Secure context: This feature is available only in secure contexts (HTTPS), in some or all supporting browsers.

The AudioWorklet interface of the Web Audio API is used to supply custom audio processing scripts that execute in a separate thread to provide very low latency audio processing.

The worklet's code is run in the AudioWorkletGlobalScope global execution context, using a separate Web Audio thread which is shared by the worklet and other audio nodes.

Access the audio context's instance of AudioWorklet through the BaseAudioContext.audioWorklet property.
