Creating a Podcast with GarageBand on a Macintosh
GarageBand, part of Apple's iLife suite, puts you in the control room of your own digital full-featured radio station. You can add a podcast artwork track just by dragging in images to the timeline to correspond with your audio track. You can also add jingles and sound effects from the built-in library that comes with GarageBand. Automatic "ducking" decreases the audio level of the music when you begin talking so your audience can always hear you speak. You can use iChat as a source for recording interviews for your podcast even if your guest is on the other side of the world! This tutorial will get your up and running with GarageBand in no time. GarageBand is available on the Mac lab computers.
