Towards Automatic Rhythmic Accompaniment

Research interests

My main research interests are in application of signal processing techniques to the automatic extraction of rhythmic information from audio signals. In particular, I have developed methods for estimating tempo and beat locations, time-signature and bar boundaries and predominant rhythmic patterns for rhythmic style classification. Beyond the extraction of rhythmic meta-data, I have begun to explore rhythm based processing of audio signals, including real-time beat-based effects and rhythmic transformations. I am also interested in the issue of evaluation towards finding perceptually appropriate methods for quantitatively measuring the success of rhythmic analysis.

Outside of the domain of rhythmic analysis, I developed a real-time decoder for a low bit rate encoded signals as part of the recent Object Based Coding of Musical Audio Project.

I am currently working on the application of low-level feature extraction to aid in the automatic evaluation of music therapy recordings.
