DIVA Virtual Audio Reality System
Jyri Huopaniemi, Lauri Savioja, Tapio Takala · 1996
A real-time virtual audio reality model has been created. The system includes model-based sound synthesizers, geometric room acoustics modeling, binaural auralization for headphone or loudspeaker listening, and high-quality animation. The design goals of the overall project have been to create a virtual musical event that is as authentic as possible 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, room acoustics, multimedia and training simulators. There are often computational constraints that lead to simplified systems that faintly resemble the physical reality. We present a distributed expandable virtual audio reality system that can...
