Title: A book about API, not audio
Review: This book was very disappointing. It is a book about programming audio APIs, not programming audio algorithms. The section on Advanced 3D Techniques is mostly a description of how to use EAX. There is little here that could not be gleaned from the documentation and examples that come with the APIs in question.This has only the barest whisper of theory. Just enough for someone to understand what a certain function in the provided APIs might mean. DSP, FFT and DCT are not even mentioned in the index! In all, this book is pretty much useful only to someone who doesn't want to deal with the included SDK documentation with DirectX Audio. Anyone working upon a different platform, or wishing to go beyond the basics of merely playing back samples should look elsewhere. Do you really need a 640 page long book just to figure out how to play back a sample?
