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") () }
