final case class PV_HainsworthFoote(rate: Rate, chain: GE, hainsworth: GE = 0.0f, foote: GE = 0.0f, thresh: GE = 1.0f, waitTime: GE = 0.04f) extends SingleOut with IsIndividual with Product with Serializable

An FFT based onset detector UGen using a balance of two features. It is based on work described in Hainsworth (2003), "Techniques for the Automated Analysis of Musical Audio," PhD thesis, University of Cambridge. See especially p. 128. The Hainsworth metric is a modification of the Kullback Liebler distance.

chain

the fft signal (buffer) to analyze

hainsworth

what strength of detection signal from Hainsworth metric (0 to 1) to use.

foote

what strength of detection signal from normalized Foote metric (0 to 1) to use.

thresh

threshold level for detection

waitTime

after an onset is detected, further detections are suppressed for this period in seconds, preventing multiple rapid triggers
