I have now retired. My active research interests were in auditory perception and in speech perception - more specifically in auditory grouping and the "cocktail-party" effect. Listen to a recent BBC Radio 4 program that I contributed to on the cocktail-party problem (12 Mbyte mp3 file).

Praat
Paul Boersma's excellent, free, multi-platform, user-friendly, stable, well-maintained, scriptable program for doing a multitude of tasks in speech and hearing research is here. Tell your friends about it. Some Praat scripts that I have written for doing changes to speech vocal tract size, Fo and duration and for producing sine-wave speech and Shannon AM-noise speech are here.

Sheet Chamber Music Exchange
I played violin in the National Youth Orchestra from 1961-63, and led the University of Sussex Orchestra in the 1980s when it was conducted by Michael Hall.
I will usually drop everything (including hints) to play chamber music.
Here is the start of a sight-read Haydn string-quartet Op20 movement, recorded with a dummy head in our living room. Haydn.mp3(900kBytes). NB Dummy-head recordings should be listened to over stereo-headphones, not over loudspeakers; they give a good impression of out-thereness - and a little bit of help with poor intonation!
Sonata for Violin & Piano by Christopher Longuet-Higgins
This sonata was initially written by Christopher Longuet-Higgins while he was a young man at Oxford, but was revised and converted to computer readable format after he retired. I have corrected some errors in the Encore score and added some phrase marks, metronome marks and dynamics with the composer's assistance.
Please download the piano and violin parts and play it. Please email any errors or downloading, unzipping, formatting problems to me. The extracted parts are in pdf format.
