extends EventTarget

An AudioContext can be a target of events, therefore it implements the EventTarget interface.

Constructor

new (audioChannelType:AudioChannel)

new ()

Throws:

null

DOMError

Variables

read onlycurrentTime:Float

Returns a double representing an ever-increasing hardware time in seconds used for scheduling. It starts at 0.

read onlydestination:AudioDestinationNode

Returns an AudioDestinationNode representing the final destination of all audio in the context. It can be thought of as the audio-rendering device.

read onlylistener:AudioListener

Returns the AudioListener object, used for 3D spatialization.

onstatechange:Function

An event handler that runs when an event of type statechange has fired. This occurs when the AudioContext's state changes, due to the calling of one of the state change methods (AudioContext.suspend, AudioContext.resume, or AudioContext.close).

read onlysampleRate:Float

Returns a float representing the sample rate (in samples per second) used by all nodes in this context. The sample-rate of an AudioContext cannot be changed.

read onlystate:AudioContextState

Returns the current state of the AudioContext.
