Producing Great Sound for Digital Video

Amazon.com

Producing Great Sound for Digital Video educates beginning and experienced filmmakers on the intricacies of creating an outstanding soundtrack, from preproduction planning through the final mix.

The entire book is fascinating: it's absolutely packed with useful information and tips. Most of us remember learning in high school physics that sound travels about 1,100 feet per second, but besides gauging the location of a lightning bolt from how long it takes for the thunder to reach our ears, we never found it useful. Imagine, however, shooting a scene from about 90 feet away with a camera-mounted microphone. In this scenario, the audio will lag behind the image by about three frames--not much, but it's certainly noticeable. The problem gets worse as the distance increases. The workaround is to put a microphone next to the subject or slide the audio track so that it syncs with the images.

The book presents other solutions to showstopping problems that, because of lack of experience, a filmmaker wouldn't realize until getting to the editing room. Other critical issues such as preproduction planning, the art of production and recording (including environmental factors and microphone setups), and post-production editing and effects are also discussed.

The advent of low-cost, high-quality video production equipment has ushered in the birth of AV producers and AV presenters who have grand intentions but negligible experience. Digital cameras, inexpensive computers capable of capturing and playing back high-quality digital video, and full-featured editing software offer all kinds of ways to create visual eye candy, but embryonic filmmakers don't always realize that the picture is only half the story. Producing Great Sound for Digital Video explains how the other half works, what to watch out for, and how to achieve professional results. --Mike Caputo

Great Book.......2007-01-19

for anyone that wants to have a professional approach to digital video this is a good book.

If you only buy one book on sound.. This is it.......2006-09-09

Where do I start? In a nutshell, this book *IS* the only book to have on sound if your only buying one. No lie. My background... 20 years ago I used to be the "The Amp Dr" fixing commercial PA systems, amps, etc. I have a much better background on sound than most, I was an electrical engineer after that, designing power supplies, and other analog interfaces to digital equipment. Most of that has been dormant for the last 20 years, but I recently decided to make documentaries, and as two of my first projects deal with music, sound seemed pretty important. I got several books on sound, I figure buy six, one has to be good. You can save your money, this book was the one in six.

Knowing audio but NOT audio for video, one of the most important things I discovered is that a professional quality product (video) can only be made with good sound.. If you think you $2 -$10K pro-sumer camera is going to deliver it with the standard mic turn on "auto level", you're really wrong. Half of good sound is the absence of sound, or at least the absence of unintended sound. Insuring good sound is more work than it sounds, but the quality and impact of what I am shooting now is significantly better than before. Otherwise, its' all like home videos, maybe pretty shots and cleverly edited, but still seems like home videos. It all becomes much clearer after reading this book.

When I picked up this book, it was a mental orgasm. Not only does this guy know his stuff, even more importantly, he knows how to communicate it. The way it was written, I was easily able to skip over the stuff I didn't want to review, and go straight for the meat. It is meaty. Almost EVERYTHING I wanted to know was here. I did end up going back just to see how he explained the basics.. great! One of the things I liked about his style, is some authors will tell you something is bad or wrong, with no explanation.. Jay give you good examples.. the CD recording with the book is worth it's weight in , he give examples of proper recording and bad recording (with explanations). You can actually hear it as oppose to read an explanation and take it on faith. Borrow money if you have too.. but buy it.

My message to Jay:
If you read this Jay, I have a few requests. (1) Don't let this book go out of date. Please do you SNR and distortion measurements on some of the new HD cameras. Given the bit resolution is now even less with HDV (12 bits (HDV) vs 16 bits (DV)), I think dual systems are even more important to cover in greater detail. (2) Update with some of the new digital recorders that are replacing DATs (3) Thanks for a great book!

A rare 'how to' book that delivers actual content!.......2006-01-05

I've often been taken in by large reference books that promise to be a comprehensive guide to a subject, but turn out to be a lot of filler (screen shots of PC applications, or an excuse for the author to give lots of less-than-useful anectodal stories, etc.)

