AudioNode class abstract

The AudioNode is a generic for representing an audio processing module.

Examples include:

• an audio source (e.g. an HTML audio or video element, an OscillatorNode, etc.),
• the audio destination,
• intermediate processing module (e.g. a filter like BiquadFilterNode or ConvolverNode), or
• volume control (like GainNode)

Note: An AudioNode can be target of events, therefore it implements the EventTarget interface.

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 pair

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 pair

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 pair

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 setter

hashCode → int

The hash code for this object.

no setter, inherited

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 setter

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 setter

runtimeType → Type

A representation of the runtime type of the object.

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

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.

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

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.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toString() → String

A string representation of this object.

Operators

operator ==(Object other) → bool

The equality operator.
