AudioDestinationNode interface represents the end destination of an audio graph in a given context — usually the speakers of your device. It can also be the node that will "record" the audio data when used with an
AudioDestinationNode has no output (as it is the output, no more
AudioNode can be linked after it in the audio graph) and one input. The number of channels in the input must be between
0 and the
maxChannelCount value or an exception is raised.
AudioDestinationNode of a given
AudioContext can be retrieved using the

There is no complex set up for using an
AudioDestinationNode — by default, this simply represents the output of the user's system (e.g. their speakers), so you can get it hooked up inside an audio graph using only a few lines of code:
var audioCtx = new AudioContext(); var source = audioCtx.createMediaElementSource(myMediaElement); source.connect(gainNode); gainNode.connect(audioCtx.destination);
