PV_HainsworthFoote

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
