class:: PV_MagFreeze
summary:: Freeze magnitudes.
categories:: UGens>FFT
Description::
Freezes magnitudes at current levels when code::freeze:: > 0.
classmethods::
method::new
argument::buffer
FFT buffer.
argument::freeze
If > 0, then magnitudes are frozen at current levels.
Examples::
code::
s.boot;
b = Buffer.read(s, Platform.resourceDir +/+ "sounds/a11wlk01.wav");
(
SynthDef("help-magFreeze", { arg out=0;
var in, chain;
in = SinOsc.ar(LFNoise1.kr(5.2,250,400));
chain = FFT(LocalBuf(2048), in);
// moves in and out of freeze
chain = PV_MagFreeze(chain, SinOsc.kr(0.2) );
Out.ar(out, 0.1 * IFFT(chain).dup);
}).play(s);
)
(
//trig with MouseY
SynthDef("help-magFreeze2", { arg out=0, soundBufnum=2;
var in, chain;
in = PlayBuf.ar(1, soundBufnum, BufRateScale.kr(soundBufnum), loop: 1);
chain = FFT(LocalBuf(2048), in);
chain = PV_MagFreeze(chain, MouseY.kr > 0.5 );
Out.ar(out, 0.1 * IFFT(chain).dup);
}).play(s,[\soundBufnum, b]);
)
