* - Format wave data (sample rate, size, channels)
* - Play/Stop/Pause/Resume loaded audio
* - Manage mixing channels
* - Manage raw audio context
*
* 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)
