AudioNode extension type
The AudioNode
interface is a generic interface for representing an
audio processing module.
Examples include:
- an audio source (e.g. an HTML
audio
orvideo
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 interface 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 interface 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 interface 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 setterinherited
- numberOfInputs → int
-
The
numberOfInputs
property of the AudioNode interface returns the number of inputs feeding the node. Source nodes are defined as nodes having anumberOfInputs
property with a value of 0.no setter - numberOfOutputs → int
-
The
numberOfOutputs
property of the AudioNode interface 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
-
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 anotherAudioNode
(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. -
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. -
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 withdispatchEvent()
.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.
