I thought I would share some information about the hardware we use to create our podcasts. We use an Apple Macintosh iBook, an external microphone and Apple's GarageBand. Our teacher, Avi, reads the material into GarageBand, which allows him to play back and re-record as necessary. He then brings the iBook to me, and I send the podcast to Apple's iTunes software to convert it to .mp3, which I can then post to the Internet.
Even though iBooks have onboard mics which record, we found that the Sennheiser mics have much better recording quality.
Next time: creating a podcast, posting it on the Internet, and submitting to Apple's iTunes store.
