Abstract

We describe a computationally efficient spatial reverberation and 3-D positional audio mixing architecture for real-time virtual acoustics using headphones or loudspeakers. A new method for binaural synthesis of massive numbers of sound sources is introduced. Extensions of the processing architecture are described for modeling spatially extended sound events, simulating near-field emitters, rendering multi-room reverberation and incorporating the perceptually salient features of early reflections and acoustic obstructions in the listener's immediate virtual environment. The proposed approach enables the implementation of scalable interactive 3D audio rendering systems in personal computers, game consoles, set top boxes or mobile phones. The associated scene representation model is compatible with current interactive audio standards, including OpenAL, MPEG-4 and JSR-234.
