The program listed below demonstrates double buffering with the audio
device.  Run the program from the CLI.  It takes one parameter - the name
of an IFF 8SVX sample file to play on the Amiga's audio device. The
maximum size for a sample on the Amiga is 128K. However, by using
double-buffering and queueing up requests to the audio device, you can
play longer samples smoothly and without breaks.
