As stated earlier, Ogg is not limited to audio files. While it produces a better quality audio file than MP3, it can also be used for video files as well.
Now that our wiki is ready for us to use audio files, we need to learn how to embed them into our pages. Make sure you have at least one Ogg sound file for this exercise. If not, you can find some at Wikimedia Commons: http://commons.wikimedia.org/wiki/ Main_Page. That is where I found the file Tremolo_Picking.ogg
that I will be using.
To embed a file that has been uploaded, we will be using the [[File]]
wikitext.
1. Using the Upload file link in the toolbox, upload your Ogg file to your wiki.
2. Open a new page for editing. In this example, I created a page called Sound Test.
3. On the page, locate where you wish to place your file and type:
[[File:filename.ogg]]
.4. Click on Show preview.
Your wiki should now show a page similar to the one in the following screenshot:
