The '''phonautograph''' is the earliest known device for recording [[w:sound]]. Previously, tracings had been obtained of the sound-producing vibratory motions of [[w:tuning forks]] and other objects by physical contact with them, but not of actual sound waves as they propagated through air or other media. Invented by Frenchman [[W:Édouard-Léon Scott de Martinville]], it was patented on March 25, '''1857'''.<ref name="NPR-Phonautograph"> | |||

Apparently, it did not occur to anyone before the 1870s that the recordings, called '''phonautograms''', contained enough information about the sound that they could, in theory, be '''used to recreate it'''. Because the phonautogram tracing was an insubstantial two-dimensional line, direct physical playback was impossible in any case. Several phonautograms recorded '''before 1861''' were successfully played as sound in '''2008''' by optically scanning them and using a computer to process the scans into digital audio files.
