does anyone know of a (free) tool to fingerprint/mark audio-files (mp3) in
an unhearable and (relatively difficult) non-changeable way? It's not the
aim to be able to connect the musical content itself to the fingerprint, but
to uniquely identify an MP3 track without the user hearing the unique-code
inside the MP3 and the user not being able to change this unique code...
