pixels + ARE premultiplied. In this case, the resizer doesn't have to do the + premultipling - it can filter directly on the input. This about twice as + fast as the non-premultiplied case, so it's the right option if your data is + already setup correctly. + + When you use the pixel layout STBIR_4CHANNEL or STBIR_2CHANNEL, you are + telling us that there is no channel that represents transparency; it may be + RGB and some unrelated fourth channel that has been stored in the alpha + channel, but it is actually not alpha. No special processing will be + performed. + + The difference between the generic 4 or 2 channel layouts, and the + specialized _PM versions is with the _PM versions you are telling us that + the data *is* alpha, just don't premultiply it. That's important when + using SRGB pixel formats, we need to know where the alpha is, because + it is converted linearly (rather than with the SRGB converters). + + Because alpha weighting produces the same effect as premultiplying, you + even have the option with non-premultiplied inputs to let the resizer + produce a premultiplied output. Because the intially computed alpha-weighted + output image is effectively premultiplied, this is actually more performant + than the normal path which un-premultiplies the output image as a final step. + + Finally, when converting both in and out of non-premulitplied space (for + example, when using STBIR_RGBA), we go to somewhat heroic measures to + ensure that areas with zero alpha value pixels get something reasonable + in the RGB values. If you don't care about the RGB values of zero alpha + pixels, you can call the stbir_set_non_pm_alpha_speed_over_quality() + function - this runs a premultiplied resize about 25% faster. That said, + when you really care about speed, using premultiplied pixels for both in + and out (STBIR_RGBA_PM, etc) much faster than both of these premultiplied + options. + + PIXEL LAYOUT CONVERSION + The resizer can convert from some pixel layouts to others. When using the + stbir_set_pixel_layouts(), you can, for example, specify STBIR_RGBA + on input, and STBIR_ARGB on output, and it will re-organize the channels + during the resize. Currently, you can only convert between two pixel + layouts with the same number of channels. + + DETERMINISM + We commit to being deterministic (from x64 to ARM to scalar to SIMD, etc). + This requires compiling with fast-math off (using at least /fp:precise). + Also, you must turn off fp-contracting (which turns mult+adds into fmas)! + We attempt to do this with pragmas, but with Clang, you usually want to add + -ffp-contract=off to the command line as well. + + For 32-bit x86, you must use SSE and SSE2 codegen for determinism. That is, + if the scalar x87 unit gets used at all, we immediately lose determinism. + On Microsoft Visual Studio 2008 and earlier, from what we can tell there is + no way to be deterministic in 32-bit x86 (some x87 always leaks in, even + with fp:strict). On 32-bit x86 GCC, determinism requires both -msse2 and + -fpmath=sse. + + Note that we will not be deterministic with float data containing NaNs - + the NaNs will propagate differently on different SIMD and platforms. + + If you turn on STBIR_USE_FMA, then we will be deterministic with other + fma targets, but we will differ from non-fma targets (this is unavoidable, + because a fma isn't simply an add with a mult - it also introduces a + rounding difference compared to non-fma instruction sequences. + + FLOAT PIXEL FORMAT RANGE + Any range of values can be used for the non-alpha float data that you pass + in (0 to 1, -1 to 1, whatever). However, if you are inputting float values + but *outputting* bytes or shorts, you must use a range of 0 to 1 so that we + scale back properly. The alpha channel must also be 0 to 1 for any format + that does premultiplication prior to resizing. + + Note also that with float output, using filters with negative lobes, the + output filtered values might go slightly out of range. You can define + STBIR_FLOAT_LOW_CLAMP and/or STBIR_FLOAT_HIGH_CLAMP to specify the range + to clamp to on output, if that's important. + + MAX/MIN SCALE FACTORS + The input pixel resolutions are in integers, and we do the internal pointer + resolution in size_t sized integers. However, the scale ratio from input + resolution to output resolution is calculated in float form. This means + the effective possible scale ratio is limited to 24 bits (or 16 million + to 1). As you get close to the size of the float resolution (again, 16 + million pixels wide or high), you might start seeing float inaccuracy + issues in general in the pipeline. If you have to do extreme resizes, + you can usually do this is multiple stages (using float intermediate + buffers). + + FLIPPED IMAGES + Stride is just the delta from one scanline to the next. This means you can + use a negative stride to handle inverted images (point to the final + scanline and use a negative stride). You can invert the input or output, + using negative strides. + + DEFAULT FILTERS + For functions which don't provide explicit control over what filters to + use, you can change the compile-time defaults with: + + #define STBIR_DEFAULT_FILTER_UPSAMPLE STBIR_FILTER_something + #define STBIR_DEFAULT_FILTER_DOWNSAMPLE STBIR_FILTER_something + + See stbir_filter in the header-file section for the list of filters. + + NEW FILTERS + A number of 1D filter kernels are supplied. For a list of supported + filters, see the stbir_filter enum. You can install your own filters by + using the stbir_set_filter_callbacks function. + + PROGRESS + For interactive use with slow resize operations, you can use the the + scanline callbacks in the extended API. It would have to be a *very* large + image resample to need progress though - we're very fast. + + CEIL and FLOOR + In scalar mode, the only functions we use from math.h are ceilf and floorf, + but if you have your own versions, you can define the STBIR_CEILF(v) and + STBIR_FLOORF(v) macros and we'll use them instead.

This object may be passed into a lease request to + indicate the client would like to lease that connector, see + wp_drm_lease_request_v1.request_connector for details.
