HTML5 provides a standard for playing audio files.
Audio on the Web
Until now, there has not been a standard for playing audio files on a web page.
Today, most audio files are played through a plug-in (like flash). However, different browsers may have different plug-ins.
HTML5 defines a new element which specifies a standard way to embed an audio file on a web page: the <audio> element.
How It Works
To play an audio file in HTML5, this is all you need:
Example
<!DOCTYPE html>
<html>
<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>
Try it yourself in Notepad or Dreamweaver by coping and pasting the code above.
The control attribute adds audio controls, like play, pause, and volume.
You should also insert text content between the <audio> and </audio> tags for browsers that do not support the <audio> element.
The <audio> element allows multiple <source> elements. <source> elements can link to different audio files. The browser will use the first recognized format.
Audio Formats and Browser Support
Currently, there are 3 supported file formats for the <audio> element: MP3, Wav, and Ogg:
| Browser | MP3 | Wav | Ogg |
|---|---|---|---|
| Internet Explorer 9 | YES | NO | NO |
| Firefox 4.0 | NO | YES | YES |
| Google Chrome 6 | YES | YES | YES |
| Apple Safari 5 | YES | YES | NO |
| Opera 10.6 | NO | YES | YES |
HTML5 audio Tags
| Tag | Description |
|---|---|
| <audio> | Defines sound content |
| <source> | Defines multiple media resources for media elements, such as <video> and <audio> |
