A real-time virtual audio reality model has been created. The system includes model-based sound synthesizers, geometrical room acoustics modeling, binaural auralization for headphone or loudspeaker listening, and hiqh-quality animation. This paper discusses the following subsystems of the designed environment: The implementation of the audio processing soft- and hardware, and the design of a dedicated multiprocessor DSP hardware platform. The design goal of the overall project has been to create a virtual musical event that is authentic both in terms of audio and visual quality. Novelties of this system include a real-time image-source algorithm for rooms of arbitrary shape, shorter HRTF filter approximations for more efficient auralization, and a network-based distributed implementation of the audio processing soft- and hardware. 1 Introduction Application fields of virtual audio reality environments include computer music, acoustics, and multimedia. There are often computational con...