Not so with Jay Rose's 'Producing Great Sound for Digital Video' book. This informative guide covers a lot of ground, including sound theory, equipment explanations and use, and techniques for sound production including NLE tips, audio mixing, mic use etc. The great thing about this book is it is written with the expectation that your sound production values should be professional, but it's still accessible to hobbyists and those on a budget.

While I think novices to the field of sound engineering (like myself) probably benefit most from this work, I think a lot of the material here is useful to the video production community as a whole. I learned a lot from this, great work.

A Top Resource for Anyone who does Serious DV Recording.......2005-04-23

This book is a top shelf resource. It is useful to both novices and those with more experience. Starting with the very basics, and that does involve some physics, it works its way through virtually all aspects of sound production for digital video.

Do not be fooled. You are not going to learn much to improve the built in recording that comes with your camera. The author is unapologetic in his broad condemantion of the built-in stuff in terms of both quality and usablility. He goes into the reasons and gives a bit of advice on making the most of what you have but this is not what the book is about. Instead, it is about exactly what the title claims. Unfortunately, this is seldom if ever achieved with the built in stuff.

After going over some of the basics of sound and recording, different types of equipment are described in terms of suitability to task and cost. After that, the actual use of this equipment is considered in a variety of situations. The book is not just concerned with equipment and its use, however. There are chapters on editing and even on the use of prefessional talent. In short, the assumption is that you want to get good quality audio for your video production. The author then describes how to do exactly that in a variety of settings. Unfortuately, doing the job sometimes takes a bit more effort than just pushing the record button on the camera. It also take a bit more money although it does not have to take a great deal more. It depends on what type of sound is needed and how you are going to use it.

If all you want is to catch the background sound in a home video, spend your money on something else. If you want to learn how to get the best possible sound for your particular need and preserve that sound to use with video, you need this book.

You will understand sound after this book.......2005-03-02

Audio is really important, and this book will make sure you get incredible sound at every shoot. I really recommend this book!

Lots to learn in Auditon 2.......2007-03-09

A great book and cd of data. Because of not the greatest help files and no tutorials that came with Audition 2.0 this program while very powerful can be quite intimidatiing. Classroom in a book is very helpful in getting started and learning how to use the program.

. . . for the cautious.......2007-02-18

Could be considered a waste of time by many who are more experienced with applications of this sort. The difficult part is sticking to the tutorials and not wandering off on your own. Everything covered here can be accessed via the help files and user guide. Adobe might want to consider putting a little more effort into features such as a midi sequencer than reiterating itself.

EXASPERATING BUT INDISPENSIBLE.......2006-09-21

Above all, make sure the version of Audition 2.0 Classroom in a Book IS FOR YOUR OPERATING SYSTEM. Also understand that you must have the program to make sense of the manual.

Classroom in a Book is a good guide, but it has two omissions.

Anyone is in their rights to expect that a guide of this sort would have at least a few passages about live recording---but there is exactly one passing sentence in the entire manual about live recording. In Multitrack View the tracks have a panel wherein (among a great many other virtual dials and buttons and such) there is an "M" button, a "S" button, and an "R" button. "M" is for mute, which is explained more than once (even more than twice over the course of the book). "S" is for "Solo", which is also explained to its death over and over again. But as for the "R" button there is only one sentence regarding it.

"R" is "Armed for Record".

Now, maybe someone with a background in audio-editing software knows full well what "Armed for Record" means. Even for a rank beginner like me it wasn't that hard to figure out, I'll admit, but still for a book to go on and on about the other two buttons and to just mention the third term without any further comment seems to me a fundamental lapse. In my case it made for the beginning of a series of exasperating stumbles.

Going at it blind, I simply clicked on "R" and got a message informing me that the best recording was achieved by switching to ASIO. I knew that ASIO meant "Audio Stream In/Out" and had something to do with the new sound card that I had installed. The old sound card that had originally come with the computer was still in there, but apparently from what the message said I would only get mediocre results if I didn't switch by going to Edit and clicking on Audio Hardware Set-Up and following instructions from there on. Needless to say, this was easily done, and in seconds I had switched the program to my new audio card, which any intermediate or advanced user would have known to do from the get-go. Why install the card and not make sure the program was set to it? Ordinarily I would not even admit to anybody that I had to be told to do this; it's embarrassing; but still Audition is a very involved program; there's a lot to learn; and I was just very new to this whole business.

