Additional auditory stimulation appears to have much potential, as it realizes a multisensory system. This is especially useful when the user does not have to wear any additional hardware, e.g., headphones. Creating a virtual sound scene with spatially distributed sources requires a technique for adding spatial cues to audio signals and an appropriate reproduction. In this paper we present a real-time audio rendering system that combines dynamic crosstalk cancellation and multi-track binaural synthesis for virtualacoustical imaging. This provides the possibility of simulating spatially distributed sources and, in addition to that, near-to-head sources for a freely moving listener in room-mounted virtual environments without using any headphones. A special focus will be put on near-to-head acoustics, and requirements in respect of the head-related transfer function databases are discussed. %L 004 %K Crosstalk cancellation %K Spatial Acoustics %K binaural synthesis %K interactive Virtual Reality %K multi-modality %R 10.20385/1860-2037/3.2006.2 %U http://nbn-resolving.de/urn:nbn:de:0009-6-5890 %U http://dx.doi.org/10.20385/1860-2037/3.2006.2
