class:: Lag3UD
summary:: Exponential lag
categories:: UGens>Filters
related:: Classes/Lag, Classes/Lag2, Classes/Lag3, Classes/LagUD, Classes/Lag2UD
description::
Lag3UD is equivalent to LagUD.kr(LagUD.kr(LagUD.kr(in, timeU, timeD), timeU, timeD), timeU, timeD), thus resulting in a smoother transition. This saves on CPU as you only have to calculate the decay factor once instead of three times. See link::Classes/LagUD:: for more details.
classmethods::
method:: ar, kr
argument:: in
input signal.
argument:: lagTimeU
60 dB lag time in seconds for the upgoing signal.
argument:: lagTimeD
60 dB lag time in seconds for the downgoing signal.
examples::
code::
(
// used to lag pitch
SynthDef( \lag3ud_help,
{ arg freq=300,lagup=1, lagdown=5;
Out.ar( 0,
SinOsc.ar( // sine wave
Lag3UD.kr( // lag the frequency
freq,
lagup,
lagdown
),
0, // phase
0.2 // sine amplitude
)
);
}).send(s);
)
x = Synth.new( \lag3ud_help ); // create the synth
x.set( \freq, 500 ); // set the frequency to a higher value (takes 1 second)
x.set( \freq, 100 ); // set the frequency to a lower value (takes 5 seconds)
x.free;
