NEW YORK (UPI) -- The cost to create podcasts via a home computer can be minimal for amateur U.S. podcasters, but extras can cost as much as $30,000. Citizen podcasts are as varied as their creators -- from recordings of family reunions, neighborhood walking tours standup comedy routines -- and can be found via a Goggle search under by topic, or by using a podcast directory like those on Yahoo or iTunes, the New York Times reported Sunday. The cost can run from $10 for a microphone -- and some computers have one built-in -- or as much as $30,000 for a well-equipped recording studio. "But all you really need to get started is a software program to record audio," said Lisa Williams, a writer and mother of two in Watertown, Mass., who podcasts a tutorial on podcasting at itconversations.com/shows/detail626.html. "Podcasts with a little background noise aren't bad -- they have their own rugged charm."
