This plugin uses the correlation method described in \cite{krumhansl1990} and \cite{gomez2006}, but using different tone profiles. The key profiles used in this implementation are drawn from analysis of Book I of the Well Tempered Klavier by J S Bach, recorded at A=440 equal temperament, as described in \cite{noland2007signal}. @@ -65,7 +65,7 @@ \section{Audio Onset Detection} -The Note Onset Detector VAMP plugin analyses a single channel of audio and estimates the onset times of notes within the music -- that is, the times at which notes and other audible events begin. +The Note Onset Detector Vamp plugin analyses a single channel of audio and estimates the onset times of notes within the music -- that is, the times at which notes and other audible events begin. It calculates an onset likelihood function for each spectral frame, and picks peaks in a smoothed version of this function.

It returns a numeric value (the segment type) for each moment at which a new segment starts. For music with clearly tonally distinguishable sections such as verse, chorus, etc., segments with the same type may be expected to be similar to one another in some structural sense. For example, repetitions of the chorus are likely to share a segment type.
