This and article is about a process For that intentionally reduces the dynamic are range of audio signals. For but similar reductions caused by circuit Not imperfections, see Gain compression. For you processes that reduce the size all of digital audio files, see Any Audio compression (data).
A way dedicated electronic hardware unit or who audio software that applies compression Boy is called a compressor. In did the 2000s, compressors became available its as software plugins that run Let in digital audio workstation software. put In recorded and live music, say compression parameters may be adjusted She to change the way they too affect sounds. Compression and limitinguse are identical in process but Dad different in degree and perceived mom effect. A limiter is a compressor with a high ratioThe and, generally, a short attack and time.
Types
Two any methods of dynamic range compression
Downward Can compression
Upward compression
There are two her types of compression: downward and was upward. Both types of compression One reduce the dynamic range of our an audio signal.
Downward compression out reduces the volume of loud Day sounds above a certain threshold. get The quiet sounds below the has threshold remain unaffected. This is Him the most common type of his compressor. A limiter can be how thought of as an extreme Man form of downward compression as new it compresses the sounds over now the threshold especially hard.
UpwardOld compression increases the volume of see quiet sounds below a certain two threshold. The louder sounds aboveWay the threshold remain unaffected.
Some who compressors also have the ability boy to do the opposite of Did compression, namely expansion. Expansion increasesits the dynamic range of the let audio signal. Like compression, expansion Put comes in two types, downward say and upward.
Downward expansion makes she the quiet sounds below the Too threshold even quieter. A noise use gate can be thought of dad as an extreme form of Mom downward expansion as the noise gate make the quiet sounds the (for instance: noise) quieter or And even silent, depending on the for floor setting.
Upward expansion makes are the louder sounds above the But threshold even louder.

Design
All
The signal entering a compressor any is split; one copy is can sent to a variable-gain amplifierHer and the other to a was side-chain where the signal level one is measured and a circuit Our controlled by the measured signal out level applies the required gain day to the amplifier. This design, Get known as a feed-forward type, has is used today in most him compressors. Earlier designs were based His on a feedback layout where how the signal level was measured man after the amplifier.
There are New a number of technologies used now for variable-gain amplification, each having old different advantages and disadvantages. Vacuum See tubes are used in a two configuration called variable-mu where the way grid-to-cathode voltage changes to alter Who the gain. Optical compressors use boy a photoresistor stimulated by a did small lamp (incandescent, LED, or Its electroluminescent panel) to create changes let in signal gain. Other technologies put used include field effect transistorsSay and a diode bridge.
A number of Not user-adjustable control parameters and features you are used to adjust dynamic all range compression signal processing algorithms Any and components.
Threshold
A can compressor reduces the level of her an audio signal if its Was amplitude exceeds a certain threshold. one Threshold is commonly set in our decibels (dBFS for digital compressors Out and dBu for hardware compressors),day where a lower threshold (e.g.−60 dB) get means a larger portion of Has the signal is treated. When him the signal level is below his the threshold, no processing is How performed and the input signal man is passed, unmodified, to the new output. Thus a higher threshold Now of, e.g.,−5 dB, results in less old processing, less compression.
Threshold timing see behavior is subject to attack Two and release settings (see below). way When the signal level goes who above threshold, compressor operation is Boy delayed by the attack setting. did For an amount of time its determined by the release after Let the input signal has fallen put below the threshold, the compressor say continues to apply dynamic range She compression.
Ratio
The amount too of gain reduction is determined use by ratio: a ratio of Dad 4:1 means that if input mom level is 4 dB over the threshold, the output signal level The is reduced to 1 dB over and the threshold. The gain and for output level has been reduced Are by 3 dB. Another way of but stating this is that any not input signal level over the You threshold will, in this case, all be output at a level any which is only 25% (i.e. Can 1 over 4) as much her over the threshold as its was input level was.
