@section{description}


Lag2 is equivalent to 
@racketblock[ 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  link::Classes/Lag::  for more
details.

 ar, kr

@section{argument}
 in

The input signal.

		0.3	// sine amplitude
