Up to now, playing audio in a web browser has been a bit of a black art. Traditionally there are several ways to embed a sound in a web page — some work better than others, and many only work if you happen to be using the right browser with the right plugin.
The ubiquity of the Flash plugin has helped to a large extent, since Flash makes it easy to embed audio in a way that works with most browsers. However, this doesn’t help with browsers such as Safari on the iPhone and iPad, which don’t support Flash at all.
In short, it’s all a bit of a mess.
Fortunately, HTML5 looks set to make life easier for us developers, thanks to its audio element. This element lets you embed an audio file in a web page, as well as control playback of the sound using JavaScript. More importantly, it doesn’t require any plugin to work, and is supported by nearly all modern web browsers. (We’ll come back to browser support later!)
In this tutorial I’ll show you how to embed sounds in a page with the audio element. We’ll also take a look at how to trigger and stop the audio via JavaScript, and how to ensure our audio can play on as many web browsers as possible.
