| Abstract | We present an interactive algorithm and system (RESound) for sound propagation and rendering in virtual environments and media applications. RESound uses geometric propaga-tion techniques for fast computation of propagation paths from a source to a listener and takes into account specu-lar reflections, diffuse reflections, and edge diffraction. In order to perform fast path computation, we use a unified ray-based representation to efficiently trace discrete rays as well as volumetric ray-frusta. RESound further improves sound quality by using statistical reverberation estimation techniques. We also present an interactive audio rendering algorithm to generate spatialized audio signals. The over-all approach can handle dynamic scenes with no restrictions on source, listener, or obstacle motion. Moreover, our algo-rithm is relatively easy to parallelize on multi-core systems. We demonstrate its performance on complex game-like and architectural environments. |
