Podcasting
  What is Podcasting?
    According to Wikipedia, “A podcast is a web feed of audio or video files placed on the Internet for anyone to download or subscribe.” Podcasting, in its pure sense, is intimately connected to syndication, where the user subscribes to an on-line service that periodically sends, or pushes, pertinent information to the user. Nearly analogous to a television broadcast sending information to a television or a radio broadcast sending information to a radio, a podcast sends information to an iPod.
    The term “podcast” is derived from Apple Computer’s ubiquitous MP3 player called the iPod. This implies that podcasting is a mobile thing; you download and listen to a podcast via your MP3 player. While this scenario is very popular it’s not the only way to listen to a podcast, you can listen to podcasts through your personal computer as well. Also, you do not necessarily need an Apple iPod, MP3 players are available from may other manufactures.
  I want to Podcast, what do I need?
    Podcasting sources come in several forms; the most common is a directory. A directory is a web site that lists the sources for podcasts, examples include Podcast Alley and iTunes Music Store. These sites normally connect users with syndicated information, like general news or sports, or more targeted information like books, business, entertainment and health (just to name a few). Once you’ve chosen a podcast you’ll nee to add it to your podcatcher.
   
    A podcatcher is a piece of software that’s installed on your personal computer, and provides a mechanism for downloading, storing, organizing and playing your podcasts. One of the most valuable features of a podcatcher is the ability to automatically check a podcasting source for new content. When new content is found, the podcatcher saves the information in preparation to be uploaded or “synced” to the MP3 player the next time it is connected to your personal computer. There are a number of podcatchers, some free programs are Juice, Transistr (available March 2006) and iTunes.
    MP3 players rely on the manufacturer’s software provided with the device for uploading information to the respective MP3 player. The Apple iPod has iTunes, Creative Labs has MediaSource and iRiver has iriver Music Manager.
    Your MP3 Player is the final destination. MP3 players are normally connected to your personal computer via a USB (Universal Serial Bus) connection. Once your MP3 player is connected, it will compare what’s in your podcatcher to what’s on the MP3 player and attempt to “sync” the two. This is normally a unidirectional transfer of data, from the podcatcher to the MP3 player. Once “synced,” the MP3 player can be disconnected from you personal computer. Now the user is ready to listen (or view) the newly downloaded content.
    Earlier the podcasting process was compared to a television and radio broadcasts, obviously it a little more involved. Regardless, the benefits include content on demand, convenience, portability and greater control over what podcasts or vodcasts (video podcasts) you listen to, or watch.
  Subscribing to a Podcast
   

Subscriptions to podcasts are facilitated via your podcatcher software. Simply put, you copy and paste a link into your podcatcher software. You can find podcasting links from one of the podcasting directories, on a web site or even via a friend.

    Note: Podcasting is based on RSS or Real Simple Syndication. RSS feeds are formatted using XML (Extensible Markup Language), so it’s not uncommon to see an RSS link end with the file extension of xml.
    A sample RSS (podcast) link: http://www.nd.edu/~cba/rss/deansWelcome.xml
    All Podcatcher software will have a “Subscribe” menu item, you select it, a window will pop-up where you can either type in or paste a podcast link, select “OK” and your done.
  How do I Create a Podcast?
   

Both software and hardware are required to create a acceptable podcasting file. On the software side you'll need a "production" program, one that can both record, import, export and edit a variety of formats, including WAV, AIFF MP3 and OGG. Hardware, in it's simplest from, includes an input device, usually a microphone (or digital camcorder for video), and a storage device, normally your computer. For both software and hardware, "the sky's the limit," as far as cost and features - all the way up to a recording studio. Regardless, one can produce a functional podcast using reasonable priced tools. Some are free, like the Audacity sound editing software.

Andrei Khmelev has created an excellent presentation entitled "How to Create a Sound File." It's an step-by-step, eleven page "cookbook" that guides you through the process of creating a podcast-ready audio file.

Obviously, the process of creating an audio, or video, file is just one part of the podcasting equation. We continue to scour the intranet for more and better information concerning podcasts. CNET has a very good tutorial called "Create your own podcast." This tutorial is targeted towards the creation of an audio podcast. Whether you're creating an audio or video podcast, there are similarities, like hosting and pre-production planning, and differences, like hardware and editing software.

We will be updating this section as more information becomes available. It might be behooving to start with an audio podcast, and get the process down prior to moving to a video podcast. Conversely, if you either have an existing video file, or you have the necessary equipment and experience, then a video podcast might make sense.
