The first recording devices were scientific instruments used to capture and study sound waves. These devices were capable of recording voices and other sounds long before the phonograph. The most famous of these was Leon Scott’s 1857 Phonoautograph. This device used a horn to direct sound toward a flexible diaphragm placed at the small end. Attached to the diaphragm was a stylus and lever assembly that allowed the point to scratch out a line on a rotating cylinder beneath it. The cylinder (glass strips were later used) was coated with “lampblack,” probably applied by holding it over a flame and allowing carbon to accumulate.

A 2001 search for original Phonautograph traces (many are published in facsimile form in books) turned up few from the period before the invention of the phonograph. The device probably lacked the sensitivity to record traces with enough detail to allow modern technology to reproduce intelligible sounds from them. The recordings are also very short – often less than 1 second.
Alexander Graham Bell experimented with a Phonautograph in 1874, shortly before Edison’s invention. Attempting to discover how the ear detected sound, he used a human ear (including the internal parts) from a cadaver, attaching a stylus to the eardrum and using it to make a recording.

Far far away, behind the word mountains, far from the countries Vokalia and Consonantia, there live the blind texts. Separated they live in Bookmarksgrove right at the coast of the Semantics, a large language ocean. A small river named Duden flows by their place and supplies it with the necessary regelialia. It is a paradisematic country, in which roasted parts of sentences fly into your mouth. Even the all-powerful Pointing has no control about the blind texts it is an almost unorthographic life One day however a small line of blind text by the name of Lorem Ipsum decided to leave for the far World of Grammar. The Big Oxmox advised her not to do so, because there were thousands of bad Commas, wild Question Marks and devious Semikoli, but the Little Blind Text didn’t listen. She packed her seven versalia, put her initial into the belt and made herself on the way. When she reached the first hills of the Italic Mountains, she had a last view back on the skyline of her hometown Bookmarksgrove, the headline of Alphabet Village and the subline of her own road, the Line Lane. Pityful a rethoric question ran over her cheek, then
