object ZeroCrossing extends Serializable

A pitch estimation UGen based on counting the zero-crossings of the input signal. This is a very crude pitch follower, but can be useful in some situations.

Examples
// reconstruct sine frequency
play {
  val f1 = SinOsc.kr(0.2).madd(600, 700).roundTo(100)
  val a  = SinOsc.ar(f1) * 0.1
  val f2 = ZeroCrossing.ar(a)
  f2.poll(10, "estimation")
  val b  = SinOsc.ar(f2) * 0.1
  Seq(a, b)
}
