Stereophonic sound, commonly called stereo, is the reproduction of sound using two or more independent audio Sound recording and reproduction is an electrical or mechanical 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. Acoustic analog recording is achieved by a small microphone diaphragm that channels through a symmetrical Symmetry generally conveys two primary meanings. The first is an imprecise sense of harmonious or aesthetically pleasing proportionality and balance; such that it reflects beauty or perfection. The second meaning is a precise and well-defined concept of balance or "patterned self-similarity" that can be demonstrated or proved according configuration of loudspeakers A loudspeaker is an electroacoustic transducer that converts an electrical signal into sound. The speaker pulses in accordance with the variations of an electrical signal and causes sound waves to propagate through a medium such as air or water in such a way as to create the impression of sound heard from various directions, as in natural hearing. It is often contrasted with monophonic Monaural or monophonic sound reproduction is single-channel. Typically there is only one microphone, one loudspeaker, or (in the case of headphones and multiple loudspeakers) channels are fed from a common signal path. In the case of multiple microphones the paths are mixed into a single signal path at some stage, or "mono" sound, where audio is in the form of one channel, often centered in the sound field (analogous Analogy is a cognitive process of transferring information from a particular subject to another particular subject (the target), and a linguistic expression corresponding to such a process. In a narrower sense, analogy is an inference or an argument from one particular to another particular, as opposed to deduction, induction, and abduction, where to a visual field The term visual field is sometimes used as a synonym to field of view, though they do not designate the same thing. The visual field is the "spatial array of visual sensations available to observation in introspectionist psychological experiments", while 'field of view' "refers to the physical objects and light sources in the).
Stereo recordings are used in FM broadcasting FM broadcasting is a broadcast technology invented by Edwin Howard Armstrong that uses frequency modulation to provide high-fidelity sound over broadcast radio and Digital Audio Broadcasting Digital Audio Broadcasting , is a digital radio technology for broadcasting radio stations, used in several countries, particularly in Europe. As of 2006, approximately 1,000 stations worldwide broadcast in the DAB format (DAB) and in several television systems. To record in stereo, sound engineers use various methods, including using two directional microphones A microphone, colloquially called a mic or mike , is an acoustic-to-electric transducer or sensor that converts sound into an electrical signal. In 1876, Emile Berliner invented the first microphone used as a telephone voice transmitter. Microphones are used in many applications such as telephones, tape recorders, karaoke systems, hearing aids,, two parallel omnidirectional microphones, or more complex techniques. Several monophonic records, such as the original Broadway cast recordings of Oklahoma! Oklahoma! is the first musical written by composer Richard Rodgers and librettist Oscar Hammerstein II. The musical is based on Lynn Riggs' 1931 play, Green Grow the Lilacs. Set in Oklahoma Territory outside the town of Claremore in 1906, it tells the story of cowboy Curly McLain and his romance with farm girl Laurey Williams. A secondary romance (1943), Carousel Carousel is a musical by Richard Rodgers and Oscar Hammerstein II (book and lyrics) that was adapted from Ferenc Molnar's 1909 play Liliom, transplanting the Budapest setting of Molnar's play to a New England fishing village. The show includes the hit musical numbers If I Loved You, June Is Bustin' Out All Over, and You'll Never Walk Alone (1945), and South Pacific South Pacific is a 1949 musical with music by Richard Rodgers, lyrics by Oscar Hammerstein II and book by Hammerstein and Joshua Logan. The story draws from James A. Michener's Pulitzer Prize-winning, 1948 novel, Tales of the South Pacific, weaving together characters and elements from several of its stories into a single plotline. The musical won (1949), were once reissued in "fake" stereo to create the impression that the sound was originally recorded in that medium.
The first stereo transmission was made telephonically by Clément Ader in 1881. The BBC The British Broadcasting Corporation, usually referred to by its abbreviation as the "BBC", is the longest established and largest broadcaster in the world. The BBC is funded by an annual television licence fee, which is charged to all United Kingdom households using equipment capable of recording and/or receiving live television made radio's first stereo broadcast in December 1925. In the 1930s, Alan Blumlein Alan Dower Blumlein was an English electronics engineer, notable for his many inventions in telecommunications, sound recording, stereo, television and radar. He received 128 patents and was considered as one of the most significant engineers and inventors of his time of EMI The EMI Group is a British music company. It is the fourth-largest business group and family of record labels in the recording industry, making it one of the "big four" record companies. EMI Group also has a major publishing arm - EMI Music Publishing - based in New York City. The company was once a constituent of the FTSE 100 Index but patented stereo records, stereo films, and also surround sound.[1] Harvey Fletcher Harvey Fletcher was an American physicist. He is credited with the invention of the hearing aid and the audiometer. He is remembered as a trail-blazing investigator into the nature of speech and hearing, and for his numerous contributions in acoustics, electrical engineering, speech, medicine, music, atomic physics, sound pictures, and education of Bell Laboratories Bell Laboratories is the research and development organization of Alcatel-Lucent and previously of the American Telephone & Telegraph Company (AT&T) investigated techniques for stereophonic recording and reproduction. The first commercial motion picture to be exhibited with stereophonic sound was Walt Disney Walter Elias "Walt" Disney was an American film producer, director, screenwriter, voice actor, animator, entrepreneur, entertainer, international icon and philanthropist. Disney is famous for his influence in the field of entertainment during the twentieth century. As the co-founder (with his brother Roy O. Disney) of Walt Disney's Fantasia Fantasia is a 1940 American animated feature produced by Walt Disney and the third film in the Walt Disney Animated Classics series. Fantasia features animation set to classical music and no dialogue—only spoken introductions by the host, American composer and music critic Deems Taylor, before segments. The music was recorded under the direction (1940). By the mid-1950s, multichannel sound was common for big-budget Hollywood motion pictures.[2] In 1953, Remington Records Remington Records was a low budget record label. It existed from 1950 until 1957 and specialized in classical music and jazz. Unfortunately, the discs suffered from considerable surface noise began taping some of its sessions in stereo, with the first stereophonic phonograph discs available to the general public in 1958.

