object StandardN extends ProductReader[StandardN] with Serializable
A non-interpolating sound generator based on the difference equations:
x[n+1] = (x[n] + y[n+1]) % 2pi y[n+1] = (y[n] + k * sin(x[n])) % 2pi
The standard map is an area preserving map of a cylinder discovered by the plasma physicist Boris Chirikov.
Examples
// vary frequency play { StandardN.ar(MouseX.kr(20, SampleRate.ir)) * 0.3 }
// mouse-controlled parameter play { StandardN.ar(SampleRate.ir/2, MouseX.kr(0.9, 4)) * 0.3 }
// as a frequency control play { SinOsc.ar(StandardN.ar(40, MouseX.kr(0.9, 4)) * 800 + 900) * 0.4 }
