PV_BinWipe combine low and high bins from two inputs

Inherits from: Object : AbstractFunction : UGen : PV_ChainUGen

PV_BinWipe(bufferA, bufferB, wipe)

Copies low bins from one input and the high bins of the other.

bufferA - fft buffer A.

bufferB - fft buffer B.

wipe - can range between -1 and +1.

if wipe == 0 then the output is the same as inA.

if wipe > 0 then it begins replacing with bins from inB from the bottom up.

if wipe < 0 then it begins replacing with bins from inB from the top down.
