Distinguished Scientist

Applied Technologies

Audio and acoustic engineering

My expertise is in audio engineering, acoustics and signal processing. These have been applied to a number of commercial products. I have also produced a significant publication record.

I am the inventor of the technology underlying the Meyer Constellation system for the electroacoustic enhancement of room acoustics. More recently, I have been working in microphone array processing and have collaborated with the New Zealand company Dotterel Technologies to develop an innovative shotgun microphone that is now winning international awards. 

I’m also working on virtual reality sound recording solutions using novel microphone arrays.
