ChannelMergerNode class abstract
The ChannelMergerNode
interface, often used in conjunction with its
opposite, ChannelSplitterNode, reunites different mono inputs into a
single output. Each input is used to fill a channel of the output. This is
useful for accessing each channels separately, e.g. for performing channel
mixing where gain must be separately controlled on each channel.
If ChannelMergerNode
has one single output, but as many inputs as there
are channels to merge; the number of inputs is defined as a parameter of its
constructor and the call to BaseAudioContext.createChannelMerger. In the
case that no value is given, it will default to 6
.
Using a ChannelMergerNode
, it is possible to create outputs with more
channels than the rendering hardware is able to process. In that case, when
the signal is sent to the BaseAudioContext.listener object, supernumerary
channels will be ignored.
Number of inputs | variable; default to 6 . |

Number of outputs | 1 |
Channel count mode | "explicit" |
Channel count | 2 (not used in the default count mode) |
Channel interpretation | "speakers" |

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 anumberOfInputs
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.

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 anotherAudioNode
(thereby directing the sound data to the specified node). See also AudioNode.connectParaminherited -
connectParam(
AudioParam destinationParam, [int output, int input]) → void -
This is a variant of AudioNode.connect with a
DestinationParam
argument instead of anAudioNode
. 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.disconnectParaminherited -
disconnectParam(
AudioParam destinationParam, [int output, int input]) → void -
This is a variant of AudioNode.disconnect with a
DestinationParam
argument instead of anAudioNode
. 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.

Operators
-
operator ==(
Object other) → bool -
The equality operator.
