Cusp map chaotic generator
Source: Chaos.sc
Subclasses: CuspL

Description

A non-interpolating sound generator based on the difference equation:

    x(n+1) = a - b * sqrt(|x(n)|)

sclang code translation:

(
var a = 1.0, b = 1.9, xi = 0, size = 64;
plot(size.collect { xi = a - (b * sqrt(abs(xi))) });
)

Examples

// vary frequency
{ CuspN.ar(MouseX.kr(20, SampleRate.ir), 1.0, 1.99) * 0.3 }.play(s);

// mouse-controlled params
{ CuspN.ar(SampleRate.ir/4, MouseX.kr(0.9,1.1,1), MouseY.kr(1.8,2,1)) * 0.3 }.play(s);

// as a frequency control
{ SinOsc.ar(CuspN.ar(40, MouseX.kr(0.9,1.1,1), MouseY.kr(1.8,2,1))*800+900)*0.4 }.play(s);
