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