      extended by com.jsyn.unitgen.PeakFollower

public class PeakFollower
extends UnitGenerator

Tracks the peaks of an input signal. This can be used to monitor the overall amplitude of a signal. The output can be used to drive color organs, vocoders, VUmeters, etc. Output drops exponentially when the input drops below the current output level. The output approaches zero based on the value on the halfLife port.
