QuickTime 7.6.2 is out. Any improvements?
there is also a noticeable increase in encoding speed, at least on my end (average speed when using v. 7.6 was ~25-26x, and and now with 7.6.2 it regularly averages between 28-29x)... would be nice if someone else could verify this, though.
so Snow Leopard is out with Quicktime X (7.6.3) and true vbr AAC has been improved so Q127 uses up to 320 and more bitrates,i tested it and it's really nice (plus XLD uses two cores to encode,much faster). Did anyone test to see how it compares to Nero AAC? New Nero AAC version is in progress so i guess it should be out anytime soon.
VBR Constrained @ 128 kbps is bloody close to transparent now
I don't want to speak for ozmosis but that probably has to do with the settings that iTunes uses. In other words, the VBR constrained setting is used by iTunes and you have to access QuickTime Pro (or XLD) in order to use true VBR encoding. That may all change tomorrow but, right now, only CBR and VBR constrained settings are used by iTunes.
Due to the apparent quality improvements of QuickTime 7.6.3, I wonder if Apple will finally stop using 256kbps VBR as the default ripping/encoding setting in iTunes. I had to help someone today as their 8GB iPod nano was completely filled despite having about 1700 songs on it. They simply downloaded iTunes, installed it, and started ripping their CDs without changing the settings. All of their files were encoded at 256kbps VBR (the iTunes Plus setting). I had the person conduct a few blind ABX tests and it turns out that the iTunes Plus setting is about twice as much as they needed.I thought it was rather "silly" that Apple made that the default ripping/encoding setting in iTunes. This isn't the first time that I have encountered someone like that.
it seems that in regards to at least their music downloads/iTunes, Apple have become more concerned about selling iPods than with offering music with a reasonable quality/filesize
I don't think it's silly. An 8GB Nano was never meant to hold your entire library.And since when do people buy and use only what they need? Do you need 268HP to get to work everyday?
itunes 9 also released. Apparently there's no true vbr AAC but HE AAC,can anyone confirm?
Anyone interested in an AAC listening test?

I can't imagine that there could be any quality gains from boxing in the encoder versus letting it encode as freely as possible, but I was moreso just curious about your choice (or if you were just sharing your results from testing different parameters).
