If you are new to podcasting and want to get in some practice with recording audio, as in working with a microphone and editing audio. You can volunteer at librivox.org. That’s l-i-b-r-i-v-o-x.org. You will read and record free public domain audiobooks that are distributed for free over the web. It’s also a good way to get some practice with annunciation and practice your breathing. Take it from me, there is nothing worse than constantly sounding like you’re breathing heavily into the mic or trying to catch your breath.
