|
Description::
|
|
|
|
Clears bins above or below a cutoff point.
|
|
|
|
|
|
classmethods::
|
|
|
|
method::new
|
|
|
|
argument::buffer
|
|
|
|
FFT buffer.
|
|
|
|
|
|
argument::wipe
|
|
|
|
Can range between -1 and +1.
|
|
|
|
|
|
If
|
|
code::wipe:: == 0 then there is no effect.
|
|
|
|
|
|
If
|
|
code::wipe:: > 0 then it acts like a high
|
|
pass filter, clearing bins from the bottom up.
|
|
|
|
|
|
If
|
|
code::wipe:: < 0 then it acts like a low
|
|
pass filter, clearing bins from the top down.
|
|
|
|
|
|
Examples::
|
|
|
|
code::
|
|
|
|
s.boot;
|
|
|
|
(
|
|
{
|
|
var in, chain;
|
|
in = WhiteNoise.ar(0.2);
|
|
chain = FFT(LocalBuf(2048), in);
|
|
chain = PV_BrickWall(chain, SinOsc.kr(0.1));
|
|
IFFT(chain);
