Biography

Dr Martin Dewhirst joined the University as a Lecturer in August 2009. Martin's teaching focuses on signal processing, sound synthesis and computer audio systems.

 

Prior to being appointed as lecturer, Martin was worked as a Research Assistant on the QESTRAL research project, a collaboration between the University of Surrey's IoSR and CVSSP, Bang & Olufsen and BBC Research and Development. The aim of this project was to develop an objective measure of the spatial quality of spatial audio processing systems. While working on the QESTRAL project, Martin also completed his PhD at the University of Surrey, with a thesis titled Modelling perceived spatial attributes of reproduced sound. His current research interests include the relationship between audio quality and lower level perceptual attributes, subjective testing and modelling the perceived spatial attributes of reproduced sound using objective measurements.
