The Experimental Talking Clock was recorded circa 1878 by inventor Frank Lambert. It was long thought to be the world's oldest playable sound recording and is listed in both the Guinness Book of World Records and The Encyclopedia of Recorded Sound as such; however, an older phonautogram recording from 1857 by Édouard-Léon Scott de Martinville was reproduced for the first time in 2008 with the aid of modern technology. It is still the oldest recording that can be played back with its own mechanism, without the involvement of digital technology.
