Book Description

ISBN-10: 0471972266 | ISBN-13: 978-0471972266 | Publication Date: August 1997 | Edition: 1

Well established in the consumer electronics industry, Digital Audio Signal Processing (DASP) techniques are used in audio CD, computer music and DAT components. In addition the applications afforded by this versatile technology now range from real-time signal processing to room simulation. Grounding the theoretical foundations of DASP in terms of practical applications, this book gives meaning to the mathematical concepts behind this subject area. It includes detailed accounts of: AD/DA conversion and DSP systems Digital Transmission Systems and M-PEG audio coding Studio technology and electronic storage media Audio algorithms: equalization, dynamic range control, room simulation and sampling rate conversion For Audio and Communications Engineers this book provides a thorough coverage of the technical basis of DASP. For Research Students in Signal Processing or Applied Physics it transforms erudite audio signal processing theory into tangible concepts.

Editorial Reviews

From the Publisher

At present there is no single source which covers signal processing, audio processing in computer music and advanced analyses of real-time signal processing. Presented in two parts: the first section shows a basis for hardware systems used in digital audio signal processing and the second part discusses algorithms for processing digital audio signals.

5.0 out of 5 stars Concise and Best, November 12, 2004

This review is from: Digital Audio Signal Processing (Hardcover)

This book is the secret weapon during my various audio algorithms development. Hard-to-believe that this less-than-300-pages book has contents over other 1000+ pages books.
For example, Udo use (only) 5 pages to describe psychoacoustic model (with math), but in very detailed treatment. Another example: (Most) other books quotes S/N = (6N+2)dB in PCM, (derived from sine tone model), but Udo also derive the S/N by Gaussian model (real world case), which the result is a lot lower.
It is obvious that Udo really knows everything he is writing about. Must buy!

5.0 out of 5 stars Best book for digital audio signal processing., October 23, 1998

By A Customer

This review is from: Digital Audio Signal Processing (Hardcover)

There are a lot of books claiming to be books for digital audio signal processing. But usually you only get some information about what a CD is. Even if this book also covers some of these basic topics (number representation, A/D converters, digital audio interfaces), most of the book deals with previously unpublished (by books, papers on these topics exist) topics. E.g. it covers noise-shaping, gives you formulas for peaking and shelving filters used in mixing consoles, tells you how to implement a state of the art reverb or dynamic compression algorithm and explains how audio compression using psycoacoustic effects works. The mathematics are not that complicated, but you should already know what FFT or IIR stands for and how they work to be able to use the book.

This review is from: Digital Audio Signal Processing (Hardcover)

This book covers, from more of an electrical engineering perspective, all aspects of digital audio signal processing in both hardware and software. Throughout the book Zolzer makes heavy use of figures and block diagrams, so to understand this book you should probably have an electrical engineering background with a previous course or experience in basic digital signal processing. Zolzer does not stop and take time to explain elementary concepts such as DFT's and Z-transforms. Computer science types might have a hard time understanding this book, since even in the algorithm portion of the book Zolzer makes heavy use of block diagrams and transfer functions to describe the various algorithms. You will not find code in this book. I particularly liked Zolzer's no-nonsense handling of room simulation and psychoacoustics. It was good to see a thorough signal processing perspective on these subjects rather than the non-mathematical recording engineer's viewpoint found in so many books. I highly recommend this book to any engineer familiar with digital signal processing who wants to see how to apply the theory to audio.

Since this book is rather aged, it is hard to find the supplemental material for it anymore. Type the following into a Google command line, complete with quotations: "Interactive Audio Demonstrations" "Digital Audio Signal Processing". If you look at the first link, you will find the supplemental material that includes applets, sets of exercises, and the solutions to all of the MATLAB portions of those exercises, well-commented and in zipped format. This should help the people who are having difficulties understanding the algorithm explanations found in the book.
