Duophonic
Duophonic sound was a trade name for a type of audio signal processing used by Capitol Records on certain releases and re-releases of mono recordings issued during the 1960s and 1970s. In this process monaural recordings were reprocessed into a type of artificial stereo. Generically, the sound is commonly known as fake stereo or mock stereo. This was done by splitting the mono signal into two channels, then delaying one channel's signal by means of delay lines and other circuits, i.e. desynchronizing the two channels by fractions of a second, and cutting the bass frequencies in one channel with a high-pass filter, then cutting the treble frequencies in the other channel with a low-pass filter. The result was an artificial stereo effect, without giving the listener the true directional sound characteristics of real stereo. In some cases, the effect was enhanced with reverberation and other technical tricks, sometimes adding stereo echo to mono tracks in an attempt to fool the lis ...

Only A Northern Song
"Only a Northern Song" is a song by the English rock band the Beatles from their 1969 soundtrack album '' Yellow Submarine''. Written by George Harrison, it was the first of four songs the band provided for the 1968 animated film '' Yellow Submarine'', to meet their contractual obligations to United Artists. The song was recorded mainly in February 1967, during the sessions for '' Sgt. Pepper's Lonely Hearts Club Band'', but the Beatles chose not to include it on that album. The group completed the recording two months later, straight after finishing work on ''Sgt. Pepper''. Harrison wrote "Only a Northern Song" out of dissatisfaction with his status as a junior songwriter with the Beatles' publishing company, Northern Songs. The lyrics and music convey his disenchantment at how the company retained the copyright for the songs it published, and at how, following its public listing in 1965, the major shareholders profited more from his compositions than he did. The recording fea ...

The Capitol Albums, Volume 2
''The Capitol Albums, Volume 2'' is a box set compilation composed of the Beatles' 1965 American Capitol Records releases. The set, which contains stereo and mono versions of all 92 tracks (with all of the tracks on ''The Early Beatles'' and many of the tracks on ''Beatles VI'' being released in stereo on compact disc for the first time), was announced on 22 March 2006. Differences between the stereo and mono mixes are one of the main draws for collectors. There are also a few significant musical differences to other versions of these recordings, such as a false start on the stereo version of "I'm Looking Through You". As with ''The Capitol Albums, Volume 1'', the CDs did not contain the original George Martin mixes released in Britain in the 1960s. Instead, the CDs were mastered from tapes prepared by Capitol A&R executive Dave Dexter, Jr., who, in 1965 took sub-master tapes from Capitol Records' vaults and added reverb to several tracks and simulated stereo on some mono ...

Audio Signal Processing
Audio signal processing is a subfield of signal processing that is concerned with the electronic manipulation of audio signals. Audio signals are electronic representations of sound waves—longitudinal waves which travel through air, consisting of compressions and rarefactions. The energy contained in audio signals is typically measured in decibels. As audio signals may be represented in either digital or analog format, processing may occur in either domain. Analog processors operate directly on the electrical signal, while digital processors operate mathematically on its digital representation. History The motivation for audio signal processing began at the beginning of the 20th century with inventions like the telephone, phonograph, and radio that allowed for the transmission and storage of audio signals. Audio processing was necessary for early radio broadcasting, as there were many problems with studio-to-transmitter links. The theory of signal processing and its appli ...

Love (The Beatles Album)
''Love'' is a soundtrack remix album of music recorded by the Beatles, released in November 2006. It features music compiled and remixed as a mashup for the Cirque du Soleil show of the same name. The album was produced by George Martin and his son Giles Martin, who said, "What people will be hearing on the album is a new experience, a way of re-living the whole Beatles musical lifespan in a very condensed period." The album was also George Martin's final album as a producer before his death in 2016. Background George Martin and his son Giles began work on ''Love'' after obtaining permission from Paul McCartney, Ringo Starr, Yoko Ono and Olivia Harrison (the latter two representing the estates of John Lennon and George Harrison, respectively). The idea for using the Beatles' music in a Cirque du Soleil production had originally come from Harrison, who died in November 2001, through his friendship with the company's founder, Guy Laliberté. Speaking to ''Mojo'' editor Jim ...

Precedence Effect
The precedence effect or law of the first wavefront is a binaural psychoacoustical effect. When a sound is followed by another sound separated by a sufficiently short time delay (below the listener's echo threshold), listeners perceive a single auditory event; its perceived spatial location is dominated by the location of the first-arriving sound (the first wave front). The lagging sound also affects the perceived location. However, its effect is suppressed by the first-arriving sound. The Haas effect was described in 1949 by Helmut Haas in his Ph.D. thesis. It is often equated with the underlying precedence effect. History Joseph Henry published "On The Limit of Perceptibility of a Direct and Reflected Sound" in 1851. The "law of the first wavefront" was described and named in 1948 by Lothar Cremer. The "precedence effect" was described and named in 1949 by Wallach et al. They showed that when two identical sounds are presented in close succession they will be heard as a s ...

'Round About Midnight
''Round About Midnight'' is an album by jazz trumpeter Miles Davis that was originally released by Columbia Records in March 1957. It was Davis' first album with Columbia. Background At the Newport Jazz Festival in 1955, Davis performed the song Round Midnight" as part of an all-star jam session, with the song's composer Thelonious Monk, along with Connie Kay and Percy Heath of the Modern Jazz Quartet, Zoot Sims, and Gerry Mulligan. Davis's solo received a positive reception from many jazz fans and critics. His response to this performance was typically laconic: "What are they talking about? I just played the way I always play." George Avakian of Columbia Records was in the audience, and his brother Aram persuaded him that he ought to sign Davis to the label. Davis signed with Columbia and formed his " first great quintet" with John Coltrane on saxophone. ''Round About Midnight'' was his first album for the label. He was still under contract to Prestige, but he had an agreement ...

Miles Davis
Miles Dewey Davis III (May 26, 1926September 28, 1991) was an American trumpeter, bandleader, and composer. He is among the most influential and acclaimed figures in the history of jazz and 20th-century music. Davis adopted a variety of musical directions in a five-decade career that kept him at the forefront of many major stylistic developments in jazz. Born in Alton, Illinois, and raised in East St. Louis, Davis left to study at Juilliard in New York City, before dropping out and making his professional debut as a member of saxophonist Charlie Parker's bebop quintet from 1944 to 1948. Shortly after, he recorded the ''Birth of the Cool'' sessions for Capitol Records, which were instrumental to the development of cool jazz. In the early 1950s, Davis recorded some of the earliest hard bop music while on Prestige Records but did so haphazardly due to a heroin addiction. After a widely acclaimed comeback performance at the Newport Jazz Festival, he signed a long-term contract wi ...
