Importing at 128kbps AAC is not working!!!!

I just bought a brand new Mac about a week ago, I also just recieved the update for the new OS (Leopard). Now I am importing CD's into iTunes at 128 kbps AAC and there are bit rates coming up like 127 kbps and 133 kbps. Variable bit rate is unchecked, i redownloaded iTunes after updating my OS and am still expiriencing this problem. Previous to Leopard I never had this issue! HELP!

iMac, Mac OS X (10.5)

I have not yet installed my Leopard upgrade, but this sounds like the way iTunes actually should display the bit rates of the AAC files it encodes. If you play these same files with other software such as foobar2000 on a Windows machine, you'll see minor fluctuations in the bit rate of these files. So, I don't think anything is going wrong with your encoding at all, just that iTunes is interpreting the audio data in a different (yet more accurate) way that it used to.

SINCE UPGRADING TO LEOPARD, I am having the same problem. I import everything at 256 kbps; new imports are displaying in a range between 253 and 260, whereas old imports (before the upgrade) still read 256. Are these importing differently now? Will I eventually have to reimport them in order to get them to conform to the old standards?

I can't imagine why this behavior would have changed with the upgrade, but who knows.

You don't seem to be grasping the point that no one has ever managed to have a truly constant bit rate of 128 kbps with any AAC files encoded with iTunes, regardless of what iTunes displays as the bit rate. I'm not here to argue with you, so good luck with your troubleshooting.

If the Smart Playlist functionality is broken as a result of this change (I can't test this until at least tomorrow when Leopard arrives in the mail), then by all means you should submit feedback to Apple following the link below.

Hopefully Apple will be able to tweak things a bit so that encoder settings can still be used as a Smart Playlist criterion even if the displayed bit rate is other than that specified by the user.

Thank you for taking the time to confirm this behavior. Hopefully others will submit feedback to Apple as well, as something definitely appears to have been broken as far as the ability to create Smart Playlists based on bit rate (at least without specifying a range of who knows how many kbps).

P.S. A link to this discussion thread in the submitted feedback would save a lot of typing and explanation.
