The average˜ object computes a running average of an input signal over a specified number of samples. It can provide three different average types, “bipolar”, “absolute”, and “rms”.
The avg˜ object computes the average of the absolute value of an input signal between bangs.
The meter˜ object provides a graphical signal level meter.
The snapshot˜ object outputs the current audio sample value when a bang is received.
The peakamp˜ object reports the maximum absolute value of audio data between bangs or at regular intervals.
The spike˜ object reports intervals of zero to non-zero transitions.
The zerox˜ object counts zero-crossings, which can be used to distinguish transients from pitched signals.
