Before I go into -detail about the major changes I would like to apologize. I know it's annoying dealing with breaking API changes, but I think -it's best to get these changes out of the way now while the library is still relatively young and unknown. - -There's been a lot of refactoring with this release so there's a good chance a few bugs have been introduced. I apologize in -advance for this. You may want to hold off on upgrading for the short term if you're worried. If mini_al v0.8.14 works for -you, and you don't need full-duplex support, you can avoid upgrading (though you won't be getting future bug fixes). +Version 0.10 includes major API changes and refactoring, mostly concerned with the data conversion system. Data conversion is performed internally to convert +audio data between the format requested when initializing the `ma_device` object and the format of the internal device used by the backend. The same applies +to the `ma_decoder` object. The previous design has several design flaws and missing features which necessitated a complete redesign. -Rebranding to "miniaudio" -------------------------- -The decision was made to rename mini_al to miniaudio. Don't worry, it's the same project. The reason for this is simple: +Changes to Data Conversion +-------------------------- +The previous data conversion system used callbacks to deliver input data for conversion. This design works well in some specific situations, but in other +situations it has some major readability and maintenance issues. The decision was made to replace this with a more iterative approach where you just pass in a +pointer to the input data directly rather than dealing with a callback. -1) Having the word "audio" in the title makes it immediately clear that the library is related to audio; and -2) I don't like the look of the underscore. +The following are the data conversion APIs that have been removed and their replacements: -This rebrand has necessitated a change in namespace from "mal" to "ma". I know this is annoying, and I apologize, but it's -better to get this out of the road now rather than later. Also, since there are necessary API changes for full-duplex support -I think it's better to just get the namespace change over and done with at the same time as the full-duplex changes. I'm hoping -this will be the last of the major API changes. Fingers crossed! + - ma_format_converter -> ma_convert_pcm_frames_format() + - ma_channel_router -> ma_channel_converter + - ma_src -> ma_resampler + - ma_pcm_converter -> ma_data_converter -The implementation define is now "#define MINIAUDIO_IMPLEMENTATION". You can also use "#define MA_IMPLEMENTATION" if that's -your preference. +The previous conversion APIs accepted a callback in their configs. There are no longer any callbacks to deal with. Instead you just pass the data into the +`*_process_pcm_frames()` function as a pointer to a buffer. + +The simplest aspect of data conversion is sample format conversion. To convert between two formats, just call `ma_convert_pcm_frames_format()`. Channel +conversion is also simple which you can do with `ma_channel_router` via `ma_channel_router_process_pcm_frames(). + +Resampling is more complicated because the number of output frames that are processed is different to the number of input frames that are consumed. When you +call `ma_resampler_process_pcm_frames()` you need to pass in the number of input frames available for processing and the number of output frames you want to +output. Upon returning they will receive the number of input frames that were consumed and the number of output frames that were generated. + +The `ma_data_converter` API is a wrapper around format, channel and sample rate conversion and handles all of the data conversion you'll need which probably +makes it the best option if you need to do data conversion. + +In addition to changes to the API design, a few other changes have been made to the data conversion pipeline: + + - The sinc resampler has been removed. This was completely broken and never actually worked properly. + - The linear resampler can now uses low-pass filtering to remove aliasing. The quality of the low-pass filter can be controlled via the resampler config with + the `lpfCount` option, which has a maximum value of MA_MAX_RESAMPLER_LPF_FILTERS. + - Data conversion now supports s16 natively which runs through a fixed point pipeline. Previously everything needed to be converted to floating point before + processing, whereas now both s16 and f32 are natively supported. Other formats still require conversion to either s16 or f32 prior to processing, however + `ma_data_converter` will handle this for you. -Full-Duplex Support -------------------- -The major feature added to version 0.9 is full-duplex. This has necessitated a few API changes. +Custom Memory Allocators +------------------------ +miniaudio has always supported macro level customization for memory allocation via MA_MALLOC, MA_REALLOC and MA_FREE, however some scenarios require more +flexibility by allowing a user data pointer to be passed to the custom allocation routines. Support for this has been added to version 0.10 via the +`ma_allocation_callbacks` structure. Anything making use of heap allocations has been updated to accept this new structure. -1) The data callback has now changed. Previously there was one type of callback for playback and another for capture. I wanted - to avoid a third callback just for full-duplex so the decision was made to break this API and unify the callbacks. Now, - there is just one callback which is the same for all three modes (playback, capture, duplex). The new callback looks like - the following: +The `ma_context_config` structure has been updated with a new member called `allocationCallbacks`. Leaving this set to it's defaults returned by +`ma_context_config_init()` will cause it to use MA_MALLOC, MA_REALLOC and MA_FREE. Likewise, The `ma_decoder_config` structure has been updated in the same +way, and leaving everything as-is after `ma_decoder_config_init()` will cause it to use the same defaults. - void data_callback(ma_device* pDevice, void* pOutput, const void* pInput, ma_uint32 frameCount); +The following APIs have been updated to take a pointer to a `ma_allocation_callbacks` object. Setting this parameter to NULL will cause it to use defaults. +Otherwise they will use the relevant callback in the structure. - This callback allows you to move data straight out of the input buffer and into the output buffer in full-duplex mode. In - playback-only mode, pInput will be null. Likewise, pOutput will be null in capture-only mode. The sample count is no longer - returned from the