PeakFollower

A UGen that continually reports the peak amplitude of the signal received at the input. If the absolute input level drops below the observed peak value, this value decreases by the factor given as decay parameter (but no more than the current absolute input level).

Examples

// mouse-controlled decay
play {
  val in    = Impulse.ar(2)
  val decay = MouseX.kr(0.995, 1.0001, 1).min(1.0)
  decay.poll(HPZ1.kr(decay).abs, "decay")
  val p     = PeakFollower.ar(in, decay)
  val tr    = Impulse.ar(20)
  val pm    = RunningMax.ar(p, tr)
  pm.roundTo(0.001).poll(20, "peak")
  in
}
