This paper describes the implementation of the sound system used to ge
nerate aural cues for use in the distributed virtual environment of NP
SNET. This sound system is called the NPSNET-3D Sound Server. It is a
MIDI-based loudspeaker system consisting of commercial, off-the-shelf
equipment. This sound system currently generates 2-D aural cues via fo
ur speakers, but is designed for the potential generation of 3-D aural
cues via a cube configuration of eight speakers.
