Phasing
A phaser is an electronic sound processor used to filter a signal, and it has a series of troughs in its frequency-attenutation graph. The position (in Hz) of the peaks and troughs are typically modulated by an internal low-frequency oscillator so that they vary over time, creating a sweeping effect. Phasers are often used to give a "synthesized" or electronic effect to natural sounds, such as human speech. The voice of C-3PO from ''Star Wars'' was created by taking the actor's voice and treating it with a phaser. Process The electronic phasing effect is created by splitting an audio signal into two paths. One path treats the signal with an all-pass filter, which preserves the amplitude of the original signal and alters the phase. The amount of change in phase depends on the frequency. When signals from the two paths are mixed, the frequencies that are out of phase will cancel each other out, creating the phaser's characteristic notches. Changing the mix ratio changes ...

Flanging
Flanging is an audio effect produced by mixing two identical signals together, one signal delayed by a small and (usually) gradually changing period, usually smaller than 20 milliseconds. This produces a swept comb filter effect: peaks and notches are produced in the resulting frequency spectrum, related to each other in a linear harmonic series. Varying the time delay causes these to sweep up and down the frequency spectrum. A flanger is an effects unit that creates this effect. Part of the output signal is usually fed back to the input (a "re-circulating delay line"), producing a resonance effect which further enhances the intensity of the peaks and troughs. The phase of the fed-back signal is sometimes inverted, producing another variation on the flanger sound. Origin As an audio effect, a listener hears a "drainpipe" or "swoosh" or "jet plane" sweeping effect as shifting sum-and-difference harmonics are created analogous to use of a variable notch filter.

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 a ...

Quadrature Phase
In physics and mathematics, the phase of a periodic function F of some real variable t (such as time) is an angle-like quantity representing the fraction of the cycle covered up to t. It is denoted \phi(t) and expressed in such a scale that it varies by one full turn as the variable t goes through each period (and F(t) goes through each complete cycle). It may be measured in any angular unit such as degrees or radians, thus increasing by 360° or 2\pi as the variable t completes a full period. This convention is especially appropriate for a sinusoidal function, since its value at any argument t then can be expressed as \phi(t), the sine of the phase, multiplied by some factor (the amplitude of the sinusoid). (The cosine may be used instead of sine, depending on where one considers each period to start.) Usually, whole turns are ignored when expressing the phase; so that \phi(t) is also a periodic function, with the same period as F, that repeatedly scans the same range o ...

Todd Rundgren
Todd Harry Rundgren (born June 22, 1948) is an American multi-instrumentalist, singer, songwriter, multimedia artist, sound engineer and record producer who has performed a diverse range of styles as a solo artist and as a member of the band Utopia. He is known for his sophisticated and often unorthodox music, his occasionally lavish stage shows, and his later experiments with interactive entertainment. He also produced music videos and was an early adopter and promoter of various computer technologies, such as using the Internet as a means of music distribution in the late 1990s. A native of Philadelphia, Rundgren began his professional career in the mid 1960s, forming the psychedelic band Nazz in 1967. Two years later, he left Nazz to pursue a solo career and immediately scored his first US top 40 hit with " We Gotta Get You a Woman" (1970). His best-known songs include " Hello It's Me" and " I Saw the Light" from '' Something/Anything?'' (1972), which get frequent air ti ...

Led Zeppelin
Led Zeppelin were an English rock band formed in London in 1968. The group comprised vocalist Robert Plant, guitarist Jimmy Page, bassist/keyboardist John Paul Jones, and drummer John Bonham. With a heavy, guitar-driven sound, they are cited as one of the progenitors of hard rock and heavy metal, although their style drew from a variety of influences, including blues and folk music. Led Zeppelin have been credited as significantly impacting the nature of the music industry, particularly in the development of album-oriented rock (AOR) and stadium rock. Originally named the New Yardbirds, Led Zeppelin signed a deal with Atlantic Records that gave them considerable artistic freedom. Initially unpopular with critics, they achieved significant commercial success with eight studio albums over ten years. Their 1969 debut, '' Led Zeppelin'', was a top-ten album in several countries and featured such tracks as " Good Times Bad Times", " Dazed and Confused" and " Communicatio ...

