# Lag

Exponential lag
Source: /Applications/SuperCollider/SuperCollider.app/Contents/Resources/SCClassLibrary/Common/Audio/Filter.sc
Inherits from: Filter : UGen : AbstractFunction : Object
Subclasses: Lag2, Lag3, Ramp

## Description

This is essentially the same as 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 VarLag.

## Class Methods

### *kr (in = 0, lagTime = 0.1, mul = 1, add = 0)

#### Arguments:

 in The input signal. lagTime 60 dB lag time in seconds. mul Output will be multiplied by this value. add This value will be added to the output.

## Examples

(
// 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
)
