I was doing some filing in iTunes and had to create a new AAC version of an album I had. Currently I have it set to iTunes Plus as I have always done. When the new AAC creation was done, the file size was larger. Can someone explain what's happening? I have included a side-by-side to look at below.
Thx

Hi knarfrh60!
The answer to your question can be found in this article that explains about import settings in iTunes:
iTunes 11 for Mac: Choose import settings
http://support.apple.com/kb/PH12279
Your files that you are comparing have different bitrates. A little more information about bitrates and how they affect file size can be found in this section of that article:
Select the settings available for your encoding format:
Stereo Bit Rate (AAC and MP3 only):The higher the Mono or Stereo kilobits per second (kbps), the higher the audio quality and the larger the file size. The most common bit rate for stereo MP3 files is between 128 kbps and 192 kbps. Lower bit rates are more appropriate for sound files containing voice recordings (as opposed to music).
Thanks for using the Apple Support Communities. Have a good one!

Hi braden85,
Yeah, I knew an original import from a source would have been bigger - but how/why could a file be bigger after creating a new version that's in the library already? I guess I wasn't clear that the origin and destination were the same.... For example, I can't take a low resolution photo and make it hi-def. What's going on here?
What's the difference between iTunes Plus and my previous settings?
