I find that AAC provides a fuller, richer sound than MP3 overall (particularly on well-known MP3 "trouble spots" like high-hat cymbals or deep bass). In addition, AAC (while still a "lossy" compression like MP3 and therefore inferior to AIFF) provides better fidelity at lower bitrates than MP3, saving space. For example, a 128 AAC is roughly akin to a 192 MP3 ... a savings of about 33% space-wise, with no appreciable loss in fidelity. Over the course of several gigs of music, that can REALLY add up. More importantly from the point of view of Apple and other companies that want to sell songs, AAC has provided for levels of Digital Rights Management (DRM), aka copy protection. Apple has their sets EXTREMELY lightly and the average consumer wouldn't even notice it. Microsoft has taken a more ... "draconian" ... approach so far and looks like they will continue to do so. So, in a nutshell: AAC provides benefits to consumers (better sound, less space) and producers (copyright protection). Honest consumers will not notice the DRM so it's not onerous, determined pirates will find a way around it anyway (but are now subject to prosecution). AAC may never REPLACE the MP3 format, but with lawsuits now being filed against individual music "traders," it's likely to become the format of choice for honest music fans who want to buy music online. > Does iTunes still have the full functions with mp3 and aiff? Yes. > Why won't it just make mp3's out of them if it will makke aiff's? > seems > silly. Not if you've ever heard of "Kazaa" it doesn't. Apple has a strong vested interest in making it difficult for people to rip Apple Music Store tracks and spread them around on the file-"trading" services. And I suppose the reason that unprotected AACs are *also* difficult to make into MP3s is a) there's no reason to make them MP3s if you have an iPod, and b) they're trying to discourage you from choosing MP3 as your format of choice. As for encoding the physical music you already own, you're free to make MP3s out of em if you want to. And there is a way to re-encode AACs as MP3s if you're really desperate. > Is this format going to become a thing to encode one's uploaded music > with? Nope. I don't see the "stolen music" crowd going with AAC much, despite the space savings. It's just not universal enough yet. _Chas_ Claiming that the Macintosh is inferior to Windows because most people use Windows is like saying that all other restaurants are inferior to McDonald's.
