class:: Slew
summary:: Slew rate limiter.
related:: Classes/Slope, Classes/Ramp, Classes/Lag, Classes/VarLag
categories:: UGens>Filters>Nonlinear
Description::
Limits the slope of an input signal. The slope is expressed in units per
second.
For smoothing out control signals, take a look at link::Classes/Lag:: and link::Classes/VarLag::
classmethods::
method::ar, kr
argument::in
The input signal.
argument::up
Maximum upward slope in units per second.
argument::dn
Maximum downward slope in units per second.
argument::mul
Output will be multiplied by this value.
argument::add
This value will be added to the output.
Examples::
code::
(
{
z = LFPulse.ar(800);
[z, Slew.ar(z, 4000, 4000)]
}.plot)
Has the effect of removing transients and higher frequencies.
(
{
z = Saw.ar(800,mul:0.2);
Slew.ar(z,400,400)
}.play
)
