We’ve written about adding audio and video to your course shell, but this is one of the most comprehensive and useful list of audio recording tips I’ve seen in a while. These suggestions will definitely save you some frustration if you’re considering using audio in an instructor introduction, in unit or content introductions, or elsewhere in your course.
Note that if you follow their tip and use a script, not only will you sound more poised, but you’ll have your transcript (a must for disability accommodations) ready to upload. No need to take the time to transcribe after you make your recording!
As a reminder, the Koehler Center has information about recording and uploading audio clips.
