Dynamic Cross-Talk Cancellation for Binaural Synthesis in Virtual Reality Environments

To create a Virtual Reality environment with true immersion a precise spatial audio reproduction system is required. Since the placement of large loudspeaker arrays which are needed for wave field synthesis systems may be impossible for some environments, alternative solutions must be found. One application of this kind, for instance, is a multi screen VR system where the stereoscopic video images envelope the user. In such a case the presented binaural approach has many advantages. This paper describes the virtual sound source imaging by binaural synthesis and the reproduction over loudspeakers with a dynamic (tracked) cross-talk cancellation system which only needs three to four loudspeakers to cover all listening positions.
