This package of codecs lets you play the impressive Ogg Vorbis audio file format within Windows Media Player.

It does a little more than just that, though. Once installed it can be used to split Ogg files into their different Ogg streams, multiplex several Ogg streams into a single file, encode PCM audio to Ogg format, and decode Ogg audio to PCM.

If none of that makes sense then don't worry, because you can simply use it to play Ogg files within Windows Media Player.

This collection can also, apparently, be used to embed most types of video and audio into Ogg streams.
