Category: Multimedia
Type: New or changed feature
Status: Enabled by default (Chrome 66)

Summary

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.
