One of the most exciting and long-awaited features in HTML5 is the <audio> element, enabling native audio playback within the browser. Today most of the audio are played through a plugin (like flash).
But most developers and designers would agree that it's better not to rely on a plugin at all. HTML5 specifies a standard way to include audio, with the audio element.
HTML5 Audio Formats
In HTML5 there are 3 formats supported for the audio element:
- Ogg Vorbis = This format will work in Firefox, Opera and Chrome only.
- MP3 = MP3 audio file support Chrome and Safari.
- Wav = The Wav format will work in Firefox, Opera and Safari.
Currently, the HTML5 defines five attributes for the audio element:
- Autoplay = A boolean specifying whether the file should play as soon as it can ready.
- Controls = Specifying whether the browser should display its default media controls.
- Loop = It specifying whether the file should be repeatedly played.
- Preload = Specifies that the audio will be loaded at page load, and ready to run. If autoplay is present just ignore it
- Src = a valid <abbr>URL</abbr> specifying the content source.
As video element work in HTML 5, if you want to play an audio file simply add control attribute for adding play, pause, and volume controls. Lets see an example:
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=windows-1252">
<title>New Page 1</title>
</head>
<body>
<audio controls="controls">
<source src="song.ogg" type="audio/ogg" />
<source src="song.mp3" type="audio/mpeg" />
Your browser does not support the audio element.
</audio>
</body>
</html>
Internet Explorer 8 does not support the audio element also. In IE 9, there will be support for audio element.
Although HTML5 audio is a relatively immature part of the standard, if recent trends continue and users upgrade to the latest versions of Safari, Firefox, Chrome and Opera, browser support is likely above 30% today.
