Could these overrides be private? I can’t think of any reason someone would call these on an AudioNode directly rather than through an EventTarget&, so making them private would be nice.

These read better on single lines, to my taste. And I see no reason to name it “evt” instead of event”.

Yes, these can be moved into private:.

Sure thing.  Thanks!

I take that back.  They're called by the wrapper (JSAudioNode) directly, so they need to be public.
