var delayNode = new DelayNode(context); var delayNode = new DelayNode(context, options);
Parameters

dictionary.
- context

orOfflineAudioContext
. - options Optional
- An object specifying the delay node options. Can contain the following members:
delayTime
: The initial delay time for the node, in seconds. The default is0
.maxDelayTime
: The maximum delay time for the node, in seconds. Defaults to1
.
Return value