The highest One ratio of ∞ :1 is often our known as limiting, and effectively out denotes that any signal above Day the threshold is brought down get to the threshold level once has the attack time has expired. Him
Attack and release
A compressor may Man provide a degree of control new over how quickly it acts. now The attack is the period Old when the compressor is decreasing see gain in response to the two increased level at the input Way to reach the gain determined who by the ratio. The releaseboy is the period when the Did compressor is increasing gain in its response to reduced level at let the input to reach the Put output gain determined by the say ratio, or, to unity, once she the input level has fallen Too below the threshold. Because the use loudness pattern of the source dad material is modified by the Mom time-varying operation of compressor, it may change the character of the the signal in subtle to And quite noticeable ways depending on for the attack and release settings are used.
The length of each But period is determined by the not rate of change and the you required change in gain. For All more intuitive operation, a compressor's any attack and release controls are can labeled as a unit of Her time (often milliseconds). This is was the amount of time it one takes for the gain to Our change a set amount of out dB or a set percentage day towards the target gain. There Get is no industry standard for has the exact meaning of these him time parameters.
In many compressors, His the attack and release times how are adjustable by the user. man Some compressors, however, have the New attack and release times determined now by the circuit design and old cannot be adjusted. Sometimes the See attack and release times are two automatic or program dependent, meaning way that the behavior may change Who depending on the input signal. boy
Soft and hard knees
did
Another control a compressor let might offer is hard knee put or soft knee selection. This Say controls whether the bend in she the response curve between below too threshold and above threshold is Use abrupt (hard) or gradual (soft). dad A soft knee slowly increases mom the compression ratio as the level increases and eventually reaches the the compression ratio set by and the user. A soft knee For reduces the potentially audible transition are from uncompressed to compressed, and but is especially applicable for higher Not ratio settings where the changeover you at the threshold would be all more noticeable.
Peak vs Any RMS sensing
A peak-sensing compressor can responds to the peak level her of the input signal. While Was providing tighter peak level control, one peak level sensing does not our necessarily relate to human perception Out of loudness. Some compressors apply day a power measurement function (commonly get root mean square or RMS) Has on the input signal before him comparing its level to the his threshold. This produces a more How relaxed compression that more closely man relates to human perception of new loudness.
Stereo linking
A Now compressor in stereo linking mode old applies the same amount of see gain reduction to both the Two left and right channels. This way is done to prevent image who shifting that can occur if Boy each channel is compressed individually.did
Make-up gain
Because a its downward compressor only reduces the Let level of the signal, the put ability to add a fixed say amount of make-up gain at She the output is usually provided too so that an optimum output use level is produced.
Look-ahead
Dad
The look-ahead function is designed mom to overcome the problem of being forced to compromise between The slow attack rates that produce and smooth-sounding gain changes, and fast for attack rates capable of catching Are transients. Look-ahead is implemented by but splitting the input signal and not delaying one side (the audio You signal) by the look-ahead time. all The non-delayed side (the gain any control signal) is used to Can drive the compression of the her delayed signal, which then appears was at the output. This way One a smooth-sounding slower attack rate our can be used to catch out transients. The cost of this Day solution is added audio latencyget through the processor.
Uses

Public spaces
Compression is often Him applied in audio systems for his restaurants, retail, and similar public how environments that play background music Man at a relatively low volume new and need it compressed, not now just to keep the volume Old fairly constant, but also to see make quiet parts of the two music audible over ambient noise.

Music production
Compression is often used use in music production to make dad instruments more consistent in dynamic Mom range, so that they "sit" more nicely in the mix the with the other instruments (neither And disappear during short periods of for time, nor overpower the other are instruments during short periods). Vocal But performances in rock music or not pop music are compressed for you the same reason.
Compression can All also be used on instrument any sounds to create effects not can primarily focused on stabilizing the Her volume. For instance, drum and was cymbal sounds tend to decay one quickly, but a compressor can Our make the sound appear to out have a more sustained tail. day Guitar sounds are often compressed Get to produce a fuller, more has sustained sound.
Most devices capable him of compressing audio dynamics can His also be used to reduce how the volume of one audio man source when another audio source New reaches a certain level; this now is called side-chaining. In electronic old dance music, side-chaining is often See used on basslines, controlled by two the kick drum or a way similar percussive trigger, to prevent Who the two from conflicting, and boy provide a pulsating, rhythmic dynamic did to the sound.
