stivi writes "BusinessWeek has up an article about a war: a standards war in the online music business. Apple's recent deal with EMI to sell DRM-free songs from the publisher's catalog on iTunes may clinch the iPod's AAC format as the industry standard. The article talks about possible reasons why AAC might marginalize WMA, as well as deals with some of the implications of drm-free aac-standardized industry. 'Online music stores, like Napster, Yahoo Music, URGE, and all the others that sell WMA songs will be forced to consider jumping into the DRM-free AAC camp, and thus become iPod compatible, and in so doing become competitors of iTunes. Apple will be fine with this, because in its range of priorities, anything that sells more iPods can only be a good thing. With time, practically all music stores will be selling iPod-compatible songs. This will be considered a Richter 10 event at Microsoft.'"

I disagree. This is likely to change the relative popularity of MP3 and AAC. There are several reasons for this. First, the iTunes store is currently the most popular of the online music services and likely will be the first one taking advantage of this offer. As a result, a lot of MP3 manufacturers are going to be looking to add AAC support to their player to capitalize upon Apple's work and to make transition easy for existing iPod users. This will expand the potential market for AAC files from iPods and Zune, to almost all portable players. With that change, a lot more music services will consider using the AAC format either instead of or in addition to MP3.
Second, right now almost all commercial services require DRM. That means such a service must choose to either use WMA, RealMedia, or roll their own solution. Support for Real is nonexistent among hardware vendors, so they target WMA as the easiest solution. Very few commercial services offer MP3. So how does this event change things? All those WMA offerings are now going to be looking for format for non-DRM'd files that targets the iPod. That rules out WMA. So they are probably going to be choosing AAC or MP3 or both. MP3 is probably a little cheaper for licensing and has wider support, but AAC allows for smaller files for the same level of audio quality, saving bandwidth costs and speeding up downloads. Further, record companies will have already converted masters to sampled AAC for Apple, possibly making that a preference from them.
I don't see that MP3 or AAC will immediately dominate for DRM free music sales, but I bet Apple is not the only major store selling AAC downloads by then end of 2008.

Re:AAC is royalty-free (Score:5, Informative)
AAC is NOT a open standard, unless you consider MP4 to be an "open standard", and it is NOT royalty-free. In fact, I'm pretty sure the licensing for hardware players is slightly more than MP3. This is why most portable audio players don't support AAC, because then they would have to pay double licensing fees (one of MP3, one for AAC) and MP3 is vastly more popular than AAC especially overseas.
Why do they include WMA? Because WMA really doesn't have any licensing fees, and it's as much of an "open standard" as AAC. Microsoft will even write code for your player. Hell, if you're big enough they'll even pay you to include WMA (I know they did for Rio). Nowadays they might be entrenched enough that they've stopped doing this but you can see how they got such momentum.
Apple has no serious interest in promoting AAC as an independent codec. AAC/FairPlay is an important "feature" of iPods and licensing it (Jobs has said outright that they will never license Fairplay) would only cut into their lucrative iPod business. It's the same reason they'll never license MacOS.
Ogg and FLAC aren't widely supported, despite being royalty-free, because of lack of popularity. It just isn't worth it to support these formats. I own one of the very few players that does, the Rio Karma. And yeah, I use FLAC a lot.