Eventide, Inc
Eventide, Inc. (also known earlier as Eventide Clock Works Inc.) is an American audio, broadcast and communications company whose audio division manufactures digital audio processors, digital signal processor (DSP) software, and guitar effects. Eventide was one of the first companies to manufacture digital audio processors, and its products are mainstays in sound recording and reproduction, post production, and broadcast studios. Beginnings Eventide was founded by recording engineer Stephen Katz, inventor Richard Factor, and businessman/patent attorney Orville Greene. The business was founded in the basement of the Sound Exchange, a recording studio located at 265 West 54th Street in New York City and owned by Greene. When Katz needed to rewind the analog tape back to a specific point on their Ampex MM1000 multitrack recorder, but limited space in the studio did not allow for a tape op (a person who would operate the tape recorder on behalf of the sound engineer), Katz asked F ...

Small Faces
Small Faces were an English rock band from London, founded in 1965. The group originally consisted of Steve Marriott, Ronnie Lane, Kenney Jones and Jimmy Winston, with Ian McLagan replacing Winston as the band's keyboardist in 1966. The band was one of the most acclaimed and influential mod groups of the 1960s, recording hit songs such as " Itchycoo Park", " Lazy Sunday", "All or Nothing" and " Tin Soldier", as well as their concept album ''Ogdens' Nut Gone Flake''. They evolved into one of the UK's most successful psychedelic bands until 1969. When Marriott left to form Humble Pie, the remaining three members collaborated with Ronnie Wood, Ronnie's older brother Art Wood, Rod Stewart and Kim Gardner, briefly continuing under the name Quiet Melon, and then, with the departure of Art Wood and Gardner, as Faces. In North America, Faces' debut album was credited to Small Faces. Following the breakup of both Faces and Humble Pie in 1975, the classic line-up of Small Fac ...

Itchycoo Park
"Itchycoo Park" is a song written by Steve Marriott and Ronnie Lane, first recorded by their group, the Small Faces. Largely written by Lane, it was one of the first music recordings to feature flanging, an effect at that time made possible by electro-mechanical processes. The location and etymology of the titular park has long been debated; many claiming it to be Little Ilford Park in Manor Park, East London, Valentine's Park in Ilford or Wanstead Flats in Wanstead, East London. The single was not featured on any of their UK albums, but was however featured on the North American release '' There Are But Four Small Faces''. Released on 4 August 1967 on Immediate Records, the song was the Small Faces' fifth top-ten song in the UK Singles Chart, reaching a position of number three. "Itchycoo Park" became the Small Faces' sole top-forty hit in the United States, reaching number sixteen on the Billboard Hot 100 in early 1968. In Continental Europe, it reached the top ten in s ...

Psychedelia
Psychedelia refers to the psychedelic subculture of the 1960s and the psychedelic experience. This includes psychedelic art, psychedelic music and style of dress during that era. This was primarily generated by people who used psychedelic drugs such as LSD, mescaline (found in peyote) and psilocybin (found in magic mushrooms) and also non-users who were participants and aficionados of this subculture. Psychedelic art and music typically recreate or reflect the experience of altered consciousness. Psychedelic art uses highly distorted, surreal visuals, bright colors and full spectrums and animation (including cartoons) to evoke, convey, or enhance the psychedelic experience. Psychedelic music uses distorted electric guitar, Indian music elements such as the sitar, tabla, electronic effects, sound effects and reverb, and elaborate studio effects, such as playing tapes backwards or panning the music from one side to another. A psychedelic experience is characteriz ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Stompbox
A stomp box (or stompbox) is a percussion instrument consisting of a small box placed under the foot, which is tapped or stamped on rhythmically to produce a sound similar to that of a bass drum. A stomp box allows a performer such as a singer or guitar player to create a simple rhythmic self-accompaniment. Stompboxes are most commonly used in American folk and blues music, but they are also used across the musical spectrum. There are commercially produced stomp boxes available, but performers often simply mount a dynamic microphone inside whatever wooden box they have handy. Some homemade stomp boxes include customized features such as a built-in preamp or equalizer. In 2010s-era use, a simple piezo transducer (or sometimes a microphone) is located inside the box to allow amplification of the stompbox's bass sound through the PA system or bass amplifier. Other stompboxes such as the PorchBoard Bass and the Peterman acoustic use magnetic sensors designed to produce lo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
