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.
DelayNode()
Syntax
new DelayNode(context); new DelayNode(context, options);
Parameters
- context
-
A reference to an
AudioContextorOfflineAudioContext. - 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. -
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. (SeeAudioNode.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. (SeeAudioNode.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, });
