ChannelMergerNode: ChannelMergerNode() constructor

The ChannelMergerNode() constructor creates a new ChannelMergerNode object instance.


new ChannelMergerNode(context)
new ChannelMergerNode(context, options)



A BaseAudioContext representing the audio context you want the node to be associated with.

options Optional

An object defining the properties you want the ChannelMergerNode to have:

numberOfInputs Optional

A number defining the number of inputs the ChannelMergerNode should have. If not specified, the default value used is 6.

channelCount Optional

An integer used to determine how many channels are used when up-mixing and down-mixing connections to any inputs to the node. (See AudioNode.channelCount for more information.) Its usage and precise definition depend on the value of channelCountMode.

channelCountMode Optional

A string describing the way channels must be matched between the node's inputs and outputs. (See AudioNode.channelCountMode for more information including default values.)

channelInterpretation Optional

A string describing the meaning of the channels. This interpretation will define how audio up-mixing and down-mixing will happen. The possible values are "speakers" or "discrete". (See AudioNode.channelCountMode for more information including default values.)

Return value

A new ChannelMergerNode object instance.


InvalidStateError DOMException

Thrown if an option such as channelCount or channelCountMode has been given an invalid value.


const ac = new AudioContext();

const options = {
  numberOfInputs: 2,

const myMerger = new ChannelMergerNode(ac, options);
