I just wanted to visualize a waveform, randomly searched for "audacity like online", not expecting much... and by god, they did it. The maniacs.

Wavacity | Online Audio Editor Based on Audacity

Wavacity is a port of the Audacity audio editor to the web browser. Free and open-source. No install required.

@zeh I wonder if they used webasm for that. I don't have enough experience with that to tell. It is pretty cool.

@jacket I think that's what it is, from what I've heard.

Wasm is never simple, but if the whole stack is already wasm-friendly and not super OS-API-dependent, it's doable. Audacity seems to sit in that sweet spot.