Anyway, I switched, and that should have been the end of it, but sadly the minute I switched my "R" buttons went gray and became inoperable! What's that? Maybe there's no problem on a Mac; I wouldn't know. All I know is that I'm a Windows XP Home Edition guy as I write this; and I lost my "R" buttons!

To say this upset me and got me mad is an understatement. The next morning I was in a better frame of mind and logically went over the steps and saw that there was a pattern to what was happening. For some reason switching to ASIO will gray out the "R" buttons, but if you close the program and go back to it you'll have your "R" buttons back and still be in ASIO.

It's that simple, but there's no mention of it in the book.

Of course, "Armed for Record" must be followed up by clicking on the circular red button on what is called the "Transport Panel" at the bottom of the screen. You're left to guess this, but anyone who has operated a ghetto blaster or a VCR knows what that red circle is; but still it would nice for Adobe to spell this out for us intimidated newbies.

The other big omission gets back to the same lapse as the other one. The book does not bother to point out that switching to ASIO in Multitrack View will not carry over to Edit View. It may not seem like a big deal, but I freaked out when my stuff sounded so weak in Edit View. I couldn't figure it out. The louder I got it in Edit View the more obnoxiously deafening it became in Multitrack View because the two "views" were coming at me through two entirely different sound cards!

Finally I realized what the problem was. Duh . . .

On the positive side in the last analysis it's actually very nice that the two windows can have different settings to let me know how the same file will sound on different computers. My thing with this will be podcasting, and podcasting is about posting on the Net, so one should be aiming at a happy medium that accommodates ordinary cards and quality cards alike. I'm getting better and better at it. The quality will never be a sound stage level thing, but I'm fast approaching the same smoothness of an FM radio commercial.

So go with this book, yes, but keep my comments in mind as you go.

comprehensive explanation.......2007-02-02

Perkins offers us a deep explanation of how RTP can handle real time audio and, more importantly, video across a standard Internet connection. RTP has now been around for some 10 years, and has been extensively built out, based on practical feedback from its earlier usages.

As you might expect, much of the text concerns the packet formats used in RTP. There are subsidiary protocols within RTP, like its control protocol. Naturally, these are explained, as they are a necessary part of the overall RTP.

Some chapters delve into specific timing issues. One, called lip synchronisation, refers to the difficulty of synchronising the audio and video portions of a video signal. Other chapters discuss how to conceal lost video packets. Error concealment is a very practical necessity in this field.

a must-have book if you are in this area.......2004-12-02

The author is an expert in RTP/RTCP area, and this book is a must-have reference if you are working on this area or interested in . inlcuding VoIP/Videoconferencing, Streaming. The book presents the all technical aspects of RTP/RTCP precisely and correctly.

Excellent material - well presented.......2004-01-17

Colin Perkins is obviously well regarded in the area of RTP with many papers and research to his credit. This book is a very thorough and readable text on RTP. All aspects of RTP are covered in sufficient depth. The only thing that would have improved it would have been access to code. At various sections in the book he refers to an RTP stack that he has written. If this were made available as part of the book it would have been a killer combination.

Of Antiquarian Interest Only!.......2007-10-15

This book is primarily of value if you are connecting antique equipment or trying to resurrect out-of-date gear for which manuals are no longer available. You're not likely to find a "Zener Diode" in anything made in this century and info on phonograph cartridges is only useful to a group of dedicated specialists.

Casual users who want the best out of a modern sound system should see books by Bill Gibson and other authors who discuss CDs and digital audio processing.

Good reference, unbalanced presentation.......2007-01-03

This book is a must-have for anyone serious about audio technology and sound reproduction. Almost all imaginable subjects are covered, making it an excellent reference.
The problem with this book, though, is that it is a collection of articles ("chapters") written by various experts around the world. It appears however that no effort was made by the editor to get spread and depth of content in line. For example, the chapter on transformers is very detailed, with good references at the end, yet the chapter on amplifiers is very weak and gives no references whatsoever.
Also, this book appears to be more written towards the recording community, and covers only a few topics relative to live sound reinforcement. Finally, there is virtually no discussion on sound effects processors.

