ChannelSplitterNode extension type
The ChannelSplitterNode
interface, often used in conjunction with its
opposite, ChannelMergerNode, separates the different channels of an audio
source into a set of mono outputs. This is useful for accessing each channel
separately, e.g. for performing channel mixing where gain must be separately
controlled on each channel.
If your ChannelSplitterNode
always has one single input, the amount of
outputs is defined by a parameter on its constructor and the call to
BaseAudioContext/createChannelSplitter
. In the case that no value is
given, it will default to 6
. If there are fewer channels in the input than
there are outputs, supernumerary outputs are silent.
Number of inputs | 1 |
---|---|
Number of outputs | variable; default to 6 . |
Channel count mode |
"explicit" Older implementations, as per earlier versions
of the spec use "max" .
|
Channel count |
Fixed to the number of outputs. Older implementations, as per earlier
versions of the spec use 2 (not used in the default count
mode).
|
Channel interpretation | "discrete" |

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.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 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.
