 Combine low and high bins from two inputs.@section{categories}
  UGens>FFT

@section{description}


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


@section{classmethods}
 

@section{method}
 new

@section{argument}
 bufferA

FFT buffer A.


@section{argument}
 bufferB

FFT buffer B.


@section{argument}
 wipe

Can range between -1 and +1.


If

@racketblock[wipe::  == 0, then the output is the same
as
]

@racketblock[bufferA:: .


If
]

@racketblock[wipe::  > 0, then it begins replacing
with bins from
]

@racketblock[bufferB::  from the bottom up.


If
]

@racketblock[wipe::  < 0, then it begins replacing
with bins from
]

@racketblock[bufferB::  from the top down.
