DynKlank : UGen : AbstractFunction : Object

Description

DynKlank is a bank of frequency resonators which can be used to simulate the resonant modes of an object. Each mode is given a ring time, which is the time for the mode to decay by 60 dB.

Unlike Klank, all parameters in DynKlank can be changed in real-time after it has been started.

Class Methods

DynKlank.ar(specificationsArrayRef, input, freqscale: 1.0, freqoffset: 0.0, decayscale: 1.0)

DynKlank.kr(specificationsArrayRef, input, freqscale: 1.0, freqoffset: 0.0, decayscale: 1.0)

Examples

Four resonators each at maximum amplitude of 1.0 and ring times of 1 second, different exciters and no scaling:
