Live Sound Mixing
Live sound mixing is the blending of multiple sound sources by an audio engineer using a mixing console or software. Sounds that are mixed include those from instruments and voices which are picked up by microphones (for drum kit, lead vocals and acoustic instruments like piano or saxophone and pickups for instruments such as electric bass) and pre-recorded material, such as songs on CD or a digital audio player. Individual sources are typically equalised to adjust the bass and treble response and routed to effect processors to ultimately be amplified and reproduced via a loudspeaker system. The live sound engineer listens and balances the various audio sources in a way that best suits the needs of the event. Equipment Audio equipment is usually connected together in a sequence known as the signal chain. In live sound situations, this consists of input transducers like microphones, pickups, and DI boxes. These devices are connected, often via multicore cable, to individual ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HowStuffWorks
HowStuffWorks is an American commercial infotainment website founded by professor and author Marshall Brain, to provide its target audience an insight into the way many things work. The site uses various media to explain complex concepts, terminology, and mechanisms—including photographs, diagrams, videos, animations, and articles. The website was acquired by Discovery Communications in 2007 but was sold to Blucora in 2014. The site has since expanded out into podcasting, focusing on factual topics. In December 2016, HowStuffWorks, LLC became a subsidiary of OpenMail, LLC, later renamed System1. In 2018, the podcast division of the company, which had been spun-off by System1 under the name Stuff Media, was acquired by iHeartMedia for $55 million.

Autotune
Auto-Tune (or autotune) is an audio processor introduced in 1996 by American company Antares Audio Technologies. Auto-Tune uses a proprietary device to measure and alter pitch in vocal and instrumental music recording and performances. Auto-Tune was originally intended to disguise or correct off-key inaccuracies, allowing vocal tracks to be perfectly tuned despite originally being slightly off-pitch. The 1998 Cher song " Believe" popularized the technique of using Auto-Tune to distort vocals. In 2018, the music critic Simon Reynolds observed that Auto-Tune had "revolutionized popular music", calling its use for effects "the fad that just wouldn't fade. Its use is now more entrenched than ever." In its role distorting vocals, Auto-Tune operates on different principles from the vocoder or talk box and produces different results. Description Auto-Tune is available as a plug-in for digital audio workstations used in a studio setting and as a stand-alone, rack-mounted unit for ...

Rackmount
A 19-inch rack is a standardized frame or enclosure for mounting multiple electronic equipment modules. Each module has a front panel that is wide. The 19 inch dimension includes the edges or "ears" that protrude from each side of the equipment, allowing the module to be fastened to the rack frame with screws or bolts. Common uses include computer servers, telecommunications equipment and networking hardware, audiovisual production gear, and scientific equipment. Overview and history Equipment designed to be placed in a rack is typically described as rack-mount, rack-mount instrument, a rack-mounted system, a rack-mount chassis, subrack, rack cabinet, rack-mountable, or occasionally simply shelf. The height of the electronic modules is also standardized as multiples of or one rack unit or U (less commonly RU). The industry-standard rack cabinet is 42U tall; however, 45U racks are also common. The term ''relay rack'' appeared first in the world of telephony. By 1911, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Insert (effects Processing)
In audio processing and sound reinforcement, an insert is an access point built into the mixing console, allowing the audio engineer to add external line level devices into the signal flow between the microphone preamplifier and the mix bus. Common usages include gating, compressing, equalizing and for reverb effects that are specific to that channel or group. Inserts can be used as an alternate way to route signals such as for multitrack recording output or line level direct input. Insert jacks Inserts can be balanced or unbalanced. Typically, higher-end mixers will have balanced inserts and entry level mixers will have unbalanced inserts. Balanced inserts appear as a ''pair'' of jacks, one serving as the send (out from the mixer) and the other serving as the return (back to the mixer.) Balanced insert jacks can be XLR, 1/4" TRS phone connector or Bantam TT. Unbalanced inserts can also be a pair of jacks such as RCA or 1/4" TS (Tip Sleeve) phone connector. Again, one jack s ...