Simply the Best Book on Audio.......2003-09-21

This is the best book on audio I have seen. It covers a broad range of topics in great depth.

The book goes into great detail about the following areas:
a) human hearing and calculating the acoustic properties of rooms
b) PCB-level electronic components
c) system level components
d) storage media
e) bringing all of the above together into applications

The book assumes the reader has a good foundation in electronics but explains concepts in a very unpretentious way. It's nothing like reading a scholarly journal where you constantly have to look at other articles and review textbooks to understand. If you understand the basics of electronic circuits you will understand this book without consulting other textbooks.

Every audio topic I can think of is explored in this book. If you work on anything related to audio you absolutely should not be without this reference.

The most authorative work I have seen........2003-04-07

I have been playing around with amplifiers and recording equipment for a while now - never had formal education in audio engineering, but I do have some electronic background. This book has helped me a lot in refining my recording techniques, my audio system itself and furthered my understanding of audio systems from microphone placement to cabling, speaker placement, phono cartridge alignment to name but a few. Whatever subject I sought advice on, this book has so far provided me with the answers. I would go as far as saying that whatever this book does not cover is not relevant to audio systems. One word of caution though, this book is not like a "cookbook". You have to have an electronic background in order to make full use of the book - as the title rightly puts it, it is intended for engineers.

Handbook For Sound Engineers.......2002-02-24

You MUST buy this book! Pretend you did not see the price and order this book. It is the most comprehensive book on the subject that I have ever run across. It contains more than 1550 pages of information, diagrams, schematics, and just about anything else you could ever think to need. Covers everything from Accoustic Theory to Zener Diodes (I don't know what they are either...I haven't read that far yet!). I am planning to use this as a refresher for myself (that is what my schooling is in) and for training more sound techs at my church.

great book.......2006-04-12

This book really deserves to be called 'The Ultimate Digital Audio Bible'. It has anything and everything. From basic DSP to video, it's not limited to audio topics. When I read the reviews, I would not hope to read the book from the start, just use it as a reference to explain specific standard highlights. But this book is very readable. I loved it. If you are a computer eng. major who wants to dwell in DSP in any field, this book is great. I don't agree with the prejudice that the book is not very readable. There are sections that are more difficult, but the author explains things in very good analogies and examples. I must mention that I'm a comp. eng. a few months away from MS, so I may not be doing justice to the average reader. But I would never expect to find myself reading through that 700+ book with pleasure. Don't think, buy it. Then try and conceal this secret gem from others.

Good reference for electronics engineers.......2006-04-12

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.

Definitive!.......2006-02-28

Prof. Pohlmann's book has become a firm favourite on my technical bookshelf. I enjoy his easy-going style and commend him for writing an informative and interesting book. I cannot imagine why anyone would not feel the same!

The "bible" of Digital Audio.......2005-09-17

Mr. Pohlmann's book is the most encompassing treatise on Digital Audio that is available today. As an employee at Dolby, I can tell you that you won't find an engineer at Dolby who does not own a copy of Digital Audio. The book can be used in many different ways. Whether you are an expert or a novice, this book will come in handy. I would equate this book to drinking directly from the source of a mountain spring. Don't think about it, just buy it.

Good Reference Book.......2005-08-26

The author does a great job in covering all broad aspects of digital audio. The perceptual coding chapter is specially useful in that the author gives mathematical models that you can implement for your work (equations related to masking, bark conversion, spreading functions, thresholds, etc). My only concer with this book is that too often the information is just simply thrown at you, the reading does not flow well and sometimes its seems like the topics are out of place, or at least, they could have been transitioned more smoothly.

