object RMS extends Serializable

A UGen that calculates the root-mean-square of a first order low-pass filtered input signal. The formula is 'rms = sqrt(lpf1(x^2))'.

Examples
// measure mouse-controlled sine
play {
  // with MouseX at maximum, you'll see that the sine has -3 dB RMS
  val sig = SinOsc.ar(300) * MouseX.kr(0, 1) * LFPulse.ar(0.5)
  val rms = RMS.ar(sig, 10).ampdb.roundTo(0.1).poll(8, "RMS (dB)")
  sig
}

This is a third-party UGen (DEINDUGens).
