A podcast is a method of distributing multimedia files, usually (but not limited to) audio in the MP3 format, over the Internet to subscribers. Anybody can be a subscriber--one only needs the proper software to receive the subscription. In this article, the author discusses how to create one's own podcast. Before creating the podcast, one needs a way to record the audio, an appropriate location on the Internet to which one can upload it, and a method for people to find and subscribe to the podcast. Of course, one needs compelling content to record. Two popular software recording programs are the cross-platform program Audacity, a free audio recorder and editor, and Apple's GarageBand (part of the iLife suite). A microphone for your computer--if not already built in--can cost as little as $5 or as much as $150, depending on quality.
