Looks like there's a WebAssembly version of Audacity 2.x named 'Wavacity'. You can check it out here: https://wavacity.com/
The dev behind it, ahilss on Github, appears to have forked wxWidgets and PortAudio to add WebASM support.
In that case, we have a fun project idea: porting these changes to newer versions of wxWidgets, PortAudio, and Tenacity.
@falktx Yep. We're not fans of analytics either...
...but this version appears to be an older 2.x version, without any networking. But then again, we don't know the exact modifications to this version...
