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 compact disc almost totally dominated the consumer audio market by the end of the 20th century, but within another decade, rapid developments in computing technology saw it rendered virtually redundant in just a few years by the most significant new invention in the history of audio recording — the digital audio file (.wav, .mp3 and other ...
Thomas A. Edison invented the phonograph, the first device for recording and playing back sound, in 1877.After patenting the invention and benefiting from the publicity and acclaim it received, Edison and his laboratory turned their attention to the commercial development of electric lighting, playing no further role in the development of the phonograph for nearly a decade.
A recording made on a sheet of tinfoil at an 1878 demonstration of Edison's phonograph in St. Louis, Missouri, has been played back by optical scanning and digital analysis. A few other early tinfoil recordings are known to survive, including a slightly earlier one that is believed to preserve the voice of U.S. President Rutherford B. Hayes ...
Prior to this point, the earliest known record of a human voice was thought to be an 1877 phonograph recording by Thomas Edison. [ 7 ] [ 14 ] The phonautograph would play a role in the development of the gramophone , whose inventor, Emile Berliner , worked with the phonautograph in the course of developing his own device.
The home phonograph disk recorders of the 1930s were expensive machines that few could afford. Cheaper machines, such as the Wilcox-Gay Recordio line, were sold during the late 1930s through the early 1950s. They operated at 78 rpm only and were similar in appearance to (and not much larger than) a portable phonograph of the era.
Shortly after Thomas Edison invented the phonograph, the first device for recording sound, in 1877, he thought that the main use for the new device would be for recording speech in business settings. (Given the low audio frequency of earliest versions of the phonograph, recording music may not have seemed to be a major application.)
