I would recommend Spatial Audio to anyone looking to further their knowledge of multichannel recording and mixing techniques. The sections on microphone technique and psychoacoustics are particularly good and more thorough than in a lot of similar books. I wouldn't recommend this book to beginners as the author does assume that the reader already has a reasonable understanding of common sound recording practice. Having said that though, it does contain clear descriptions and is up to date in its coverage of topics such as DVD audio and SACD. Overall I found this book to be interesting to read and not too heavy on formulas and equations. Recommended.
