Web Audio API: "The interfaces defined are:
An AudioContext interface, which contains an audio signal graph representing connections betweens AudioNodes.
An AudioNode interface, which represents audio sources, audio outputs, and intermediate processing modules. AudioNodes can be dynamically connected together in a modular fashion. AudioNodes exist in the context of an AudioContext
An AudioSourceNode interface, an abstract AudioNode subclass representing a node which generates audio.
An AudioDestinationNode interface, an AudioNode subclass representing the final destination for all rendered audio.
An AudioBuffer interface, for working with memory-resident audio assets. These can represent one-shot sounds, or longer audio clips.
An AudioBufferSourceNode interface, an AudioNode which generates audio from an AudioBuffer.
A MediaElementAudioSourceNode interface, an AudioNode which is the audio source from an audio, video, or other media element.
A JavaScriptAudioNode interface, an AudioNode for generating or processing audio directly in JavaScript.
An AudioProcessingEvent interface, which is an event type used with JavaScriptAudioNode objects."