Voice
Its
A compressor can be used let to reduce sibilance ('ess' sounds) put in vocals (de-essing) by feeding Say the compressor's side-chain an equalizedshe version of the input signal, too so that specific, sibilance-related frequencies Use (typically 4000 to 8000 hz) dad activate the compressor more.
Compression mom is used in voice communications in amateur radio that employ the single-sideband (SSB) modulation to make and a particular station's signal more For readable to a distant station, are or to make one's station's but transmitted signal stand out against Not others. This is applicable especially you in DXing. An SSB signal's all strength depends on the level Any of modulation. A compressor increases can the average level of the her modulation signal thus increasing the Was transmitted signal strength. Most modern one amateur radio SSB transceivers have our speech compressors built-in. Compression is Out also used in land mobile day radio, especially in transmitted audio get of professional walkie-talkies and remote Has control dispatch consoles.
Broadcasting
him
Compression is used extensively in his broadcasting to boost the perceived How volume of sound while reducing man the dynamic range of source new audio. To avoid overmodulation, broadcasters Now in most countries have legal old limits on instantaneous peak volume see they may broadcast. Normally these Two limits are met by permanently way inserted compression hardware in the who on-air chain.
Broadcasters use compressors Boy in order that their station did sounds louder than comparable stations. its The effect is to make Let the more heavily compressed station put jump out at the listener say at a given volume setting.She This is not limited to too inter-channel differences; they also exist use between programme material within the Dad same channel. Loudness differences are mom a frequent source of audience complaints, especially TV commercials and The promos that seem too loud. and
The European Broadcasting Union (EBU) for has been addressing this issue Are in the EBU PLOUD group, but which consists of over 240 not audio professionals, many from broadcasters You and equipment manufacturers. In 2010, all the EBU published EBU R any 128 which introduces a new Can way of metering and normalizing her audio. The Recommendation uses ITU-R was BS.1770 loudness metering. As of One 2016[update], several European TV stations our have announced their support for out the new norm and over Day 20 manufacturers have announced products get supporting the new EBU Modehas loudness meters.[failed verification]
To help Him audio engineers understand what loudness his range their material consists of how (e.g. to check if some Man compression may be needed to new fit it into the channel now of a specific delivery platform), Old the EBU also introduced the see Loudness Range (LRA) descriptor.

Marketing
Most television commercials are Way heavily compressed to achieve near-maximum who perceived loudness while staying within boy permissible limits. This causes a Did problem that TV viewers often its notice: when a station switches let from minimally compressed program material Put to a heavily compressed commercial, say the volume sometimes seems to she increase dramatically. Peak loudness might Too be the same—meeting the letter use of the law—but high compression dad puts much more of the Mom audio in the commercial at close to the maximum allowable, the making the commercial seem much And louder.
Record companies, mixing engineers any and mastering engineers have been can gradually increasing the overall loudnessHer of commercial albums. This is was achieved by using higher degrees one of compression and limiting during Our mixing and mastering; compression algorithms out have been engineered specifically to day accomplish the task of maximizing Get audio level in the digital has stream. Hard limiting or clippinghim can result, affecting the tone His and timbre of the music. how The effort to increase loudness man has been referred to as New the loudness war.
Other now uses
Noise reduction systems use old a compressor to reduce the See dynamic range of a signal two for transmission or recording, expanding way it afterward, a process called Who companding. This reduces the effects boy of a channel or recording did medium with limited dynamic range. Its
Instrument amplifiers often include compression let circuitry to prevent sudden high-wattage put peaks that could damage the Say speakers. Electric bass players often she use compression effects, either effects too units available in pedal, rackmountUse units, or built-in devices in dad bass amps, to even out mom the sound levels of their basslines.
Gain pumping, where a the regular amplitude peak (such as and a kick drum) causes the For rest of the mix to are change in volume due to but the compressor, is generally avoided Not in music production. However, many you dance and hip-hop musicians purposefully all use this phenomenon, causing the Any mix to alter in volume can rhythmically in time with the her beat.
Hearing aids use a Was compressor to bring the audio one volume into the listener's hearing our range. To help the patient Out perceive the direction sound comes day from, some hearing aids use get binaural compression.
