The following is an example of a simple enclosure for one MPEG audio file for RSS 2.0 feed:
<enc:Enclosure
enc:url="http://www.crocodile.org/sounds/matrosi.mp3"
enc:length="1939570"
enc:type="audio/mpeg" />
The following example shows two unrelated audio enclosures. They will be played in order they appear.
<enc:Enclosures kind="mixed">
<enc:Enclosure
enc:url="http://www.crocodile.org/sounds/matrosi.mp3"
enc:length="1939570"
enc:type="audio/mpeg" />
enc:Content-ID="foo1@bar.net" />
<enc:Enclosure
enc:url="http://www.crocodile.org/sounds/ya_segodnya_smeus_nad_soboi.mp3"
enc:length="1691400"
enc:Content-ID="foo2@bar.net"
enc:type="audio/mpeg" />
</enc:Enclosures>
An example of composite enclosure for audio files in several alternate formats (with ``MP3'' being default and most preferable and ``WAV'' least preferable). Some of files are offered via BitTorrent protocol for download. One file is distributed from two servers, one in US and one in Ukraine. Please note that most preffered format is ``mp3'' downloaded via BitTorrent.

The following example, in addition to providing an audio file in multiple alternative formats, also specifies an image (artist photo) which should be shown simultaneously with audio playback:
