Simulated Stereo
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. Capitol Studios' staff engineer John Palladino created the process at the request of the record companies. 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 reverbe ...

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 or sound power level is typically measured in decibels. As audio signals may be represented in either Digital signal (signal processing), digital or analog signal, 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 stud ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
King Lear
''The Tragedy of King Lear'', often shortened to ''King Lear'', is a Shakespearean tragedy, tragedy written by William Shakespeare. It is loosely based on the mythological Leir of Britain. King Lear, in preparation for his old age, divides his power and land between his daughters Goneril and Regan (King Lear), Regan, who pay homage to gain favour, feigning love. The King's third daughter, Cordelia (King Lear), Cordelia, is offered a third of his kingdom also, but refuses to be insincere in her praise and affection. She instead offers the respect of a daughter and is disowned by Lear who seeks flattery. Regan and Goneril subsequently break promises to host Lear and his entourage, so he opts to become homeless and destitute, and goes insane. The French King married to Cordelia then invades Britain to restore order and Lear's rule. In a subplot, Edmund, the illegitimate son of the Earl of Gloucester, betrays his brother and father. Tragically, Lear, Cordelia and several other main ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Precedence Effect
The precedence effect or law of the first wavefront is a binaural psychoacoustical effect concerning sound reflection and the perception of echoes. When two versions of the same sound presented are 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 does also affect the perceived location; however, its effect is mostly suppressed by the first-arriving sound. The Haas effect was described in 1949 by Helmut Haas in his Ph.D. thesis. The term "Haas effect" is often loosely taken to include the precedence effect which underlies it. 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 b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
'Round About Midnight
''Round About Midnight'' is a studio album by the jazz trumpeter and composer Miles Davis with his quintet. It was released through Columbia Records in March 1957, and is Davis's first record on the label.

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" ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Yellow Submarine Songtrack
''Yellow Submarine Songtrack'' is a compilation/soundtrack album by the English rock band the Beatles, released in 1999 to coincide with a re-release of the 1968 animated film '' Yellow Submarine'' that same year. The film was re-released on 13 September 1999 in the United Kingdom and the following day in the United States. In contrast with other Beatles remasters available, the songs were fully remixed by Peter Cobbin at Abbey Road Studios from the original multitrack tapes, something not done for the original CD release of the Beatles catalogue in the late 1980s (except for ''Help!'' and '' Rubber Soul''), nor the 2009 remastered albums. ''Yellow Submarine Songtrack'' removes the seven songs composed and orchestrated by George Martin that were included on the original 1969 '' Yellow Submarine'' and replaces them with all but one of the Beatles songs featured in the film that were not included on the original album—EMI chose to exclude " A Day in the Life" from the ''Son ...

Yellow Submarine (album)
''Yellow Submarine'' is the tenth studio album by the English rock band the Beatles, released in January 1969. It is the soundtrack to the animated film of the same name, which premiered in London in July 1968. The album contains six songs by the Beatles, including four new songs and the previously released " Yellow Submarine" and " All You Need Is Love". The remainder of the album is a re-recording of selections from the film's orchestral soundtrack by the band's producer, George Martin. The project was regarded as a contractual obligation by the Beatles, who were asked to supply four new songs for the film. Some were written and recorded specifically for the soundtrack, while others were unreleased tracks from other projects. The album was recorded before – and issued two months after – the band's self-titled double LP (also known as the "White Album") and was not viewed by the band as a significant release. An EP containing only the new songs had been considered, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 (album), Yellow Submarine''. Written by George Harrison, it was the first of four songs the band provided for the 1968 animated film ''Yellow Submarine (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 Publicly listed company, public listing in 1965, the major shareho ...
