I use Audacity to record sound, it's a very familiar interface, what it used to be sound forge, and other sound editors. Ardour also gives you more professional options, I like it, but in the end, audacity hasn't crashed as many times as Ardour has done it on my computer. Good software I just can't use it by now. Besides, audacity comes with a large library of plug-ins, which are very handful.
