class:: PV_MagDiv
summary:: Division of magnitudes
categories:: UGens>FFT
description::
Divides magnitudes of two inputs and keeps the phases of the first input.
classmethods::
private:: categories
method:: new
argument:: bufferA
fft buffer A.
argument:: bufferB
fft buffer B.
argument:: zeroed
number to use when bins are zeroed out, i.e. causing division by zero (defaults to 0.0001)
examples::
code::
s.boot;
(
SynthDef("help-magMul", { arg out=0;
var inA, chainA, inB, chainB, chain;
inA = WhiteNoise.ar(0.2);
inB = LFSaw.ar(100, 0, 0.2);
chainA = FFT(LocalBuf(2048), inA);
chainB = FFT(LocalBuf(2048), inB);
chain = PV_MagDiv(chainA, chainB);
Out.ar(out, 0.5 * IFFT(chain).dup);
}).play;
)
c = Buffer.read(s, Platform.resourceDir +/+ "sounds/a11wlk01.wav");
(

var inA, chainA, inB, chainB, chain;
