DelayNode: DelayNode() constructor

Syntax

new DelayNode(context)
new DelayNode(context, options)

Parameters

context

A reference to an AudioContext or OfflineAudioContext.

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 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.channelCount for more information.) Its usage and precise definition depend on the value of channelCountMode.

channelCountMode

Represents an enumerated value describing the way channels must be matched between the node's inputs and outputs. (See AudioNode.channelCountMode for 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". (See AudioNode.channelCountMode for 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,
});
