class:: Limiter

|
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));
|
