Long story short, way back when I had ripped a lot of mp3s with various older versions of LAME in various older vbr presets. At some point I messed up the vbr seek data, and ended up using an older vbr-fix to fix them. As a result, tag & rename (for example) shows that these files are supposedly encoded with Xing, eventhough I know they aren't. Vbr fix stripped the lame specific data from them.
Is there a way to re-add some of that LAME specific data in to the header?

Well the problem is that there is no way to know, retroactively, what quality level for instance they were ripped at. The Lame tag info isn't used for anything really at all, while the Xing portion (Lame is just an extended Xing header) contains the important stuff (seeking etc.) I wouldn't worry, but if you're really anal i guess you could write something to easily insert parts of it, or just use a hex editor... you'd basically just be overwriting some 0s in the first (empty) frame with the lame-specific info.
I'm not sure it is possible to even calculate certain fields though.
Here's the spec:

Yeah, it's not really important. More out of curiosity, since a friend pointed out to me that 'why in the world would I use xing to encode mp3s' and then I had to explain to him all that stuff about the seek data etc. What a pain in the ass that was. 
Anyways, I have my collection set up so that the folder name always contains the preset it was ripped with, so in that sense I could easily mass-add that part of the info in there (if application like that existed, that is).
I was also thinking that it could perhaps be possible to check the average bitrate of an album folder, and base some info on that.
I don't have the skill to write a program though, so I guess that average bitrate idea is pointless.

Hi again. I was just looking into hex editing the files, and it's easy enough. Now I'm wondering if there is a hex editor out there that can do mass/batch editing, so I wouldn't have to go through each file individually.