The Book on Advanced Detection Theory.......2003-09-24

As far as I am concerned this is simply the best book for advanced detection theory. Notice the word "advanced", this book is not for the beginner. It is an updated version of Whalen's first edition, which I have kept close at hand for most of my career. Whereas most texts available are weak on the statistical analysis of signals, this book is strong. I would be surprised if anyone who considered himself an expert on detection theory did not have a copy. If it has a weakness it is in showing the direct connections to applications.

An Advanced Book on Detection Theory.......2003-03-26

This is perhaps the best book available for advanced detection theory. The probabalistic underpinnings are discussed at length. A lot of the other reviews complain about the mathematical difficulty of this text; however, it is an advanced text. Not all texts are required to be accessible to beginners in the subject. If you want to become an expert in detection theory, this is the next step after your introductory course(s). To really get there, you need to have experience in the applications as well.

If you don't have some background in detection theory or at least hypothesis testing, then in my estimation this is probably not the book for you. On the other hand if the myriad texts available are beginning to appear to be a little bit weak on the probability/statistics analysis of signals, then this is the book for you.

Worst textbook I ever had.......2002-01-03

This book manages to describe even straight-forward concepts in a way that is simply incomprehensible. If you are learning the material, you often have to read a paragraph many times to make any sense out of it. And let's not blame it on the concepts, what it comes down to is confusing presentation and terrible use of English language.
I can't believe it has second edition.

Good for reference, not for learning.......2000-10-13

This book is adequate for reference, but if you plan on learning anything, this is not the book for you. Typos and the overuse of the same symbols to mean everything create an unfriendly environment for the reader. The book goes into unnecessary derivations and presents the material in a backward order that confuses the reader. In summary: Let H0 be the author's intended message to the reader. Let N be the organization and writing style of the book. Let D0 be the reader's proper interpretation of the author's message. The reader's interpretation is then I = H0+N. Then P(D0|I) <0.25

I would give it zero stars if that was an option.......2000-09-13

This book is written with so much hand-waving that a reader attempting to learn the subject must spend all of their time trying to figure out what the mathematics are that lead to the GOD given answers that Robby N. McDontKnow supplies us with. That last statement may have been a little harsh, but the missing mathematics combined with the frequent typos of the text provide for unequal frustration for any student attempting to learn this topic.

The authors of Voice over IP Fundamentals--three packet-voice specialists at Cisco Systems--initiate their exploration of next-generation technologies for supporting conversations across large distances: the switched telephone network as implemented on large (intercontinental) and small (building and enterprise) scales. They then point out problems with the old way of doing things and illuminate the standards and regulatory conditions that have made Internet telephony attractive. Signaling System 7 (SS7) gets particularly insightful coverage, with ample graphical support for the clear, fact-rich, example-laden prose.

The authors do a great service for readers by breaking packet telephony into its component technologies and explaining each one carefully. Coverage of the various protocols that enable voice over IP, particularly H.323 and Session Initiation Protocol (SIP), is simultaneously clear and deep. The same goes for media gateway protocols and various schemes for translating sounds into digital signals and back again, while retaining maximum clarity. There's even some practical material; concluding chapters diagram Cisco router configurations for voice traffic and flesh out solutions with case studies.

You'll like this book if you need to implement a voice over IP system and know more about IP than you do about traditional voice telecommunications. The patient and detailed explanations of traditional telephony concepts and voice over IP protocols will mesh nicely with your existing data communications knowledge, enabling you to make wise design and product decisions. --David Wall

Covered topics: The Public Switched Telephone Network (PSTN), signaling specifications (including Bell System, ISDN, and Signaling System 7), the basics of Internet Protocol (IP), modulation and compression of voice, Quality of Service (QoS), H.323, Session Initiation Protocol (SIP), and gateway protocols. Business considerations of Internet telephony are also addressed.

Book Description

A systematic approach to understanding the basics of voice over IP

Understand the basics of enterprise and public telephony networking, IP networking, and how voice is transported over IP networks

Learn the various caveats of converging voice and data networks

Examine the basic VoIP signaling protocols (H.323, MGCP/H.248, SIP) and primary legacy voice signaling protocols (ISDN, C7/SS7)

Explore how VoIP can run the same applications as the existing telephony system but in a more cost-efficient and scalable manner

Delve into such VoIP topics as jitter, latency, packet loss, codecs, QoS tools, and security

Voice over IP (VoIP) has become an important factor in network communications, promising lower operational costs, greater flexibility, and a variety of enhanced applications. To help you understand VoIP networks, Voice over IP Fundamentals provides a thorough introduction to the basics of VoIP.

