. is algorithm
amplitude modulates a carrier by an exponential to create a more complex
harmonic structure. e simplest carrier is a sinusoid which produces a
spectrum with a Gaussian distribution centered on the carrier. More
complicated waveforms produce Gaussians around each harmonic,
producing spectra similar to comb ltered noise.
Interface
MORPH
- changes the waveform of oscillator A
DAMP
- sets the decay constant on oscillator B relative to its period
MOD
- phase modulates oscillator A by oscillator B
FOLD
- sets the wave fold threshold on the nal wave folder
Pitch A is the fundamental frequency of the carrier. Pitch B is the retrigger
frequency of the exponential decay.
