Description::
Multiplies magnitudes of two inputs and keeps the phases of the first input.
classmethods::
method::new
argument::bufferA
FFT buffer A.
argument::bufferB
FFT buffer B.
Examples::
code::
s.boot;
b = Buffer.read(s, Platform.resourceDir +/+ "sounds/a11wlk01.wav");

inB = LFSaw.ar(100, 0, 0.2);
chainA = FFT(LocalBuf(2048), inA);
chainB = FFT(LocalBuf(2048), inB);
chain = PV_MagMul(chainA, chainB);
Out.ar(out, 0.1 * IFFT(chain).dup);
