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.
Digital Audio Tape (DAT or R-DAT) is a signal recording and playback medium developed by Sony and introduced in 1987. [1] In appearance it is similar to a Compact Cassette, using 3.81 mm / 0.15" (commonly referred to as 4 mm) magnetic tape enclosed in a protective shell, but is roughly half the size at 73 mm × 54 mm × 10.5 mm.
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.)
Although a number of short-lived hybrid studio and consumer technologies appeared in this period (e.g. Digital Audio Tape or DAT, which recorded digital signal samples onto standard magnetic tape), Sony assured the preeminence of its new digital recording system by introducing, together with Philips, the digital compact disc (CD). The compact ...
Thomas Greenway Stockham (December 22, 1933 – January 6, 2004) was an American scientist who developed one of the first practical digital audio recording systems, and pioneered techniques for digital audio recording and processing. He also led the development of the Digital Audio Tape (DAT) system.
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.
In 1953, Emerson Radio and Phonograph purchased Quiet Heet Corp., which entered the company into air conditioning. Although radio represented only 15 percent of Emerson's revenue by 1954, the company credited itself as creating the first clock radio, self-powered radio, and transistorized pocket radio. Production of tape recorders began in 1955.
This modular, digital multitrack device uses tape as the recording medium and could record up to eight tracks simultaneously. It also allowed multiple DA-88 devices to be combined to record 16 or more tracks. [3] The first models in the series (the TASCAM DA-88, DA-38, DA-98 and Sony PCM-800) recorded at 16-bit resolution.
