For audio files, we strongly support the open-source format Ogg Vorbis, which does not require proprietary software to record or play. You can embed and play OGG files directly from any Wikia page by adding a link to the file like this:
Advent 1

If the OGG player extension is enabled this will cause a simple music player to appear on the page. If not, please contact us to activate the extension for your wiki.
