AudioWorkletNode class

Note: Although the interface is available outside secure contexts, the BaseAudioContext.audioWorklet property is not, thus custom AudioWorkletProcessors cannot be defined outside them.

The interface of the Web Audio API represents a base class for a user-defined AudioNode, which can be connected to an audio routing graph along with other nodes. It has an associated AudioWorkletProcessor, which does the actual audio processing in a Web Audio rendering thread.
