Mix3dmessagez, did you by chance read the first post? I've reconverted ~1400 songs, albums don't necessarily get smaller, some get bigger. For sure it's better, Apple likes to improve its components. Let's move on more technical details/issues.

Yes I have, I was just reporting from my personal findings quicktime itself has been effected by the coreaudio update, and not just the encoder in itunes.

So. Can anybody blind listening any differences between older and current CoreAudio or is the bitrate decrease only result of compression optimization?

I noticed two major differences so far:
  • 3ch(C+L+R) AAC encoding is supported on 7.9.8.1. It already works with qaac without modification on qaac side.
  • ExtAudioFileRead() crashes when decoding HE-AACv2 on 7.9.8.1 (this has nothing to do with qaac, though).

Thanks for the info.

Can Apple (or even qaac) convert to HEv2? Is it possible with a specific command line or it's automatic below certain bitrates?

If it is available, you can probably use "afconvert -d aacp" or something in Mac OS X. I don't have Mac or iOS devices, so I'm not familiar with Apple products at all.
As for qaac, NO (same as iTunes for Windows).

Can a mod please remove the Topic Description so we can keep it general to every iTunes version?

Please delete this post as well.

Thank you.

Apple AAC encoder was already mature since 2005.  I don't think there were any revolutionary changes since then ... and there won't be anymore.

Last change was in April 2013, I don't know if much changes regarding quality, ever since 2006 like you said but I keep track of changes anyway, it doesn't cost me anything reporting here. The audio checksum changes every time there is a number change.

I appreciate the reporting, since I would test a new version if it appears.

Odd, I just downloaded new iTunes. Same version number you mentioned, 11.1.4, but I'm getting a different version of CoreAudioToolbox

I'm getting 7.9.8.5 and the name is still CoreAudioToolbox.dll

iTunes 11.1.4, the file is named "AppleApplicationSupport_CoreAudioToolbox.dll", and the file version/product version for me is 7.9.8.5.
