Abstract

Artificial reverberation continues to be a source of much research and development. Currently, there is a heavy emphasis on 'auralization,' or the ability to simulate physical structures' sound characteristics using computer modeling. The diffuse component of early-order reflections has been acknowledged as an important component of reverb for several decades and has been implemented since the 1970s in varying forms. The current paper details a method of simulating diffuse reflections by use of fading models commonly used in wireless communications. The method is then considered as a stereo field enhancement effect and as a component of a reverberation system. Both are implemented in MATLAB and the results are discussed.
