I thought it could perhaps 'repair' my rather numerous (~100) files that either provoke 'Illegal format' error or cause a loud burst of noise, both at the very end. They all pass MP3Trim without it detecting anything wrong (all that I tested, that is), and most of them are CBR files bought from MP3.com, so I have nothing to re-rip and encode.
