The product
A real plate, not a metaphor.
CymaticPlate simulates a clamped Kirchhoff plate with explicit finite-difference time-domain integration. Audio excites the plate. The plate rings. Sand finds the nodal lines. You hear physics, not a synth pretending to be one.
Plate physics
13-point biharmonic stencil, validated against published clamped plate eigenvalues. Not a modal synth.
Cymatic visualiser
Live sand particles drift to the nodal lines as the plate rings. The figure forms in front of you.
Mac native
AU and VST3. Real-time safe, no allocation on the audio thread, pluginval clean at strictness 8.
Hear it
Four presets. One plate, four personalities.
Built by varying stiffness, damping, strike position, and mallet width. Audio files will be added shortly — click a card to see the wiring.
