AudioNode.channelCount

channelCount's usage and precise definition depend on the value of AudioNode.channelCountMode:

• It is ignored if the channelCountMode value is max.
• It is used as a maximum value if the channelCountMode value is clamped-max.
• It is used as the exact value if the channelCountMode value is explicit.

Syntax

var oscillator = audioCtx.createOscillator();
var channels = oscillator.channelCount;

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;

Value

An integer.
