A fast and accurate “shoebox” room acoustics simulator

Abstract

We present a new ldquoshoeboxrdquo room acoustics simulator that is designed to support research into signal processing algorithms that are robust to reverberation. It is an improvement over existing room acoustics simulators because it is computationally fast, portable to many kinds of research environments, and flexible to use. The proposed simulator is also perceptually accurate because it models both specular and diffuse surface reflections. An efficient implementation of the simulator is made freely available for download from the open source project ROOMSIM on SourceForge.
