Music Meets Steganography
austad writes "Wired is running a story about how Aphex Twin has encoded a face into one of his songs. The face is visible when viewing the sound through a spectrograph. This is probably something I wouldn't want to see when coding in a dark room at 3AM. Sorry boys and girls, you have to buy the CD if you want to see it, encoding of the song into a lossy format destroys the image."
This is one of the ways musicians can boost sales and get more CD's out: include special features in the encoding. This a) doesnt hurt people who just want the music and/or get screwed over by copy protection, b) doesn't force the consumer to buy anything specific (i.e. hardware, or even the CD in the not-as-legal sense of it) and c) adds something cosmetic, pointless, but nonetheless cool.
I am !amused.
