pedagogy and mp3

Today's technology now makes this much easier and inexpensive. It is now possible to record from a microphone, a line-in, or from a radio station directly into mp3 files, and click/drag them as needed. All without the assistance of a technician.

So now it is easy to use audio files in the classroom, or in the online portion of a course. Where should this be done?

One obvious place is when an audio (vs. text) area is of interest - e.g. music, animal calls, etc.

Another area has to do with "learning style" preferences. I prefer to read text rather than to listen to text, but I can do either. Some people prefer to listen, and some have a lot of trouble reading, but listening isn't a problem for them. Is this a reason to provide alternatives?

It is easy - but should it be done? If so, where and under what conditions? I've got questions - do you have answers?
