*
*   raylib [audio] example - Using audio module as standalone module
*
*   NOTE: This example does not require any graphic device, it can run directly on console.
*
*   [audio] module requires some external libs:
*       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
*
*   Compile audio module using:
*   gcc -c audio.c stb_vorbis.c -Wall -std=c99 -DAUDIO_STANDALONE
*
*   Compile example using:
*   gcc -o $(NAME_PART).exe $(FILE_NAME) audio.o stb_vorbis.o -lopenal32 -std=c99
*
*   This example has been created using raylib 1.5 (www.raylib.com)
