Outboard Gear
Musical outboard equipment or outboard gear is used to process or alter a sound signal separately from functionality provided within a mixing console or a digital audio workstation. Outboard effects units can be used either during a live performance or in the recording studio. Overview Some outboard effects units and digital signal processing (DSP) boxes commonly found in a studio are: *analog-to-digital and digital-to-analog converters *musical instrument digital interfaces (MIDIs) * microphone preamplifiers * equalizers *dynamics effects units: compressors/limiters, noise gates *time-based effects units: reverb, flanging, delay, echo, chorus etc. Devices The term ''outboard'' was originally used to describe a piece of audio equipment that existed outside of a studio or venue's primary analog mixing board. Today, analog effects are also considered ''outboard'' when used in conjunction with console-free computer-based digital recording systems. Famous examples include analog d ...

Mixing Console
A mixing console or mixing desk is an electronic device for Audio mixing (recorded music), mixing audio signals, used in sound recording and reproduction and sound reinforcement systems. Inputs to the console include microphones, signals from electric or electronic instruments, or recorded sounds. Mixers may control analog or Digital signal (signal processing), digital signals. The modified signals are summation, summed to produce the combined output signals, which can then be broadcast, amplified through a sound reinforcement system or recorded. Mixing consoles are used for applications including recording studios, public address systems, sound reinforcement systems, nightclubs, broadcasting, and post-production. A typical, simple application combines signals from microphones on stage into an amplifier that drives one set of loudspeakers for the audience. A DJ mixer may have only two channels, for mixing two phonograph, record players. A coffeehouse's tiny stage might only h ...

Echo (phenomenon)
In audio signal processing and acoustics, an echo is a reflection of sound that arrives at the listener with a delay after the direct sound. The delay is directly proportional to the distance of the reflecting surface from the source and the listener. Typical examples are the echo produced by the bottom of a well, by a building, or by the walls of an enclosed room and an empty room. A true echo is a single reflection of the sound source. The word ''echo'' derives from the Greek ἠχώ (''ēchō''), itself from ἦχος (''ēchos''), "sound". Echo in the Greek folk story is a mountain nymph whose ability to speak was cursed, leaving her able only to repeat the last words spoken to her. Some animals use echo for location sensing and navigation, such as cetaceans (dolphins and whales) and bats in a process known as echolocation. Echoes are also the basis of Sonar technology. Acoustic phenomenon Acoustic waves are reflected by walls or other hard surfaces, such as mountains and pr ... [...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 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 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, among others. DSP can involve linear ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sound Production Technology
In physics, sound is a vibration that propagates as an acoustic wave, through a transmission medium such as a gas, liquid or solid. In human physiology and psychology, sound is the ''reception'' of such waves and their ''perception'' by the brain. Only acoustic waves that have frequencies lying between about 20 Hz and 20 kHz, the audio frequency range, elicit an auditory percept in humans. In air at atmospheric pressure, these represent sound waves with wavelengths of to . Sound waves above 20 kHz are known as ultrasound and are not audible to humans. Sound waves below 20 Hz are known as infrasound. Different animal species have varying hearing ranges. Acoustics Acoustics is the interdisciplinary science that deals with the study of mechanical waves in gasses, liquids, and solids including vibration, sound, ultrasound, and infrasound. A scientist who works in the field of acoustics is an ''acoustician'', while someone working in the field of acous ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Electronic Keyboard
An electronic keyboard, portable keyboard, or digital keyboard is an electronic musical instrument, an electronic derivative of keyboard instruments. Electronic keyboards include synthesizers, digital pianos, stage pianos, electronic organs and digital audio workstations. In technical terms, an electronic keyboard is a synthesizer with a low-wattage power amplifier and small loudspeakers. Electronic keyboards are capable of recreating a wide range of instrument sounds (piano, Hammond organ, pipe organ, violin, etc.) and synthesizer tones with less complex sound synthesis. Electronic keyboards are usually designed for home users, beginners and other non-professional users. They typically have unweighted keys. The least expensive models do not have velocity-sensitive keys, but mid- to high-priced models do. Home keyboards typically have little, if any, digital sound editing capacity. The user typically selects from a range of preset "voices" or sounds, which include imit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MIDI
MIDI (; Musical Instrument Digital Interface) is a technical standard that describes a communications protocol, digital interface, and electrical connectors that connect a wide variety of electronic musical instruments, computers, and related audio devices for playing, editing, and recording music. The specification originates in the paper ''Universal Synthesizer Interface'' published by Dave Smith and Chet Wood of Sequential Circuits at the 1981 Audio Engineering Society conference in New York City. A single MIDI cable can carry up to sixteen channels of MIDI data, each of which can be routed to a separate device. Each interaction with a key, button, knob or slider is converted into a MIDI event, which specifies musical instructions, such as a note's pitch, timing and loudness. One common MIDI application is to play a MIDI keyboard or other controller and use it to trigger a digital sound module (which contains synthesized musical sounds) to generate sounds, wh ...

