I think that you can safely use mp3tag's converter tag-filename for this task. no futher tool is required.
Did you have a look at the FAqs? there it is described how to remove part of a string:
/t/967/1
Now, if it is always the same string, you can create an action of the type "Replace" for TITLE.
Enter the string that is always the same and should be removed as search string.
Enter nothing (leave blank) for replace string.
If the string varies, though, it is a different story.
