class:: LeakDC
summary:: Remove DC
related:: Classes/DC
categories:: UGens>Filters>Linear
Description::
This is a linear filter that removes DC bias from a signal. Specifically, this is a one-pole highpass filter implementing the formula code:: y[n] = x[n] - x[n-1] + coef * y[n-1] ::. The frequency response of this filter is dependent on the sample rate of the server and the calculation rate of the UGen.
classmethods::
method::ar, kr
argument::in
The input signal.
argument::coef
Leak coefficient.
argument::mul
Output will be multiplied by this value.
argument::add
This value will be added to the output.
Examples::
code::
(
{
var a;
a = LFPulse.ar(800, 0.5, 0.5, 0.5);
[a, LeakDC.ar(a, 0.995)]
}.scope(bufsize: 22050)
)
