The Audio Programming Book, edited by Richard Boulanger and Victor Lazzarini, has a brand new Facebook page.
I personally love this book. I spent a lot of time with it when I first received my copy. Within that timeframe, many concepts of what is actually happening behind the scenes of digital audio and synthesis started to become clear to me.
Unfortunately, I got crazy busy, and had to shelf-it. Though I have plans to revisit it this upcoming October.
I did post some of the exercises I was working over at GitHub. If you’re interested:
