Safari has stricter use gesture requirements than other browsers. We don't allow starting rendering without a user gesture. I see the demo asks the user to click a button to start rendering but my bet is that it actually starts the rendering asynchronously after getting the click.

Yes, I mean the click handler calls an async function which does a: ``` await e.audioWorklet.addModule(n), ``` Before it connects the node to the graph. By that time, the user gesture is lost in Safari. I wish we could relax the user gesture requirement a bit (e.g. only require a "recent" gesture) but I usually get push back from our media team when I suggest that.
