AudioWorklet (which allows you to work with audio sample-by-sample in a dedicated, high priority "thread") is available and works well in Firefox and the latest Safari. I haven't tried it in Edge, but I believe it's also working well.

Oh yeah, you're right, they've been added since I last looked into it. Nice!

Safari on iOS is still missing some important features that severely limits its usage.

This is true for many web features, including many basic PWA features like web push notifications, url capture, etc...

As a mobile first web developer, ios is the thing that's really holding us back.

The very frustrating thing about this is that the end user tends to blame the app, and there's not a good way to communicate to them "hey, we would totally do this, but mobile Safari has limited functionality and Apple won't allow other browsers to be installed"
