We’ve been using Apple’s Podcast Producer to accommodate over 30 course sections per semester in creating a variety of podcasts which integrate into course curricula. Podcast Producer provides an easy-to-use, intuitive interface which allows the choice of screen-casting, video recording, audio recording, or file uploads. The user chooses a type, and begins recording with a click of the button. When finished, they click “publish” and presto, their work is finished.
The files is sent to Podcast Producer (which we currently run on an Xserve) where all of the processing, encoding, and publishing takes place. The podcast can be published to iTunes, blogs, YouTube, or any other file accessible system.
Our course podcasts are mainly published to iTunes U which is integrated with our Blackboard system. The podcasts can then be delivered to only the students enrolled in the class.
For our public productions, Podcast Producer adds bumpers, intros and outros, metadata including cover art, and publishes in multiple formats. Look for more posts in the future on podcasting with Podcast Producer.

iTunes can easily convert audio files that were recorded with portable devices such as iPods or other recorders to podcast formats such as AAC or mp3 (see post on The Difference to learn more about these formats). The following video covers converting files with iTunes and adding information such as titles and artist:
.
Here is a step by step for converting files to AAC or mp3 format:
Convert to AAC (m4a)
- Drag the file to iTunes.
- While the file is highlighted click the Advanced menu at the top.
- Choose Convert Selection to AAC (for MP3 conversion see below)
iTunes makes a duplicate copy of it in the new format. To check the file type (since you now have the original WAV file and an AAC file with the same name, right click your file and choose Get Info. There you will see the file type and be sure you choose the converted one). You can also add information to the track, as well as podcast artwork that you have designed. Drag converted the file out of iTunes to your desktop for easy uploading.
or Convert to MP3
- Follow the directions above using the Advanced menu, but prior to doing so, go to iTunes > Preferences > Advanced > Importing
- There, change the Import Using: AAC to Import Using: MP3 Encoder
- Now when you highlight the track and choose Advanced on the top menu, you will see Convert Selection to MP3 rather than AAC.

There is some confusion over AAC and MP3 audio files. AAC is the newer format (popularized by Apple’s adoption of it in its music store) and has many advantages over the older MP3 format, including higher sound quality and smaller file size. The iTunes Music Store supports both AAC and MP3 formats. If you read up on the two, you will see that AAC is slated to replace MP3 as the most widely used format. (FYI: the MP3 extension ends in .mp3 while the AAC extension ends in .m4a)
If you have an older MP3 media player that doesn’t play AAC files but plays MP3 files, no problem! Read the rest of this entry »

This short 90 second clip covers how to use the Griffin iTalk to record audio on your iPod, which you can later convert to podcast ready formats. Use it to capture lectures, record interviews, discussions, forums, guest speakers, etc.

If you are using Audacity and can’t export your project to the MP3 format, you can export it as a WAV file. WAV files are extremely large. This is fine, but if you want to upload that file to iTunes or Blackboard, you will want it to be smaller and compressed, in either AAC (m4a) or MP3 format. Here’s how you can use iTunes to accomplish this:
Convert to AAC (m4a)
- Drag the file to iTunes.
- While the file is highlighted click the Advanced menu at the top.
- Choose Convert Selection to AAC (for MP3 conversion see below)
iTunes makes a duplicate copy of it in the new format. To check the file type (since you now have the original WAV file and an AAC file with the same name, right click your file and choose Get Info. There you will see the file type and be sure you choose the converted one). You can also add information to the track, as well as podcast artwork that you have designed. Drag converted the file out of iTunes to your desktop for easy uploading.
or Convert to MP3
- Follow the directions above using the Advanced menu, but prior to doing so, go to iTunes > Preferences > Advanced > Importing
- There, change the Import Using: AAC to Import Using: MP3 Encoder
- Now when you highlight the track and choose Advanced on the top menu, you will see Convert Selection to MP3 rather than AAC.
