The first device that could record actual sounds as they passed through the air (but could not play them back—the purpose was only visual study) was the phonautograph, patented in 1857 by Parisian inventor Édouard-Léon Scott de Martinville. The earliest known recordings of the human voice are phonautograph recordings, called "phonautograms", made in 1857. They consist of sheets of paper with sound-wave-modulated white lines created by a vibrating stylus that cut through a coating of soot as the paper was passed under it. An 1860 phonautogram of Au Clair de la Lune, a title: Music technology (electric) text: study) was the phonautograph, patented in 1857 by Parisian inventor Édouard-Léon Scott de Martinville.

They consist of sheets of paper with sound-wave-modulated white lines created by a vibrating stylus that cut through a coating of soot as the paper was passed under it. The first practical sound recording and reproduction device was the mechanical phonograph cylinder, invented by Thomas Edison in 1877 and patented in 1878. The invention soon spread across the globe and over the next two decades the commercial recording, distribution and title: Phonograph record text: singing and speech made by Scott in 1860 were played back as sound for the first time in 2008. Along with a tuning fork tone and unintelligible snippets recorded as early as 1857, these are the earliest known recordings of sound. In 1877, Thomas Edison invented the phonograph. Unlike the phonautograph, it could both record and reproduce sound. Despite the similarity of name, there is no documentary evidence that Edison's phonograph was based on Scott's phonautograph. Edison first tried recording sound on a wax-impregnated paper tape, with the idea of creating a "telephone repeater" analogous to the telegraph repeater he title: Phonograph text: the original 1877 recording. Wax cylinder recordings made by 19th century media legends such as P. T. Barnum and Shakespearean actor Edwin Booth are amongst the earliest verified recordings by the famous that have survived to the present. Alexander Graham Bell and his two associates took Edison's tinfoil phonograph and modified it considerably to make it reproduce sound from wax instead of tinfoil. They began their work at Bell's Volta Laboratory in Washington, D. C., in 1879, and continued until they were granted basic patents in 1886 for recording in wax. Although Edison had invented the phonograph in 1877 the title: Édouard-Léon Scott de Martinville text: Hayes in 1878. Scott did not visit the US in the 1860s and therefore could not have recorded Lincoln himself, as one version of the legend claims he did. Scott's phonautograms were selected by the Library of Congress as a 2010 addition to the National Recording Registry, which selects recordings annually that are "culturally, historically, or aesthetically significant". Édouard-Léon Scott de Martinville Édouard-Léon Scott de Martinville (25 April 1817 – 26 April 1879) was a French printer and bookseller who lived in Paris. He invented the earliest known sound recording device, the phonautograph, which was patented in France on 25
