DuffingOsc
Extension
ExtensionChaotic driven oscillator based on the Duffing function.
Description
A chaotic oscillating sound generator based on integration of the Duffing function:
d2y/dt2 = amp * cos(omega * t) - (damping * dy/dt) - (stiffness * y) - (nonLinearity * y * y * y)Class Methods
.ar
All inputs to DuffingOsc are sampled at control rate.
Arguments:
| freq |
Frequency of driving oscillator in Hz. |
| amp |
Amplitude of driving oscillator (so amp in the above equation). |
| damping |
Amount of resistance to velocity in the spring. |
| stiffness |
How much force the spring responds to with linear compression. |
| nonLinearity |
The degree of nonlinearity in the spring response. Larger numbers indicate higher nonlinearity, and 0 makes a purely linear spring. |