That's very misleading. mp3 is MPEG-1 Audio Layer 3, AAC is part of the MPEG-4 specification, .mp4 refers to the container format of the MPEG-4 specification that's based on .mov and can contain a large number of different video, audio and other streams in a number of different codecs.
So an overall better codec. at 128kbs it sounds roughly the same as an 196kbs mp3. Or roughly the same as an OGG at the same bit rate.
This is also misleading, although AAC *is* better. With codecs like these, the only thing that is fixed is the actual bitstream, leaving a lot of leeway to the different encoders. An mp3 encoded with an excellent encoder will be superior to an AAC by a mediocre encoder (e.g. I don't know about Quicktime's aac encodes but its AVC is complete and utter shit, even though AVC is an excellent spec). Also cpu-time constraints can have a serious impact on encoding quality, although that's normally not an issue if you do the encoding on a PC.
One big advantage of AAC are advanced features like 5.1 channels and such. There are hacks to tack on lots of features to mp3 but it lacks the (relatively) clean specs of MPEG-4 and it often lead to all kinds of problems.
the 256kbs mp4 that EMI wants to sell drm free is only good news.
yes, it is. (Good Apple; good EMI too btw, even though it took too long until they saw the light)
MP3's staying power is odd. one can add support for both easily, yet most players seem to think WMA is the only way to go. They could support MP4, MP3, and WMA.
It's not odd. Mp3 is the 800 pound gorilla of music formats and noone can do without it. Apple refused to share its DRM system with anyone (bad Apple), so for most competitors WMA was the easiest way to provide customers the capability to buy music (well, Big-4 music) online, thanks to MS's Played-for-Sure(TM) (until they got the URGE(TM) to squirt(TM) stuff all over the place =) and iirc it's the default spit out by WMP if you tell it to encode something for you. Few non-iPod owners use AAC, so there was no real reason to implement it (similar problem as Vorbis).

AAC is not an Apple-only format. Apple just uses it as the default format for iTunes/iPod. Many mp3 players (both portable and software players) play AAC including the venerable Winamp and it *could* be considered the next-gen mp3 due to it's built-in error correction and more robust features (namely more channels and sampling rates). So I'm not sure how that could "help Apple lock up the hardware market."
While it would be great to have DRM-free OGG files, thereby eliminating licensing fees for players and encoders and bringing costs down across the board. Although I'm not totally sure that would be the best idea since I'm not sure how they match AAC in terms of quality vs filesize and next-gen features.

Because CD-quality songs will overtax today's technology. If you replace the AAC on a typical iPod with a lossless codec you will end up with 1/4 of the song selection and 1/4 of the battery life and if it is a hard disk iPod the hard disk will run all the time and wear out much sooner.
However Apple just announced a trade-in program. You can trade-in your AAC 128 kbit/s plus 30 cents for a 256 kbit/s version of the same song. You lose nothing compared to buying the 256 kbit/s one fresh today. In the future they will obviously upgrade people all the way up to the CD, and then go beyond that.
In music studios it has been common to work at 24-bits for a long time now, and sample rates are up to 192 kHz even in small studios. Since most of the music you bought on CD over the past 10 years is actually a degraded 16-bit copy of the true 24-bit master (it's dithered to lose the extra bits) there is no point in holding up the CD as some sort of ideal. The actual audio content is degraded to fit into your CD player just like audio is degraded in a different way to fit into an iPod.
Even mixing 64 audio channels down to 2 is a way to fit the actual audio content into consumer gear. There are compromises everywhere.

> of digital music?
No, it is not a step backwards. The mistake you're making is that you're defining "audio quality" too narrowly, only looking at specs such as bit depth, sample rate, lossy/lossless encoding, etc. and imagining them in a best case scenario that does not exist in the real world. It is a common mistake. What is always compared is a 16-bit/44.1 kHz raw audio file and a 16-bit/44.1 kHz perceptually encoded audio file, in a music studio or a good listening room, with associated graphs and spectrograms to prove just how much "better" the raw audio file is.
The problem with the above comparison, though, is that no CD's are actually involved, and no CD players. When you put your 16-bit/44.1 kHz audio file onto a CD, right away you have greatly degraded its quality because the bitstream that the CD player sees will not be the same due to the CD's unique and funky volume format and massive error rate. Therefore the CD player will make up the missing bits (so-called error correction) which dramatically degrades audio quality.
What's more, if the CD skips even once during playback you have blown your entire advantage over an iPod. It is gone. The slight improvement in quality that you might have from the CD is gone as soon as it reminds you it is spindles and gears and little whirring parts and lots of 1980's technology. CD's wear out
If you consider other factors like power requirements, you can easily imagine a situation where user A plays their iPod LOUD all day long, enjoying every feature of every song they listen to, while user B is playing their portable CD player at half volume in order to not run out of battery life. The way the human ear works, a loud iPod is better quality audio than a soft CD player no matter what the authoring specs.
Consider a person listening to an iPod with 10,000 songs on it, shuffling away by itself, and they are deeply into the music between their headphones, not having to even lift a finger to change a song or pick a song because it is all playlists, and compare them to another person who is manually shuffling a smaller selection of CD's into and out of a player. Who will perceive the better audio quality during their listening session?
Finally, consider that the iPod did not in fact replace the CD, but rather it replaced the portable and mixable audio cassette. iTunes is two years older than iPod, and iTunes has a CD in

