Descripción:
Édouard-Léon Scott de Martinville invents the Phonautograph in Paris. Twenty years before Edison invented the recording process, Frenchman Leon Scott de Martinville invented a device for recording sound. He called it the Phonautograph and patented it on March 25, 1857. It did what it said on the tin and recorded sound, tracing the shape of sound waves as undulations or other deviations in a line traced on smoke-blackened paper or glass. What it didn’t do was play sound back which may be why history is relatively silent about the Phonautograph…….until 2008 when a group of US researchers from the First Sounds Collective digitally converted the phonautograph recording of Au Clair de la Lune that de Martinville made on April 9, 1860 and it is the earliest recognisable record of the human voice and the earliest recognisable record of music.
