Convention Paper

Audio Signal Decorrelation Based on a Critical Band Approach

Authors: Boueri, Maurice; Kyriakakis, Chris

AES Convention 117 · Paper 6291 · October 2004

Abstract

This paper presents a new method for decorrelating audio signals by applying a random time shift to each critical band. The resulting signals exhibit a significantly lower inter-aural cross-correlation. The effects of this type of decorrelation on perceived envelopment and loss of phantom image will be presented.
