AudioDestinationNode.maxChannelCount
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.
Syntax
var audioCtx = new AudioContext(); var myDestination = audioCtx.destination; myDestination.maxChannelCount = 2;
Value
An unsigned long.
Example
The following would set up a simple audio graph, featuring an AudioDestinationNode with maxChannelCount of 2:
var audioCtx = new AudioContext(); var source = audioCtx.createMediaElementSource(myMediaElement); source.connect(gainNode); audioCtx.destination.maxChannelCount = 2; gainNode.connect(audioCtx.destination);
