Holophonics
Holophonics is a binaural recording system created by Hugo Zuccarelli that is based on the claim that the human auditory system acts as an interferometer. It relies on phase variance, just like stereophonic sound. The sound characteristics of holophonics are most clearly heard through headphones, though they can be effectively demonstrated with two-channel stereo speakers, provided that they are phase-coherent. The word "holophonics" is related to "acoustic hologram". History Holophonics was created by Argentine inventor Hugo Zuccarelli in 1980, during his studies at the Politecnico di Milano university. In 1983, Zuccarelli released a recording entitled ''Zuccarelli Holophonics (The Matchbox Shaker)'' in the United Kingdom (UK) that was produced by CBS. The recording consisted entirely of short recordings of sounds designed to show off the Holophonics system. These included a shaking matchbox, haircut and blower, bees, balloon, plastic bag, birds, airplanes, fireworks, thunde ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dreams Less Sweet
''Dreams Less Sweet'' is the second studio album by English experimental band Psychic TV, released in 1983. It was the last Psychic TV album to feature co-founder Peter "Sleazy" Christopherson. Recording The album was recorded using Zuccarelli Holophonics technology, a binaural recording system optimized for headphone listening also used by Pink Floyd on '' The Final Cut''. The band took advantage of the spatial effect (sometimes described as 3D) achieved by Holophonics to record in unusual locations like The Hellfire Club caves, Christ Church in Hampstead, and Caxton Hall. "Always Is Always" is the Charles Manson composition also known as "Always Is Always Forever" and "I'll Never Say No to Always". "White Nights" incorporates lyrics derived from the last sermon of cult leader Jim Jones. The "Eden" suite incorporates a recording of body art pioneer Mr. Sebastian reassuring Psychic TV associate John Balance about a tattoo he is about to give him. A demo version ( ...

Pink Floyd
Pink Floyd are an English rock band formed in London in 1965. Gaining an early following as one of the first British psychedelic music, psychedelic groups, they were distinguished by their extended compositions, sonic experimentation, philosophical lyrics and elaborate Pink Floyd live performances, live shows. They became a leading band of the progressive rock genre, cited by some as the greatest progressive rock band of all time. Pink Floyd were founded in 1965 by Syd Barrett (guitar, lead vocals), Nick Mason (drums), Roger Waters (bass guitar, vocals), and Richard Wright (musician), Richard Wright (keyboards, vocals). Under Barrett's leadership, they released two charting singles and the successful debut album ''The Piper at the Gates of Dawn'' (1967). Guitarist and vocalist David Gilmour joined in December 1967; Barrett left in April 1968 due to deteriorating mental health. Waters became the primary lyricist and thematic leader, devising the concept album, concepts behind ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Final Cut (album)
''The Final Cut'' is the twelfth studio album by English rock band Pink Floyd, released on 21 March 1983 through Harvest and Columbia Records. It comprises unused material from the band's previous studio album, ''The Wall'' (1979), alongside new material recorded throughout 1982. ''The Final Cut'' was the last Pink Floyd album to feature founding member Roger Waters, who departed from the band in 1985. It is also the only Pink Floyd album not to feature founding member and keyboardist Richard Wright, who had left the band under pressure from Waters after the ''Wall'' sessions. The recording was plagued by conflict; guitarist David Gilmour felt many of the tracks were not worthy of inclusion, but Waters accused him of failing to contribute material himself. Drummer Nick Mason's contributions were mostly limited to sound effects. Waters planned the album as a soundtrack for the 1982 film adaptation of ''The Wall''. With the onset of the Falklands War, he rewrote it as a concept ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Binaural Recording
Binaural recording is a method of recording sound that uses two microphones, arranged with the intent to create a 3-D stereo sound sensation for the listener of actually being in the room with the performers or instruments. This effect is often created using a technique known as dummy head recording, wherein a mannequin head is fitted with a microphone in each ear. Binaural recording is intended for replay using headphones and will not translate properly over stereo speakers. This idea of a three-dimensional or "internal" form of sound has also translated into useful advancement of technology in many things such as stethoscopes creating "in-head" acoustics and IMAX movies being able to create a three-dimensional acoustic experience. The term "binaural" has frequently been confused as a synonym for the word "stereo", due in part to systematic misuse in the mid-1950s by the recording industry, as a marketing buzzword. Conventional stereo recordings do not factor in natural ea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sound Recording
Sound recording and reproduction is the electrical, 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 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, which is then converted to a ...

