Digital Audio Curriculum

Podcasting, a word derived from the “iPod” and “broadcast,” is a form of audio broadcasting over the Internet. Although it is named after Apple’s iPod, any MP3-compatible media player or gadget can run podcasts, as long as you have subscribed to a particular podcasting show. Once you have downloaded the podcast, it becomes any other MP3.

Anyone can create a podcast on subjects as varied as politics, sports, movie reviews, technology and anything you please. You can share your knowledge about marketing, business, art and other specialization. As long as you have useful content to share, you’ll be surprised about how well people receive the information you produce. Since podcasts are free from radio, broadcasting or corporate regulations, anyone can produce virtually any type of podcast, even if you to go talk show style.

Podcasts were first created by ordinary netizens (net citizens), but now even big media outlets such as Rush Limbaugh and NPR are producing podcasts. The term podcast was credited to former MTV VJ Adam Curry and David Winer. Adam wanted a way for people to create audio content for listeners to receive automatically, while David had the feed technology to make it happen.

6 Things You Should Know about Podcasts

You only need to subscribe to a particular podcast once, and you can wake up each day with new shows to listen from you MP3 player.

2) Podcast/RSS feed – When want a show received by your MP3 player automatically, you subscribe to a podcast feed (or RSS feed). Blogs or websites use this feed to deliver new articles or audio content to subscribed readers/listeners. (You’ll know where to subscribe when you see a little orange icon).

3) No subscription – If you wish to check out a podcast show, but prefer not to receive podcasts automatically, you can download them as an MP3 file or view it on the web. Once you find the podcasts interesting, you can then subscribe to the show.

4) Podcast aggregator – For you to be able to subscribe to any podcasts, you’ll need a podcatcher or a podcast aggregator. It’s a software program used in subscribing and receiving podcasts. This program checks for new audio content and downloads them automatically. When you plug your MP3 to your computer, you’ll see the new podcasts already synced to your media player, such as QuickTime or iTunes. Need a podcast aggregator?

5) Podcast Price – Most podcasts don’t charge a cent and you can subscribe to as many podcasts as you can find. The only limitation you’ll face is the amount of time you have available for listening to the podcasts. However, podcasts are not equally made, so if you encounter a creative and engaging podcast, be prepared to listen to some crappy ones as well.

6) No Commercials or SPAM – The advantage of podcasts over online radios is that most podcasts survive even without commercials. The production of podcasting is low enough for podcasters to provide their audio content to listeners free. Another great thing about podcasts is that no podcast SPAM exist, so you don’t need to filter out junk podcasts. The only downloads you’ll receive are the ones you chose yourself.
