Detailed Description

Detects if input contains a onset point.

PeakerOnset is based on the onset peak picking algorithm presented in:

Dixon, S. (2006). Onset detection revisited. In Proc. International Conference on Digital Audio Effects (DAFx), Montreal, Canada.

It takes as input an onset function over time (i.e. a row vector with the times series of a onset function like flux) and evaluates a specific point for onset presence, as below:

Input = [zzzzzzzzzXyyy]

Point "X" at the input will be evaluated. The onsetWinSize control specifies a "look ahead" parameter, i.e. how many samples (represented above as "y") after "X" will be used for evaluating if it is an onset or not (i.e. look ahead samples).