Argentine Inventions
Argentines (mistakenly translated Argentineans in the past; in Spanish ( masculine) or ( feminine)) are people identified with the country of Argentina. This connection may be residential, legal, historical or cultural. For most Argentines, several (or all) of these connections exist and are collectively the source of their being ''Argentine''. Argentina is a multiethnic and multilingual society, home to people of various ethnic, religious, and national origins, with the majority of the population made up of Old World immigrants and their descendants. As a result, Argentines do not equate their nationality with ethnicity, but with citizenship and allegiance to Argentina. Aside from the indigenous population, nearly all Argentines or their ancestors immigrated within the past five centuries. Among countries in the world that have received the most immigrants in modern history, Argentina, with 6.6 million, ranks second to the United States (27 million), and ahead of other imm ...

The Pros And Cons Of Hitchhiking
''The Pros and Cons of Hitch Hiking'' is the debut solo studio album by English singer and musician Roger Waters; it was released in 1984, the year before Waters announced his departure from Pink Floyd. The album was certified gold in the United States by the Recording Industry Association of America in April 1995. Concept history and production The concept was originally envisioned by Waters in 1977 and refined in the early 1980s. In its completed form, it rotates around a man's scattered thoughts during his midlife crisis. These are explored on a dream journey during which he takes a road trip through California, commits adultery with a hitchhiker he picks up along the way, attempts to reconcile with his wife by moving to the wilderness, and finally ends up alone but with greater insight into a common human compassion. Along the way he also faces other fears and paranoia. The entire story is framed in real time as a fitful dream taking place in the early morning hour ...

Keep Under Cover
A keep (from the Middle English ''kype'') is a type of fortified tower built within castles during the Middle Ages by European nobility. Scholars have debated the scope of the word ''keep'', but usually consider it to refer to large towers in castles that were fortified residences, used as a refuge of last resort should the rest of the castle fall to an adversary. The first keeps were made of timber and formed a key part of the motte-and-bailey castles that emerged in Normandy and Anjou during the 10th century; the design spread to England, south Italy and Sicily. As a result of the Norman invasion of 1066, use spread into Wales during the second half of the 11th century and into Ireland in the 1170s. The Anglo-Normans and French rulers began to build stone keeps during the 10th and 11th centuries; these included Norman keeps, with a square or rectangular design, and circular shell keeps. Stone keeps carried considerable political as well as military importance and could take up ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HRTF
A head-related transfer function (HRTF), also known as anatomical transfer function (ATF), is a response that characterizes how an ear receives a sound from a point in space. As sound strikes the listener, the size and shape of the head, ears, ear canal, density of the head, size and shape of nasal and oral cavities, all transform the sound and affect how it is perceived, boosting some frequencies and attenuating others. Generally speaking, the HRTF boosts frequencies from 2–5 kHz with a primary resonance of +17 dB at 2,700 Hz. But the response curve is more complex than a single bump, affects a broad frequency spectrum, and varies significantly from person to person. A pair of HRTFs for two ears can be used to synthesize a binaural sound that seems to come from a particular point in space. It is a transfer function, describing how a sound from a specific point will arrive at the ear (generally at the outer end of the auditory canal). Some consumer home entertai ...

Otoacoustic Emission
An otoacoustic emission (OAE) is a sound that is generated from within the inner ear. Having been predicted by Austrian astrophysicist Thomas Gold in 1948, its existence was first demonstrated experimentally by British physicist David Kemp in 1978, and otoacoustic emissions have since been shown to arise through a number of different cellular and mechanical causes within the inner ear. Studies have shown that OAEs disappear after the inner ear has been damaged, so OAEs are often used in the laboratory and the clinic as a measure of inner ear health. Broadly speaking, there are two types of otoacoustic emissions: spontaneous otoacoustic emissions (SOAEs), which occur without external stimulation, and evoked otoacoustic emissions (EOAEs), which require an evoking stimulus. Mechanism of occurrence OAEs are considered to be related to the amplification function of the cochlea. In the absence of external stimulation, the activity of the cochlear amplifier increases, leading to the prod ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
