AudioNodeOptions

Web Audio API 的 AudioNodeOptions 字典指定了创建新 AudioNode 对象时可使用的选项.

AudioNodeOptions 继承自不同类型的音频节点构造函数的选项对象. 例如 AnalyserNode.AnalyserNode 或 GainNode.GainNode (en-US).

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 (en-US) 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 (en-US) 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". (See AudioNode.channelCountMode (en-US) for more information including default values.)
