I came across by chance in what I consider one of the more comprehensive guide to creating audio in Linux, and Stefano gave me the permission to republish his material that I consider really good and that he uses as musician.
Stefano it’s an Ubuntu user and his guide it’s based on this distribution, he’s really active in the Ubuntu italian community, if you want to make him a question regarding his guide, you can post in this thread http://forum.ubuntu-it.org/index.php/topic,278719.0.html, the language of the forum is Italian, but i’m sure that you’ll get some answers also if you ask kindly in English.
You can find the previous part here :

The original article is in italian, you can send note about the Translation to me.
