A physical modeling synthesis resonator.
A New Kind of Physical Modeling
Physical modeling synthesis consists of two parts: an exciter and a resonator. Whistles exciter uses granulated audio samples which is then fed into the banded waveguide resonator: a series of delay lines and tuned bandpass filters. The result is a loose modeling of a bowed elastic solid — similar to marimbas or vibraphones.
The Exciter
The “bow” of the instrument is an audio sample of your choice. With powerful spraying and window shaping parameters, the exciter can be full of bumps or smooth to the touch.
Resonator
The “body” of the instrument adds organic resonance through a series of delay lines and tuned bandpass filters. Each bandpass filter can be tuned to a harmonic ratio or to a fixed frequency, modeling materials of and out of this world.
Narrow or widen the bandpass filters to dial in the “stiffness” of the resonator. Whistle additionally has a unique shift and target parameters for easily tuning inharmonic timbre.
Modulation
A simple modulation section can animate any of Whistles parameters. A simple function generator can be toggled between an envelope or an LFO.
Pull apart the exciter source or bend and tear the resonator with just a few clicks.