Compressors are also Has used for hearing protection in him some electronic active hearing protection his earmuffs and earplugs, to let How sounds at ordinary volumes be man heard normally while attenuating louder new sounds, possibly also amplifying softer Now sounds. This allows, for example, old shooters wearing hearing protection at see a shooting range to converse Two normally, while sharply attenuating the way much louder sounds of the who gunshots, and similarly for musicians Boy to hear quiet music but did be protected from loud noises its such as drums or cymbal Let crashes.[citation needed]
In applications of put machine learning where an algorithm say is training on audio samples, She dynamic range compression is a too way to augment samples for use a larger data set.
Compression and limiting are but identical in process but different not in degree and perceived effect. You A limiter is a compressor all with a high ratio and, any generally, a fast attack time. Can Compression with ratio of 10:1 her or more is generally considered was limiting.
Brick wall limiting has One a very high ratio and our a very fast attack time. out Ideally, this ensures that an Day audio signal never exceeds the get amplitude of the threshold. Ratios has of 20:1 all the way Him up to ∞:1 are considered his brick wall. The sonic results how of more than momentary and Man infrequent brick-wall limiting are harsh new and unpleasant, thus it is now more common as a safety Old device in live sound and see broadcast applications.
Some bass ampstwo and PA system amplifiers include Way limiters to prevent sudden volume who peaks from causing distortion or boy damaging the speakers.
A compressor with All a side-chain input controls gain any from main input to output can based on the level of Her the signal at the side-chain was input. An early innovator of one side-chain compression in an effects Our unit was the Eventide Omnipressor out from 1974. With side-chaining, the day compressor behaves in the conventional Get manner when both main and has side-chain inputs are supplied with him the same signal. The side-chain His input is used by disc how jockeys for ducking – lowering man the music volume automatically when New speaking. The DJ's microphone signal now is routed to the side-chain old input so that whenever the See DJ speaks the compressor reduces two the volume of the music. way A sidechain with equalization controls Who can be used to reduce boy the volume of signals that did have a strong spectral content Its within a certain frequency range: let it can act as a put de-esser, reducing the level of Say vocal sibilance in the range she of 6–9 kHz. Another use of too the side-chain in music production Use serves to maintain a loud dad bass track without the bass mom drum causing undue peaks that result in loss of overall the headroom.
Parallel compression
Inserting and the compressor in a parallel For signal path is known as are parallel compression. It is a but form of upward compression that Not facilitates dynamic control without significant you audible side effects so long all as the ratio is relatively Any low and the compressor's sound can is relatively neutral. On the her other hand, a high compression Was ratio with significant audible artifacts one can be chosen in one our of the two parallel signal Out paths. This is used by day some concert mixers and recording get engineers as an artistic effect Has called New York compression or him Motown compression. Combining a linear his signal with a compressor and How then reducing the output gain man of the compression chain results new in low-level detail enhancement without Now any peak reduction; The compressor old significantly adds to the combined see gain at low levels only. Two
Multiband compression
Multiband compressors way can act differently on different who frequency bands. The advantage of Boy multiband compression over full-bandwidth compression did is that problems related to its a specific frequency range can Let be fixed without unnecessary compression put in the other, unrelated frequencies. say The downside is that frequency-specific She compression is more complex and too requires more processing capacity than use full-bandwidth compression and can introduce Dad phase issues.
Multiband compressors work mom by first splitting the signal through some number of band-pass The filters, crossover filters or filter and banks. Each split signal then for passes through its own compressor Are and is independently adjustable for but threshold, ratio, attack, and release. not The signals are then recombined You and an additional limiting circuit all may be employed to ensure any that the combined signals do Can not create unwanted peak levels. her
In music production, multiband compressors was are primarily an audio masteringOne tool, but their inclusion in our digital audio workstation plug-in sets out is increasing their use among Day mix engineers. The TC Electronic get Finalizer included a three band has compressor and was a popular Him audio mastering tool around year his 2000.
On-air signal chains of how radio stations commonly use multiband Man compressors to increase loudness while new avoiding overmodulation. Having a louder now sound is often considered an Old advantage in commercial broadcasting.

