I love reading books on signal processing, especially on audio signal processing. From books on using effects to a so-called reference, I still enjoy reading them, even if they are frustrating. The only one that was is DAFX: Digital Audio Effects, but I haven’t made a review of it!
American universities have some reputation, in all kind of terms, and the amount of student debt is something I also found baffling. So a book on the failure of US universities was obviously of interest to me.
