Lag3UD

Exponential lag
Inherits from: LagUD : Filter : PureUGen : UGen : AbstractFunction : Object

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 LagUD for more details.

Class Methods

*ar (in: 0, lagTimeU: 0.1, lagTimeD: 0.1, mul: 1, add: 0)

From superclass: LagUD

*kr (in: 0, lagTimeU: 0.1, lagTimeD: 0.1, mul: 1, add: 0)

From superclass: LagUD

Arguments:

in

input signal.

lagTimeU

60 dB lag time in seconds for the upgoing signal.

lagTimeD

60 dB lag time in seconds for the downgoing signal.

Examples

(
// 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

            )
        );
    }).add;
)

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;
