I am a software engineer, and unfortunately people know it. So I get those inevitable computer questions. This time it is a relatively simple one I think, but one for which I have no experience.
How can I create and publish podcasts?
Any solution should be first and foremost easy for a novice computer user to go from start to finish without additional help. If software is required, it should be reasonably priced or free.
Edit: The user has access to both Windows and OSX.
Audacity is the canonical answer for free audio software.
There is a list of pod producing software here (german, but the links will work for you, I think)
I have not used it myself, but know of people having success with PodcastMaker for the Mac.
