AudioDestinationNode: maxChannelCount property
The maxchannelCount
property of the AudioDestinationNode
interface is an unsigned long
defining the maximum amount of channels that the physical device can handle.
The AudioNode.channelCount
property can be set between 0 and this value (both included). If maxChannelCount
is 0
, like in OfflineAudioContext
, the channel count cannot be changed.
Value
An unsigned long
.
Examples
The following would set up a simple audio graph, featuring an AudioDestinationNode
with maxChannelCount
of 2:
js
const audioCtx = new AudioContext();
const source = audioCtx.createMediaElementSource(myMediaElement);
source.connect(gainNode);
audioCtx.destination.maxChannelCount = 2;
gainNode.connect(audioCtx.destination);
