Hello, guys! I was wondering if there were any books about NES synthesis or something similar to that topic? You know, there are some books about FM synthesis, so maybe it's possible to get the theoretical background about audio capabilities of 2A03 through literature? It is cool to be able to push the limits of the soundchip to create something cool, but if you are not a programmer (just a composer), is it possible to get that knowledge? Was trying to learn NTRQ, but it looks like the lack of the knowledge makes it impossible...
Any help is much appreciated, thank you in advance!
"NES synthesis" doesn't really mean anything. The NES outputs sound using the APU (Audio Processing Unit) located inside the NES's CPU - the 2A03 - which is a PSG (Programmable Sound Generator), not a synthesizer.
With that out of the way, I would be tempted to say that no, I don't think any such NES APU theory book exists, since the 2A03 was very much proprietary to Nintendo; as such, documentation for it was very scarce, and only given out to game developers. Most of what we know about the 2A03 - and indeed other expansion chips used by Famicom games throughout its lifespan - was figured out by various people through reverse-engineering.
That being said, [url=http://wiki.nesdev.com/w/index.php/APU]this would be a good place to start if you want to learn about the NES APU.