callback since it's not necessary for miniaudio anymore. + - ma_malloc() + - ma_realloc() + - ma_free() + - ma_aligned_malloc() + - ma_aligned_free() + - ma_rb_init() / ma_rb_init_ex() + - ma_pcm_rb_init() / ma_pcm_rb_init_ex() -2) The device config needed to change in order to support full-duplex. Full-duplex requires the ability to allow the client - to choose a different PCM format for the playback and capture sides. The old ma_device_config object simply did not allow - this and needed to change. With these changes you now specify the device ID, format, channels, channel map and share mode - on a per-playback and per-capture basis (see example below). The sample rate must be the same for playback and capture. +Note that you can continue to use MA_MALLOC, MA_REALLOC and MA_FREE as per normal. These will continue to be used by default if you do not specify custom +allocation callbacks. - Since the device config API has changed I have also decided to take the opportunity to simplify device initialization. Now, - the device ID, device type and callback user data are set in the config. ma_device_init() is now simplified down to taking - just the context, device config and a pointer to the device object being initialized. The rationale for this change is that - it just makes more sense to me that these are set as part of the config like everything else. - Example device initialization: +Buffer and Period Configuration Changes +--------------------------------------- +The way in which the size of the internal buffer and periods are specified in the device configuration have changed. In previous versions, the config variables +`bufferSizeInFrames` and `bufferSizeInMilliseconds` defined the size of the entire buffer, with the size of a period being the size of this variable divided by +the period count. This became confusing because people would expect the value of `bufferSizeInFrames` or `bufferSizeInMilliseconds` to independantly determine +latency, when in fact it was that value divided by the period count that determined it. These variables have been removed and replaced with new ones called +`periodSizeInFrames` and `periodSizeInMilliseconds`. - ma_device_config config = ma_device_config_init(ma_device_type_duplex); // Or ma_device_type_playback or ma_device_type_capture. - config.playback.pDeviceID = &myPlaybackDeviceID; // Or NULL for the default playback device. - config.playback.format = ma_format_f32; - config.playback.channels = 2; - config.capture.pDeviceID = &myCaptureDeviceID; // Or NULL for the default capture device. - config.capture.format = ma_format_s16; - config.capture.channels = 1; - config.sampleRate = 44100; - config.dataCallback = data_callback; - config.pUserData = &myUserData; +These new configuration variables work in the same way as their predecessors in that if one is set to 0, the other will be used, but the main difference is +that you now set these to you desired latency rather than the size of the entire buffer. The benefit of this is that it's much easier and less confusing to +configure latency. - result = ma_device_init(&myContext, &config, &device); - if (result != MA_SUCCESS) { - ... handle error ... - } +The following unused APIs have been removed: - Note that the "onDataCallback" member of ma_device_config has been renamed to "dataCallback". Also, "onStopCallback" has - been renamed to "stopCallback". + ma_get_default_buffer_size_in_milliseconds() + ma_get_default_buffer_size_in_frames() -This is the first pass for full-duplex and there is a known bug. You will hear crackling on the following backends when sample -rate conversion is required for the playback device: - - Core Audio - - JACK - - AAudio - - OpenSL - - WebAudio +The following macros have been removed: -In addition to the above, not all platforms have been absolutely thoroughly tested simply because I lack the hardware for such -thorough testing. If you experience a bug, an issue report on GitHub or an email would be greatly appreciated (and a sample -program that reproduces the issue if possible). + MA_BASE_BUFFER_SIZE_IN_MILLISECONDS_LOW_LATENCY + MA_BASE_BUFFER_SIZE_IN_MILLISECONDS_CONSERVATIVE Other API Changes ----------------- -In addition to the above, the following API changes have been made: +Other less major API changes have also been made in version 0.10. -- The log callback is no longer passed to ma_context_config_init(). Instead you need to set it manually after initialization. -- The onLogCallback member of ma_context_config has been renamed to "logCallback". -- The log callback now takes a logLevel parameter. The new callback looks like: void log_callback(ma_context* pContext, ma_device* pDevice, ma_uint32 logLevel, const char* message) - - You can use ma_log_level_to_string() to convert the logLevel to human readable text if you want to log it. -- Some APIs have been renamed: - - mal_decoder_read() -> ma_decoder_read_pcm_frames() - - mal_decoder_seek_to_frame() -> ma_decoder_seek_to_pcm_frame() - - mal_sine_wave_read() -> ma_sine_wave_read_f32() - - mal_sine_wave_read_ex() -> ma_sine_wave_read_f32_ex() -- Some APIs have been removed: - - mal_device_get_buffer_size_in_bytes() - - mal_device_set_recv_callback() - - mal_device_set_send_callback() - - mal_src_set_input_sample_rate() - - mal_src_set_output_sample_rate() -- Error codes have been rearranged. If you're a binding maintainer you will need to update. -- The ma_backend enums have been rearranged to priority order. The rationale for this is to simplify automatic backend selection - and to make it easier to see the priority. If you're a binding maintainer you will need to update. -- ma_dsp has been renamed to ma_pcm_converter. The rationale for this change is that I'm expecting "ma_dsp" to conflict with - some future planned high-level APIs. -- For functions that take a pointer/count combo, such as ma_decoder_read_pcm_frames(), the parameter order has changed so that - the pointer comes before the count. The rationale for this is to keep it consistent with things like memcpy(). +`ma_device_set_stop_callback()` has been removed. You now must set the stop callback via the device config just like the data callback. + +The `ma_sine_wave` API has been replaced with a more general API called `ma_waveform`. This supports generation of different types of waveforms, including +sine, square, triangle and sawtooth. Use `ma_waveform_init()` in place of `ma_sine_wave_init()` to initialize the waveform object. This takes the same +parameters, except an additional `ma_waveform_type` value which you would set to `ma_waveform_type_sine`. Use `ma_waveform_read_pcm_frames()` in place of +`ma_sine_wave_read_f32()` and `ma_sine_wave_read_f32_ex()`. + +`ma_convert_frames()` and `ma_convert_frames_ex()` have been changed. Both of these functions now take a new parameter called `frameCountOut` which specifies +the size of the output buffer in PCM frames. This has been added for safety. In addition to this, the parameters for `ma_convert_frames_ex()` have changed to +take a pointer to a `ma_data_converter_config` object to specify the input and output formats to convert between. This was done to make it make it more +flexible, to prevent the parameter list getting too long, and to prevent API breakage whenever a new conversion property is added. + +`ma_calculate_frame_count_after_src()` has been renamed to `ma_calculate_frame_count_after_resampling()` for consistency with the new `ma_resampler` API. + + +Biquad and Low-Pass Filters +--------------------------- +A generic biquad filter has been added. This is used via the `ma_biquad` API. The biquad filter is used as the basis for the low-pass filter. The biquad filter +supports 32-bit floating point samples which runs on a floating point pipeline and 16-bit signed integer samples which runs on a 32-bit fixed point pipeline. +Both formats use transposed direct form 2. + +The low-pass filter is just a biquad filter. By itself it's a second order low-pass filter, but it can be extended to higher orders by chaining low-pass +filters together. Low-pass filtering is achieved via the `ma_lpf` API. Since the low-pass filter is just a biquad filter, it supports both 32-bit floating +point and 16-bit signed integer formats. + + +Sine, Square, Triangle and Sawtooth Waveforms +--------------------------------------------- +Previously miniaudio supported only sine wave generation. This has now been generalized to support sine, square, triangle and sawtooth waveforms. The old +`ma_sine_wave` API has been removed and replaced with the `ma_waveform` API. Use `ma_waveform_init()` to initialize the waveform. Here you specify tyhe type of +waveform you want to generated. You then read data using `ma_waveform_read_pcm_frames()`. Miscellaneous Changes --------------------- -The following miscellaneous changes have also been made. +Internal functions have all been made static where possible. If you get warnings about unused functions, please submit a bug report. -- The AAudio backend has been added for Android 8 and above. This is Android's new "High-Performance Audio" API. (For the - record, this is one of the nicest audio APIs out there, just behind the BSD audio APIs). -- The WebAudio backend has been added. This is based on ScriptProcessorNode. This removes the need for SDL. -- The SDL and OpenAL backends have been removed. These were originally implemented to add support for platforms for which miniaudio - was not explicitly supported. These are no longer needed and have therefore been removed. -- Device initialization now fails if the requested share mode is not supported. If you ask for exclusive mode, you either get an - exclusive mode device, or an error. The rationale for this change is to give the client more control over how to handle cases - when the desired shared mode is unavailable. -- A lock-free ring buffer API has been added. There are two varients of this. "ma_rb" operates on bytes, whereas "ma_pcm_rb" - operates on PCM frames. -- The library is now licensed as a choice of Public Domain (Unlicense) _or_ MIT-0 (No Attribution) which is the same as MIT, but - removes the attribution requirement. The rationale for this is to support countries that don't recognize public domain. +The `ma_device` structure is no longer defined as being aligned to MA_SIMD_ALIGNMENT. This resulted in a possible crash when allocating a `ma_device` object on +the heap, but not aligning it to MA_SIMD_ALIGNMENT. This crash would happen due to the compiler seeing the alignment specified on the structure and assuming it +was always aligned as such and thinking it was safe to emit alignment-dependant SIMD instructions. Since miniaudio's philosophy is for things to just work, +this has been removed from all structures. */ + /* -ABOUT -===== -miniaudio is a single file library for audio playback and capture. It's written in C (compilable as -C++) and released into the public domain. +Introduction +============ +miniaudio is a single file library for audio playback and capture. To use it, do the following in one .c file: -Supported Backends: - - WASAPI - - DirectSound - - WinMM - - Core Audio (Apple) - - ALSA - - PulseAudio - - JACK - - sndio (OpenBSD) - - audio(4) (NetBSD and OpenBSD) - - OSS (FreeBSD) - - AAudio (Android 8.0+) - - OpenSL|ES (Android only) - - Web Audio (Emscripten) - - Null (Silence) + ```c + #define MINIAUDIO_IMPLEMENTATION + #include "miniaudio.h + ``` -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 +You can #include miniaudio.h in other parts of the program just like any other header. + +miniaudio 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. + } + + ... + + ma_device_config config = ma_device_config_init(ma_device_type_playback); + config.playback.format = MY_FORMAT; + config.playback.channels = MY_CHANNEL_COUNT; + config.sampleRate = MY_SAMPLE_RATE; + config.dataCallback = data_callback; + config.pUserData = pMyCustomData; // Can be accessed from the device object (device.pUserData). + + ma_device device; + if (ma_device_init(NULL, &config, &device) != MA_SUCCESS) { + ... An error occurred ... + } + + ma_device_start(&device); // The device is sleeping by default so you'll need to start it manually. + + ... + + ma_device_uninit(&device); // This will stop the device so no need to do that manually. + ``` + +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: + + 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_CHANNELS; + ``` + +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: + + ``` + 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 call 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* pPlaybackDeviceInfos; + ma_uint32 playbackDeviceCount; + ma_device_info* pCaptureDeviceInfos; + ma_uint32 captureDeviceCount; + if (ma_context_get_devices(&context, &pPlaybackDeviceInfos, &playbackDeviceCount, &pCaptureDeviceInfos, &captureDeviceCount) != MA_SUCCESS) { + // Error. + } + + // Loop over the 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 < playbackDeviceCount; iDevice += 1) { + printf("%d - %s\n", iDevice, pPlaybackDeviceInfos[iDevice].name); + } + + ma_device_config config = ma_device_config_init(ma_device_type_playback); + config.playback.pDeviceID = &pPlaybackDeviceInfos[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 paramter. 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. -USAGE -===== -miniaudio is a single-file library.

