BASS audio test

BASS-test.cpp

// BASS demo test
// A very basic OpenGL/GLUT application
// Create a window, load some sounds and play them.
// A test program for BASS - available from http://www.un4seen.com/
// This program uses two sound effects - available from http://www.freesound.org/
// To test this program you will need two wav sound effect files!