Voice over IP Fundamentals explains how a basic IP telephony infrastructure is built and works today, major concepts concerning voice and data networking, and transmission of voice over data networks. You’ll learn how voice is signaled through legacy telephone networks, how IP signaling protocols are used to interoperate with current telephony systems, and how to ensure good voice quality using quality of service (QoS).

Even though Voice over IP Fundamentals is written for anyone seeking to understand how to use IP to transport voice, its target audience comprises both voice and data networking professionals. In the past, professionals working in voice and data networking did not have to understand each other’s roles. However, in this world of time-division multiplexing (TDM) and IP convergence, it is important to understand how these technologies work together. Voice over IP Fundamentals explains all the details so that voice experts can understand data networking and data experts can understand voice networking.

The second edition of this best-selling book includes new chapters on the importance of billing and mediation in a VoIP network, security, and the common types of threats inherent when packet voice environments, public switched telephone networks (PSTN), and VoIP interoperate. It also explains enterprise and service-provider applications and services.

Covers the Underlying Technology.......2006-11-30

With companies like Vonage beginning to advertise for broad based end user sales on television, VoIP must have become of age. I do notice, however, that Vonage still charges by the minute. I guess they think that this is what customers are used to paying so why not.

This book is aimed not at the Vonage type end user, but at the technically savvy individual. It aimed at three types: people who know circuit switching and want to know more about packet switching, people who know packet switching and want to know more about circuit switching, computer types who know computers but are not expert in communications.

It starts with how the traditional phone system worked and then moves to explain the difference between the old circuit switched system that Ma-Bell developed to the newer packet switched systems of today.

Most of the equipment being discussed is Cisco, as is fitting because it seems that they have just about the most complete line, and because this book is put out by Cisco Press. This is a resonably high level book, it is not intended for the absolute beginner who wants to use VOIP, but at the person who wants to understand the underlying technology. You'll learns lots of new With companies like Vonage beginning to advertise for broad based end user sales on television, VoIP must have become of age. I do notice, however, that Vonage still charges by the minute. I guess they think that this is what customers are used to paying so why not.

This book is aimed not at the Vonage type end user, but at the building of a comprehensive understanding of VoIP and would appeal to the sophisticated home user and to the corporate network engineer charged with moving his company to VoIP. It starts with how the traditional phone system worked and then moves to explain the difference between the old circuit switched system that Ma-Bell developed to the newer packet switched systems of today.

Most of the equipment being discussed is Cisco, as is fitting because it seems that they have just about the most complete line, and because this book is put out by Cisco Press. This is a fairly advanced book. It is not intended for the person who wants to set up a system, but for the person who wants to understand the underlying technology. You'll learn lots of new algorithms.

Good book. Good vendor.......2005-08-09

The book is a very comprehensive introduction to VOIP. It is a very good beginning for anyone with either good networking or good telCo. experience. This book would also be useful for a person with a combination of some net & some telco. It is a technical read, but no so much as to be difficult to get through. A person with no true experience may find themselves a little bit out of their element and should be prepared to do some reference work.

Difficult book to read and understand.......2002-07-24

Although this book is but 15 chapters and 336 pages long it took me an incredible amount of time to read through it due to the complexity with which it was written. I've read several Cisco Press books in the same time it took to read this one! Further, I found myself asking the question over and over again, "If this book is about the fundamentals of Voice over IP and is 'A Systematic Approach to Understanding the Basics of Voice over IP', why is it difficult to grasp even the 'basics' as presented by the authors?" As stated in a previous review, the authors have a great understanding of the topics, however, like my Theory of Operating Systems instructor, they do not do well in 'dumbing' down that information to me, a layperson in this field. This book was definitely written by VoIP engineers for VoIP engineers, not for beginners like myself.

