It was made, the researchers say, on April 9, 1860, on a phonautograph, a machine designed to record sounds visually, not to play them back. But the phonoautograph recording, or phonoautogram, was made playable — converted from squiggles on paper to sound — by scientists at the Lawrence Berkeley National Laboratory in Berkeley, Calif.">Researchers Play Tune Recorded Before Edison </a><br> <a href="http://www.ieee-virtual-museum.org/collection/tech.php?taid=&id=2345805&lid=1" title="The phonoautograph consisted of a cone-shaped speaking horn with a flexible covering on the small end. A sharp point was attached to the flexible diaphragm, and it touched the surface of a piece of paper. The paper was covered with a thin layer of black soot, and if it were moved beneath the stylus as someone shouted down the horn, the resulting vibration of the diaphragm would be captured as a squiggly line in the soot on the paper... The phonautograph could record but not play.">The Phonoautograph </a><br> <a href="http://www.talkingmachine.org/phonautograph.html" title="Leon Scott's ambition was to produce an oral shorthand.
