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 is a port of the Audacity audio editor to the web browser. Free and open-source. No install required.
@vl1 :( sorry.
It's really just Audacity in a browser tab.
