I borrowed this book from my university library and decided to buy at as a result. I have found it invaluable as a reference guide for gaining a general understanding of various techniques. I would recommend it to people who perhaps have a general idea of the subject, and who are looking for something to introduce some of the technical aspects of Sound Recording. However, if you are looking for detailed explanations of anything in particular then this book is probably not the best solution. However, I am very happy with my purchase and often find myself reading it for my own interest rather than as a technical reference. Excellent introduction and reference, but not one for the more experienced professionals.
