As a note, in order to build -some- understanding from their readings, the reader should build on a basis of fundamental knowledge in acoustics and mathematics, otherwise would get lost immediately, since most of the topics are rather specific and hardcore technical to the point that composers, sound designers and studio engineers would hardly need any of this, unless they want to be researchers or DSP implementers. So, before jumping into this, make sure you know about acoustics fundamentals, calculus, trigonometry, complex numbers, Fourier series and transform, sampling and aliasing, etc.
