Stereo Quadraphonic
SQ Quadraphonic ("Stereo Quadraphonic") was a matrix 4-channel quadraphonic sound system for vinyl LP records. It was introduced by CBS Records (known in the United States and Canada as Columbia Records) in 1971. Many recordings using this technology were released on LP during the 1970s. Record companies who adopted this format include: Angel, CTI, Columbia (internationally called CBS Records), EMI, Epic, Eurodisc, Harvest, HMV, Seraphim, Supraphon and Vanguard. With matrix formats, the four sound channels (forward left, forward right, back left, back right) are converted (encoded) down to two channels (left, right). These are then passed through a two-channel transmission medium (usually an LP record) before being decoded back to four channels and presented to four speakers. The SQ encoding is based on the work by Peter Scheiber and further developed by Benjamin Bauer. His basic formula used 90 degree phase shift circuitry to enable enhanced 4-2-4 matrix systems to be devel ...

Audio Engineering Society
The Audio Engineering Society (AES) is a professional body for engineers, scientists, other individuals with an interest or involvement in the professional audio industry. The membership largely comprises engineers developing devices or products for audio, and persons working in audio content production. It also includes acousticians, audiologists, academics, and those in other disciplines related to audio. The AES is the only worldwide professional society devoted exclusively to audio technology. Established in 1948, the Society develops, reviews and publishes engineering standards for the audio and related media industries, and produces the AES Conventions, which are held twice a year alternating between Europe and the US. The AES and individual regional or national ''sections'' also hold ''AES Conferences'' on different topics during the year. History The idea of a society dedicated solely to audio engineering had been discussed for some time before the first meeting, but was ...

Realistic (brand)
Realistic is a brand produced by RadioShack, a division of Tandy Corporation, to market audio and video products for home use. The brand name was phased out in the mid 1990s and discontinued in 2000, then returned briefly in 2016. History The brand began in 1954 under the name ''realist'', but was subsequently changed due to a prior camera trademark, Stereo Realist. The company's most notable products under the Realistic brand included the extensive line of TRC series Citizens Band radio transceivers, which dominated the CB Radio market during the 1970s, and included the Navaho series of CB base station units. A 1977 motion picture entitled ''Handle with Care (1977 film), Handle with Care'' was sponsored at the time by Tandy Corporation, in part to showcase the line. Also notable were their 8-track tape recorders under the TR- model line and their compact cassette decks under the SCT- model line. They are also the company responsible for the Realistic Mach speaker line. A very wide ...

QS Regular Matrix
Quadraphonic Sound (originally called Quadphonic Synthesizer, and later referred to as RM or Regular Matrix) was a matrix 4-channel quadraphonic sound system for phonograph records. The system was based on technology created by Peter Scheiber, but further developed by engineer Ryosuke Ito of Sansui in the early 1970s. The technology was freely licensed and was adopted by many record labels including ABC, Advent, BluesWay, Candide, Command, Decca, Impulse, Longines, MCA, Passport, Pye, Turnabout and Vox. Hundreds of recordings using this format were released on vinyl LP records during the 1970s. RM (''Regular Matrix'') was often used a synonym for QS, but was actually a standard set by the Japanese governing body, which also embraced the QM (''Quadraphonic Matrix'', consisting of Stereo-4 and Dynaquad) and QX (''QuadXtra'', based on D.H. Cooper "Dual-Triphonic") matrix systems. The QS matrix has been found to offer the advantages of excellent diagonal separation and stereo c ...

Dolby Pro Logic
Dolby Pro Logic is a surround sound processing technology developed by Dolby Laboratories, designed to decode soundtracks encoded with Dolby Surround. Dolby Stereo (also known as ''Dolby MP'' or ''Dolby SVA'') was developed by Dolby in 1976 for analog cinema sound systems. The format was adapted for home use in 1982 as Dolby Surround when HiFi capable consumer VCRs were introduced. It was further improved with the Dolby Pro Logic decoding system after 1987. The ''Dolby MP Matrix'' was the professional system that encoded four channels of film sound into two. This track used by the ''Dolby Stereo'' theater system on a 35mm optical stereo print and decoded back to the original 4.0 Surround. The same four-channel encoded stereo track was largely left unchanged and made available to consumers as ''"Dolby Surround"'' on home video. However, the original Dolby Surround decoders in 1982 were a simple passive matrix three-channel decoder: L/R and Mono Surround. The surround was limite ...

8-track Tape
The 8-track tape (formally Stereo 8; commonly called eight-track cartridge, eight-track tape, and eight-track) is a magnetic tape sound recording technology that was popular from the mid-1960s to the early 1980s, when the compact cassette, which pre-dated the 8-track system, surpassed it in popularity for pre-recorded music. The format was most popular in the United States, the United Kingdom, Canada, New Zealand, Australia, Mexico, Spain, France, Germany, Italy, Sweden and Japan. One advantage of the 8-track tape cartridge was that it could play continuously, and did not have to be "flipped over" to play the entire tape. It is now considered to be obsolete, although there are collectors that refurbish these tapes and players as well as some bands that issue these tapes as a novelty(Cheap Trick's "The Latest" in 2009 and Dolly Parton's "A Holly Dolly Christmas" in 2020 with a track that's only available on the 8 track) The Stereo 8 Cartridge was created in 1964 by a consorti ...

Center Channel
Center channel refers to an audio channel common to many surround sound formats. It is the channel that is mostly, or fully, dedicated to the reproduction of the dialogue of an audiovisual program. The speaker(s) connected to the center channel are placed in the center of and behind the perforated projection screen, to give the effect that sounds from the center channel are coming from the screen. In many home surround sound units, the center channel is positioned above or below the video screen. In the post-production process of filmmaking and video production sound editing, dialogue can be mapped to other speakers when story action and direction require it, such as when the person talking is off-screen, but it is rare that there is vocal content that is completely absent from the center channel. In material without accompanying visuals (e.g. music), the center channel simply reproduces sound intended to come from immediately in front of the listener, which usually includes the ...

Santana (band)
Santana is an American rock band formed in San Francisco in 1966 by American guitarist Carlos Santana. The band has undergone multiple recording and performing line-ups in its history, with Santana the only consistent member. After signing with Columbia Records, the band's appearance at the Woodstock Festival in 1969 increased their profile and went on to record the commercially successful and critically-acclaimed albums ''Santana'' (1969), ''Abraxas'' (1970), and ''Santana III'' (1971). These were recorded by the group's "classic" line-up, featuring Gregg Rolie, Michael Carabello, Michael Shrieve, David Brown, and José "Chepito" Areas. Hit songs of this period include "Evil Ways", "Black Magic Woman", "Oye Como Va", and the instrumental " Samba Pa Ti". Following a change in line-up and musical direction in 1972, the band experimented with elements of jazz fusion on '' Caravanserai'' (1972), ''Welcome'' (1973), and ''Borboletta'' (1974). Santana reached a new peak of commerc ...
