Extraction of a source from multichannel data using sparse decomposition
It was discovered recently that sparse decomposition by signal dictionaries results in dramatic improvement of the qualities of blind source separation. We exploit sparse decompos...

Harmonic Distortion Measurement using Spectral Warping
Harmonic distortion may be characterised by the proportion of energy of a sinusoidal signal transferred to the harmonics. Differential time scaling resulting from the spectral war...

A Distributed Approach to Musical Composition
Current techniques for automated composition use a single algorithm, focusing on one aspect of musical generation. In our system we make use of several algorithms, distributed usin...
