MDN’s new design is in Beta! A sneak peek:

This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.

The DelayNode() constructor creates a new DelayNode object with a delay-line; an AudioNode audio-processing module that causes a delay between the arrival of an input data, and its propagation to the output.


var delayNode = new DelayNode(context, options)


A reference to an AudioContext.
options Optional
Options are as follows:
  • delayTime: The initial delay time for the node. The default is 0.
  • maxDelayTime: The maximum delay time for the node. The default is 1.
