MediaStreamAudioDestinationNode()

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

Syntax

new MediaStreamAudioDestinationNode(context, options);

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: Represents 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: Represents an enumerated value describing the way channels must be matched between the node's inputs and outputs. (See AudioNode.channelCountMode for more information including default values.)
channelInterpretation: Represents an enumerated value 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.)

var ac = new AudioContext();

var myDestination = new MediaStreamAudioDestinationNode(ac);
