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.
Sound
Stiffness, damping, mallet width, where the strike lands: every variable bends the tone. Nudge them until the metal sings, then sculpt it with the filter and delay. Sonic beauty, tweaked to taste.
Hear it
Three waveforms. Plate, sine, saw.
Strike the physical plate for inharmonic, gong-like tones, or switch to the sine and saw engines and play it as a synth, with every control remapped to fit. Each preset below is one engine in a different mood. Audio files will be added shortly — click a card to see the wiring.
Want to try it on your own material? Download and install the plugin — it runs as a fully functional free trial, with a short noise wash over the output every 30 seconds until you activate it with a license key.
