Greetings!

I know he has the source posted on his site. There was another version I was looking at also. I was trying (unsuccessfully or you would have heard about it) to integrate the VBRfix logic into mp3tool. Right now, mp3tool will not write a Xing header if it is missing. I started on it, but my time is rather limited at the moment.

I am tempted to try and create a bogus header, append it to the front of the file and throw it to mp3tool. Not graceful, but...
