With the numbers I've read, AAC plus should be able to deliver the same audio quality at 48kbps as AAC at 128kbps.
I have to admit, I'm a little skeptical of this. I've been doing some reading too, and my impression has been that 80kbps HE-AAC may be similar quality to 128kbps AAC, and maybe down to 64kbps. Even then I have to wonder. The thing is, most things I've read about it are written to say that HE-AAC "improves the sound quality of low bitrate music" over standard AAC. Not that it comes up to 128kbps quality at low bitrates, but that it just sounds "better" than AAC at those same low bitrates. Interpret however you will.
I've been meaning to do some listening tests for myself, but haven't had time.
But if they upgrade the HD to 5GB, that means 3000 songs instead of 1000. A nice "three times more storage space" is easy to use in marketing. It also upgrades all the current (and older?) iPods capacities by 2.5.
The question is, can the other iPods be updated with AACplus? I have doubts for the 1st and 2nd generation, but what about the 3rd? And most important, will Apple update the firmware of the older iPods (if the iPod can do it).
This will be interesting to see what happens. IF Apple adds HE-AAC support to QuickTime, will they add it to the iPods? On the one hand, it significantly increases the audience for the iPod Mini, as people with larger collections will be more likely to buy it. On the other hand, it could significantly decrease the audience for the larger sized iPods or iPod Photo. Who needs 60 GB when your 10,000 songs will fit on a 20 GB iPod for half the price (assuming you don't want/need the photo features)?
Of course, they did update all iPods to support AAC when the music store came out, so who knows.
Will they "updgrade" the iTMS songs to AACplus? Will they keep using the "old" AAC at 128kbps?
Highly doubtful. Unfortunately my understanding is that they don't have "full quality" versions of any of the music in the store. The record companies encoded the tracks as 128kbps AAC and sent them to Apple. To change this in any way will be a long way off, as it would mean getting every record company to re-encode every song. Huge, huge task.
It would have been nice if they'd structured the deal so that Apple would also get full quality digital copies of every song, so then Apple could re-encode to a better codec or bitrate if they wanted. Even if they had proposed this, I'm guessing the record companies would have balked, seeing it as a way for those pesky customers to get more quality than they deserved!
Edit: just realized that with AACplus, I wouldn't even NEED my 10GB iPod, I'd have more than enough space with a 5GB iPod mini! Dark Blue please
This is why I wish Apple would put out some official word one whether HE-AAC is coming, and whether all iPods will be updated to support it. I understand that announcing the 5 GB Mini now, before the holidays and before they're ready, would kill Christmas sales of 4 GB Minis. But if I knew that my wife's current 10 GB collection would eventually fit on a 4 GB Mini in a month or two, I'd buy her one today. An announcement confirming this future plan would actually increase sales now, as the pressure to buy before December 25 is still on.
As it is, I probably won't buy one, because nothing's guaranteed. Apple's loss, for now. Maybe if the 5 GB Minis ship with HE-AAC by early February, I'll get one as a surprise valentine...
