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.'"

Portability... And security

[KitFox]

People want to take their music everywhere, and get it fast. So they want portability, internet downloads, etc. But the folks with the product want a business model that makes a lot of money, so any way they can enforce anything that complicates copying, porting, or anything else will be on their To Do List.

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?

Just returned my rented steak, fries and salad back to nature. Thank you.

MPEG AAC != Dolby AC-2

[Anonymous Coward]

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).

MP3 vs the rest: Is file size really an issue?

[Simon]

There seems to be an assumption by the technologists and music industry that people are dying for a better format to replace MP3. Better quality, smaller file sizes. I don't believe that is so.

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!

DRM for Everyone! (or am I paranoid?)

[Spellunk]

While the IEEE tries to be impartial on DRM issues, I have seen an increase in DRM on every new storage medium in the last year. I am a member of IEEE and I was so displeased with the DRM of my last MP3 player (the RCA one in the article, actually) that I built one that has no DRM and a better user interface (I'll post it soon)

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.