Best suited for Telephony engineers.......2001-06-07

Strong Points: -The people who wrote it are definitely knowledgeable: They have loads of information about almost every topic they discuss -Chapter organization: the chapters are well organized as far as the order in which to expose a reader to the topics, building up to the next. Weak Points: -In almost every chapter, the author(s) frequently mention or compare the topic being discussed with an actual Cisco product. While many people agree they make good products, including myself, this book should be about the VoIP as a standard (as the title implies), not Cisco's products. -The author(s) explain most topics by throwing tons of (or too much) information at the reader, including exceptions to the rule - all in the same sentence. Some of the key points are not even mentioned or elaborated on, while the author goes to point out small or insignificant details. -While discussing the history of Telephony and VoIP technology, the use of acronyms is unavoidable, but the author(s) overuses them to the extreme. At times, there are synonym acronyms that the author(s) will use randomly and interchangeably in the same chart, diagram or sentence; this is highly confusing. Also, there is no glossary, so you have to waste time flipping back through the pages to look up acronyms they spelled out once. Many acronyms are not even defined - they are just mentioned as casual talk to define other acronyms (so have your internet browser ready). -The author(s) frequently define topics and acronyms sections or chapters after they are first mentioned. This is also very confusing and frustrating. -The book is filled with charts and graphs. Most of them you really have to study to understand because they use many little pictures for which there is no legend, and some you flat our need an electrical engineering degree to understand.

Worth Reading, But of Limited Use.......2001-02-27

I've had the Davidson book on the shelf for about a year and finally picked it up for a careful read to help me prepare of Cisco's CVOICE exam. While the book is useful toward that end, I recommend it only cautiously.

No doubt part of the problem is mine; by background includes extensive data but very little voice experience. I found the topic Signaling System 7 and similar topics to be slow reading, and I questioned the value of the IP tutorial. A reader with the inverse of my background may have exactly the opposite experience.

This book is unusually dense with acronyms, even for a technical book. The nature of the topic makes acronyms unavoidable, but I felt the lack of a glossary was a serious deficiency. I frequently found myself flipping back and forth through the book to decode an acronym to no avail. Thorough readers might want to construct their own glossary with index cards.

I also had the sense, especially toward the end of the book, that I was getting less of an explanation of the technology than a simple compendium of features. This was especially evident in those thin sections on the Session Initiation Protocol, the Simple Gateway Control Protocol, the Media Gateway Control Protocol, and the Virtual Switch Controller. I found the sections on the H.323 Protocols and Quality of Service more useful and complete.

There is alot to like here.......2007-05-29

I have collected and used books on sound system engineering for many years and this book has quickly become my favorite. Mine has been borrowed by other engineers so often that I have purchased a second copy. Don and Gene are among the most experienced in the field. They have also both tried to share thier knowledge with others throughout thier careers. This combination of knowledge and desire to share it has produced a book that explains complex ideas in a way that leaves the reader with few questions. It is clear and concise, and is supported by a great number of charts and diagrams. I can't imagine a better way to capture thier knowledge and share it with others. A great number of professionals are going to benefit from this book, and I expect it will be the industry standard for many years to come.

What you need to know and then some........2007-05-15

One of the better books in my collection, and I have many on acoustics and audio from the highly technical to hands-on.

A must acoustic engineering handbook.......2007-05-07

I owned 1st version before and the 3rd revision is a more complete version and gives more information on digital processing aspect.

A Must for the Serious Audio Practicioner.......2007-03-21

Sound System Engineering, 3rd Edition contains a wealth of information on the design, implementation and testing of sound reinforcement systems. Don Davis' section on audio and acoustic measurements is a must read for anyone serious about performing such tasks. The concepts he discusses about signal delay/synchronization and room acoustics will help the reader to understand what is at the very basis of these topics.

Similarly, Eugene Patronis' section on loudspeakers and arrays is not to be missed. It will have you going back again and again to find that piece of information you need about horns, direct radiators, crossovers and arrays. His presentation of signal processing starts with basic sampling and progresses through system theory and digital audio.