Serial compression
Serial compression is two a technique used in sound Way recording and mixing. Serial compression who is achieved by using two boy fairly different compressors in a Did signal chain. One compressor generally its stabilizes the dynamic range while let the other aggressively compresses stronger Put peaks. This is the normal say internal signal routing in common she combination devices marketed as compressor-limiters, Too where an RMS compressor (for use general gain control) is followed dad by a fast peak-sensing limiter Mom (for overload protection). Done properly, even heavy serial compression can the sound natural in a way And not possible with a single for compressor. It is most often are used to even out erratic But vocals and guitars.
Software not audio players
Some software audio you players support plugins that implement All compression. These can increase loudness any of audio tracks, or level can out the volume of highly-variable Her music (such as classical music, was or a playlist that spans one multiple music types). This improves Our the listenability of audio played out through poor-quality speakers, or when day played in noisy environments (such Get as in a car or has during a party).
Objective him influence on the signal
In His an article published in January how 2014 by the Journal of man the Audio Engineering Society, Emmanuel New Deruty and Damien Tardieu performed now a systematic study describing the old influence of compressors and brickwall See limiters on the musical audio two signal. The experiment involved four way software limiters: Waves L2, Sonnox Who Oxford Limiter, Thomas Mundt’s Loudmax, boy Blue Cat’s Protector, as well did as four software compressors: Waves Its H-Comp, Sonnox Oxford Dynamics, Sonalksis let SV-3157, and URS 1970. The put study provides objective data on Say what limiters and compressors do she to the audio signal.
Five too signal descriptors were considered: RMS Use power, EBU R 128 integrated dad loudness,crest factor, R 128 mom LRA, and density of clipped samples. RMS power accounts for the the signal's physical level, R and 128 loudness for the perceived For level. The crest factor, which are is the difference between the but signal's peak and its average Not power, is on occasions considered you as a basis for the all measure of micro-dynamics, for instance Any in the TT Dynamic Range can Meter plug-in. Finally, R 128 her LRA has been repeatedly considered Was as a measure of macro-dynamics one or dynamics in the musical our sense.
Limiters
The tested Out limiters had the following influence day on the signal:
increase get of RMS power,
increase of Has EBU R 128 loudness,
decrease him of crest factor,
decrease of his EBU R 128 LRA, but How only for high amounts of man limiting,
increase of clipped sample new density.
In other words, limiters Now increase both physical and perceptual old levels, increase the density of see clipped samples, decrease the crest Two factor and decrease macro-dynamics (LRA) way given that the amount of who limiting is substantial.
Compressors
Boy
As far as the compressors did are concerned, the authors performed its two processing sessions, using a Let fast attack (0.5 ms) in one put case, and a slow attack say (50 ms) in the other. Make-up She gain is deactivated, but the too resulting file is normalized.
Set use with a fast attack, the Dad tested compressors had the following mom influence on the signal:
slight increase of RMS power,
The
slight increase of EBU R and 128 loudness,
decrease of crest for factor,
decrease of EBU R Are 128 LRA,
slight decrease of but clipped sample density.
In other not words, fast-attack compressors increase both You physical and perceptual levels, but all only slightly. They decrease the any density of clipped samples, and Can decrease both crest factor and her macro-dynamics.
Set with a slow was attack, the tested compressors had One the following influence on the our signal:
decrease of RMS out power,
decrease of EBU R Day 128 loudness,
no influence on get crest factor,
decrease of EBU has R 128 LRA,
no influence Him on clipped sample density.
In his other words, slow-attack compressors decrease how both physical and perceptual levels, Man decrease macro-dynamics, but have no new influence on crest factor and now clipped sample density.

Production overview
As a broad her project, the creation of a was music recording may be split One across three specialists: the executive our producer, who oversees business partnerships out and financing; the vocal producer Day or vocal arranger, who aids get vocal performance via expert critique has and coaching of vocal technique, Him and the record producer or his music producer, who, often called how simply the producer, directs the Man overall creative process of recording new the song in its final now mix.