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 appli ...

Reverb
Reverberation (also known as reverb), in acoustics, is a persistence of sound, after a sound is produced. Reverberation is created when a sound or signal is reflected causing numerous reflections to build up and then decay as the sound is absorbed by the surfaces of objects in the space – which could include furniture, people, and air. This is most noticeable when the sound source stops but the reflections continue, their amplitude decreasing, until zero is reached. Reverberation is frequency dependent: the length of the decay, or reverberation time, receives special consideration in the architectural design of spaces which need to have specific reverberation times to achieve optimum performance for their intended activity. In comparison to a distinct echo, that is detectable at a minimum of 50 to 100 ms after the previous sound, reverberation is the occurrence of reflections that arrive in a sequence of less than approximately 50 ms. As time passes, the amplitude of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Effects Unit
An effects unit or effects pedal is an electronic device that alters the sound of a musical instrument or other audio source through audio signal processing. Common effects include distortion/overdrive, often used with electric guitar in electric blues and rock music; dynamic effects such as volume pedals and compressors, which affect loudness; filters such as wah-wah pedals and graphic equalizers, which modify frequency ranges; modulation effects, such as chorus, flangers and phasers; pitch effects such as pitch shifters; and time effects, such as reverb and delay, which create echoing sounds and emulate the sound of different spaces. Most modern effects use solid-state electronics or digital signal processors. Some effects, particularly older ones such as Leslie speakers and spring reverbs, use mechanical components or vacuum tubes. Effects are often used as stompboxes, typically placed on the floor and controlled with footswitches. They may also be built into guita ...

Multicore Cable
A multicore cable is a type of electrical cable that combines multiple signals or power feeds into a single jacketed cable. The term is normally only used in relation to a cable that has more cores than commonly encountered. Not all cables with multiple insulated conductors are called multicore cablesthe ''core'' in ''multicore'' refers to the number of usable connections made, not the number of conductors or wires. In most cases, a "usable connection" requires multiple conductors, such as the positive and negative conductors used for DC power. For example, a standard three-conductor mains cable is never referred to as multicore, but a cable comprising four coaxial cables in a single sheath would be considered multicore. Confusingly, the term ''multicore'' is occasionally used to refer to the number of individual conductors rather than the number of connections, especially in Europe. A cable with multiple conductors, but not a multicore cable, is usually called a ''multi-conducto ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DI Box
A DI unit (direct input or direct inject) is an electronic device typically used in recording studios and in sound reinforcement systems to connect a high-output impedance, line level, unbalanced output signal to a low-impedance, microphone level, balanced input, usually via an XLR connector and XLR cable. DIs are frequently used to connect an electric guitar or electric bass to a mixing console's microphone input jack. The DI performs level matching, balancing, and either active buffering or passive impedance matching/impedance bridging to minimize unwanted noise, distortion, and ground loops. DI units are typically metal boxes with input and output jacks and, for more expensive units, “ground lift” and attenuator switches. DI boxes are extensively used with professional and semi-professional PA systems, professional sound reinforcement systems and in sound recording studios. Manufacturers produce a wide range of units, from inexpensive, basic, passive units to expensive, s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pickup (music Technology)
A pickup is a transducer that captures or senses mechanical vibrations produced by musical instruments, particularly stringed instruments such as the electric guitar, and converts these to an electrical signal that is amplified using an instrument amplifier to produce musical sounds through a loudspeaker in a speaker enclosure. The signal from a pickup can also be recorded directly. Most electric guitars and electric basses use magnetic pickups. Acoustic guitars, upright basses and fiddles often use a piezoelectric pickup. Magnetic pickups A typical magnetic pickup is a transducer (specifically a variable reluctance sensor) that consists of one or more permanent magnets (usually alnico or ferrite) wrapped with a coil of several thousand turns of fine enameled copper wire. The magnet creates a magnetic field which is focused by the pickup's pole piece or pieces. The permanent magnet in the pickup magnetizes the guitar string above it. This causes the string to generate a ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
