Eigendrum

Draw any shape and hear what it would sound like as a drum — real physics, in the browser.

Webfreeglobal

Eigendrum lets you draw any outline and hear it as a drum: it solves the real vibration eigenvalue problem for your shape with finite elements, so striking different spots excites different modes — audibly. Individual modes can be played alone, and the solver is validated against exactly known cases. A playful, rigorous way into wave physics.
