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;
