Édouard-Léon Scott de Martinville ([e.dwaʁ.le.ɔ̃ skɔt də maʁ.tɛ̃.vil]; 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.
An audio format is a medium for sound recording and reproduction.The term is applied to both the physical recording media and the recording formats of the audio content—in computer science it is often limited to the audio file format, but its wider use usually refers to the physical method used to store the data.
The complete Experimental Talking Clock recording. Francois Lambert (13 June 1851 – 1937) was a French American inventor. Lambert is perhaps best known today for making the oldest sound recording reproducible on its own device (1878) on his own version of the phonograph.
Thomas Edison invents the first dictation machine, a slightly improved version of his phonograph. [2] 1936: Invention: A team of engineers at Bell Labs, led by Homer Dudley, begins work on the Voder, the first electronic speech synthesizer. [3] 1939: March 21: Invention: Dudley is granted a patent for the Voder, US patent 2151091 A. [3] 1939 ...
The disc phonograph record was the dominant commercial audio distribution format throughout most of the 20th century, and phonographs became the first example of home audio that people owned and used at their residences. [5] In the 1960s, the use of 8-track cartridges and cassette tapes were introduced as alternatives.
Because the phonautogram tracing was an insubstantial two-dimensional line, direct physical playback was impossible in any case. However, several phonautograms recorded before 1861 were successfully converted and played as sound in 2008 by optically scanning them and using a computer to process the scans into digital audio files.
The digital audio file marked the end of one era in recording and the beginning of another. Digital files effectively eliminated the need to create or use a discrete, purpose-made physical recording medium (a disc, or a reel of tape, etc.) as the primary means of capturing, manufacturing and distributing commercial sound recordings.
The Encyclopedia of Recorded Sound is a reference work that, among other things, describes the history of sound recordings, from November 1877 when Edison developed the first model of a cylinder phonograph, and earlier, in 1857, when Léon Scott de Martinville invented the phonautograph. [1]
