object RunningSum extends ProductReader[RunningSum] with Serializable

A UGen calculating the sum of an input signal over a sliding window of given number of samples.

Note: Unlike RunningMin and RunningMax , this is not a trigger based operation, but at any one time, the sum of the past length values is reported, continuously sliding the analysis window.

Examples
// poll waveform's DC offset
play {
  val freq = 441
  val n    = SampleRate.ir / freq
  // mean over period of a pulse with 50% duty is 0.5
  val mean = RunningSum.ar(LFPulse.ar(freq), n) / n
  mean.roundTo(0.01).poll(label = "mean")
  ()
}
