dc.description.abstractThe human auditory system, in contrast to the human visual system, can perceive input from all directions and has no limited field of view. As such, it provides valuable cues for navigation and orientation in virtual environments. However, audio stimuli are not that common in today s Virtual Reality applications, and this might result from the lack of middleware or user acceptance due to the need for specialized or costly hardware. Surprisingly, the lack of headphone-less near body acoustics is widely accepted, and simple intensity panning approaches that enable plausible spatial audio are used. This paper describes a networked environment for sophisticated binaural synthesis-based audio rendering in visual VR applications for a freely moving listener in a CAVE-like environment without the use of headphones. It describes the binaural acoustics rendering technique and a dynamic crosstalk cancellation system for four loudspeakers. In addition to that, synchronization issues and network coupling together with performance measurements that proof the applicability of the system in interactive Virtual Environments are discussed.en_US
