Although there are numerous professional podcasting software packages currently available ($100 - $1000+), beginning podcasters may want to start with a freeware program. One of the most widely used free podcasting software programs is Audacity (http://audacity.sourceforge.net/), an open source sound recording and editing program with versions available for PC, Mac, and Linux operating systems. For Mac users another free podcasting program is GarageBand, found within the iLife package that comes with all new Mac OS X computers. Although older versions of GarageBand do not have the podcasting function, upgrades to the new, podcasting-ready GarageBand 4.1 are available in the iLife08 package for $90 (educational discounts available; http://www.apple.com/ilife/garageband/). For specific instructions on using GarageBand, an online video tutorial is available from Apple at http://www.apple.com/ilife/garageband/.
