I gave a workshop on using Audacity sound editing software for creating podcasts in Penn State's College of Agricultural Sciences on September 12. This way to my presentation materials . And this way to some excellent tutorial videos on using Audacity , by Jason Van Orden. These videos provided all the information I needed to get started with Audacity. While GarageBand is my preferred tool for podcasting and informal music recording, Audacity is a respectable open-source alternative.
