Ars Technica has posted a nice review & tutorial on how to edit audio on the Linux platform. It compares three audio softwares: Ardour, Audacity and SND which are different from other audio programs on other platforms because "when editing in a proprietary environment, a choice of software to a large extent determines possible choices of hardware and vice versa. Once a platform has been chosen it defines what can be done and how it will be done, because the code is finished and closed. To a great many people, indeed the vast majority, this is the preferred method to work because it is convenient." Pretty much stating if you want to work on the Linux platform you have to be somewhat of a geek.  "An open system is fundamentally different. FOSS software is, almost by definition, a work in process. If Ardour doesn't have a feature I need, I can code it myself. With this possibility, the software no longer defines what I can do—it's just a point of departure." Not for me me but it should interest some of you (I am looking at you Chris).
