HTML <audio> Tag

The <audio> has been added to HTML5 to allow embedding audio files to a web page. Since not all browsers support all audio formats, the audio file is encoded using special codecs.

The <source> tag or the src attribute is used to indicate the variations of the same audio file. The path to an audio file can contain an absolute or relative URLs.

Syntax

The <audio> tag comes in pairs; the content is written between the opening (<audio>) and the closing (</audio>) tags.

<audio>
  <source src="URL" >
  <source src="URL" >
</audio>

Example
