Reddit mentions of Musimathics: The Mathematical Foundations of Music (Volume 2) (The MIT Press)

Glad to hear it, thank you! And yeah I can think of a few books that really helped me.

For analog, the best book I've read is "A Practical Introduction to Electronic Circuits" (https://www.amazon.com/Practical-Introduction-Electronic-Circuits-ebook/dp/B01MSEO5HX). It's actually a terrible introduction, so the title is dumb, but if you already have a basic knowledge this book will take you to the next level. Also one of the best resources for analog is Dave Jones' YouTube channel EEVBlog (https://www.youtube.com/user/EEVblog). He's an excellent presenter and a real analog pro.

For digital, after you have a good grasp of C, I'd recommend Musimathics Vol. 2 (https://www.amazon.com/Musimathics-Mathematical-Foundations-Music-Press/dp/026251656X/ref=asc_df_026251656X/?tag=hyprod-20&linkCode=df0&hvadid=312152840806&hvpos=1o1&hvnetw=g&hvrand=13200640003814220797&hvpone=&hvptwo=&hvqmt=&hvdev=m&hvdvcmdl=&hvlocint=&hvlocphy=9021581&hvtargid=pla-645450504952&psc=1&tag=&ref=&adgrpid=61316181319&hvpone=&hvptwo=&hvadid=312152840806&hvpos=1o1&hvnetw=g&hvrand=13200640003814220797&hvqmt=&hvdev=m&hvdvcmdl=&hvlocint=&hvlocphy=9021581&hvtargid=pla-645450504952). The first volume can be skipped cause it's mostly acoustics and music theory related, but it's a good book too. The second volume is by far the best explaination of DSP and digital audio synthesis I've come across. If you want something a bit lighter, this is a great book as well (https://www.amazon.com/Audio-Programming-Book-MIT-Press/dp/0262014467/ref=asc_df_0262014467/?tag=hyprod-20&linkCode=df0&hvadid=312140868236&hvpos=1o1&hvnetw=g&hvrand=9994434488221753680&hvpone=&hvptwo=&hvqmt=&hvdev=m&hvdvcmdl=&hvlocint=&hvlocphy=9021581&hvtargid=pla-330509287619&psc=1).
