Listening to Podcasts - Overview

The idea behind Podcasting is actually fairly simple.  There is already have a standard for syndicating text content on the Web, called "RSS" or "Really Simple Syndication".  RSS is used to display headlines and short summaries of stories on your computer.   Example 

Podcasting takes it one step further by allowing content creaters to embed a links to audio files intoan RSS feed.  Listeners can then subscribe to these feeds using an Aggregator such as Itunes.  The Aggregator continually checks those feeds, and downloads any new content to your computer.   You can then transfer those files to your MP3 player or play them on the PC.    See      Itunes pictured below.


Finding Podcasts  example

Creating Podcasts  -

Step One - Create the first Sound file (.mp3)  - See Sound Recording - sidebar

Level One - Sound files (or video file) is created, upload to a Web server then linked to from a Web page.   When clicked, the sound file will play on the computer.  

Two steps to creating a Podcast

  1. Create the Audio file  (.mp3) - See Audacity instructions
  2. Create the RSS Feed (.xml) - See Yahoo instructions and copy .xml file
Sound recording software.
You can use a number of free and paid software programs to record your podcast. Audacity is a popular free program for recording and editing podcasts and it's available for both Windows and Mac.   Audacity instructions   Mac users can also purchase use GarageBand sound recording and editing.

 
Publishing Podcasts
  1. Upload .xml and .mp3 to Faculty Web Server.

Your RSS feed will be the link to the .xml file

Note:   You might want to create a folder on your Faculty Web servers space that will contain your .xml file and all your .mp3 files.  
Updating Podcasts

You can create periodic episodes for your Podcasts by adding items (links to new .mp3 files) to your .xml file.    After you update your .xml file, upload it to your Faculty web server space.  Anyone who has subscribed to your feed will receive the new episode.

Sample
<item> <title>DYSBS Day One</title> <description>Welcome to Day One</description> <itunes:author>Rhonda Berger</itunes:author> <pubDate>Tues, 25 April 2006 15:00:00 EST</pubDate> <enclosure url="http://faculty.mdc.edu/rberger/pod/Dayone.mp3" length="30610" type="audio/mpeg" /> </item>
Advertising/Distributing  your Podcasts

You should create a Web Page that displays your RSS feed file and also links directly to your .mp3 file so it can be played directly from that page.   See sample feed file.
