Audio doesn’t seem to work in mobile safari.

Why does the submitted link redirect? Is that allowed on HN

very nice! but having the "this space for rent" , space is the thing that realy says that it's someone doing there thing, everything is cool, no worrys, here play with a drum, and you knid of know that whoever might go in that space will be truely random, and interesting to some further subset of those that jump at an internet drum thing. thanks!

should be a vst intrument

Hi HN, I built Eigendrum, a web tool that solves the 2D wave equation for arbitrary shapes so you can hear what they sound like as drums.

How it works: * Solves -∇²u = λu using finite element analysis (Kφ = λMφ) on a triangle mesh. * Validated to <0.1% error against closed-form solutions for circles (Bessel zeros) and rectangles. * Sound model factors in strike location, Rayleigh damping, and mallet width. * Includes Kac drums I & II to demonstrate identical sound spectra from different geometries. * No frameworks, build steps, or dependencies.

Repo and tests: https://github.com/BaselAshraf81/eigendrum

Happy to answer any questions about the FEM solver or Web Audio setup!
