Research

Cover of the Wang/Brown book on computational auditory scene analysis
My main research interest is Computational Auditory Scene Analysis (CASA), which aims to build machine systems that mimic the ability of human listeners to segregate complex mixtures of sound. I also have interests in reverberation-robust automatic speech recognition, auditory-motivated techniques for sonar signal processing and music technology.

The following recent book gives an overview of the field:

DeLiang Wang and Guy J. Brown (editors), Computational auditory scene analysis: Principles, Algorithms, and Applications. IEEE Press/Wiley-Interscience, 2006

You can get more information from amazon.co.uk or amazon.com, or go to the web site that accompanies the book.

I am also a member of an interdisciplinary music information systems research group, MISTRES
