We're looking for a person or people to help audit MDN to find places we could speed up. Is this you or someone you know? Check out the RFP: https://mzl.la/2IHcMiE


The delayTime property of the DelayNode interface is an a-rate AudioParam representing the amount of delay to apply.

delayTime is expressed in seconds, its minimal value is 0, and its maximal value is defined by the maxDelayTime argument of the AudioContext.createDelay() method that created it.


var audioCtx = new AudioContext();
var myDelay = audioCtx.createDelay(5.0);
myDelay.delayTime.value = 3.0;

Note: Though the AudioParam returned is read-only, the value it represents is not.


An AudioParam.
