This is an example of automatic interpretation of an anapest rhythm undergoing extreme asymmetrical rubato (tempo variation). The foot-tapper plays a hi-hat sound along to a test anapestic rhythm (repeated short-short-long) which is being varied in it’s tempo. The tapper has found the underlying repetition rate and selectively chosen to tap on the first beat…

The continuous wavelet transform (CWT) of Morlet and Grossman can also be applied to decompose a rhythm represented by a continuous trace of event “salience” derived directly from the audio signal. We use a measure of event salience developed by our EmCAP partners Prof. Sue Denham and Dr. Martin Coath at the University of Plymouth.…
