* raylib.audio - Basic funtionality to work with audio
*
* This module provides basic functionality to work with audio:
* Manage audio device (init/close)
* Load and Unload audio files (WAV, OGG, FLAC, XM, MOD)
* Play/Stop/Pause/Resume loaded audio
* Manage mixing channels
* Manage raw audio context
*
* NOTES:
*
* Only up to two channels supported: MONO and STEREO (for additional channels, use AL_EXT_MCFORMATS)
* Only the following sample sizes supported: 8bit PCM, 16bit PCM, 32-bit float PCM (using AL_EXT_FLOAT32)
* FEATURES:
* - Manage audio device (init/close)
* - Load and unload audio files
* - Format wave data (sample rate, size, channels)
* - Play/Stop/Pause/Resume loaded audio
* - Manage mixing channels
* - Manage raw audio context
*
* CONFIGURATION:
*
* #define AUDIO_STANDALONE
* If defined, the module can be used as standalone library (independently of raylib).
* Define to use the module as standalone library (independently of raylib).
* Required types and functions are defined in the same module.

* Selected desired fileformats to be supported for loading. Some of those formats are
* supported by default, to remove support, just comment unrequired #define in this module
*
* #define SUPPORT_RAW_AUDIO_BUFFERS
* LIMITATIONS:
* Only up to two channels supported: MONO and STEREO (for additional channels, use AL_EXT_MCFORMATS)
* Only the following sample sizes supported: 8bit PCM, 16bit PCM, 32-bit float PCM (using AL_EXT_FLOAT32)
