Lag2UD exponential lag

Inherits from: Object : AbstractFunction : UGen : Filter : Lag

Lag2UD.ar(in, lagTimeU, lagTimeD, mul, add))

Lag2UD.kr(in, lagTimeU, lagTimeD, mul, add))

Lag2 is equivalent to Lag.kr(Lag.kr(in, time), time), thus resulting in a smoother transition. This saves on CPU as you only have to calculate the decay factor once instead of twice. See Lag for more details.

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.
