Setting the granularity of the HTML5 audio event ‘timeupdate’

It should be noted that you can read the currentTime property of a video much more often. If time is really critical, and you can live with a little bit of uncertainty, you can try this instead.

It is, however, a lot less elegant than using the tag’s own timeupdate event.

setInterval(function () {
    console.log(audio.currentTime); // will get you a lot more updates.
}, 30);

In this case, you’ll have to manage the interval yourself, make sure that you clear it before nulling the audio element. But it is a possibility.

I’m using this approach on a video element, but it should apply here, too.