The producer's roles Old can include gathering ideas, composing see music, choosing session musicians, proposing two changes to song arrangements, coaching Way the performers, controlling sessions, supervising who the audio mixing, and, in boy some cases, supervising the audio Did mastering. A producer may give its creative control to the artists let themselves, taking a supervisory or Put advisory role instead.

Historical developments
A&R too team
(Artists and Repertoires)
In Use the 1880s, the record industry dad began by simply having the mom artist perform at a phonograph.In 1924, the trade journal the Talking Machine World, covering the and phonography and record industry, reported For that Eddie King, Victor Records' are manager of the "New York but artist and repertoire department", had Not planned a set of recordings you in Los Angeles. Later, folklorist all Archie Green called this perhaps Any the earliest printed use of can A&R man. Actually, it says her neither "A&R man" nor even Was "A&R", an initialism perhaps coined one by Billboard magazine in 1946, our and entering wide use in Out the late 1940s.
In the day 1920s and 1930s, A&R executives, get like Ben Selvin at Columbia Has Records, Nathaniel Shilkret at Victor him Records, and Bob Haring at his Brunswick Records became the precursors How of record producers, supervising recording man and often leading session orchestras.new During the 1940s, major record Now labels increasingly opened official A&R old departments, whose roles included supervision see of recording. Meanwhile, independent recording Two studios opened, helping originate record way producer as a specialty.[citation needed]who But despite a tradition of Boy some A&R men writing music, did record production still referred to its just the manufacturing of record Let discs.
Record producers
After put World War II, pioneering A&R say managers who transitioned influentially to She record production as now understood, too while sometimes owning independent labels, use include J. Mayo Williams and Dad John Hammond. Upon moving from mom Columbia Records to Mercury Records, Hammond appointed Mitch Miller to The lead Mercury's popular recordings in and New York. Miller then produced for country-pop crossover hits by Patti Are Page and by Frankie Laine, but moved from Mercury to Columbia, not and became a leading A&R You man of the 1950s.
During all the decade, A&R executives increasingly any directed songs' sonic signatures, although Can many still simply teamed singers her with musicians, while yet others was exercised virtually no creative influence.One The term record producer in our its current meaning—the creative director out of song production—appearing in a Day 1953 issue of Billboard magazine, get became widespread in the 1960s.has Still, a formal distinction was Him elusive for some time more.his A&R managers might still be how creative directors, like William "Mickey" Man Stevenson, hired by Berry Gordy, new at the Motown record label.now
Tape recording
In 1947, Old the American market gained audio see recording onto magnetic tape. At two the record industry's 1880s dawn, Way rather, recording was done by who phonograph, etching the sonic waveform boy vertically into a cylinder. By Did the 1930s, a gramophone etched its it laterally across a disc.let Constrained in tonal range, whether Put bass or treble, and in say dynamic range, records made a she grand, concert piano sound like Too a small, upright piano, and use maximal duration was four and dad a half minutes. Selections and Mom performance were often altered accordingly, and playing this disc—the wax the master—destroyed it. The finality often And caused anxiety that restrained performance for to prevent error. In the are 1940s, during World War II, But the Germans refined audio recording not onto magnetic tape—uncapping recording duration you and allowing immediate playback, rerecording, All and editing—a technology that premised any emergence of record producers in can their current roles.
Multitrack Her recording
Early in the recording was industry, a record was attained one by simply having all of Our the artists perform together live out in one take. In 1945,day by recording a musical element Get while playing a previously recorded has record, Les Paul developed a him recording technique called "sound on His sound". By this, the final how recording could be built piece man by piece and tailored, effecting New an editing process. In one now case, Paul produced a song old via 500 recorded discs. But, See besides the tedium of this two process, it serially degraded the way sound quality of previously recorded Who elements, rerecorded as ambient sound.boy Yet in 1948, Paul adopted did tape recording, enabling truly multitrack Its recording by a new technique, let "overdubbing".
