YantraGo

Watch sound become shape. YantraGo simulates the Chladni patterns that form when a vibrating plate is driven at a frequency. It solves the wave equation, so the pattern you see is one a real plate would make.

Real physics

A finite-difference solver for the 2D wave equation, checked against the exact solutions for square and circular plates.

Tune by ear and eye

Scrub a spectrum of the plate's resonances, snap to peaks, and see each mode settle in seconds.

Your plate, your rules

Square or circular, clamped or free, membrane or thin plate, any number of drivers and four waveforms.

Export

Save PNG images and animated GIFs of frequency sweeps. Everything you make is yours to use.
