@section{description}


Crossfades between two sounds by copying bins in a random order.


@section{classmethods}
 

@section{method}
 new

@section{argument}
 bufferA

FFT buffer A.


@section{argument}
 bufferB

FFT buffer B.


@section{argument}
 wipe

Copies bins from bufferB in a random order as wipe goes from 0
to 1.


@section{argument}
 trig

A trigger, that selects a new random ordering.


@section{Examples}

s.boot;

//trig with MouseY

	chainB = FFT(LocalBuf(2048), inB);
