There comes a point of no return in every book—a point where you realize your goal isn't to start reading it, but to finish reading it. I think this chapter is that point. You've learned the really difficult stuff—dynamic music in particular—and now you can start rounding out your knowledge with some advanced techniques.
Two of those advanced techniques are addressed in this chapter. Here, you'll learn about DirectX Audio's audio scripting capabilities, and about its real-time effect capabilities.
