AudioDestinationNode extension type

The AudioDestinationNode interface represents the end destination of an audio graph in a given context — usually the speakers of your device. It can also be the node that will "record" the audio data when used with an OfflineAudioContext.

AudioDestinationNode has no output (as it is the output, no more AudioNode can be linked after it in the audio graph) and one input. The number of channels in the input must be between 0 and the maxChannelCount value or an exception is raised.

The AudioDestinationNode of a given AudioContext can be retrieved using the BaseAudioContext.destination property.

Number of inputs 1
Number of outputs 0
Channel count mode "explicit"
Channel count 2
Channel interpretation "speakers"

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 pairinherited
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 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 interface 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
maxChannelCount → int
The maxchannelCount property of the AudioDestinationNode interface is an unsigned long defining the maximum amount of channels that the physical device can handle.
no setter
numberOfInputs → int
The numberOfInputs property of the AudioNode interface 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 interface 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

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.
