3-D sound reproduction and virtual reality systems

Abstract

Computer simulation of acoustic scenes is an important prerequisite of rendering. Technology for 3-D sound reproduction, the so-called “audio front end” or the “acoustic human-machine interface” is an essential component of VR systems, which must be capable of fulfilling high quality standards involving psychoacoustically relevant cues. These cues may differ from one VR application to the next. Some applications require an exact localization, while for others, monaural spectral features such as reproduction with exact loudness and timbre are more important.
