I don't use it much - I'm a midi person really - but for a freebie Audacity is far better than it has any right to be, and is fairly easy to use. However the documentation is rudimentary and I find myself using Google as a supplimentary help engine.

It is usually very stable on my Athlon 3200xp + Windows XP + Soundblaster Audigy Platinum setup, but it does seem picky about effects plug-ins. There are some provided with the package and they are very stable. I have some other "VST" plug-in effects on my PC (sourced from Cakewalk Sonar 2 and Sony Vegas 9 if that's any help) which sometime cause crashes, so I tend to save before using anything "non native".

Side issue for those using Audigy's, I've been using Creative's drivers for the Audigy for about a year, and they are very stable. Previously I was using the "kx" drivers because Creative's drivers (including those provided in the box with the card) were total, freeze-up-the-pc disasters!
