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) For the film, Richard Rodgers added two new songs, "I Have Confidence" and "Something Good", for which he wrote the lyrics as well as the music (Hammerstein having died in August 1960), while three of the original stage songs were omitted,[10] "How Can Love Survive", "No Way To Stop It" and "An Ordinary Couple". Arranger and conductor Irwin Kostal prerecorded the songs with a large orchestra and singers on a stage prior to the start of filming, and later adapted instrumental underscore passages based on the songs. Choreographers Marc Breaux and Dee Dee Wood, who had worked with Andrews on Mary Poppins, worked out all new choreography sequences that incorporated many of the Salzburg locations and settings. The Sound of Music was filmed from March 26 through September 1, 1964, with external scenes shot on location in Salzburg, Austria, and the surrounding region, and interior scenes filmed at the 20th Century Fox studios in California. The movie was photographed in 70Â mm Todd-AO by Ted McCord and produced with DeLuxe Color processing and six-track sound recording.
