@section{description}


Randomly clear bins.


@section{classmethods}
 

@section{method}
 new

@section{argument}
 buffer

FFT buffer.


@section{argument}
 wipe

Clears bins from input in a random order as wipe goes from 0 to
1.


@section{argument}
 trig

A trigger, that selects a new random ordering.
