MP3: The Definitive Guide
The Scoop Judging by the way even my non-technical friends are talking about MP3s, digital music is on a lot of minds. As usual, O'Reilly has published the definitive guide to all things MP3. Computer and music guru Scott Hacker takes you through the codec, the software, the controversies, the competition, and building your own equipment. Though it's aimed at end-users, the book is still accessible to the do-it-yourself weekend hardware wizard.
What's to Like? Hacker's writing is simple and not-too-technical. In places, it's even informal. Sure, there are plenty of gory details, but you won't miss anything essential if you skip over the sidebars now and then. An average computer user could probably create his own MP3s while reading chapter five, for example. Power users aren't left out, though: Audiophiles, hackers and tweakers will benefit from the extensive comparisons of players, encoders, hardware, and competing codecs.
No stranger to alternative operating systems (he also wrote the BeOS Bible), Hacker takes pains to be cross-platform, covering Windows, Mac, Linux, and BeOS. This isn't limited to playback options, though that's the most extensive discussion, but includes serving files over the Internet. Of special consideration are quality issues. The author's perspective as a sound connoisseur comes in handy while discussing optimal (and affordable) recording and playback equipment.
As per the title, the Guide completely covers the subject. If you're interested in collecting MP3s, creating them, playing them back with software, with portable hardware, car hardware, building your own hardware, making music available to others, discovering alternate means of delivery and other codecs, or just want a broad overview of all things MP3, you'll find something of immediate interest. If Hacker whets your appetite for more information, follow one of his references to the source itself. (That's especially nice in his treatment of the more exotic hardware players.)
What's to Consider? Though the chapter on legal information and MP3 is excellent, and among the most extensive treatments of the issue lay readers are likely to encounter, it's U.S. Centric. Also, it should be noted that the digital music debate is undeniably fuzzy, so any interpretations are open to correction. Though he debunks the common disclaimers found on shady MP3 sites, the author wisely sidesteps copyright arguments by explaining the relevant laws, and allowing his readers to come to their own conclusions in the gray areas.People who've been tracking the scene for a while know how fast things change. Information on specific programs or hardware players could become obsolete quickly. (That's noted in the text.) For the most part, Hacker prefers to explain concepts and trends rather than the fine details of any particular implementation. For items still unresolved, such as the eventually supported ID3v2 specification, he provides caveats regarding compatibility issues.
The Summary Catch up to the digital music revolution with MP3: The Definitive Guide. It's packed with information, yet easy to read, and stuffed with links to satisfy your appetite for up-to-the-second information.Purchase this book at ThinkGeek.

There may be more websites with useful information out there. I'm collecting all the MP4 code I can, to see what the specs, in reality, mean. Oh, and to see if there's anything worth filching.Video, I'm not sure. Again, MPEG-4's video layer is said to be very good, but I'd have to see some videos in that format to be convinced. QT4 is OK, but there are no (en|de)coders for it for Linux, which limits it a bit.
It's a small world and it smells funny; I'd buy another if it wasn't for the money; Take back what I paid (SoM)

MP3 is old, too lossy, sounds bad, and has way too many legal messes surrounding it. I'm sure that eventually all of these can be worked around (MP4?), but why bother? Vorbis is here, and is free (speech) and free (beer). Oh, and It's Just Better (tm), too.
</rant>
Remember the SAT? Windows is to Linux as MP3 is to Vorbis.
Doesn't look to bad, but it would be better (in my opinion) if it covered the algorithms used in mp3. They are the most interesting part!
Eh...
You know, people have expressed distaste about the seemingly arbitrary posting policies -without- being immature about it. The ones I saw weren't moderated down.
So, how's puberty going?

10. Annoying the RIAA for fun and profit.
First of all, I'd like to point out that Scot Hacker is the ultamite BeOS evangelist, who also wrote the BeOS Bible and runs the BeTips site.
On a more relevant note, the mp3asm tool availble from the MPG123 web site is a really neat tool to look at the source to - it'll show you the specs of the MP3 format right there. If you're at all interested in the down-and-dirty of dealing with MP3 format files, that source is a great starting point.
I browsed this book last month and found it informative and quite well-written.
The author explains the thorny issues of patents pertaining to MP3. Two corporations have patents on MP3 technologies:
However, as it has been pointed out, the law section is US-centric. It would be interesting to know where in the world the said patents apply. Theoretically, Europe does not allow patents on algorithms and mathematical formulas, but this provision can be circumvented by patenting an overall technique using an algorithm.
Try www.mp3-tech.org or www.mpeg.org for more technical information.

Does this book actually cover algorithms and techniques for encoding MP3s? I know there are algorithms and information on the net, but its one of those areas where how the algorithm is implemented makes all the difference - you really can hear the difference between say BladeEnc and the Fraunhoffer codec.
From the sounds of it, it doesn't which is a pity really as the rest of it is the sort of thing which will become out of date very quickly - the legal situtation is coming to a head and the technology is rapidly advancing. As such, I doubt this will be a huge success with those already familiar with MP3s.

The animal on the cover of MP3: The Definitive Guide is a hermit crab (Coenobita perlatus). The hermit crab is commonly found in the Indian and Pacific Oceans, and inhabits the areas surrounding the Islands of Aldabra, Mauritius, and Samoa.
The MP3 is sometimes found on overseas sites where it can evade prosecution.
Despite the name of the hermit crab, which alludes to a solitary lifestyle, Coenobita perlatus are very social creatures. They characteristically travel in groups of 25 or more, and have been found living in colonies of over 100 in the wild.
MP3s are commonly found in groups of thousands on servers worldwide and typically downloaded in multiple batches.
Hermit crabs make their homes by occupying the discarded shells of gastropds in order to protect their soft, coiled abdomens and inner organs.
MP3s hide by taking the name of Metallica songs to piss of companies who are trying to search for them in order to prosecute downloaders.
