AudioNodeOptions

在此页

AudioNodeOptions dictionary of the Web 音频 API specifies options that can be used when creating new AudioNode 对象。

AudioNodeOptions is inherited from by the option objects of the different types of audio node constructors. See for example AnalyserNode.AnalyserNode or GainNode.GainNode .

var audioNodeOptions = {
  "channelCount" : 2,
  "channelCountMode" : "max",
  "channelInterpretation" : "discrete"
}

channelCount 可选: 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 AudioNodeOptions.channelCountMode .
channelCountMode 可选: 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 可选: 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" 。(见 AudioNode.channelCountMode for more information including default values.)
