Vertical Cut Recording
The vertical cut recording process is an early method of audio recording by which a stylus cuts a vertical groove into a phonograph record. This is in contrast to the lateral recording system which uses a stylus that cuts side-to-side across a record. The vertical recording process, also known as the hill and dale process, was used to record phonograph cylinder records as well as Edison Disc Records, Pathé disc records, and disc records made by numerous smaller companies. Vertical cut recording was also used as a means of copyright protection by the early Muzak 16-inch background music Background music (British English: piped music) is a mode of musical performance in which the music is not intended to be a primary focus of potential listeners, but its content, character, and volume level are deliberately chosen to affect behav ... discs. In this process the stylus makes a vertical cut, its depth determined in accordance with the current in the recording coil. The groove ...

Audio Recording
Sound recording and reproduction is the electrical, mechanical, electronic, or digital inscription and re-creation of sound waves, such as spoken voice, singing, instrumental music, or sound effects. The two main classes of sound recording technology are analog recording and digital recording. Sound recording is the transcription of invisible vibrations in air onto a storage medium such as a phonograph disc. The process is reversed in sound reproduction, and the variations stored on the medium are transformed back into sound waves. Acoustic analog recording is achieved by a microphone diaphragm that senses changes in atmospheric pressure caused by acoustic sound waves and records them as a mechanical representation of the sound waves on a medium such as a phonograph record (in which a stylus cuts grooves on a record). In magnetic tape recording, the sound waves vibrate the microphone diaphragm and are converted into a varying electric current, which is then converted t ...

Stylus
A stylus (plural styli or styluses) is a writing utensil or a small tool for some other form of marking or shaping, for example, in pottery. It can also be a computer accessory that is used to assist in navigating or providing more precision when using touchscreens. It usually refers to a narrow elongated staff, similar to a modern ballpoint pen. Many styluses are heavily curved to be held more easily. Another widely used writing tool is the stylus used by blind users in conjunction with the slate for punching out the dots in Braille. Etymology The English word ''stylus'' has two plurals: ''styli'' and ''styluses''. The original Latin word was spelled ; the spelling ''stylus'' arose from an erroneous connection with Greek (), 'pillar'.'' Oxford Latin Dictionary'', s.v. "stilus" (2012). The Latin word had several meanings, including "a long, sharply pointed piece of metal; the stem of a plant; a pointed instrument for incising letters; the stylus (as used in literary co ...

Phonograph Record
A phonograph record (also known as a gramophone record, especially in British English), or simply a record, is an analog sound storage medium in the form of a flat disc with an inscribed, modulated spiral groove. The groove usually starts near the periphery and ends near the center of the disc. At first, the discs were commonly made from shellac, with earlier records having a fine abrasive filler mixed in. Starting in the 1940s polyvinyl chloride became common, hence the name vinyl. The phonograph record was the primary medium used for music reproduction throughout the 20th century. It had co-existed with the phonograph cylinder from the late 1880s and had effectively superseded it by around 1912. Records retained the largest market share even when new formats such as the compact cassette were mass-marketed. By the 1980s, digital media, in the form of the compact disc, had gained a larger market share, and the record left the mainstream in 1991. Since the 1990s, records con ...

Phonograph Cylinder
Phonograph cylinders are the earliest commercial medium for recording and reproducing sound. Commonly known simply as "records" in their era of greatest popularity (c. 1896–1916), these hollow cylindrical objects have an audio recording engraved on the outside surface, which can be reproduced when they are played on a mechanical cylinder phonograph. In the 1910s, the competing disc record system triumphed in the marketplace to become the dominant commercial audio medium. Early development In December 1877, Thomas Edison and his team invented the phonograph using a thin sheet of tin foil wrapped around a hand-cranked, grooved metal cylinder. Tin foil was not a practical recording medium for either commercial or artistic purposes, and the crude hand-cranked phonograph was only marketed as a novelty, to little or no profit. Edison moved on to developing a practical incandescent electric light, and the next improvements to sound recording technology were made by others. Fo ...

