To begin with, the requirements for creating an 'article' (music project) are simple: first, only free licensed content can be uploaded. Second, it's best if you can upload both the 'mixed' version of the piece and the piece in its individual components, or 'tracks', hence why they are known as 'multitracks'. Of course, you don't need to worry about that if your audio is only one track (and don't worry if it is; a project can start off as small or as big as you want it to be) - multitracks just make it easier for others to modify or expand on your work. Your music can be uploaded to a page using the "Upload image/file" link in the toolbox on the left-hand side of the page.
There are pretty much three formats you can use for your music on this Wiki. The first, and most universally usable, is MP3. While it is also arguably the worst, using it will ensure that everyone can work with your music. The other two formats are FLAC (Free Lossless Audio Codec), a 'perfect' quality format, or Ogg. To find out more about the different audio formats and which you should choose, check out this guide.
Starting a project page Edit
On the page you create, add any description about the audio and include the date you uploaded it, along with your uploaded media (information below). In particular, try to include information that could be useful to people messing with your audio, like BPM or key signature. When adding your own alterations/changes to someone else's project, first upload the audio (process described below), then add a section to the main project page with the link to the audio content that you separate from the rest of the page with a header tag (include the name in between two equal signs, like this: == name/description == ). Also, include the date you uploaded the material, and any comments or description you'd like to make about your changes. You can include requests in that text (for example, "could someone create a violin line for the bridge on this track at around 1:15"). Then, other users can add any of their own comments or suggestions below your description by editing the page, adding their text after the description, and indenting it with a bullet by putting a colon and an asterisk before the text, :*like this
- If you're ready to create a new project page, enter its title in the box below and submit it.
Uploading and downloading Edit
The 'toolbox' on the left side of each page includes a link named 'Upload file'. Use this tool to upload your audio to the wiki. Keep in mind that the wiki software will only accept MP3, FLAC, and Ogg audio files. Also, if it applies to you, you can upload MIDI sequences (.mid files), so if you've programmed a killer drum track or piano line in MIDI, you can upload that sequence and others can take it, mess with it, use it with different software instruments or samples, etc.
If you would like to upload other kinds of files (zipped multitracks, GarageBand files, etc.), feel free to upload them to the file hosting service of your choice and then link to those files from your project page.
Feel free to ask any questions for clarification or make any comments on the discussion page for this article if anything isn't clear.
