class:: OneZero
summary:: One zero filter.
related:: Classes/OnePole
categories:: UGens>Filters>Linear
Description::
A one zero filter. Implements the formula:
code::
out(i) = ((1 - abs(coef)) * in(i)) + (coef * in(i-1)).
::
classmethods::
method::ar, kr
argument::in
The input signal.
argument::coef
Feed forward coefficient.
+0.5 makes a two point averaging filter
(see also
link::Classes/LPZ1:: ).
-0.5 makes a differentiator
(see also
link::Classes/HPZ1:: ).
+1 makes a single sample delay
(see also
link::Classes/Delay1:: ).
-1 makes an inverted single sample delay.
argument::mul
Output will be multiplied by this value.
argument::add
This value will be added to the output.
Examples::
code::
{ OneZero.ar(WhiteNoise.ar(0.5), 0.5) }.play
{ OneZero.ar(WhiteNoise.ar(0.5), -0.5) }.play
{ OneZero.ar(WhiteNoise.ar(0.5), Line.kr(-0.5, 0.5, 10)) }.play
