There are also ways to watermark audio files that can survive the conversion process too as well as quite heavy attempts at removing it.
This is what the movie studios are starting to use on some dvd/bluray and at the cinema, combined with hardware that detects the watermark and disables the audio stream when detected. Idea is, someone pirates a DVD or records a movie at the cinema then try's to play it back on their PS3 it won't work.
Unlike other watermarks it won't be a simple byte comparison to remove either.
