MediaStreamAudioDestinationNode: MediaStreamAudioDestinationNode() constructor

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since April 2021.

The MediaStreamAudioDestinationNode() constructor of the Web Audio API creates a new MediaStreamAudioDestinationNode object instance.

Syntax

js
new MediaStreamAudioDestinationNode(context)
new MediaStreamAudioDestinationNode(context, options)

Parameters

context

An AudioContext representing the audio context you want the node to be associated with.

options Optional

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

channelCount

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

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

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.)

Examples

js
const ac = new AudioContext();

const myDestination = new MediaStreamAudioDestinationNode(ac);
