Resonator

Object

object

Options: Pipe · Plate · Tank · Chain · I-Beam · Taut Cable · Coil Spring · Sheet Metal · Industrial Cog
Default: Pipe

Pipe: Longitudinal pipe response with dedicated length, diameter, and sustain controls.
Plate: 2D plate response balancing overall span, aspect ratio, and material stiffness.
Tank: Shell-and-cavity behavior with volume, wall thickness, cavity balance, and shell decay.
Chain: Linked resonator behavior shaped by link weight, chain length, instability, and friction loss.
I-Beam: Beam-like modes with explicit mass, shear density, and rigidity damping emphasis.
Taut Cable: Stiff string response with tension, braid stiffness, and dynamic pitch-drop control.
Coil Spring: Dispersive spring response controlled by coil length, chirp density, and slosh instability.
Sheet Metal: Thin-sheet response with size, thinness, and edge damping rather than generic brightness knobs.
Industrial Cog: Circular blade behavior with radius, tooth dissonance, and blade thickness control.
