Podcasting Preparing the MP3 File Creating an RSS Feed Validating and Publishing the Feed
Podcasting Defined Podcasting is the distribution of specially encoded multimedia content (normally MP3 files with ID3 tags) to subscribed personal computers via the RSS 2.0 protocol. RSS 2.0 protocol It is a form of narrowcasting, which sends content to people who have decided to listen, as opposed to broadcasting, which goes to everyone within a certain radius of the signal.
Podcasters versus Podcatchers Podcasters are the people who create the content. Podcatchers are those who listen to the content.
Potcatching Clients The first podcatching client was iPodder, created by Adam Curry, the former MTV VJ. iPodder is now called Juice Receiver and is freely downloadable from juicereceiver.sourceforge.net.juicereceiver.sourceforge.net Juice Receiver is a so-called aggregator that accesses the podcasts to which you have subscribed, retrieves any enclosed multimedia content, manages files for iTunes and iPhoto, and deletes old podcasts from your hard drive after they have expired.
iTunes The most popular podcasting client is iTunes, which is available for both Macintosh and Windows. You download iTunes from www.apple.com/itunes.www.apple.com/itunes
Recording the MP3 File You can use any audio recording software you prefer to record the MP3 file. Audacity is a free, cross-platform (i.e., Mac and Windows) audio editor available from audacity.sourceforge.net. audacity.sourceforge.net iTunes can convert a wide range of audio formats into the MP3 format.
ID3 Tags ID3 tags enable MP3 players to display information about the file, such as: Name Artist Album Track Number Year Composer Genre Comments
