Dynaflex (RCA)
Dynaflex is a trademark for a thin, lightweight gramophone record, vinyl LP record, LP phonograph record introduced by RCA Records in late 1969. Rather than using the stiff plastic material used by conventional vinyl pressings, Dynaflex records used a softer, pliable formulation that allowed RCA to use less material, saving money and also making the record appear to lie flatter on turntables. At the time, as a cost-cutting measure, most industry record pressing plants were using recycled or "reground" vinyl, taking old and unsold records, cutting out the center with the paper labels, then melting the rest
down and reusing the material to make new records. Such "reground" vinyl records typically sounded much noisier and scratchier when played than a record made from new or "virgin" vinyl; collectors noted t ...

Dynagroove
Dynagroove is a recording process introduced in 1963 by RCA Victor that, for the first time, used analog computers to modify the audio signal used to produce master discs for LPs. The intent was to boost bass on quiet passages, and reduce the high-frequency tracing burdens (distortion) for the less-compliant, "ball" or spherical-tipped playback cartridges then in use. With boosted bass, tracing demands could be reduced in part by reduced recording levels, sometimes supplemented by peak compression. This added top-end margin permitted selective pre-emphasis of some passages for greater perceived (psychological) brilliance of the recording as a whole. As with any compander, the program material itself changed the response of the Dynagroove electronics that processed it. But, because the changes were multiple (bass, treble, dynamic range) and algorithmic (thresholds, gain curves), RCA justifiably referred to the analog device as a computer. RCA claimed that Dynagroove h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gramophone 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 ...

LP Record
The LP (from "long playing" or "long play") is an analog sound storage medium, a phonograph record format characterized by: a speed of rpm; a 12- or 10-inch (30- or 25-cm) diameter; use of the "microgroove" groove specification; and a vinyl (a copolymer of vinyl chloride acetate) composition disk. Introduced by Columbia in 1948, it was soon adopted as a new standard by the entire record industry. Apart from a few relatively minor refinements and the important later addition of stereophonic sound, it remained the standard format for record albums (during a period in popular music known as the album era) until its gradual replacement from the 1980s to the early 2000s, first by cassettes, then by compact discs, and finally by digital music distribution. Beginning in the late 2000s, the LP has experienced a resurgence in popularity. Format advantages At the time the LP was introduced, nearly all phonograph records for home use were made of an abrasive shellac compound ...

RCA Records
RCA Records is an American record label currently owned by Sony Music Entertainment, a subsidiary of Sony Corporation of America. It is one of Sony Music's four flagship labels, alongside RCA's former long-time rival Columbia Records; also Arista Records, and Epic Records. The label has released multiple genres of music, including pop, classical, rock, hip hop, afrobeat, electronic, R&B, blues, jazz, and country. Its name is derived from the initials of its defunct parent company, the Radio Corporation of America (RCA). RCA Records was fully acquired by Bertelsmann in 1987, making it a part of Bertelsmann Music Group (BMG) and became a part of Sony BMG Music Entertainment after the 2004 merger of BMG and Sony; it was acquired by the latter in 2008, after the dissolution of Sony/BMG and the restructuring of Sony Music. RCA Records is the corporate successor of the Victor Talking Machine Company, founded in 1901, making it the second-oldest record label in American his ...

Audio Storage
Sound recording and reproduction is the electrical, Mechanical system, 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 acoustics, 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, wh ...
