I teach a foundational media technology course at on of the bigger european art universities — I do the same thing with the students using a broadcast wave file.

The goal of the thing isn't to turn them into hackers, it is to give them a feeling what the stuff they work with is made of, what a file is. This is also a great introduction to talk about compression, metadata, encoding, decoding, sample rate, bitdepth and so on.

If you dive that deep into it, the settings in a typical media conversion program will suddenly become much less intimidating. My motto always was: this was made by humans so it should be possible for humans to understand it as well. And this is maybe the "hidden" lesson: If you bring enough patience you can go into the depth of nearly every topic.
