Well, the stack trace weirdly looked familiar to me so I did a little bit of search.

By design, ScriptProcessorNode has data race. Also as noted in the linked issue, the feature is deprecated from the spec so now sure if it is worth to fix the issue.

The potential fix would be generating a new AudioBuffer for every render quantum and it will affect many WebAudio projects out there.
