process of converting the acoustic energy of sound into some form in which it can be permanently stored and reproduced at any time. In 1855 the inventor Leon Scott constructed a device called a phonautograph that recorded tracings of the vibrations of sound. Thomas Edison, starting about 1877, made great improvements in mechanical sound recording and was the first inventor to achieve the actually audible reproduction of recorded sound. The greatest advances, however, were made after the adoption in 1925 of electromechanical systems using electronic amplifiers (see record player ).
Generally, in recording, the sound waves impinge on a microphone and are converted into an electrical signal that is recorded by a tape recorder. The tape can be edited if desired. When a commercial phonograph record is to be made, a disk of soft acetate composition coated on an aluminum base, called an original, is placed on a rotating turntable. The tape is played back and controls a stylus that cuts a spiral groove starting from the outer edge and moving to the inner edge of the original. For monophonic sound the stylus vibrates from side to side as it cuts the groove. For stereophonic sound the stylus vibrates vertically, as well as from side to side, recording one sound channel in the left wall of the groove and one in the right.
In a series of steps the original is used to make a metal stamper that presses the groove into commercial records. In order to play a commercial record, a stylus...
Although Thomson set up the first electric system, it was Edison who invented the phonograph in eighteen seventy-seven. Editors at Scientific American, who were some of the first to experience Edison's newest creation, were startled. "The machine began by politely inquiring as to our health, asked how we liked the phonograph, informed us that it was very well, and bid us a cordial good night." (RCA Online 2)
At the age of 14, she delivered a child. This child was from another father, so it was killed. The following year she was married to Count Ferencz Nadasdy. He was a very powerful noble in Hungary. Because of his high power, he was often chosen to govern the Hungarian Army during the Ottoman wars. He was not very supportive of her. Only marrying her for her father’s money and power. Making her feel bad about herself. Some people believe that this is why she started to kill and torture the common women, making them feel bad about being a commoner, and her feeling good about being a noble’s daughter.
Before 1925 recordings were made with an acoustical horn that would capture the sound of the musicians in front of it and transferred the vibration to a cutting stylus. No electricity was used. This process was called the acoustical process. In 1925, microphones were introduced to transfer the acoustical energy to an electric signal, which fed the cutting stylus. This electrical process ameliorated recordings sound.
...men who kept them in bondage and to sleep with them?” (6). Almost every night she would have to lie on her back and make love to her husband where she “unleashed [her] fury and [their] moments of love-making resembled a battle” (23) willingly or not. She was stripped of her body and womanly factors, and in her husband's eyes was made to be his sexual slave.

How a record player works is quite simple. A motor is somehow connected to a solid disc so that the disc is rotated at a constant speed. On top of the rotating disc (platter), The record is placed on top, with a slip mat in between. The slip mat can serve two functions. In the past to hold the record in place so that it would not rotate independently of the platter. Now, however, the slip mat serves a much different function. Instead of holding the record in place, the slip mat is now used to reduce the friction between the spinning platter and the record. This way a DJ can scratch (manually move the record, usually at high speeds) the record while the platter continues to spin underneath. Once the record is rotating, a stylus glides along the grooves and picks up the vibrations, these are then converted into audible sound.

Djing is characterized as "the specialty of mixing, scratching, and making music by working with prerecorded (normally records) and making something new." Djing became an integral factor around an indistinguishable time from break dancing. As of now rappers began coming into the photo. As this happened, there turned into a need to deliver a more dull, beat-arranged foundation that individuals could rap over. With the requirement for more beats, DJ Kool Herc was the first to DJ with two turntables. It didn't take yearn for the DJ to end up noticeably a critical factor in the development of Hip-Hop. DJ's are viewed to keep the group celebrating for the duration of the night and on the move floor. The specialty of scratching resembles a marvel. A DJ can snatch any recorded sound and control it to state whatever they need it to state. DJ's brought into play another melodic instrument "the
Thomas Edison has to be credited with starting the recording industry, because without his invention of the phonograph, there might not be music on the radio, or on tapes and CD’s today(Biagi 143). In 1887, a man by the name Emile Berliner replaced Edison’s phonograph with the gramophone and in 1947 Goldmark introduced the LP, or Long-playing record(143-4).
The reign of Queen Elizabeth I is often referred to as "The Golden Age" of English history. Elizabeth was an immensely popular Queen, and her popularity has waned little with the passing of four hundred years. She is still one of the best-loved monarchs, and one of the most admired rulers of all time. She became a legend in her own lifetime, famed for her remarkable abilities and achievements. Yet, about Elizabeth the woman, we know very little. She is an enigma, and was an enigma to her own people.

Edison decided to change the idea by using a tin foil wrapped metal cylinder instead of the paper. The final cylinder phonograph had 2 diaphragm and needle units. One would be for recording date and the other would be for playing it. For the machine to work, one would have to speak into a mouthpiece and the sound vibrations would be imprinted on the cylinder. Then the recording needle would create some sort of groove pattern on the cylinder. The data can then played by back by the data from the created grooves.
The album The Dark Side of the Moon, by Pink Floyd was an album that pushed the boundaries on multi-tracking and tape looping, as well as mixing in1973. The engineer, Alan Parsons, use many unusual techniques to help create the sound that we know and love. Which landed the album on the charts for 750 weeks. Dark side of the moon was first lead engineering job Alan had with Pink Floyd and only took a year to record.

Elizabeth met a different kind of punishment for her actions; instead of a trial being held and the family name facing certain ruin, she was holed up in one of her castles and left to die of old age with only a slight space for food to pass through the door left open to the external world (Alchin).