To enable a decoder you must #include the header of the relevant backend library before the +implementation of miniaudio. You can find copies of these in the "extras" folder in the miniaudio repository (https://github.com/dr-soft/miniaudio). + +The table below are the supported decoding backends: + + |--------|-----------------| + | Type | Backend Library | + |--------|-----------------| + | WAV | dr_wav.h | + | FLAC | dr_flac.h | + | MP3 | dr_mp3.h | + | Vorbis | stb_vorbis.c | + |--------|-----------------| + +The code below is an example of how to enable decoding backends: + + ```c + #include "dr_flac.h" // Enables FLAC decoding. + #include "dr_mp3.h" // Enables MP3 decoding. + #include "dr_wav.h" // Enables WAV decoding. + + #define MINIAUDIO_IMPLEMENTATION + #include "miniaudio.h" + ``` + +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: + + ```c + ma_uint64 framesRead = ma_decoder_read_pcm_frames(pDecoder, pFrames, framesToRead); + ``` + +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. + } + ``` + +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 the `_wav`, `_mp3`, etc. varients of the aforementioned initialization APIs: + + ```c + ma_decoder_init_wav() + ma_decoder_init_mp3() + ma_decoder_init_memory_wav() + ma_decoder_init_memory_mp3() + ma_decoder_init_file_wav() + ma_decoder_init_file_mp3() + etc. + ``` + +The `ma_decoder_init_file()` API will try using the file extension to determine which decoding backend to prefer. + + + +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. + +Dithering +--------- +Dithering can be set using ditherMode parmater. + +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. + + + +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, 1, NULL, 2, NULL, ma_channel_mix_mode_default, NULL); + result = ma_channel_converter_init(&config, &converter); + if (result != MA_SUCCESS) { + // Error. + } + ``` + +To process 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 accomodate the new PCM frames. + +The only formats supported are `ma_format_s16` and `ma_format_f32`. If you need another format you need to convert your data manually which you can do with +`ma_pcm_convert()`, etc. + +Input and output PCM frames are always interleaved. Deinterleaved layouts are not supported. + + +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 with 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_get_standard_channel_map()`.

This | + | | is equivalent to the same | + | | mapping as the device. | + |---------------|------------------------------| + + + +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, &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 supports multiple algorithms: + + |-----------|------------------------------| + | Algorithm | Enum Token | + |-----------|------------------------------| + | Linear | ma_resample_algorithm_linear | + | Speex | ma_resample_algorithm_speex | + |-----------|------------------------------| + +Because Speex is not public domain it is strictly opt-in and the code is stored in separate files. if you opt-in to the Speex backend you will need to consider +it's license, the text of which can be found in it's source files in "extras/speex_resampler". Details on how to opt-in to the Speex resampler is explained in +the Speex Resampler section below. + +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()`. + + +Resampling Algorithms +--------------------- +The choice of resampling algorithm depends on your situation and requirements. The linear resampler is the most efficient and has the least amount of latency, +but at the expense of poorer quality. The Speex resampler is higher quality, but slower with more latency. It also performs several heap applications +internally for memory management. + + +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 second order low-pass filter will be applied. To improve quality you can chain low-pass filters together, up to a maximum of `MA_MAX_RESAMPLER_LPF_FILTERS`. +This comes at the expense of increased computational cost and latency. You can also disable filtering altogether by setting the filter count to 0. The filter +count is controlled with the `lpfCount` config variable. + +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). This +can be controlled with the `lpfNyquistFactor` config variable. This defaults to 1, and should be in the range of 0..1, although a value of 0 does not make +sense and should be avoided. A value of 1 will use the Nyquist Frequency as the cutoff. A value of 0.5 will use half the Nyquist Frequency as the cutoff, etc. +Values less than 1 will result in more washed out sound due to more of the higher frequencies being removed. This config variable has no impact on performance +and is a purely perceptual configuration. + +The API for the linear resampler is the same as the main resampler API, only it's called `ma_linear_resampler`. + + +Speex Resampling +---------------- +The Speex resampler is made up of third party code which is released under the BSD license. Because it is licensed differently to miniaudio, which is public +domain, it is strictly opt-in and all of it's code is stored in separate files. If you opt-in to the Speex resampler you must consider the license text in it's +source files. To opt-in, you must first #include the following file before the implementation of miniaudio.h: + + #include "extras/speex_resampler/ma_speex_resampler.h" + +Both the header and implementation is contained within the same file. To implementation can be included in your program like so: + + #define MINIAUDIO_SPEEX_RESAMPLER_IMPLEMENTATION + #include "extras/speex_resampler/ma_speex_resampler.h" + +Note that even if you opt-in to the Speex backend, miniaudio won't use it unless you explicitly ask for it in the respective config of the object you are +initializing. If you try to use the Speex resampler without opting in, initialization of the `ma_resampler` object will fail with `MA_NO_BACKEND`. + +The only configuration option to consider with the Speex resampler is the `speex.quality` config variable. This is a value between 0 and 10, with 0 being +the worst/fastest and 10 being the best/slowest. The default value is 3. + + + + +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, &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_get_standard_channel_map(ma_standard_channel_map_flac, config.channelCountIn, config.channelMapIn); + config.resampling.linear.lpfCount = MA_MAX_RESAMPLER_LPF_FILTERS; + ``` + +Do the following to uninitialize the data converter: + + ```c + ma_data_converter_uninit(&converter); + ``` + +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. + +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, 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()`. + + + + +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, &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 or whatnot. 