This is the first of a series of podcasts that, if you follow along, will get you to the point where you've made a podcast of your own. This episode talks about some really cool (freeware) digital audio software called Audacity. If you actually dig in and follow the steps you should have recorded some digital audio by the end. And even if you don't go through all the hoops I hope you learn a little bit about how to do digital recording.
Audacity software can be found at http://audacity.sourceforge.net/
