[WORLDKINGS] On this day – April 9, 2023 – The 163th Anniversary of the World's First Human Voice Recording (1860)


(Worldkings.org) The earliest surviving recorded sound of the human voice was made on April 9, 1860 when Scott recorded "Au Clair de la Lune" ("By the Light of the Moon") on the device.

Édouard-Léon Scott de Martinville (25 April 1817 – 26 April 1879) was a French printer, bookseller and inventor. He invented the earliest known sound recording device, the phonautograph, which was patented in France on 25 March 1857.

Scott recorded a rhyme on his phonograph on April 9, 1860. However, he did not know how to play them back. Scott's invention never yielded results, and he went back to bookselling. His creation and some of the paper cylinders were sent to museums. More than 160 years later, the voice of Scott can now be heard in what is considered the first-ever recording of human sound.

In 2008, The New York Times reported the playback of a phonautogram recorded on 9 April 1860. The recording was converted from "squiggles on paper" to a playable digital audio file with the IRENE technology, developed by scientists at the Lawrence Berkeley National Laboratory in Berkeley, California. The phonautogram was one of several deposited by Léon Scott in two archives in Paris and only recently brought to light.

The recording, part of the French folk song Au clair de la lune, was initially played at a speed that produced what seemed to be a 10-second recording of the voice of a woman or child singing at an ordinary musical tempo. The researchers leading the project later found that a misunderstanding about an included reference frequency had resulted in a doubling of the correct playback speed, and that it was actually a 20-second recording of a man, probably Scott himself, singing the song very slowly.


It is now the earliest known recording of singing in existence, predating, by 28 years, several 1888 Edison wax cylinder phonograph recordings of a massed chorus performing Handel's oratorio Israel in Egypt.
