Some background: between 1996 and 2000 I studied
for my PhD in the Signal
Processing Group of the Cambridge
University Engineering Department. My thesis was entitled: Signal
Separation of Musical Instruments; Simulation-based methods for musical
signal decomposition and transcription. In short, this was
concerned with the analysis of polyphonic audio signals using
sophisticated probabilistic techniques, Markov-chain Monte Carlo
(MCMC).
