interface represents an integer used to determine how many channels are used when up-mixing and down-mixing connections to any inputs to the node.
channelCount
's usage and precise definition depend on the value of AudioNode.channelCountMode
:
- It is ignored if the
channelCountMode
value ismax
. - It is used as a maximum value if the
channelCountMode
value isclamped-max
. - It is used as the exact value if the
channelCountMode
value isexplicit
.
Syntax
var oscillator = audioCtx.createOscillator(); var channels = oscillator.channelCount;
Value
An integer.
Example
var AudioContext = window.AudioContext || window.webkitAudioContext; var audioCtx = new AudioContext(); var oscillator = audioCtx.createOscillator(); var gainNode = audioCtx.createGain(); oscillator.connect(gainNode); gainNode.connect(audioCtx.destination); oscillator.channelCount;
