PV_PartialSynthF | SuperCollider 3.12.2 Help

Description

PV_NoiseSynthF and PV_PartialSynthF base these decisions on whether or not freq data across numFrames is within a given threshold

PV_PartialSynthF(buffer, threshold, numFrames)

Class Methods

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

From superclass: PV_NoiseSynthP

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 frequecy
    // will be returned. Upper limit should be Nyqust / nBins , e.g. 22050 / 2048 -> 21.532
    // or + and - 21.532
    chain = PV_NoiseSynthF(chain, MouseX.kr(0, 21.532));
    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);
