class:: OnePole
summary:: One pole filter.
related:: Classes/OneZero
categories:: UGens>Filters>Linear
Description::
A one pole filter. Implements the formula:
code::
out(i) = ((1 - abs(coef)) * in(i)) + (coef * out(i-1)).
::
classmethods::
method::ar, kr
argument::in
The input signal.
argument::coef
Feedback coefficient. Should be between -1 and +1
argument::mul
Output will be multiplied by this value.
argument::add
This value will be added to the output.
Examples::
code::
{ OnePole.ar(WhiteNoise.ar(0.5), 0.95) }.play
{ OnePole.ar(WhiteNoise.ar(0.5), -0.95) }.play
{ OnePole.ar(WhiteNoise.ar(0.5), Line.kr(-0.99, 0.99, 10)) }.play
