The Seventh Edition of 'The Sound Studio' may look much the same (in layout and length) as the previous version, but the content is thoroughly updated (with much new digital material) and plainly has been rewritten in detail throughout. The balance between analogue and digital is right on: as the author points out, sound is primarily an analogue medium - at source, microphone, loudspeaker and ear - with some interesting digital possibilities in the processing and recording, which are now introduced and clearly described.
As before, the book provides a broad overview of the whole field for anyone working in radio, recording, film or (like me) television. For professionals in all branches of these media, it will be invaluable for reference - and comes equipped with an unusually good glossary and extensive index. But I would also recommend it as the ideal introduction to the subject for anyone who wants to work in the real, practical world of sound, including sound in support of picture (as distinct from the nerd's private world of digital gimmickry, which so many other audio books in recent years seem to cater for).
The one thing to watch out for when picking up a copy of this book is to make sure it is the up-to-date 7th edition, not the outdated 5th or 6th, of which some are still to be found in libraries and even some shops. AB
