The AudioNodeOptions
dictionary of the Web Audio API specifies options that can be used when creating new AudioNode
objects.
AudioNodeOptions
is inherited from by the option objects of the different types of audio node constructors. See for example AnalyserNode.AnalyserNode
or GainNode.GainNode
.
Syntax
var audioNodeOptions = { "channelCount" : 2, "channelCountMode" : "max", "channelInterpretation" : "discrete" }
Properties
channelCount
Optional- 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 ofAudioNodeOptions.channelCountMode
. channelCountMode
Optional- 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
Optional- 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"
. (SeeAudioNode.channelCountMode
for more information including default values.)