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. + + + +Low-Pass, High-Pass and Band-Pass Filtering +=========================================== +Low-pass, high-pass and band-pass filtering is achieved with the `ma_lpf`, `ma_hpf` and `ma_bpf` APIs respective. Low-pass filter example: + + ```c + ma_lpf_config config = ma_lpf_config_init(ma_format_f32, channels, sampleRate, cutoffFrequency); + 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); + ``` + +These filters are implemented as a biquad filter. If you need to increase the filter order, simply chain multiple filters together. + + ```c + for (iFilter = 0; iFilter < filterCount; iFilter += 1) { + ma_lpf_process_pcm_frames(&lpf[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 maintaing smooth transitions. Note that changing the format or channel +count after initialization is invalid and will result in an error. + +The example code above is for low-pass filters, but the same applies for high-pass and band-pass filters, only you should use the `ma_hpf` and `ma_bpf` APIs +instead. + + + +Waveforms +========= +miniaudio supports generation of sine, square, triangle and sawtooth waveforms. This is achieved with the `ma_waveform` API. Example: + + ```c + ma_waveform waveform; + ma_result result = ma_waveform_init(ma_waveform_type_sine, amplitude, frequency, sampleRate, &waveform); + if (result != MA_SUCCESS) { + // Error. + } + + ... + + ma_waveform_read_pcm_frames(&waveform, pOutput, frameCount, FORMAT, CHANNELS); + ``` + +The amplitude, frequency and sample rate can be changed dynamically with `ma_waveform_set_amplitude()`, `ma_waveform_set_frequency()` and +`ma_waveform_set_sample_rate()` respectively. + + + +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 varient 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. + +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 sample, only you will use the `ma_rb` +functions instead of `ma_pcm_rb` and instead of frame counts you'll 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 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. + + + +Backends +======== +The following backends are supported by miniaudio. + + |-------------|-----------------------|--------------------------------------------------------| + | Name | Enum Name | Supported Operating Systems | + |-------------|-----------------------|--------------------------------------------------------| + | WASAPI | ma_backend_wasapi | Windows Vista+ | + | DirectSound | ma_backend_dsound | Windows XP+ | + | WinMM | ma_backend_winmm | Windows XP+ (may work on older versions, but untested) | + | Core Audio | ma_backend_coreaudio | macOS, iOS | + | ALSA | ma_backend_alsa | Linux | + | PulseAudio | ma_backend_pulseaudio | Cross Platform (disabled on Windows, BSD and Android) | + | JACK | ma_backend_jack | Cross Platform (disabled on BSD and Android) | + | sndio | ma_backend_sndio | OpenBSD | + | audio(4) | ma_backend_audio4 | NetBSD, OpenBSD | + | OSS | ma_backend_oss | FreeBSD | + | AAudio | ma_backend_aaudio | Android 8+ | + | OpenSL|ES | ma_backend_opensl | Android (API level 16+) | + | Web Audio | ma_backend_webaudio | Web (via Emscripten) | + | Null | ma_backend_null | Cross Platform (not used on Web) | + |-------------|-----------------------|--------------------------------------------------------| + +Some backends have some nuance details you may want to be aware of. + +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 lower quality internal resampler being used + instead which will in turn enable the use of low-latency shared mode. + +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. + +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. + +UWP +--- +- UWP only supports default playback and capture devices. +- UWP requires the Microphone capability to be enabled in the application's manifest (Package.appxmanifest): + + ... + + + + + +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. + + + +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. +- The contents of the output buffer passed into the data callback will always be pre-initialized to zero unless the noPreZeroedOutputBuffer config variable in + ma_device_config is set to true, in which case it'll be undefined which will require you to write something to the entire buffer. +- By default miniaudio will automatically clip samples. This only applies when the playback sample format is configured as ma_format_f32. If you are doing + clipping yourself, you can disable this overhead by setting noClip to true in the device config. +- 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. +- Note that GCC and Clang requires "-msse2", "-mavx2", etc. for SIMD optimizations. */ #ifndef miniaudio_h @@ -450,13 +1190,16 @@ Throughout miniaudio you will see references to different sample formats: extern "C" { #endif -#if defined(_MSC_VER) +#if defined(_MSC_VER) && !defined(__clang__) #pragma warning(push) #pragma warning(disable:4201) /* nonstandard extension used: nameless struct/union */ #pragma warning(disable:4324) /* structure was padded due to alignment specifier */ #else #pragma GCC diagnostic push #pragma GCC diagnostic ignored "-Wpedantic" /* For ISO C99 doesn't support unnamed structs/unions [-Wpedantic] */ + #if defined(__clang__) + #pragma GCC diagnostic ignored "-Wc11-extensions" /* anonymous unions are a C11 extension */ + #endif #endif /* Platform/backend detection. */ @@ -470,6 +1213,7 @@ extern "C" { #else #define MA_POSIX #include /* Unfortunate #include, but needed for pthread_t, pthread_mutex_t and pthread_cond_t types. */ + #include #ifdef __unix__ #define MA_UNIX @@ -498,6 +1242,7 @@ extern "C" { #if defined(__clang__) #pragma GCC diagnostic push #pragma GCC diagnostic ignored "-Wlanguage-extension-token" + #pragma GCC diagnostic ignored "-Wlong-long" #pragma GCC diagnostic ignored "-Wc++11-long-long" #endif typedef signed __int8 ma_int8; @@ -570,13 +1315,22 @@ typedef ma_uint16 wchar_t; #ifdef _MSC_VER -#define MA_INLINE __forceinline + #define MA_INLINE __forceinline +#elif defined(__GNUC__) + /* + I've had a bug report where GCC is emitting warnings about functions possibly not being inlineable.

