HTML5 provides a standard for playing audio files.
Audio on the Web
Before HTML5, there was no standard for playing audio files on a web page.
Before HTML5, audio files had to be played with a plug-in (like flash). However, different browsers supported 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.
Browser Support
Internet Explorer 9+, Firefox, Opera, Chrome, and Safari support the <audio> element.
Note: Internet Explorer 8 and earlier versions, do not support the <audio> element.
HTML5 Audio – How It Works
To play an audio file in HTML5, this is all you need:
Example
<source src=”horse.ogg” type=”audio/ogg”>
<source src=”horse.mp3″ type=”audio/mpeg”>
Your browser does not support the audio element.
</audio>
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 | YES | NO | NO |
| Chrome | YES | YES | YES |
| Firefox | NO Update: Firefox 21 running on Windows 7, Windows 8, Windows Vista, and Android now supports MP3 |
