But researchers say they have unearthed a recording of the human voice, made by a little-known Frenchman, that predates Edisons invention of the phonograph by nearly two decades. The 10-second recording of a singer crooning the folk song Au Clair de la Lune was discovered earlier this month in an archive in Paris by a group of American audio historians. 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 phonautograph recording, or phonautogram, was made playable converted from squiggles on paper to sound by scientists at the Lawrence Berkeley National Laboratory in Berkeley, Calif.