The part that actually matters in this context is that AAC audio is "opener" and "freer" than MP3, which is the previous MPEG perceptual audio encoding standard, and the only other reasonable choice for content producers.
An audio producer can purchase an AAC encoder for say $25 and then use it to encode their work and there are no further fees to pay to the encoder maker and there is no restriction on how the resulting AAC audio files can be sold or used. This is not true with MP3 and certainly not with Windows Media, which both require us to pay a percentage of the sale price of MP3 or WMA files to the encoder maker.
When an audio pro or record company uses MP3 or Windows Media it is like selling a percentage of every song to Fraunhofer or Microsoft.
Windows Media is well known among PC users because Microsoft uses it in their products but it is going nowhere. Microsoft is even less respected in the music industry than they are in the typewriter business where they make all of their profits.

Forth, you're not thinking about this from the music stores' points of view. To them, selling DRM'd music costs a certain DRM'd-format-royalty on a per song downloaded basis. Right now, they mostly pay that royalty to Microsoft since they all use WMV, since Microsoft is the only company licensing a DRM'd format. Selling non-DRM'd music makes them free to choose among non-DRM'd formats, and there are a shit ton of them:
WMV: costs money per song, and is only supported by a small number of clients.
MP3: costs money per song as well but is supported by nearly 100% of clients.
AAC: is free and is supported by 90% of current clients and soon to be 100% of future clients. (Even the Zune supports non-DRM'd AAC, and that's saying something.)
Other formats: no format has wide enough support and small enough bandwidth requirements to even be considered.

It isn't just that AAC has much better audio quality than MP3, which is true. It isn't just that the technology involved is 10 years newer than MP3, which is also true. The main reason that AAC is the standard is that MP3 has a so-called "content tax" and MPEG-4 does not. With MP3 you pay for the encoder, and then you pay again for every file you sell, whether on disc or over the Internet. It is the audio track from a DVD and it is not indie or Internet friendly. It may be a good way to store your CD's on your computer in 1999 but it is not good for replacing the CD for the audio industry. MPEG-4 follows the QuickTime model where you pay only for the encoder and the AAC files you create are your own to do with as you please, similar to CD. This is important not only because the music industry doesn't want to start paying a vig where none existed, but also because there is no system in place to track the vigs, it is not going to happen.
So if you are a content producer and you use AAC instead of MP3, not only does your audio quality improve, but it costs you less money also. It is very, very, very hard to beat an argument that pleases both the music people (higher quality audio) and the business people (keep the vig for yourself).
As for Windows Media
In the music industry, if it doesn't play on an iPod it is not an audio file. PERIOD. The iPod plays all of the standard files plus Microsoft's WAV which is just raw audio, a clone of AIFF. If you take an audio file that plays on the iPod and convert it to something that does not play on the iPod, then you have converted an audio file into a non-audio file. PERIOD. Just because you can burn 10 WMA or Ogg files to a CD-R does not mean you have made an audio CD. Maybe that is impressive in some geek circles but not to music and audio geeks and has no bearing on the music and audio market.
There is nothing at all out there to compete with MPEG-4. The argument that is being made here in this article happened around 2000 or so and it is long over. The fact that it is becoming apparent to people outside the audio industry is the end not the beginning of the process.
