So what’s all this “podcast” stuff? Anyway? It sounds like the invasion of the Pod People! Well – to put it quite simply, a
podcast is any audio content in the form of an MP3 file that can be delivered automatically to your computer or to your MP3 player. You
don’t have to have an iPod or any particular brand of MP3 player; for that matter, you
don’t have to have an MP3 player at all. You can just play the file on your computer, using the Windows Media Player, RealAudio Player, QuickTime Player, WinAmp, or whatever MP3-playing software happens to be your favorite. Windows, Macintosh, Linux, BeOS – makes no difference!
How is a podcast different from the streaming Internet Radio that’s been around on the web since the mid ‘90s? It’s quite simple… to listen to the Internet Radio feed you have to be there, at your computer,
while it’s happening. You can’t save it for later and you can’t take it with you. A podcast has been recorded by the podcaster and saved as an MP3 file which is then automatically sent to your computer for you to listen to
when and where you’re ready to listen to it. You control when you’re going to listen to it, and whether you will listen on your computer or on your MP3 player. Since so many people use iPods as their MP3 players, the name
podcasting was just kind of inevitable.
So how do you get these podcasts coming into your computer? The answer lies in software called a podcast
aggregator; what many people call a
podcatcher. A podcatcher is just a program that lives on your computer. Its job is to maintain a list of podcasts which you have given it and check the Internet sites where those podcasts live; you decide how often it should check for you (it could check every half hour, for example, or just once each day). When it finds a new show listed at that site, it will download it automatically for you and put it into a folder which you have specified. You tell it which shows to check by
subscribing to them. Don’t be confused by this term; “subscribing” in this sense just means that you’ve set up your podcatcher to receive the
RSS feed from that site and to automatically download any new shows that it finds posted there. (An RSS feed, in simple terms, is a specialized Web page, living at the site that publishes the podcast, that tells your podcatcher where to find the MP3 files.) There is seldom any actual cost involved in receiving a podcast, since most are free; only a handful at this time request a payment from their listeners, and
simply “subscribing” through your podcatcher is always free.
As of today, the three most common podcatchers are
iPodder Lemon,
iPodderX, and
iTunes. iPodder Lemon and iTunes are free; iPodderX offers a free 30-day trial; if you want to use it after that time the cost is $24.95.
Once you have your podcatcher installed, all that’s left is to find some podcasts that you like and subscribe to them… how about starting with the Dark Asteroid Radio Program?! Find the menu item for subscribing to a new podcast, and enter the URL of the program:
http://feeds.feedburner.com/DarkAsteroidRadioProgram and start enjoying the show!
Wanting to find others? Well… there
are a lot! The
Rocky Mountain News for September 23, 2005 reported that iTunes as of that date listed 15,000 podcasts and was adding new ones to the list at the rate of 1,000 a week. Podcast Alley, another popular podcast directory, has more than 7,000 podcasts listed, with at least 400 waiting for approval. With those kinds of numbers, it’s nice to have some kind of directory to help you look. Here are three the Dark Asteroid personally likes, along with the information from their sites’ front pages.
