i know nothing of this stuff, but it reminds me of aphex twin and venetian snares encoding images into their sounds. is that a similar thing somehow? i thinknfor venetian snares the track was something like song for my cat. if you'd use certain tools, the frequencies would show a picture of a cat. edit: venetian snares was an album, songs about my cats. you can find it on youtube, unsure if i can link it.
