An Overview Of Present, Future of Music Technology
prostoalex writes "IEEE Spectrum magazine is running a feature article on the state of music and current digital formats. They point to an interesting phenomenon in the digital music world that Steve Jobs emphasized as well: for the first time in music history, the next big format was not about better quality (SACD and such) but about better portability (MP3). 'It was only five years ago that the music industry was facing a civil war over the next-generation disc-based music format -- the successor to the wildly successful CD. At that time, hardly anybody doubted that the music would be encoded optically on a round plastic disc the size of a CD.'"
All the future formats will be about replacing CDDA with "DRM".
Oh, it will be marketed as being about increased audio-fidelity, but it's all about getting rid of those horrible "insecure" CDs.
Belief is the currency of delusion.
Whilst working for a UK Hi-Fi outlet in their engineering department, I have come across a number of players, particularly Sony, which are capable of playing SACD, but I have not noticed any growth in the number of SACD discs available to purchase, it is to all intents and purposes a dead format. MP3 on the other hand is big and getting bigger, in the past four months the number of MP3 players we see passing through our hands has quadroupled. As the article points out, the demand for wifi connections to these devices is also increasing. I fully expect to see the most flexible devices take the lions share of the market, but no doubt the crippled Sony player will have its share of adherents too.

So I end up wondering... With the business they want, and with self-destructing DVD's already a common thing, plus time-limited DRM's, how long until we are reduced to the age of "renting" everything... even that which we purchase fully?
And then, on another front, how long before people start realizing that if people just want to hear the music, Digital-Analog-Digital conversion completely strips DRM... Then how long before some crazy laws come out that make that illegal, and anything that can "Facilitate" such functions illegal... so no computers will have line in anymore, and posession of microphones will result in a still fine and jail term?

Um... Wasn't that the point of cassette tapes? They were a dominant format for a while and the reason they replaced vinyl was their portability and robustness (maybe play-time, too.) Certainly it wasn't about sound quality.
On another note, why does MP3 have to replace CD? For my money, I really don't think that there's any likelihood that'll happen. CDs are simple to use, store enough data, are lossless, and come with pretty packaging. All good things. I can't see why there can't be two parallel distribution systems.
As a technical matter, I just wanted to clarify the error in the article, when the author states: "When people say "AAC" they usually really mean AC-2. Based primarily on adaptive delta modulation technology as refined by Dolby Laboratories, AC-2 was developed for professional audio transmission..." AAC and AC-2 are completely different algorithms. Dolby did develop AC-2 on it's own. Dolby later worked jointly with AT&T/Sony/FhG on developing AAC, which shares some similarities to MP3, but uses improved filterbanks and entropy codes (among other improvements).
Filesize: But when a new computer comes with a 200Gb harddrive do most people these days even care that MP3 maybe isn't the most effective compression algorithm? I mean, you've got plenty for space so who cares if the typical music collection is 5Gb or 10Gb?
Quality: Most people are happy with CD quality. 192Kb MP3 pretty much gives you that quality. Most people are more than happy with MP3, especially on a portable device where listen conditions are 'suboptimal' shall we say.
Portablity vs DRM: This is the killer feature of digital music. The music industry wants to stop it, for everyone else it is all about being able to move music around. This is the one 'feature' that people do not want to see go.
What I've trying to say here is that people are more than happy with MP3 and the 'problems' with MP3 really aren't an issue for the majority of people, while these replacement formats kill the one feature that people really care about.
Good luck marketing your new formats, music industry. You'll need it!

The premise that we can't do without DRM is based on a couple of unfounded assumptions. One is that people will always avoid paying if they can. This has already been proven wrong by the success of iTunes Store (and to a lesser extent competiting offering), despite the fact that there are plenty of sources of free music on the internet (especially P2P software like Kazaa and eMule). The second is that DRM actually works; actually there have been convincing arguments that this will never work, especially considering the fact that a D->A->D conversion will produce very good results (probably as good as 128 bit MP3) and is basically impossible to prevent.
Then consider how much of a turnoff DRM is for customers. I think a good analogy is the early software industry. It used to be that floppy disks were crippled with "copy protection" technology, and a lot of software required the use of a hardware dongle. Nowadays these approaches have gone the way of the dinosaur and software companies tend to rely on much, much lighter weight protection like a simple license code. The reason is that copy protection was more likely to deter well-meaning novice users than hardened hackers, resulting in reduced sales. The software industry eventually realized that the right price points and distribution mechanisms were going to raise their revenues and profits a lot more than these "protections".
To me it seems logical that the music industry will eventually go the same route, even if it means that today's leading players will be dethroned by more forward-looking challengers. They're only clinging to DRM now because they are terrified of cannibalizing their existing revenue streams. This might work for a while but history suggests that they can't hold back the tide of technology forever.
Peer Pressure
Anyways, look out for many of the DRM features lying around to be activated in the near future. The biggest concern will be in memory cards, as most of them have built in features to erase the file after a certain number of plays.
Also in the near future: DVD players having their playing rights revoked (a code on the disc only allows keys stored on approved players to access the content. Both of these are not "coming-up" technologies, they exist at this very moment in hardware, it is just a matter of time before manufacturers activate them.Quidquid latine dictum sit, altum viditur.
Well I THOUGHT the music industry was heading in the right direction with their CD one side DVD other side discs, but I guess I was wrong.
I don't want portability. I'm not going to store 15,000 songs on an MP3 player. Heck, most of them will sit there unused for months. I want quality, DVD quality specifically. The difference between DVD and CD audio is just amazing. People might say there isn't much of a difference between the two, but chances are they're either deaf or have never heard the two compared to each other. It's just sooooo much better than past technologies. The problem is that no companies are putting their music out in DVD format.
Any of you who have audigy 2s, go get your discs and search for your DVD audio sampler disc. You'll have to install creative's junky music player to get it to work(I haven't found a DVD audio plugin for winamp that works with it), but it's worth it to hear the difference. Go on, do it, you can uninstall everything when you're done. You'll be amazed.
WAV isn't compressed format at all (check filesize against audio data rate), IS fully (not virtually) lossless, and although the format wasn't designed for it, being raw audio data, ofcourse you could stream it.
