class:: PV_BrickWall
summary:: Zero bins.
related:: Classes/FFT, Classes/IFFT
categories:: UGens>FFT
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;
b = Buffer.alloc(s,2048,1);
(
SynthDef("help-brick", { arg out=0, bufnum=0;
var in, chain;
in = {WhiteNoise.ar(0.2)}.dup;
chain = FFT(bufnum, in);
chain = PV_BrickWall(chain, SinOsc.kr(0.1));
Out.ar(out, IFFT(chain).dup);
}).play(s,[\out, 0, \bufnum, b.bufnum]);
)
