The AudioWorklet allows developers to supply JavaScript to process audio on the audio rendering thread. This processing mechanism ensures the synchronous execution of the author code with other built-in AudioNodes in the audio graph. The AudioWorklet is designed to replace ScriptProcessorNode. ScriptProcessorNode will be deprecated once AudioWorklet is shipped.