To do this you just pass in the same channel -count for both the input and output with channel maps that contain the same channels (in a different order). - -Channel Conversion ------------------- -The channel router can also convert from one channel count to another, such as converting a 5.1 stream to stero. When changing the channel count, the -router will first perform a 1:1 mapping of channel positions that are present in both the input and output channel maps. The second thing it will do -is distribute the input mono channel (if any) across all output channels, excluding any None and LFE channels. If there is an output mono channel, all -input channels will be averaged, excluding any None and LFE channels. - -The last case to consider is when a channel position in the input channel map is not present in the output channel map, and vice versa. In this case the -channel router will perform a blend of other related channels to produce an audible channel. There are several blending modes. - 1) Simple - Unmatched channels are silenced. - 2) Planar Blending - Channels are blended based on a set of planes that each speaker emits audio from. - -Rectangular / Planar Blending ------------------------------ -In this mode, channel positions are associated with a set of planes where the channel conceptually emits audio from. An example is the front/left speaker. -This speaker is positioned to the front of the listener, so you can think of it as emitting audio from the front plane. It is also positioned to the left -of the listener so you can think of it as also emitting audio from the left plane. Now consider the (unrealistic) situation where the input channel map -contains only the front/left channel position, but the output channel map contains both the front/left and front/center channel. When deciding on the audio -data to send to the front/center speaker (which has no 1:1 mapping with an input channel) we need to use some logic based on our available input channel -positions. - -As mentioned earlier, our front/left speaker is, conceptually speaking, emitting audio from the front _and_ the left planes. Similarly, the front/center -speaker is emitting audio from _only_ the front plane. What these two channels have in common is that they are both emitting audio from the front plane. -Thus, it makes sense that the front/center speaker should receive some contribution from the front/left channel. How much contribution depends on their -planar relationship (thus the name of this blending technique). - -Because the front/left channel is emitting audio from two planes (front and left), you can think of it as though it's willing to dedicate 50% of it's total -volume to each of it's planes (a channel position emitting from 1 plane would be willing to given 100% of it's total volume to that plane, and a channel -position emitting from 3 planes would be willing to given 33% of it's total volume to each plane). Similarly, the front/center speaker is emitting audio -from only one plane so you can think of it as though it's willing to _take_ 100% of it's volume from front plane emissions. Now, since the front/left -channel is willing to _give_ 50% of it's total volume to the front plane, and the front/center speaker is willing to _take_ 100% of it's total volume -from the front, you can imagine that 50% of the front/left speaker will be given to the front/center speaker. - -Usage ------ -To use the channel router you need to specify three things: - 1) The input channel count and channel map - 2) The output channel count and channel map - 3) The mixing mode to use in the case where a 1:1 mapping is unavailable - -Note that input and output data is always deinterleaved 32-bit floating point. - -Initialize the channel router with ma_channel_router_init(). You will need to pass in a config object which specifies the input and output configuration, -mixing mode and a callback for sending data to the router. This callback will be called when input data needs to be sent to the router for processing. Note -that the mixing mode is only used when a 1:1 mapping is unavailable. This includes the custom weights mode. - -Read data from the channel router with ma_channel_router_read_deinterleaved().

If you need to change the config you will need to initialize a new device. + +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. + +After initializing the device it will be in a stopped state. To start it, use `ma_device_start()`. + +When sending or receiving data to/from a device, miniaudio will internally perform a format conversion to convert between the format specified by pConfig 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 default using a standard configuration. If you are just needing to do simple playback from the default +playback device this is usually all you need. + +```c +ma_device_config config = ma_device_config_init(ma_device_type_playback); +config.playback.format = ma_format_f32; +config.playback.channels = 2; +config.sampleRate = 48000; +config.dataCallback = ma_data_callback; +config.pMyUserData = pMyUserData; + +ma_device device; +ma_result result = ma_device_init(NULL, &config, &device); +if (result != MA_SUCCESS) { + // Error +} +``` + + +Example 2 - Advanced Initialization +----------------------------------- +This example show how you might do some more advanced initialization. In this hypothetical example we want to control the latency by setting the buffer size +and period count.

Currently, miniaudio's implementation supports rectangular and Hann window -methods. - -Whenever an output sample is being computed, it looks at a sub-section of the input samples. I've called this sub-section in the code below the "window", -which I realize is a bit ambigous with the mathematical "window", but it works for me when I need to conceptualize things in my head. The window is made up -of two halves. The first half contains past input samples (initialized to zero), and the second half contains future input samples. As time moves forward -and input samples are consumed, the window moves forward. The larger the window, the better the quality at the expense of slower processing. The window is -limited the range [MA_SRC_SINC_MIN_WINDOW_WIDTH, MA_SRC_SINC_MAX_WINDOW_WIDTH] and defaults to MA_SRC_SINC_DEFAULT_WINDOW_WIDTH. - -Input samples are cached for efficiency (to prevent frequently requesting tiny numbers of samples from the client). When the window gets to the end of the -cache, it's moved back to the start, and more samples are read from the client. If the client has no more data to give, the cache is filled with zeros and -the last of the input samples will be consumed. Once the last of the input samples have been consumed, no more samples will be output. - - -When reading output samples, we always first read whatever is already in the input cache. Only when the cache has been fully consumed do we read more data -from the client. - -To access samples in the input buffer you do so relative to the window. When the window itself is at position 0, the first item in the buffer is accessed -with "windowPos + windowWidth". Generally, to access any sample relative to the window you do "windowPos + windowWidth + sampleIndexRelativeToWindow". - -**************************************************************************************************************************************************************/ - -/* Comment this to disable interpolation of table lookups.

