This coded is duplicated in at least six nodes now. It would be better to have an AudioNode constructor or method that takes an AudioNodeOptions.

Won't the bindings generator always pass a default-initialized dictionary?

Yes I agree with you. The default values (when not specified in the dictionary) differ from node to node though so we have to watch out for that.
I will try and find a good way to factor this is a follow-up patch. Maybe it can wait until we're done adding all constructor to avoid conflicting.

Yes, but this is also called from BaseAudioContext::createGain() above.
