* raylib.audio
*
* Basic functions to manage Audio:
* Manage audio device (init/close)
* Load and Unload audio files
* Play/Stop/Pause/Resume loaded audio
* Manage mixing channels
* Manage raw audio context
*
* Uses external lib:
* OpenAL Soft - Audio device management lib (http://kcat.strangesoft.net/openal.html)
* stb_vorbis - Ogg audio files loading (http://www.nothings.org/stb_vorbis/)
* jar_xm - XM module file loading
* jar_mod - MOD audio file loading
*
* Many thanks to Joshua Reisenauer (github: @kd7tck) for the following additions:
* XM audio module support (jar_xm)
* MOD audio module support (jar_mod)
* Mixing channels support
* Raw audio context support
