The currentTime
read-only property of the AudioContext
interface returns a double representing an ever-increasing hardware timestamp in seconds that can be used for scheduling audio playback, visualizing timelines, etc. It starts at 0.
Syntax
var audioCtx = new AudioContext(); console.log(audioCtx.currentTime);
Value
A double.
Example
Note: for a full Web Audio example implementation, see one of our Web Audio Demos on the MDN Github repo, like panner-node. Try entering audioCtx.currentTime
into your browser console.
var AudioContext = window.AudioContext || window.webkitAudioContext; var audioCtx = new AudioContext(); // Older webkit/blink browsers require a prefix ... console.log(audioCtx.currentTime);
