{#image536}The International Herald Tribune reports on the finding of a 10-second recording of the folk song “Au Clair de la Lune” recorded on April 9, 1860. The recording was made by Édouard-Léon Scott de Martinville on a phonautograph, a machine designed to record sounds visually, but has now been scanned and used for playback. This is now the oldest known sound recording, and can be heard here.
