class:: Integrator
summary:: A leaky integrator.
categories::  UGens>Filters>Linear, UGens>Maths


Description::

Integrates an input signal with a leak. The formula implemented is:

code::
out(0) = in(0) + (coef * out(-1))
::


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::

{ Integrator.ar(LFPulse.ar(300, 0.2, 0.1), MouseX.kr(0.001, 0.999, 1)) }.play

// used as an envelope
{ Integrator.ar(LFPulse.ar(3, 0.2, 0.0004), 0.999, FSinOsc.ar(700), 0) }.play


// scope

{ Integrator.ar(LFPulse.ar(1500 / 4, 0.2, 0.1), MouseX.kr(0.01, 0.999, 1)) }.scope
