Preface to Second Edition

I have had many gratifying comments about this Pocket Book. It’s good to know that it fills a need, at least for some professionals. The second edition has been very carefully looked at and many alterations and (hopefully) improvements have resulted.

I particularly thank Keith Spencer-Allen for his critical study of the first edition and also for providing most of the material for the section on Digital Audio Tape. I’m also grateful to Vivian Weeks for his major contribution to the section on Audio Measurements.
