**Lag ****exponential lag**

**Lag.ar(in, lagTime, mul, add)**

**Lag.kr(in, lagTime, mul, add)**

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.

**in** - input signal

**lagTime** - 60 dB lag time in seconds.
