The MP3 fools the ear by eliminating the least essential parts of a music file…To create MP3 [Karl-Heinz] Brandenberg had to appreciate how the human ear perceives sound. A key assist in this effort came from Suzanne Vega. ‘I was ready to fine-tune my compression algorithm,’ Brandenberg recalls. ‘Somewhere down the corridor a radio was playing “Tom’s Diner.” I was electrified. I knew it would be nearly impossible to compress this warm a cappella voice.’” So Mr. Brandenberg gets a copy of the song, and puts it through the newly created MP3. But instead of the “warm human voice” there are monstrous distortions, as though the Exorcist has somehow gotten into the system, shadowing every phrase.
