Phased Array Radiation Pattern
A phaser is an electronic sound processor used to filter a signal by creating a series of peaks and troughs in the frequency spectrum. The position of the peaks and troughs of the waveform being affected is 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. 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 the depth of the notches; the deepest notches occur when the mix ratio is 50%. The def ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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] |

Digital Signal Processing
Digital signal processing (DSP) is the use of digital processing, such as by computers or more specialized digital signal processors, to perform a wide variety of signal processing operations. The digital signals processed in this manner are a sequence of numbers that represent Sampling (signal processing), samples of a continuous variable in a domain such as time, space, or frequency. In digital electronics, a digital signal is represented as a pulse train, which is typically generated by the switching of a transistor. Digital signal processing and analog signal processing are subfields of signal processing. DSP applications include Audio signal processing, audio and speech processing, sonar, radar and other sensor array processing, spectral density estimation, statistical signal processing, digital image processing, data compression, video coding, audio coding, image compression, signal processing for telecommunications, control systems, biomedical engineering, and seismology ...

Electric Guitar
An electric guitar is a guitar that requires external electric Guitar amplifier, sound amplification in order to be heard at typical performance volumes, unlike a standard acoustic guitar. It uses one or more pickup (music technology), pickups to convert the vibration of its strings into Electrical signal, electrical signals, which ultimately are reproduced as sound by loudspeakers. The sound is sometimes shaped or electronically altered to achieve different timbres or tonal qualities via amplifier settings or knobs on the guitar. Often, this is done through the use of Effects unit, effects such as reverb, Distortion (music), distortion and "overdrive"; the latter is considered to be a key element of electric blues guitar music and jazz, rock music, rock and Heavy metal music, heavy metal guitar playing. Designs also exist combining attributes of electric and acoustic guitars: the Semi-acoustic guitar, semi-acoustic and Acoustic-electric guitar, acoustic-electric guitars. Inven ...

Todd Rundgren
Todd Harry Rundgren (born June 22, 1948) is an American musician, singer, songwriter, and record producer who has performed a diverse range of styles as a solo artist and as a member of the bands Nazz and Utopia. He is known for his sophisticated and often unorthodox music, his occasionally lavish stage shows, and his later experiments with interactive art. 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. After two years, 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 time on classic rock radio stations, the 1978 " C ...

Led Zeppelin
Led Zeppelin were an English rock music, rock band formed in London in 1968. The band comprised vocalist Robert Plant, guitarist Jimmy Page, bassist-keyboardist John Paul Jones (musician), John Paul Jones and drummer John Bonham. With a heavy, guitar-driven sound and drawing from influences including blues and folk music, Led Zeppelin are cited as a progenitor of hard rock and heavy metal music, heavy metal. They significantly influenced the music industry, particularly in the development of album-oriented rock and stadium rock. Led Zeppelin evolved from a previous band, the Yardbirds, and were originally named "the New Yardbirds". They 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 (album), Led Zeppelin'', was a top-ten album in several countries and features such tracks as "Good Times Ba ...

Itchycoo Park
"Itchycoo Park" is a song by English rock band Small Faces, written by Steve Marriott and Ronnie Lane. Largely written by Lane, it was among a number of pop songs of the era to make use of flanging, an effect involving, at that time, electro-mechanical processes. The song was not included on any of their UK albums, but was however featured on the North American release ''There Are But Four Small Faces'' (1968). Released on 4 August 1967 by Immediate Records, the song was 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 US Billboard Hot 100, ''Billboard'' Hot 100 in early 1968. In Continental Europe, it reached the top ten in several countries, while in Canada and New Zealand it was a number one hit.

Psychedelia
Psychedelia usually refers to a Aesthetics, style or aesthetic that is resembled in the psychedelic subculture of the 1960s and the psychedelic experience produced by certain psychoactive substances. 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 psilocybin mushroom, 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 distortion, distorted, Surrealism, surreal visuals, bright colors and full spectrums and animation (including cartoons) to evoke, convey, or enhance the psychedelic experience. Psychedelic music uses distortion (music), distorted electric guitar, Indian music elements such as the sitar and tabla, effects unit, electronic effects, sou ...

Flanging
Flanging is an audio signal processing, audio effect produced by mixing two identical audio signal, 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 (music), 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 (audio effect), delay line), producing a resonance effect that 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-differ ...
