class:: Lag
summary:: Exponential lag
related:: Classes/Lag2, Classes/Lag3, Classes/VarLag, Classes/LagUD
categories:: UGens>Filters>Linear
Description::
This is essentially the same as link::Classes/OnePole:: except that
instead of supplying the coefficient directly, it is calculated from a 60
dB lag time. This is the time required for the filter to converge to
within 0.01% of a value. This is useful for smoothing out control
signals.
For linear and other alternatives, see link::Classes/VarLag::.
classmethods::
method::ar, kr
argument::in
The input signal.
argument::lagTime
60 dB lag time in seconds.
argument::mul
Output will be multiplied by this value.
argument::add
This value will be added to the output.
Examples::
code::
(
// used to lag pitch
{
SinOsc.ar( // sine wave
Lag.kr( // lag the modulator
LFPulse.kr(4, 0, 0.5, 50, 400), // frequency modulator
Line.kr(0, 1, 15) // modulate lag time
),
0, // phase
0.3 // sine amplitude
)
}.play
)
