Product Description
Amazon.co.uk Review
A well-respected textbook in previous versions, this fourth edition of Principles of Digital Audio is a substantial revision of all the chapters, and includes several new sections. From the ground up, this book provides the material you need to master the field of digital audio, with its sophisticated techniques and innovations that have revolutionised both telecommunications and entertainment since it first started to appear.
It starts simply, and builds upon easy concepts in digestible steps towards complexity, dealing along the way with the physics of sound, binary notation and signal processing, and proceeding on to recording, signal error correction, sampling and audio reproduction. It is a repository of basic information about sound and gives a firm grounding in the related mathematics. As an introduction to Digital Audio Tape (DAT) technology, Compact Disk (CD) and DVD, it is second to none, and the source of good historical material as well as brief, lucid technical information.
The earlier editions were famed for excellent diagrams, and this edition won't let you down. Almost any chapter can serve as the launching point for a fascinating journey into new technology presented in such a way that the reader is not daunted by reams of difficult mathematics. The index is very complete and surprisingly helpful, with main discussion topics picked out in bold page numbers. For those wishing to study further there are copious bibliographies to each chapter featuring recent available works. --Wilf Hey --This text refers to an out of print or unavailable edition of this title.
Product Description
The definitive guide to digital engineering--fully updated
Gain a thorough understanding of digital audio tools, techniques, and practices from this completely revised and expanded resource. Written by industry pioneer and Audio Engineering Society Fellow Ken C. Pohlmann, Principles of Digital Audio, Sixth Edition, describes the technologies behind today's audio equipment in a clear, practical style. Covering basic theory to the latest technological advancements, the book explains how to apply digital conversion, processing, compression, storage, streaming, and transmission concepts. New chapters on Blu-ray, speech coding, and low bit-rate coding are also included in this bestselling guide.
- Learn about discrete time sampling, quantization, and signal processing
- Examine details of CD, DVD, and Blu-ray players and discs
- Encode and decode AAC, MP3, MP4, Dolby Digital, and other files
- Prepare content for distribution via the Internet and digital radio and television
- Learn the critical differences between music coding and speech coding
- Design low bit-rate codecs to optimize memory capacity while preserving fidelity
- Develop methodologies to evaluate the sound quality of music and speech files
- Study audio transmission via HDMI, VoIP, Wi-Fi, and Bluetooth

Format:Paperback
An excellent intermediate survey of the digital audio landscape. This text covers conversion, signal processing, channel coding and storage as well as current implementations of the technology. Good illustrations are included for visual reinforcement. Pohlmann's breezy writing style guides the reader from basic physics through dense theoretical discussion to practical examples. A freshman college background in physics and mathematics is useful though not essential.

Format:Paperback
Thoroughly updated 4th edition. As well as definitive and thorough descriptions of the basics of digital audio, DAT, and CD, (and lots, lots, more besides) it now includes new sections on MD, Firewire, USB, and DVD. Useful chapters on perceptual coding and audio for the PC. For good measure, it now includes a good introduction to the issues involved in streaming audio across the Internet. Absolutely essential one-stop solution for musicians, students, and lecturers.

Good reference for electronics engineers
11 April 2006
Format:Paperback|Amazon Verified Purchase
First off, this book is in its fifth edition, and Amazon has lumped together reviews of all editions of this book. So the oldest review shown, written in 1998, is speaking of the 3rd edition, and reviews written prior to 2005 are talking about the 4th edition.
This book is more about the principles of digital audio hardware design than anything. The author, also a college professor, starts with the absolute beginning and the binary number system, sampling, quantization, aliasing, and dither and then moves into all of the topics that you need to design and analyze modern digital audio systems. However, if the information in the first two chapters is news to you, chances are the rest of the book will be over your head. The book is full of flow charts, frequency response diagrams, and detailed block diagrams of actual systems. What it is lacking in is any kind of signal processing mathematics to explain the detailed theory behind what is being covered. There is a chapter entitled "Digital Signal Processing", but it barely introduces and defines the terms. It does show some assembly code for performing some simple filtering tasks, though, but that's the extent of the coverage. If you didn't know DSP before you read this chapter, you certainly won't know it after you read this chapter. The book does a pretty good job of discussing some of the more popular audio standards including MP3. I think this book is best suited for someone with an electronics/electrical engineering background that already knows the theory of digital signal processing and wants to apply that knowledge to the actual design and analysis of digital audio processing systems. Amazon shows the table of contents from the 4th edition, so I show the detailed table of contents for the 5th edition here:

An Excellent Compromize Between Theory And Practice
4 Jan 2000
Format:Paperback
This book is an excellent primer for current technology in digital audio systems. He keeps the obscure mathematics to a minimum, and introduces you to the great amount of technique available in the field today. I found this book, 1st edition, in the library -- and soon after bought the latest edition. An excellent value for the money, and useful to anyone trying to keep up with the digital techniques.
