Paper abstract
In this paper we propose a novel approach to sound reverberation based on the the geometric analysis of the acoustic environment, which allows the listener to freely move within it. The method is based on a combination of a tapped delay line for early reverberation, designed through beam tracing; and a wave digital network for late reverberation, designed through path tracing. The method is efficient enough to enable a real-time sound rendering for Virtal Reality applications, on low-cost PC platforms.
