/**********************************************************************************************
*
*   raudio v1.0 - A simple and easy-to-use audio library based on miniaudio
*
*   FEATURES:
*       - Manage audio device (init/close)
*       - Manage raw audio context
*       - Manage mixing channels
*       - Load and unload audio files
*       - Format wave data (sample rate, size, channels)
*       - Play/Stop/Pause/Resume loaded audio
*
*   CONFIGURATION:
*
*   #define RAUDIO_STANDALONE
*       Define to use the module as standalone library (independently of raylib).
*       Required types and functions are defined in the same module.
*
*   #define SUPPORT_FILEFORMAT_WAV
*   #define SUPPORT_FILEFORMAT_OGG
*   #define SUPPORT_FILEFORMAT_XM
*   #define SUPPORT_FILEFORMAT_MOD
*   #define SUPPORT_FILEFORMAT_FLAC
*   #define SUPPORT_FILEFORMAT_MP3
*       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
*
*   DEPENDENCIES:
*       miniaudio.h  - Audio device management lib (https://github.com/dr-soft/miniaudio)
*       stb_vorbis.h - Ogg audio files loading (http://www.nothings.org/stb_vorbis/)
*       dr_mp3.h     - MP3 audio file loading (https://github.com/mackron/dr_libs)
*       dr_flac.h    - FLAC audio file loading (https://github.com/mackron/dr_libs)
*       jar_xm.h     - XM module file loading
*       jar_mod.h    - MOD audio file loading
*
*   CONTRIBUTORS:
*       David Reid (github: @mackron) (Nov. 2017):
*           - Complete port to miniaudio library
*
*       Joshua Reisenauer (github: @kd7tck) (2015)
*           - XM audio module support (jar_xm)
*           - MOD audio module support (jar_mod)
*           - Mixing channels support
*           - Raw audio context support
