[/COLOR]Hi Guys,
You clearly know what you're talking about regarding audio files, so if I may be bold enough to hijack this 2009 thread:
I've pulled music into my iTunes collection from several different sources, such as the iTunes store, CDs, WMA, RealAudio, etc.
On Apple's recommendation, I've optimized the sound quality of all my 7,500 songs by going:
---> iTunes ---> Advanced ---> Create AAC version
I like my iTunes collection to be in VERY neat order.
Therefore, if I find a digital version of a rarity by, for example, The Eagles, I don't just add it to my iTunes collection, and leave it at that.
Instead, I grab ALL my Eagles songs, and convert them ALL to AAC for a SECOND time, in the strict chronological order in which they were originally recorded and/or released, so that when I view my entire iTunes collection via "Date Added," all my Eagles songs are not just together in one block, but in addition, they're simultaneously in strict chronological order.
The problem which I've noticed is that every time I convert what is already an AAC file to being an AAC file for a second, third, fourth, or fifth time, iTunes says that the new file size is regularly larger OR smaller than the previous file size.
Sometimes larger, sometimes smaller, sometimes the same size.
There doesn't seem to be a pattern.
Therefore, three questions:
01. Why do some AAC files get bigger, some get smaller, but others stay the same size ?
02. Every time I "Create AAC version" of a file which is already an "AAC Version" WITHIN iTunes, and then I delete the first AAC file, am I losing anything more than NEGLIGIBLE sound quality in the second AAC file ?
Please say no !
03. In view of the fact that my iTunes collection has 7,500 songs in it, is there a way for me to MINIMIZE the size of an AAC file without losing sound quality ?
Please say yes !
Suggestions about how to decrease the AAC file sizes in bulk would also be very welcome.
I'm running iTunes 10.5.2 (11), within OSX 10.6.8, on a 13" MBP.
Thanks, guys.
Happy new year to my fellow MacHeads.

There we go, an 8.5 mb AAC file has just become an 8.4 mb AAC file.
However, a 17.7 mb AAC file has just grown to 18.2 mb.
What's going on ?
Is the process not the same as simply duplicating a Word document, or a Jpeg photo, both of which always duplicate to exactly the same size ?
Apologies for the multiple postings.
