.wav files can be included into your programs to produce sound. The first things you will want to do is to include the .wav file to your Make.sh so it gets added when building, and also include it into your .xml file. Then in your Program you will want to include the audtio.h library and define the sound.

  #include "audio.h"
  #define your_sound number

To use sound in your program you will want to reference the audio.h library using the C API reference http://www.vircon32.com/api.html

a simple function example

  play_sound( your_sound );
