object Squiz extends Serializable

A UGen implementing a simplistic pitch-raising algorithm. It is not meant to sound natural, and its sound is reminiscent of some weird mixture of filter, ring-modulator and pitch-shifter, depending on the input.

The algorithm works by cutting the signal into fragments (delimited by upwards-going zero-crossings) and squeezing those fragments in the time domain (i.e. simply playing them back faster than they came in), leaving silences in between.

Examples
// trigger grains
play { Squiz.ar(SinOsc.ar(440), MouseX.kr(1, 10, 1), zeroCrossings = MouseY.kr(1, 10)) * 0.1 }

This is a third-party UGen (MCLDUGens).

  4. def ar(in: GE, pitchRatio: GE = 2, zeroCrossings: GE = 1, maxDur: GE = 0.1f): Squiz

    in

    input signal to be distorted

    pitchRatio

    the ratio by which pitch will be raised, e.g. the default value of 2 will raise by one octave. Only upwards pitch-shifts are possible so a value below 1 has no effect.

    zeroCrossings

    how many positive-going zero-crossings are used to delimit a chunk.

    maxDur

    the maximum duration to remember each fragment, corresponding with an internally allocated memory. Raising it higher will use more real-time memory and probably will not sound very different (especially if zeroCrossings is low). (init-time only)
