PV_NoiseSynthP | SuperCollider 3.12.2 Help

Subclasses: PV_NoiseSynthF, PV_PartialSynthF, PV_PartialSynthP

Description

PV_NoiseSynthP and PV_PartialSynthP base these decisions on whether or not phase data across numFrames is within a given threshold.

Class Methods

PV_NoiseSynthP.new(buffer, threshold: 0.1, numFrames: 2, initflag: 0)

Arguments:

buffer	The FFT buffer.
threshold	A phase value (in radians) with which to allow values to pass through or be zeroed out.
numFrames	The number of FFT frames needed to make the above decision.
initflag	If 0, all bins are zeroed out while the initial is calculated. If 1, all bins pass through.

Examples

s.boot;

{SinOsc.ar(440, 0, 0.5) + PinkNoise.ar(0.4)}.play; // a sample sig

(SynthDef(\partialsynth, {arg fftbuf;
 var in, chain, out;
 in = SinOsc.ar(440, 0, 0.5) + PinkNoise.ar(0.4);
 chain = FFT(fftbuf, in);
  // resynhtesize according to MouseX if 0, only sound with VERY stable changes of phase
  // will be returned. If pi, everything will be returned (+ or - pi)
 chain = PV_PartialSynthP(chain, MouseX.kr(0, pi));
 out = IFFT(chain);
 Out.ar(0, out.dup);
 }).add;
)

// the fft buf
s.sendMsg(\b_alloc, 0, 2048);

// start the synth
s.sendMsg(\s_new, \partialsynth, z = s.nextNodeID, 0, 1, \fftbuf, 0);
// free it
s.sendMsg(\n_free, z);
s.sendMsg(\b_free, 0);

(SynthDef(\noisesynth, {arg fftbuf;
 var in, chain, out;
 in = SinOsc.ar(440, 0, 0.5) + PinkNoise.ar(0.4);
 chain = FFT(fftbuf, in);
  // resynhtesize according to MouseX if 0, every thing will be returned... as the value
  // increases, bins with VERY stable change of phase are zeroed out, until everything is
  // at +-pi
 chain = PV_NoiseSynthP(chain, MouseX.kr(0, pi));
 out = IFFT(chain);
 Out.ar(0, out.dup);
 }).add;
)

// the fft buf
s.sendMsg(\b_alloc, 0, 2048);

// start the synth
s.sendMsg(\s_new, \noisesynth, z = s.nextNodeID, 0, 1, \fftbuf, 0);
// free it
s.sendMsg(\n_free, z);
s.sendMsg(\b_free, 0);
