DelayNode: DelayNode() constructor
The DelayNode()
constructor of the Web Audio API
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.
Syntax
new DelayNode(context)
new DelayNode(context, options)
Parameters
context-
A reference to an
AudioContextorOfflineAudioContext. optionsOptional-
An object specifying the delay node options. Can contain the following members:
delayTime-
The initial delay time for the node, in seconds. The default is
0. maxDelayTime-
The maximum delay time for the node, in seconds. Defaults to
1. channelCount-
Represents an integer used to determine how many channels are used when up-mixing and down-mixing connections to any inputs to the node. (See
AudioNode.channelCountfor more information.) Its usage and precise definition depend on the value ofchannelCountMode. channelCountMode-
Represents an enumerated value describing the way channels must be matched between the node's inputs and outputs. (See
AudioNode.channelCountModefor more information including default values.) channelInterpretation-
Represents an enumerated value describing the meaning of the channels. This interpretation will define how audio up-mixing and down-mixing will happen. The possible values are
"speakers"or"discrete". (SeeAudioNode.channelCountModefor more information including default values.)
Return value
A new DelayNode object instance.
Examples
const audioCtx = new AudioContext();
const delayNode = new DelayNode(audioCtx, {
delayTime: 0.5,
maxDelayTime: 2,
});