Note that this can actually change which is explained later. - - Pre Format Conversion -> Sample Rate Conversion -> Channel Routing -> Post Format Conversion - - Pre Format Conversion - --------------------- - This is where the sample data is converted to a format that's usable by the later stages in the pipeline. Input data - is converted to deinterleaved floating-point. - - Channel Routing - --------------- - Channel routing is where stereo is converted to 5.1, mono is converted to stereo, etc. This stage depends on the - pre format conversion stage. - - Sample Rate Conversion - ---------------------- - Sample rate conversion depends on the pre format conversion stage and as the name implies performs sample rate conversion. - - Post Format Conversion - ---------------------- - This stage is where our deinterleaved floating-point data from the previous stages are converted to the requested output - format. - - - Optimizations - ------------- - Sometimes the conversion pipeline is rearranged for efficiency. The first obvious optimization is to eliminate unnecessary - stages in the pipeline. When no channel routing nor sample rate conversion is necessary, the entire pipeline is optimized - down to just this: - - Post Format Conversion - - When sample rate conversion is not unnecessary: - - Pre Format Conversion -> Channel Routing -> Post Format Conversion - - When channel routing is unnecessary: - - Pre Format Conversion -> Sample Rate Conversion -> Post Format Conversion - - A slightly less obvious optimization is used depending on whether or not we are increasing or decreasing the number of - channels. Because everything in the pipeline works on a per-channel basis, the efficiency of the pipeline is directly - proportionate to the number of channels that need to be processed. Therefore, it's can be more efficient to move the - channel conversion stage to an earlier or later stage. When the channel count is being reduced, we move the channel - conversion stage to the start of the pipeline so that later stages can work on a smaller number of channels at a time. - Otherwise, we move the channel conversion stage to the end of the pipeline. When reducing the channel count, the pipeline - will look like this: - - Pre Format Conversion -> Channel Routing -> Sample Rate Conversion -> Post Format Conversion - - Notice how the Channel Routing and Sample Rate Conversion stages are swapped so that the SRC stage has less data to process. - */ - - /* First we need to determine what's required and what's not. */ - if (pConfig->sampleRateIn != pConfig->sampleRateOut || pConfig->allowDynamicSampleRate) { - pDSP->isSRCRequired = MA_TRUE; - } - if (pConfig->channelsIn != pConfig->channelsOut || !ma_channel_map_equal(pConfig->channelsIn, pConfig->channelMapIn, pConfig->channelMapOut)) { - pDSP->isChannelRoutingRequired = MA_TRUE; - } - - /* If neither a sample rate conversion nor channel conversion is necessary we can skip the pre format conversion. */ - if (!pDSP->isSRCRequired && !pDSP->isChannelRoutingRequired) { - /* We don't need a pre format conversion stage, but we may still need a post format conversion stage. */ - if (pConfig->formatIn != pConfig->formatOut) { - pDSP->isPostFormatConversionRequired = MA_TRUE; - } - } else { - pDSP->isPreFormatConversionRequired = MA_TRUE; - pDSP->isPostFormatConversionRequired = MA_TRUE; - } - - /* Use a passthrough if none of the stages are being used. */ - if (!pDSP->isPreFormatConversionRequired && !pDSP->isPostFormatConversionRequired && !pDSP->isChannelRoutingRequired && !pDSP->isSRCRequired) { - pDSP->isPassthrough = MA_TRUE; - } - - /* Move the channel conversion stage to the start of the pipeline if we are reducing the channel count. */ - if (pConfig->channelsOut < pConfig->channelsIn) { - pDSP->isChannelRoutingAtStart = MA_TRUE; - } - - - /* - We always initialize every stage of the pipeline regardless of whether or not the stage is used because it simplifies - a few things when it comes to dynamically changing properties post-initialization. - */ - result = MA_SUCCESS; - - /* Pre format conversion. */ - { - ma_format_converter_config preFormatConverterConfig = ma_format_converter_config_init( - pConfig->formatIn, - ma_format_f32, - pConfig->channelsIn, - ma_pcm_converter__pre_format_converter_on_read, - pDSP - ); - preFormatConverterConfig.ditherMode = pConfig->ditherMode; - preFormatConverterConfig.noSSE2 = pConfig->noSSE2; - preFormatConverterConfig.noAVX2 = pConfig->noAVX2; - preFormatConverterConfig.noAVX512 = pConfig->noAVX512; - preFormatConverterConfig.noNEON = pConfig->noNEON; - - result = ma_format_converter_init(&preFormatConverterConfig, &pDSP->formatConverterIn); - if (result != MA_SUCCESS) { - return result; - } - } - - /* - Post format conversion.

Before I go into +detail about the major changes I would like to apologize. I know it's annoying dealing with breaking API changes, but I think +it's best to get these changes out of the way now while the library is still relatively young and unknown. -Device ------- -- If a full-duplex device is requested and the backend does not support full duplex devices, have ma_device_init__[backend]() - return MA_DEVICE_TYPE_NOT_SUPPORTED. -- If exclusive mode is requested, but the backend does not support it, return MA_SHARE_MODE_NOT_SUPPORTED.

I apologize in +advance for this. You may want to hold off on upgrading for the short term if you're worried. If mini_al v0.8.14 works for +you, and you don't need full-duplex support, you can avoid upgrading (though you won't be getting future bug fixes). + + +Rebranding to "miniaudio" +------------------------- +The decision was made to rename mini_al to miniaudio. Don't worry, it's the same project. The reason for this is simple: + +1) Having the word "audio" in the title makes it immediately clear that the library is related to audio; and +2) I don't like the look of the underscore. + +This rebrand has necessitated a change in namespace from "mal" to "ma". I know this is annoying, and I apologize, but it's +better to get this out of the road now rather than later. Also, since there are necessary API changes for full-duplex support +I think it's better to just get the namespace change over and done with at the same time as the full-duplex changes. I'm hoping +this will be the last of the major API changes. Fingers crossed! + +The implementation define is now "#define MINIAUDIO_IMPLEMENTATION". You can also use "#define MA_IMPLEMENTATION" if that's +your preference. + + +Full-Duplex Support +------------------- +The major feature added to version 0.9 is full-duplex. This has necessitated a few API changes. + +1) The data callback has now changed. Previously there was one type of callback for playback and another for capture. I wanted + to avoid a third callback just for full-duplex so the decision was made to break this API and unify the callbacks. Now, + there is just one callback which is the same for all three modes (playback, capture, duplex). The new callback looks like + the following: + + void