HTML Audio – How It Works
The controls attribute adds audio controls, like play, pause, and volume.
The <source> element allows you to specify alternative audio files which the browser may choose from. The browser will use the first recognized format.
The text between the <audio> and </audio> tags will only be displayed in browsers that do not support the <audio> element.
HTML <audio> Autoplay
To start an audio file automatically, use the autoplay attribute:
Example
<audio controls autoplay>
<source src=”horse.ogg” type=”audio/ogg”>
<source src=”horse.mp3″ type=”audio/mpeg”>
Your browser does not support the audio element.
</audio>