Two of the latter chapters on equalization and "putting it all together" are true gems. They yield practical information that you'll be using the next time you're faced with the issues covered.

Sound System Engineering, 3rd Edition takes all of the knowledge contained in the 2nd edition and augments it with up-to-date interface methods and advances in the field of audio and acoustics since its last publication. This text is equally suited for both the novice and the veteran audio practitioner. It is written in such a manner that each time you read a portion of it, something new will come to light.

Best Ever Sound System Design Reference Manual.......2007-03-13

Congratulations to Don Davis and Eugene Patronis, Jr. for writing the most informative book on sound system engineering ever. The book contains all of the elements of theory, design and practical installation. The book is an excellent reference for the sound system engineer.

Sound System Engineering, Third Edition is the most complete technical book on sound system engineering I have ever read. It is a concentrated capsule of knowledge that gives the theory as well as instructions of how to implement the theory. Don has recorded for us how to do the installation process. Dr. Patronis has given us the physics back of the theory and he added the mathematics so one can reporduce the results. There are places that Doc uses the "It is intuitively obvious..." leap of knowledge that some might have trouble working through but it can be done.

Thank you for such a great work

Livingstone's Review.......2000-06-10

A practical book written in a good style to be found useful by both beginners and advanced users. The concepts of practical DSP with focus on applications to communications are well explained.

Book Description

Foreword by Leonardo Chiariglione.
The topic of digital audio coding is of interest to a wide audience, including engineering and industrial professionals working in telecommunications, hardware design, music, and software product development.
Introduction to Digital Audio Coding and Standards provides a detailed introduction to the methods, implementations, and official standards of state-of-the-art audio coding technology. In the book, the theory and implementation of each of the basic coder building blocks is addressed. The building blocks are then fit together into a full coder and the reader is shown how to judge the performance of such a coder. Finally, the authors discuss the features, choices, and performance of the main state-of-the-art coders defined in the ISO/IEC MPEG and HDTV standards and in commercial use today.
The ultimate goal of this book is to present the reader with a solid enough understanding of the major issues in the theory and implementation of perceptual audio coders that they are able to build their own simple audio codec. There is no other source available where a non-professional has access to the true secrets of audio coding.
Introduction to Digital Audio Coding and Standards is based on a graduate course at Stanford University going into its 7th year. The subject material has been fine-tuned through this process to be accessible to readers of vastly differing backgrounds, levels of preparation, and interests. Exercises that apply the concepts covered are included at the end of each chapter.

Only book which consolidates Audio coding & Standards.......2004-06-22

This book describes the basic details and the Signal Processing behind the Audio compression. It also describes PQMF and MDCT in continuation which is rare in books. Almost all the standard audio codecs are described with comparisons. I am delighted to read the book. At least my search end with this book on this topic. After getting this book, I need not look into IEEE & AES papers. For Audio engineers working on this domain should read this book to have a complete picture and overview of the technology and the domain.

Not satisfying for a nerd like myself..........2004-02-24

The book gives a good review of the historical development of audio coding standards with emphasis on ISO. Generally speaking it is well written, but the technical details as well as theoretical aspects are frankly, quite superficial; therefore it is not satisfying for a (proud) nerd like myself. If one's goal is to implement a program to handle the MP3 bitstream, for instance, then the book does not help. If one's goal is to design a new filter bank to improve the MP3 coder, then the book does not help either. However, it is recommended for beginners to get a flavor of the audio coding field.

Touching the core mechanisms underlying digital audio codec........2004-01-18

For a long time in my school life and now as a audio engineer I look forward to this kind of book.
MPEG Audio or AC3 audio standard is rather simple, but the syntax and decoding procedures imply considerably complex algorithms have been included there.
This book explains related theorys - for example filterbanks in detail, psychoacoustics, entropy coding, etc - concretely and expertly. She(Bosi) was one of the leading members in making MPEG Audio Standards.
Strongly recommendable!

First comprehensible book on the topic.......2003-03-14

This is a 'reference' book for anyone interested in how modern perceptual audio coders work. It is very well written, and complete.