The FCC works towards six goals in the areas of broadband, competition, announced stereophonic FM In telecommunications, frequency modulation conveys information over a carrier wave by varying its frequency (contrast this with amplitude modulation, in which the amplitude of the carrier is varied while its frequency remains constant). In analog applications, the instantaneous frequency of the carrier is directly proportional to the technical standards in April 1961, and licensed regular stereophonic FM radio broadcasting, to commence that same year. In 1984, multichannel television sound was adopted by the FCC The Federal Communications Commission is an independent agency of the United States government, created, directed, and empowered by Congressional statute (see 47 U.S.C. § 151 and 47 U.S.C. § 154), and with the majority of its commissioners appointed by the current President.

A standard is a document that establishes uniform engineering or technical specifications, criteria, methods, processes, or practices. Some standards are mandatory while others are voluntary. Voluntary standards are available if one chooses to for stereo television transmission In telecommunications, transmission is the process of sending, propagating and receiving an analogue or digital information signal over a physical point-to-point or point-to-multipoint transmission medium, either wired or wireless. Transmission technologies and schemes typically refer to physical layer protocol duties such as modulation,.

Q. I have an old console record player and am/fm radio combination. I think its from the 1950's. The cereal number has been worn off of the bottom. Its a micromatic magnovox with stereophonic high fidelity. That is pretty much all of the identifying markers it has. It has worked beautifuly for the 3 years I have had it until now. Could moving it to our new house have caused the problems? The problem is when I put the needle down on the record there isn't any sound. My husband put a coin on the head of the needle, it played but the music sounded distorted. Is this something that can be fixed? If so where do I go to get it fixed? Also, how do I know if the repair person is knowledgable or taking me for a ride?

A. First, never put a coin on the phono arm. It puts too much weight on the needle, causing it to dig into your vinyl record and damaging the hi-fidelity. The whole purpose of the needle is to be as light as possible and still have enough weight to actually make contact with the grooves. From your description, it sounds like the needle itself has not only worn down, but completely lost its point and you're dragging blunt metal across the delicate grooves of your record. The next likelihood of malfunction is the cartridge in the phono arm. They go dead and need to be replaced. It may be that you need both the needle and cartridge to be replaced. And then there are the tubes in your amplifier. I doubt that any of those are your… [cont.]
