class:: LinCongC
summary:: Linear congruential chaotic generator
categories:: UGens>Generators>Chaotic
related:: Classes/LinCongN, Classes/LinCongL
description::
A cubic-interpolating sound generator based on the difference equation:
code::
x[n+1] = (a * x[n] + c) % m
::
warning:: revise formulae converted to c like code ::
The output signal is automatically scaled to a range of [-1, 1].
classmethods::
method:: ar
argument:: freq
Iteration frequency in Hertz
argument:: a
Multiplier amount
argument:: c
Increment amount
argument:: m
Modulus amount
argument:: xi
Initial value of x
examples::
code::
// default initial params
{ LinCongC.ar(MouseX.kr(20, SampleRate.ir)) * 0.2 }.play(s);
::
code::
// randomly modulate params
(
{ LinCongC.ar(
LFNoise2.kr(1, 1e4, 1e4),
LFNoise2.kr(0.1, 0.5, 1.4),
LFNoise2.kr(0.1, 0.1, 0.1),
LFNoise2.kr(0.1)
) * 0.2 }.play(s);
)
::
code::
// as frequency control...
(
{
SinOsc.ar(
LinCongC.ar(
40,
LFNoise2.kr(0.1, 0.1, 1),
LFNoise2.kr(0.1, 0.1, 0.1),
