Real-Time Acoustics Simulation using Mesh-Tracing

A number of techniques have been presented recently to simulate or predict the acoustics of a room. Among these we can find reverberation algorithms based on waveguide meshes and acoustic ray-tracing. Both approaches have disadvantages, such as an excessive amount of computation required (resulting in only off-line simulations) or aliasing phenomena caused by non-uniform speed of sound distribution of the travelling waves. This paper presents a novel approach to simulating acoustics in real-time which solves the problems mentioned or significantly improves the quality of existing mesh-based reverberation algorithms.
