Reddit mentions of A Digital Signal Processing Primer: With Applications to Digital Audio and Computer Music

As far as book recommendations, check out anything by Julius O Smith (his website has all his books for free), A Digital Signal Processing Primer by Ken Steiglitz, The Audio Programming Book by Richard Boulanger & Victor Lazzarini, and this one has been on my wishlist for a while.

The program is very young (under a decade), so I can't give too many examples (our first graduate did land a producer's job at Microsoft, and our second is in R&D upstairs, working on the sound engine for our in-house game engine), but generally these skills translate to other areas of software development that involve heavy DSP knowledge (biomedical tech, watermarking, speech recognition, communications tech).

I should mention DigiPen provides a hyper-focused course of study. It's definitely not a good choice if you're looking for a general education, or even a generalized CS education. Most of what we learn is Assembly/C/C++ in Procedural/Object-Oriented styles. On the upside though, there's a projects course every single term, which is where most of your portfolio comes from.

I know of some good text books that are pretty easy to read. The Oppenheim and Schafer are considered by a lot of my former profs to be the bible of DSP intro:

It's pretty comprehensive, so if you're looking for something simpler, this is a pretty short and intuitive intro text (which was actually my first exposure to DSP!):
