Описание: From smoke captured in April 9th, 1860 manifested as soot pressed on a sheet of paper in a Paris, France laboratory, Édouard-Léon Scott de Martinville (Leon Scott) turned a crank on a contraption he just patented called the Photoautograph autographic stenographer. As the soot covered paper moved forward on a table of the Photoautograph, a bristle from a hog attached to a feather lightly formed what he called a ‘voice calligraphy’ that was etched onto this smoke on paper. The Photoautograph’s sound collection was made from a Tuba he cut to form an “air collector of sound” designed to vibrate a membrane that moved the Hog bristle to create a calligraphy of sound. Scott identified many flaws with this manual hand crank system because it was hard to have a consistent flow of movement. He solved this problem by creating the first “Time-Code” by using a tuning fork of 250hz on one channel as he spoke into another channel with the consistent reference of the 250Hz frequency ever present. Photoautograph was invented nearly 20 years before Thomas Edison experiments with recoding on tin and wax.
