Developed by Alesis and first released in 1991, the ADAT machine is capable of recording 8 tracks of digital audio onto a single S-VHS video cassette. The ADAT machine, followed by the Tascam equivalent, the DA-88, using a smaller Hi-8 video cassette, was a common fixture in professional and home studios around the world until approximately ...

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.
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 ...
The groove usually starts near the outside edge and ends near the center of the disc. The stored sound information is made audible by playing the record on a phonograph (or "gramophone", "turntable", or "record player"). Records have been produced in different formats with playing times ranging from a few minutes to around 30 minutes per side.
Since the master was the unique source of the positive, made to produce the stampers, it was considered a library item.
