MediaStreamTrackAudioSourceNode class abstract

The MediaStreamTrackAudioSourceNode is a type of AudioNode which represents a source of audio data taken from a specific MediaStreamTrack obtained through the WebRTC or Media Capture and Streams APIs.

The audio itself might be input from a microphone or other audio sampling device, or might be received through a RTCPeerConnection, among other possible options.

A MediaStreamTrackAudioSourceNode has no inputs and exactly one output, and is created using the AudioContext.createMediaStreamTrackSource method. This is similar to MediaStreamAudioSourceNode, except it lets you specifically state the track to use, rather than assuming the first audio track on a stream.

Number of inputs 0
Number of outputs 1
Channel count defined by the first audio [MediaStreamTrack] passed to the [AudioContext.createMediaStreamTrackSource] method that created it.

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
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.
