As with digital editions of many books, the kindle edition of this book is not well formatted. Even worse, the formulae are not correctly transcribed, including inline formulae in the text, making reading it occasionally torturous and tiresome. If you actually need to use any of the equations in this book, you will, undoubtedly, struggle with deciphering an "o" from a lower-case sigma or other such minutia. You may end up guessing and guessing until the formula makes sense. In my opinion, such errors are unacceptable in digital or print at any price, and certainly not at a $70+ text-book price.
Other problems include:
- Organization is sometimes a problem. Different chapters sometimes overlap more than they should, and it's not clear where various things belog, despite spending an inordinate amount of time trying to classify effects in Chapter 1. eg the chapter on virtual analog effects inexplicably covers phasing and wah-wah (which both belong much more naturally in the chapter on filtering), as well as a few misc analog-emulating filters which do belong. You might expect this to be the chapter that covers tube emulation, since that is practically the definition of "virtual analog effects" these days, but that's actually in the non-linear processing chapter. Prepare to bookmark!
- Some of the sections are better than others, and some are relevant to everyday use while others more esoteric -- it's a little unclear to me how they decided to include what. (eg, Why was there no mention of dither except in the glossary? There may well be good reason for this, but it was unclear to me. It also contains a section on analog circuit emulation that explains something called Wave Digital Filter theory. I skimmed this section. It appears to be interesting, but I don't think the book gives enough information for you to put this theory to use without resorting to external references, so it's not clear to me why it's included at all. Again, I only skimmed the section, so I could be wrong.)
- Oddly, I couldn't find any reference whatsoever to the location of the source code online anywhere in the book. Of course it's easy to find ([...]) but this kind of thing is, well, sloppy.
With all that said, I can say I've found a fair bit of useful stuff in the book, and I do this sort of thing for a living, so that should make it clear that there's a ton of good material here, and most of it is explained in very clear language. Some chapters, like the one on automatic mixing, are written in extremely clear, refreshing and intuitive language.
All in all, some of this is an introductory book, some of this is a cookbook of practical code, and some of this is a book on basic theory. It doesn't really know what it wants to be. It's more of a hodge-podge of information about DA-FX than anything else. If you already know the basics, this will extend your knowledge quite nicely. If not, you might still learn a thing or two, but this is probably not the best starting point.
