BaseAudioContext class
The interface of the Web Audio API acts as a base definition for online and offline audio-processing graphs, as represented by AudioContext and OfflineAudioContext respectively. You wouldn't use directly — you'd use its features via one of these two inheriting interfaces. A can be a target of events, therefore it implements the EventTarget interface.
