Ok I have an idea how the SDMI lives thought the wav - mp3 - wav and DA -> AD -> DA. Music is make up of notes. If the note was moved 200MS either way with a known pattern the the music can be water mark and be converted to MP3 back to WAV and still see it. The human ear would not hear it.
What? You must be kidding! 200ms is a HUGE FUCKING amount of time, when making music. 100 ms is even way too much. When syncing my HD recording to my synth and sampler, the latency MUST be < 20ms or else it sounds ilke shit. Just get a MIDI sequencer from the Internet somewhere and try to shuffle the drums or melody around by blocks of 50 ms. I assure you you will be surprised. Apart from that, it is imposible to select single notes from a recording, be it analogue or digital. The first person to be able to deconstruct digital music like that would earn a nobel prize, for that would mean that a critical function of the human brain had been emulated by computers, and that would be a breakthrough for real AI. --Ralph
