MediaElementAudioSourceNode class abstract

The MediaElementAudioSourceNode 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)

Properties

channelCount ↔ int
The channelCount property of the AudioNode represents an integer used to determine how many channels are used when up-mixing and down-mixing connections to any inputs to the node.
getter/setter pairinherited
channelCountMode ↔ ChannelCountMode
The channelCountMode property of the AudioNode represents an enumerated value describing the way channels must be matched between the node's inputs and outputs.
getter/setter pairinherited
channelInterpretation ↔ ChannelInterpretation
The channelInterpretation property of the AudioNode interface represents an enumerated value describing how input channels are mapped to output channels when the number of inputs/outputs is different. For example, this setting defines how a mono input will be up-mixed to a stereo or 5.1 channel output, or how a quad channel input will be down-mixed to a stereo or mono output.
getter/setter pairinherited
context → BaseAudioContext
The read-only context property of the AudioNode returns the associated BaseAudioContext, that is the object representing the processing graph the node is participating in.
no setterinherited
hashCode → int
The hash code for this object.
no setterinherited
mediaElement → MediaElement
The MediaElementAudioSourceNode interface's read-only mediaElement property indicates the HTMLMediaElement that contains the audio track from which the node is receiving audio.
no setter
numberOfInputs → int
The numberOfInputs property of the AudioNode returns the number of inputs feeding the node. Source nodes are defined as nodes having a numberOfInputs property with a value of 0.
no setterinherited
numberOfOutputs → int
The numberOfOutputs property of the AudioNode returns the number of outputs coming out of the node. Destination nodes — like AudioDestinationNode — have a value of 0 for this attribute.
no setterinherited
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited

Methods

connect(AudioNode destinationNode, [int output, int input]) → AudioNode
The connect() method of the AudioNode 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). See also AudioNode.connectParam
inherited
connectParam(AudioParam destinationParam, [int output, int input]) → void
This is a variant of AudioNode.connect with a DestinationParam argument instead of an AudioNode. Note : The W3C recommandation uses just one verb for both.
inherited
disconnect([AudioNode destinationParamOrOutput, int output, int input]) → void
The disconnect() method of the AudioNode lets you disconnect one or more nodes from the node on which the method is called. See also AudioNode.disconnectParam
inherited
disconnectParam(AudioParam destinationParam, [int output, int input]) → void
This is a variant of AudioNode.disconnect with a DestinationParam argument instead of an AudioNode. Note : The W3C recommandation uses just one verb for both.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
toString() → String
A string representation of this object.