Edison Disc Records
The Edison Diamond Disc Record is a type of phonograph record marketed by Thomas A. Edison, Inc. on their Edison Record label from 1912 to 1929. They were named Diamond Discs because the matching Edison Disc Phonograph was fitted with a permanent conical diamond stylus for playing them. Diamond Discs were incompatible with lateral-groove disc record players, e.g. the Victor Victrola, the disposable steel needles of which would damage them while extracting hardly any sound. Uniquely, they are just under in () thick. Edison had previously made only phonograph cylinders but decided to add a disc format to the product line because of the increasingly dominant market share of the shellac disc records (later called 78s because of their typical rotational speed in revolutions per minute) made by competitors such as the Victor Talking Machine Company. Victor and most other makers recorded and played sound by a lateral or side-to-side motion of the stylus in the record groove, whil ...

Pathé Records
Pathé Records was an international record company and label and producer of phonographs, based in France, and active from the 1890s through the 1930s. Early years The Pathé record business was founded by brothers Charles and Émile Pathé, then owners of a successful bistro in Paris. In the mid-1890s, they began selling Edison and Columbia phonographs and accompanying cylinder records. Shortly thereafter, the brothers designed and sold their own phonographs. These incorporated elements of other brands. Soon after, they also started marketing pre-recorded cylinder records. By 1896 the Pathé brothers had offices and recording studios not only in Paris, but also in London, Milan, and St. Petersburg. Pathé cylinders and discs In 1894, the Pathé brothers started selling their own phonographs. The earliest Pathé offerings were phonograph cylinders. Pathé manufactured cylinder records until approximately 1914. In addition to standard size cylinder records (), Pathé pro ...

Muzak Holdings
Muzak is an American brand of background music played in retail stores and other public establishments. The name has been in use since 1934, and has been owned by a division or subsidiary of one or another company ever since. In 1981, Westinghouse bought the company and ran it until selling it to the Fields Company of Chicago, publishers of the ''Chicago Sun-Times'', on September 8, 1986. Formerly owned by Muzak Holdings, the brand was purchased in 2011 by Mood Media in a deal worth US$345 million. Muzak was based in various Seattle, Washington locations from 1986 to 1999, after which it moved its headquarters to South Carolina in 2000. The word ''Muzak'' has been a registered trademark since December 21, 1954, of Muzak LLC. In the United States, due in part to the company’s market dominance, ''Muzak'' has come to be used to refer to most forms of background music, regardless of source. It may also be referred to as "elevator music" or "lift music". Though Muzak Hold ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Background Music
Background music (British English: piped music) is a mode of musical performance in which the music is not intended to be a primary focus of potential listeners, but its content, character, and volume level are deliberately chosen to affect behavioral and emotional responses in humans such as concentration, relaxation, distraction, and excitement. Listeners are uniquely subject to background music with no control over its volume and content. The range of responses created are of great variety, and even opposite, depending on numerous factors such as, setting, culture, audience, and even time of day. Background music is commonly played where there is no audience at all, such as empty hallways and restrooms and fitting rooms. It is also used in artificial space, such as music played while on hold during a telephone call, and virtual space, as in the ambient sounds or thematic music in video games. It is typically played at low volumes from multiple small speakers distributing the m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Open University
The Open University (OU) is a British public research university and the largest university in the United Kingdom by number of students. The majority of the OU's undergraduate students are based in the United Kingdom and principally study off-campus; many of its courses (both undergraduate and postgraduate) can also be studied anywhere in the world. There are also a number of full-time postgraduate research students based on the 48- hectare university campus in Milton Keynes, where they use the OU facilities for research, as well as more than 1,000 members of academic and research staff and over 2,500 administrative, operational and support staff. The OU was established in 1969 and was initially based at Alexandra Palace, north London, using the television studios and editing facilities which had been vacated by the BBC. The first students enrolled in January 1971. The university administration is now based at Walton Hall, Milton Keynes, in Buckinghamshire, but has administ ...
