Abstract

Sound represents a largely untapped source of realism in Virtual Environments (VEs). In the real world, sound constantly surrounds us and pulls us into our world. In VEs, sound enhances the immersiveness of the simulation and provides valuable information about the environment. While there has been a growing interest in integrating sound into VE interfaces, current technology has not brought about its widespread use. This, we believe, can be attributed to the lack of proper tools for modeling and rendering the auditory world. We have been investigating some of the problems which we believe are pivotal to the widespread use of sound in VE interfaces. As a result of this work, we have developed the Virtual Audio Server (VAS). VAS is a distributed, real-time spatial sound generation server. It provides high level abstractions for modeling the auditory world and the events which occur in the world. VAS supports both sampled and synthetic sound sources and provides a device independent interface to spatialization hardware. Resource management schemes can easily be integrated into the server to manage the real-time generation of sound. We are currently investigating possible approaches to this important problem.
