Most podcasters create their content in MP3 or MP4 audio or video files and upload them, linking to the file in a blog post. Users can then click the link to download the content if they’re not automatically subscribed to the RSS/Atom feed. The problem has never been in getting the content to the web page, but in getting the content to work through the feed systems. WordPress, in most cases, will automatically include new podcasting data in your RSS/Atom feed system. This makes it easy for you to deliver content and for your users to subscribe to that content.
For most people, WordPress 1.5 and above will podcast easily and automatically. When you link to the audio file in a WordPress post using the full URL address, it automatically adds it to the RSS/Atom feed and makes it usable as a podcast. Make sure you use a full address.
Your last step is to put a link to your RSS/Atom feed on your page. By default, the feeds are located at the bottom of your WordPress page. The link should look something like this if you’re using RSS:
If you’re using Atom, the link will look like this:
In earlier versions of WordPress, automated links work for posts only, not for static pages. Because WordPress needs to maintain accurate file size information, if you change a linked file you should be certain to republish the post containing the link. If you’ve linked to a file that for any reason is not fully accessible from your blog, your podcast won’t work properly when it is up because WordPress won’t have the correct file size information.
For Apache servers and others that use the .htaccess file, you’ll need to add a directive to the config file or .htaccess file to get the server to recognize podcast files (m4a and m4b) properly. You can simply add this line to the file you use:
AddType audio/x-m4a .m4a>
A podcast is a form of digital media that consists of an episodic series of audio, video, digital radio, PDF, or ePub files subscribed to and downloaded through web syndication or streamed online to a computer or mobile device. The word is a portmanteau of “Pod” and “broadcast.”
The Merriam Webster Tenth International Collegiate defines “podcast” as: a program (as of music or talk) made available in digital format for automatic download over the Internet.
A podcast’s distributor maintains a list of audio or video files in a series on a server as a web feed, and the listener or viewer uses special client application software, known as a podcatcher, to access this web feed, check it for updates, and download any new files in the series. This process can be automated so that new files are downloaded automatically, which may seem to the user as if the content is being broadcast or “pushed” to them. Files are stored locally on the user’s computer or other device, ready for offline use. Podcasting contrasts with webcasting (Internet streaming), which generally isn’t designed for offline listening to user-selected content.