data_callback(ma_device* pDevice, void* pOutput, const void* pInput, ma_uint32 frameCount); + + This callback allows you to move data straight out of the input buffer and into the output buffer in full-duplex mode. In + playback-only mode, pInput will be null. Likewise, pOutput will be null in capture-only mode. The sample count is no longer + returned from the callback since it's not necessary for miniaudio anymore. + +2) The device config needed to change in order to support full-duplex. Full-duplex requires the ability to allow the client + to choose a different PCM format for the playback and capture sides. The old ma_device_config object simply did not allow + this and needed to change. With these changes you now specify the device ID, format, channels, channel map and share mode + on a per-playback and per-capture basis (see example below). The sample rate must be the same for playback and capture. + + Since the device config API has changed I have also decided to take the opportunity to simplify device initialization. Now, + the device ID, device type and callback user data are set in the config. ma_device_init() is now simplified down to taking + just the context, device config and a pointer to the device object being initialized. The rationale for this change is that + it just makes more sense to me that these are set as part of the config like everything else. + + Example device initialization: + + ma_device_config config = ma_device_config_init(ma_device_type_duplex); // Or ma_device_type_playback or ma_device_type_capture. + config.playback.pDeviceID = &myPlaybackDeviceID; // Or NULL for the default playback device. + config.playback.format = ma_format_f32; + config.playback.channels = 2; + config.capture.pDeviceID = &myCaptureDeviceID; // Or NULL for the default capture device. + config.capture.format = ma_format_s16; + config.capture.channels = 1; + config.sampleRate = 44100; + config.dataCallback = data_callback; + config.pUserData = &myUserData; + + result = ma_device_init(&myContext, &config, &device); + if (result != MA_SUCCESS) { + ... handle error ... + } + + Note that the "onDataCallback" member of ma_device_config has been renamed to "dataCallback". Also, "onStopCallback" has + been renamed to "stopCallback". + +This is the first pass for full-duplex and there is a known bug. You will hear crackling on the following backends when sample +rate conversion is required for the playback device: + - Core Audio + - JACK + - AAudio + - OpenSL + - WebAudio + +In addition to the above, not all platforms have been absolutely thoroughly tested simply because I lack the hardware for such +thorough testing. If you experience a bug, an issue report on GitHub or an email would be greatly appreciated (and a sample +program that reproduces the issue if possible). + + +Other API Changes +----------------- +In addition to the above, the following API changes have been made: + +- The log callback is no longer passed to ma_context_config_init(). Instead you need to set it manually after initialization. +- The onLogCallback member of ma_context_config has been renamed to "logCallback". +- The log callback now takes a logLevel parameter. The new callback looks like: void log_callback(ma_context* pContext, ma_device* pDevice, ma_uint32 logLevel, const char* message) + - You can use ma_log_level_to_string() to convert the logLevel to human readable text if you want to log it. +- Some APIs have been renamed: + - mal_decoder_read() -> ma_decoder_read_pcm_frames() + - mal_decoder_seek_to_frame() -> ma_decoder_seek_to_pcm_frame() + - mal_sine_wave_read() -> ma_sine_wave_read_f32() + - mal_sine_wave_read_ex() -> ma_sine_wave_read_f32_ex() +- Some APIs have been removed: + - mal_device_get_buffer_size_in_bytes() + - mal_device_set_recv_callback() + - mal_device_set_send_callback() + - mal_src_set_input_sample_rate() + - mal_src_set_output_sample_rate() +- Error codes have been rearranged. If you're a binding maintainer you will need to update. +- The ma_backend enums have been rearranged to priority order. The rationale for this is to simplify automatic backend selection + and to make it easier to see the priority. If you're a binding maintainer you will need to update. +- ma_dsp has been renamed to ma_pcm_converter. The rationale for this change is that I'm expecting "ma_dsp" to conflict with + some future planned high-level APIs. +- For functions that take a pointer/count combo, such as ma_decoder_read_pcm_frames(), the parameter order has changed so that + the pointer comes before the count. The rationale for this is to keep it consistent with things like memcpy(). + + +Miscellaneous Changes +--------------------- +The following miscellaneous changes have also been made. + +- The AAudio backend has been added for Android 8 and above. This is Android's new "High-Performance Audio" API. (For the + record, this is one of the nicest audio APIs out there, just behind the BSD audio APIs). +- The WebAudio backend has been added. This is based on ScriptProcessorNode. This removes the need for SDL. +- The SDL and OpenAL backends have been removed. These were originally implemented to add support for platforms for which miniaudio + was not explicitly supported. These are no longer needed and have therefore been removed. +- Device initialization now fails if the requested share mode is not supported. If you ask for exclusive mode, you either get an + exclusive mode device, or an error. The rationale for this change is to give the client more control over how to handle cases + when the desired shared mode is unavailable. +- A lock-free ring buffer API has been added. There are two varients of this. "ma_rb" operates on bytes, whereas "ma_pcm_rb" + operates on PCM frames. +- The library is now licensed as a choice of Public Domain (Unlicense) _or_ MIT-0 (No Attribution) which is the same as MIT, but + removes the attribution requirement. The rationale for this is to support countries that don't recognize public domain. */ /* REVISION HISTORY ================ +v0.xx.xx - 2020-xx-xx + - Fix potential crash when ma_device object's are not aligned to MA_SIMD_ALIGNMENT. + +v0.9.10 - 2020-01-15 + - Fix compilation errors due to #if/#endif mismatches. + - WASAPI: Fix a bug where automatic stream routing is being performed for devices that are initialized with an explicit device ID. + - iOS: Fix a crash on device uninitialization. + +v0.9.9 - 2020-01-09 + - Fix compilation errors with MinGW. + - Fix compilation errors when compiling on Apple platforms. + - WASAPI: Add support for disabling hardware offloading. + - WASAPI: Add support for disabling automatic stream routing. + - Core Audio: Fix bugs in the case where the internal device uses deinterleaved buffers. + - Core Audio: Add support for controlling the session category (AVAudioSessionCategory) and options (AVAudioSessionCategoryOptions). + - JACK: Fix bug where incorrect ports are connected. + +v0.9.8 - 2019-10-07 + - WASAPI: Fix a potential deadlock when starting a full-duplex device. + - WASAPI: Enable automatic resampling by default.
