cool bundle, thanks for posting
with c / c++:
“the audio programming book” from that bundle
“elements of computer music” - f richard moore
“the theory and technique of electronic music” - miller puckette [free online]
these are all classics, covering a lot of ground already.
for a real simple and solid introduction to DSP math, i like “A Digital Signal Processing Primer” by ken stieglitz.
if you want to dig into physical modelling in particular (just a guess) i would start with " Real Sound Synthesis for Interactive Applications" by perry cook, which is also lean and less theory-laden than a JOS book.
i honestly don’t feel like the DAFX book or the pirkle “effects in c++” book add a whole lot to these.
the former is pretty light MATLAB treatments of standard topics; the more advanced ideas that it brings up aren’t treated in enough depth to be super useful IMHO.
the latter is probably great if you “just” want a very cookbookish approach to implementing VST/juce plugins specifically.
i happen to have this one. it’s quite fun, but extremely academic and music-theory oriented. it covers a lot of models that would be useful for making some kind of midi mimicker bot. IMHO relies maybe a little too heavily on the Essen folksong corpus.
i haven’t read the david cope book yet, but based on his other work i imagine that will be a good source of inspiration for more direct creative applications.
