when was sound captured for the first time
Sound recording and reproduction 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.[6] 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 French folk song, was played back as sound for the first time in 2008 by scanning it and using software to convert the undulating line, which graphically encoded the sound, into a corresponding digital audio file.[6][7]
The Sound of Music (film) Later that night at the festival, during their final number, the von Trapp family slip away and seek shelter at the nearby abbey, where Mother Abbess hides them in the cemetery crypt. Brownshirts soon arrive and search the abbey, but the family is able to escape using the caretaker's car. When the soldiers attempt to pursue, they discover their cars will not start as two nuns have removed parts of the engines. The next morning, after driving to the Swiss border, the von Trapp family make their way on foot across the frontier into Switzerland to safety and freedom.
