The value property of the AudioParam interface represents the parameter's current floating point value, which is initially set to the value of AudioParam.defaultValue.
Though value can be set, any modifications happening while there are automation events scheduled — that is, events scheduled using the methods of the AudioParam — are ignored, without raising any exception.
Syntax
var gainNode = audioCtx.createGain(); gainNode.gain.value = 0; //'gain' is the AudioParam
Value
A float.
Example
var AudioContext = window.AudioContext || window.webkitAudioContext; var audioCtx = new AudioContext(); var gainNode = audioCtx.createGain(); gainNode.gain.value = 0;
