192 bitrate shows up as 191 bitrate in iTunes

Post by brijazz » Mon May 21, 2007 11:58 am

I'm encoding FLAC to AAC, with the bitrate set to 192 (using CBR, not VBR). However, when I add these files to iTunes, the bitrate on some of them shows up as 191. Why does this happen, and can it be avoided? Not a big deal I suppose, but just curious...

Having the same issues - CBR AAC ends up having a constant bitrate, but it's off by a bit. Using 256kbps, the resulting files have bitrates of 253-255kbps. Using 192kbps, I have a range from 184-192kbps.

Files play fine in iTunes and on my iPod, so it's not a huge issue - but it is rather strange.

Intel Core Duo, 2.0ghz. MacOS 10.4.10, QuickTime 7.1.6, just in case that makes a difference in core audio versions.

A bit old post, but it is still happening. I dont think is releated to the processor since I'm on PowerPC.
