-/**********************************************************************************************
-*
-* raudio - 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
