You will need to have software downloaded on your computer to record your audio, edit,and convert the file to a format required by iTunes U. Different types of software are described, based upon the type of podcast you plan to produce.
1. Audio Podcasts
AudacityOne of the best free, open-source audio recording/editing programs is Audacity.
It's easy to use and works on Mac, Windows, and Linux operating
systems. You'll also need to download an mp3 encorder (called LAME) to
convert your Audacity file to mp3 for uploading to iTunes U. Here are
the links for downloading Audacity and the LAME encoder:
Audacity has online tutorials, and it is a very simple program to learn how to use:
Creating a Simple Voice & Music Podcast with Audacity
will probably spend a few hours at first learning how to use Audacity and
then more time learning how to use all of its features. We will hold workshops on using Audacity to make this easier for you. Also,
remember, you don't HAVE to edit your recording, but you may WANT to,
just to make it sound more professional and to add intro and outro music. That's the fun part!
Here's a good video on how to use GarageBand to create a podcast: http://www.youtube.com/watch?v=8-P8gwvhsr8
- If you are an Apple user, then you already know about GarageBand, which makes creating podcasts very simple.
- GarageBand also included a lot of music stingers and ways you can create music for your podcast.
Skype has a podcasting plug-in (Pamela download) where you can record conversations and then convert to podcasts.
One of the most widely used free services to record voice mail messages and then send that file to your email. You could use this method to create a "live" podcast, including the recorded message/question and then responding to it. You might try this with your students, asking them to call a "Help" line with their questions. Only drawback really is that it is a Seattle area code, so the phone call to access your voice mail would be long-distance if using a land phone line. But who uses those anymore???
Don't forget about this cool tool. (Unfortunately, the version that downloads to your computer and can do this is only available for PC users.) You can send a voicemail to a person on your list, which is sent as an audio attachment. You can also use Google Talk as an Internet radio station: http://labnol.blogspot.com/2007/02/turn-google-talk-into-internet-radio.html
2. Enhanced Podcasts
- Camtasia has a PowerPoint plug in that allows you to
record a PowerPoint and then save it as a podcast. Easy and efficient.
- ProfCast for Apple and SnapKast for PC are other options to create enhanced podcasts.
- GarageBand also enables the creation of "enhanced" podcasts (these can
include images, chapter markers, and/or hyperlinks). GarageBand is
included in the OS X operating system, so there is no extra charge.
3. Video Podcasts
you start realizing that a podcast is simply a converted multimedia
file, you can create a podcast out of just about anything. However, you
should be aware of file size and not create anything too large, since
the download time might be too long.
- You can use
Windows Movie Maker or Apple's iMovie to capture video from a video
camera, edit it, and convert it to H.264. Both of these vide editing
programs are included in the operating systems.
- Camtasia is a screen-capture program that works on PCs to record screen videos and save them for uploading as a
File Conversion Programs
Sometimes you need to convert a file. There are a couple of programs that work quite well:
Be creative and think of the many ways you can used podcasts to enhance learning and engage learners.
(upload your file to this free service, tell it how you want it
oconverted, and then you receive an email when it is done, with a link
to download the converted file. You can convert URL video links this
- Switch Audio File conversion:
This neat little program (free) works on multi-platoforms and will
convert audio files to different formats for you. Again, a real help
when you need it.
- The Zone (ILC128) has audio and video conversion software you can use.