Lexicon
A lexicon is the vocabulary of a language or branch of knowledge (such as nautical or medical). In linguistics, a lexicon is a language's inventory of lexemes. The word ''lexicon'' derives from Greek word (), neuter of () meaning 'of or for words'. Linguistic theories generally regard human languages as consisting of two parts: a lexicon, essentially a catalogue of a language's words (its wordstock); and a grammar, a system of rules which allow for the combination of those words into meaningful sentences. The lexicon is also thought to include bound morphemes, which cannot stand alone as words (such as most affixes). In some analyses, compound words and certain classes of idiomatic expressions, collocations and other phrases are also considered to be part of the lexicon. Dictionaries are lists of the lexicon, in alphabetical order, of a given language; usually, however, bound morphemes are not included. Size and organization Items in the lexicon are called lexemes, l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elektro-Mess-Technik
Elektromesstechnik (EMT) is a manufacturer of phonograph turntables and professional audio equipment, including a well-regarded line of artificial reverberation devices beginning with the EMT 140 plate reverb. The company was founded by Wilhelm Franz. Founding Wilhelm Franz, born in Bremen in 1913, founded Elektromesstechnik Wilhelm Franz K.G. in Berlin in 1938. Two years later Wilhelm’s brother, Walter, joined the company. The Allied bombing air raids over Berlin intensified in 1943 and Franz moved to Schuttertal, then, after 1945, to Lahr, in the Schwarzwald region of south-western Germany. The logo of an 'arrowhead' was chosen as a symbol of the passage of an electric signal in an electronic circuitry. Reverb effects 140 Plate Reverb In 1957, EMT introduced the ’140’ Reverberation Unit, an electro-mechanical reverberation device that offered an alternative to the spring reverbs and echo chambers of the era. The EMT 140 used a 1 meter-tall by 2 meters-wide steel plat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 Fa ...

1176 Peak Limiter
The 1176 Peak Limiter is a dynamic range compressor designed by Bill Putnam and introduced by UREI in 1967. Derived from the 175 and 176 tube compressors, it marked the transition from vacuum tubes to solid-state technology. With its distinctive tone and its wide range of sounds, deriving from the Class A amplifiers, its input and output transformers, the uncommonly fast attack and release times and their program dependence, and different compression ratios and modes, the 1176 was immediately appreciated by engineers and producers and established as a studio standard through the years. At the time of its introduction, it was the first true peak limiter with all solid-state circuitry. The 1176LN was inducted into the TECnology Hall of Fame in 2008. History In 1966, Bill Putnam, engineer and founder of Universal Audio, began to employ the recently invented field-effect transistors (FET), replacing vacuum tubes in his equipment designs. After successfully adapting the 108 tube ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
LA-2A Leveling Amplifier
The LA-2A Leveling Amplifier is an audio compressor produced by Teletronix Engineering Company from 1965 until 1969, and reissued in 2000 by Universal Audio. History The LA-2A was invented by James F. Lawrence II, founder of the Teletronix Engineering Company in Pasadena, California in the early 1960s. The LA-2A had evolved from Lawrence's first leveling amplifier, the LA-1, which was favored by Gene Autry, and its successor, the LA-2, which had been adopted by CBS and RCA. In 1965, Lawrence sold Teletronix to Babcock Electronics of Costa Mesa, California, and in 1967 Bill Putnam's company Studio Electronics (eventually renamed UREI), acquired Babcock's broadcast division, including the Teletronix brand. Three versions of the LA-2A were made until 1969. After Universal Audio was re-established in 1999, the company re-issued an updated version of the LA-2A. The LA-2A was inducted into the TECnology Hall of Fame in 2004. Design The LA-2A is a hand-wired, tube-based compres ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
