Abstract:
Sound is certain to become a standard component of Virtual Environment (VE) interfaces. Current technology, however, has not brought about the wide spread use of sound in VEs. Research efforts have focused primarily on the localization problem - making sounds appear to emanate from a particular direction in 3D space. The problems of modeling the sonic environment and sound generation have not been adequately addressed. This paper presents the Virtual Audio Server (VAS), a system designed to address the problems of integrating sound into VEs. VAS is a real-time, distributed sound server. It provides high level abstractions for modeling the sonic environment. VAS's extensible architecture allows it to support a variety of rendering techniques. Parameterizable synthetic sound source are supported and a novel graceful degradation technique manages the real-time generation of those sound sources.
