HTML5 Audio
HTML5 provides a standard for playing audio.
Audio on the Web
Until now, there has never been a standard for playing audio on a web page.
Today, most audio are played through a plugin (like flash). However, not all browsers have the same plugins.
HTML5 specifies a standard way to include audio, with the audio element.
The audio element can play sound files, or an audio stream.
To play an audio file in HTML5, this is all you need:
</audio>
The control attribute is for adding play, pause, and volume controls.
Insert content between the <audio> and </audio> tags for browsers that do not support the audio element:
<audio src=”song.ogg” controls=”controls”>
Your browser does not support the audio element.
</audio>
The example above uses an Ogg file, and will work in Firefox, Opera and Chrome.
To make the audio work in Internet Explorer and Safari, add an audio file of the type MP3.
The audio element allows multiple source elements. Source elements can link to different audio files. The browser will use the first recognized format:
<source src=”song.ogg” type=”audio/ogg” />
<source src=”song.mp3″ type=”audio/mpeg” />
Your browser does not support the audio element.
</audio>
