Podcasting is one of those multimedia terms that means different things to different people. The most simple definition is that it’s an audio file—most commonly an MP3 file—distributed by way of the Web.
Distribution can be passive—the audio file sits on your Web site—or it can be more active—the file can be pushed to a listener by way of an RSS feed.
The “cast” part of podcasting reminds us of “newscast,” but podcasts can be created for training, marketing, or any other kind of information you create.
The more disposable your use, the more streamlined you’ll want your production process.
If the highest priority is to quickly turn around the podcast, you might not want to invest time editing out “ums” or other stumbling.
If your podcast will have a longer shelf life, cleaning it up with editing will make it easier to listen to.
Media production is a collaborative process. Phases of production will probably involve different staff during the different stages:
Franklin McMahon at Creative Cow has and excellent three-part series podcast creation. (Note when you arrive at Creative Cow, you'll need to scroll down and click on the image to launch the tutorials.)
MP3 is a compression algorithm for audio. The more you compress your audio, the more clarity and richness it loses.
But because you’re distributing by way of Web, file size matters in how convenient it will be to download. You'll have to strike a balance between quality of sound and quality of download.
The way to make your file size smaller is to lower the data rate. For most basic podcasts—voice with a little music—a data rate of 64 kbps is adequate. It’s possible to go as low as 32 kbps.
You can compensate for some loss of quality by manipulating the audio’s dynamic range and EQ settings (more on this subject in the future).
If your listeners hear the podcast straight from your Web page, distribution is straightforward. If your listeners will download the podcast to an MP3 player, your job becomes a little more complicated. This area of the podcast page is being developed by a collaborative conversation of Munigov 2.0 members. More to come on this subject soon. (July 6, 2009)
If you can hook your audience with an intriguing opening, they're likely to continue listening. Your podcast introduction should include speaker introductions, identification of the producer or sponsoring organization and its location.
If your podcast follows an interview format, remember to use open-ended questions to avoid answers of merely "yes" or "no."
If your podcast is scripted, then
If you think your audience is multitasking while listenting to your podcast, then write appropriately. A Canadian Broadcasting Company radio producer once suggested a "tying your shoes rule." Someone listening to your story should be able to understand it while tying her shoes. Long clauses and phrases are even less acceptable when your audience multitasks!
If you add music, make sure you have copyrights to it. Music is available from different royalty-free sources such as www.iStockphoto.com and www.digitaljuice.com
If you record in your office at your computer, then here are some reminders:
Headset microphones can cause problems with popping "Ps" and sibilance because the mic is so close to your mouth. If you can use a microphone that allows distance from your mouth, put it at a distance of five open fingers, and put it at a slight angle from your mouth. Distance and the angle help minimize popping.
A common problem with recorded narration is that people begin sentences with greater energy and then fade. Try to keep your vocal energy consistent. Rehearsing helps. Smiling helps, too.
