MediaElementAudioSourceNode extension type

The MediaElementAudioSourceNode interface represents an audio source consisting of an HTML audio or video element. It is an AudioNode that acts as an audio source.

A MediaElementAudioSourceNode has no inputs and exactly one output, and is created using the AudioContext.createMediaElementSource method. The number of channels in the output equals the number of channels of the audio referenced by the HTMLMediaElement used in the creation of the node, or is 1 if the HTMLMediaElement has no audio.

Number of inputs	0
Number of outputs	1
Channel count	2 (but note that [AudioNode.channelCount] is only used for up-mixing and down-mixing [AudioNode] inputs, and [MediaElementAudioSourceNode] doesn't have any input)

Methods

addEventListener(String type, EventListener? callback, [JSAny options]) → void

The addEventListener() method of the EventTarget interface sets up a function that will be called whenever the specified event is delivered to the target.

inherited

connect(JSObject destinationNodeOrDestinationParam, [int output, int input]) → AudioNode?

The connect() method of the AudioNode interface lets you connect one of the node's outputs to a target, which may be either another AudioNode (thereby directing the sound data to the specified node) or an AudioParam, so that the node's output data is automatically used to change the value of that parameter over time.

inherited

disconnect([JSAny destinationNodeOrDestinationParamOrOutput, int output, int input]) → void

The disconnect() method of the AudioNode interface lets you disconnect one or more nodes from the node on which the method is called.

inherited

dispatchEvent(Event event) → bool

The dispatchEvent() method of the EventTarget sends an Event to the object, (synchronously) invoking the affected event listeners in the appropriate order. The normal event processing rules (including the capturing and optional bubbling phase) also apply to events dispatched manually with dispatchEvent().

inherited

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

removeEventListener(String type, EventListener? callback, [JSAny options]) → void

The removeEventListener() method of the EventTarget interface removes an event listener previously registered with EventTarget.addEventListener from the target. The event listener to be removed is identified using a combination of the event type, the event listener function itself, and various optional options that may affect the matching process; see Matching event listeners for removal.

inherited

toString() → String

A string representation of this object.

Operators

operator ==(Object other) → bool

The equality operator.
