class:: Limiter
summary:: Peak limiter
related:: Classes/Amplitude, Classes/Compander, Classes/CompanderD, Classes/Normalizer
categories:: UGens>Dynamics
Description::
Limits the input amplitude to the given level. Limiter will not overshoot
like link::Classes/Compander:: will, but it needs to look ahead in the
audio. Thus there is a delay equal to twice the value of the
code::dur:: parameter.
Limiter, unlike Compander, is completely transparent for an in range signal.
classmethods::
method::ar
argument::in
The signal to be processed.
argument::level
The peak output amplitude level to which to normalize the input.
argument::dur
aka lookAheadTime.
The buffer delay time. Shorter times will produce smaller delays
and quicker transient response times, but may introduce amplitude
modulation artifacts.
Examples::
code::
(
// example signal to process
Synth.play({
var z;
z = Decay2.ar(
Impulse.ar(8, LFSaw.kr(0.25, -0.6, 0.7)),
0.001, 0.3, FSinOsc.ar(500));
}, 0.8)
)
(
Synth.play({
var z;
z = Decay2.ar(
Impulse.ar(8, LFSaw.kr(0.25, -0.6, 0.7)),
0.001, 0.3, FSinOsc.ar(500));
[z, Limiter.ar(z, 0.4, 0.01)]
}, 0.5)
)
