Can I use stamp to trim title metadata?

markfilipak

I ripped an audio book to MP3. I used stamp's 'Set Title to File Name' context menu choice to give them distinctive title metadata.

I now have 427 MP3s with title metadata that match the following regular expression:

 /\d\d\d ([^\.]+)\.mp3/

As indicated by the parentheses, I want to save only the middle part. If I wanted to do that with the file names, it would be trivial, but with the (internal) title metadata (?) ... can Stamp do this? How?

Thanks a lot
