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);
