This is a lovely Audacity tutorial by Tim Brooks. Nicely paced video tutorials that will help you get started painlessly, and a few tips and tricks for experienced users too.
For language learners, it's definitely worth taking the time to set this up on your computer so that you can record yourself speaking offline and listen back. Try shadow reading (http://bit.ly/IXj5eX) and record yourself with Audacity.
