@section{description}


Break a continuous signal into linearly interpolated segments with specific durations.

Feeding Ramp with noise is similar to link::Classes/LFNoise1::

@racketblock[
Ramp.kr(WhiteNoise.kr(1),0.5)
::
is equal to:
]

@racketblock[
LFNoise1.kr(1 / 0.5)
::

For smoothing out control signals, take a look at link::Classes/Lag:: and link::Classes/VarLag::

@section{method}
 ar, kr

@section{argument}
 in

The input signal.


@section{argument}
 lagTime

segment duration in seconds.


@section{argument}
 mul

Output will be multiplied by this value.


@section{argument}
 add

This value will be added to the output.
