# WorldViz Copyright 2002====================================================
# This script demonstrates the use of 3D sound, otherwise known as spatialized
# sound.  To mimic the sound changes that occur in real environments with
# real sounds, the computer will change the sound being played between the
# two speakers (or 4 speakers for fancy cards) to create the sense of spatialized
# sound.  Vizard uses Microsoft Direct Sound as it's interface to this procedure,
# which in turn will use any 3D sound acceleration that is available on your
# sound card.  As such, you'll have to turn to either Microsoft or your sound
# card manufacturer to try and figure out what is really going on.  Good luck.
#
# In this demo, the sounds are played from the bell tower, fountain, and avatar.
