iPod/iTunes support

220.253.77.88 21:32, 13 May 2007 (UTC)"As of 2007, neither iTunes, nor iPod does support HE-AAC. Only MPEG 2 AAC (MPEG 2 Audio - part 3) is supported so the only players for Mac OS X are VLC (without metadata/title streaming) and Songbird."[reply]

Is this statement specific to streaming, because iPod supports MPEG-4 AAC?

Sort of. Don't confuse the MPEG-4 container format (denoted by filename extension) with the MPEG-4 High Efficiency extensions to MPEG-2's Low Complexity AAC. As I understand it, currently, no AAC streaming whatsoever is supported by iTunes. Playback of static LC-AAC files is possible, but I don't know if the LC-AAC data has to be in an MPEG-4 container or if raw .aac will play as well. According to the iTunes article, HE-AAC static files are playable but they're decoded at 22 kHz, thus cutting off the high end (and making the rest sound slightly fuzzier). I don't know if iPod's capabilities match those of iTunes. —mjb 21:51, 13 May 2007 (UTC)[reply]

MPEG-2 Part ????

The article talks abut AAC being part of MPEG-2 Part 3, but the AAC article says it is MPEG-2 part 7 and MPEG-4 part 3. So is the HE-AAC article incorrect or is the AAC article? (or is there some other reason that perhaps could use some explanation?)--Jccalhoun 16:59, 17 May 2007 (UTC)[reply]

Dolby turns HE-AAC v2 into Dolby Pulse

It seems as if, now that Dolby has acquired Coding Technologies, they've created a new Dolby product, Dolby Pulse, that is more or less just HE-AAC v2 with 'Dolby metadata'. Obviously, this will need to be mentioned, but my question is:

Do we mention Dolby Pulse as a part of HE-AAC v2, or do we move all the article's contents to Dolby Pulse with relevant additional information?

I would have also suggested creating two seperate articles but the overlap between the two articles would not have justified that decision.
