You might want to look for a beginner’s book on audio engineering. I can’t really recommend anything specific since all the books I have on the topic are about ancient technology. 
But I’m sure reading some reviews on Amazon will turn up a number of good selections.
Also Berklee Collage of Music (via Coursera) is offering a free class, Introduction to Music Production, starting July 19. I’ve taken the Berklee/Coursera classes on Songwriting (really lyrics) and Improvisation which were both great and very much exceeded my expectations. I’m certain you’d find a ton of useful info in this class. And check out their other offerings, lots of good stuff - and all of it free.
