AudioNode: channelCount property
Baseline
Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.
The channelCount property of the AudioNode 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
channelCountModevalue ismax. - It is used as a maximum value if the
channelCountModevalue isclamped-max. - It is used as the exact value if the
channelCountModevalue isexplicit.
Value
An integer.
Examples
js
const audioCtx = new AudioContext();
const oscillator = audioCtx.createOscillator();
const gainNode = audioCtx.createGain();
oscillator.connect(gainNode);
gainNode.connect(audioCtx.destination);
oscillator.channelCount;