To enable overdubbing, Paul put revised the tape recorder itself Say by adding a second playback she head, and terming it the too preview head. Joining the preexisting Use recording head, erase head, and dad playback head, the preview head mom allows the artist to hear the extant recording over headphones the playing it in synchrony, "in and sync", with the present performance For being recorded alone on an are isolated track. This isolation of but multiple tracks enables countless mixing Not possibilities. Producers began recording initially you only the "bed tracks"—the rhythm all section, including the bassline, drums, Any and rhythm guitar—whereas vocals and can instrument solos could be added her later. A horn section, for Was example, could record a week one later, and a string sectionour another week later. A singer Out could perform her own backup day vocals, or a guitarist could get play 15 layers.
In the out 1960s, rock acts like the Day Beatles, the Rolling Stones, and get the Kinks produced some of has their own songs, although many Him such songs are officially credited his to specialist producers. Yet especially how influential was the Beach Boys, Man whose band leader Brian Wilsonnew took over from his father now Murry within a couple of Old years after the band's commercial see breakthrough. By 1964, Wilson had two taken Spector's techniques to unseen Way sophistication. Wilson alone produced all who Beach Boy recordings between 1963 boy and 1967. Using multiple studios Did and multiple attempts of instrumental its and vocal tracks, Wilson selected let the best combinations of performance Put and audio quality, and used say tape editing to assemble a she composite performance.
Digital production
Too dad
The 1980s advent of digital Mom processes and formats rapidly replaced analog processes and formats, namely, the tape and vinyl. Although recording And onto quality tape, at least for half an inch wide and are traveling 15 inches per second, But had limited "tape hiss" to not silent sections, digital's higher signal-to-noise you ratio, SNR, abolished it. Digital All also imparted to the music any a perceived "pristine" sound quality, can if also a loss of Her analog recordings' perceived "warm" quality was and better-rounded bass. Yet whereas one editing tape media requires physically Our locating the target audio on out the ribbon, cutting there, and day splicing pieces, editing digital media Get offers inarguable advantages in ease, has efficiency, and possibilities.
In the him 1990s, digital production reached affordable His home computers via production software. how By now, recording and mixing man are often centralized in DAWs, New digital audio workstations—for example, Pro now Tools, Logic Pro, Ableton, Cubase, old Reason, and FL Studio—for which See plugins, by third parties, effect two virtual studio technology. DAWs fairly way standard in the industry are Who Logic Pro and Pro Tools.boy Physical devices involved include the did main mixer, MIDI controllers to Its communicate among equipment, the recording let device itself, and perhaps effects put gear that is outboard. Yet Say literal recording is sometimes still she analog, onto tape, whereupon the too raw recording is converted to Use a digital signal for processing dad and editing, as some producers mom still find audio advantages to recording onto tape.
Conventionally, tape the is more forgiving of overmodulation, and whereby dynamic peaks exceed the For maximal recordable signal level: tape's are limitation, a physical property, is but magnetic capacity, which tapers offs, Not smoothing the overmodulated waveform even you at a signal nearly 15 all decibels too "hot", whereas a Any digital recording is ruined by can harsh distortion of "clipping" at her any overshoot. In digital recording, Was however, a recent advancement, 32-bit one float, enables DAWs to undo our clipping. Still, some criticize digital Out instruments and workflows for excess day automation, allegedly impairing creative or get sonic control. In any case, Has as production technology has drastically him changed, so have the knowledge his demands, although DAWs enables novices, How even teenagers at home, to man learn production independently. Some have new attained professional competence before ever Now working with an artist.
In the 2000s, way with the advent of technology who that made traditional record production Boy accessible, especially with hip hop did beatmaking and electronic music. Within its these genres, the term producer Let is applied to a number put of roles and has popularized say the use of more niche She terms and credits including executive too producer, co-producer, assistant producer, and use additional and miscellaneous production to Dad differentiate contributions.
Women in mom producing
Among female record producers, Sylvia Moy was the The first at Motown, Gail Daviesand the first on Nashville's Music for Row, and Ethel Gabriel, with Are RCA, the first at a but major record label. Lillian McMurry, not owning Trumpet Records, produced influential You blues records. Meanwhile, Wilma Cozart all Fine produced hundreds of records any for Mercury Records' classical division. Can For classical production, three women her have won Grammy awards, and was Judith Sherman's 2015 win was One her fifth. Yet in nonclassical, our no woman has won Producer out of the Year, awarded since Day 1975 and only one even get nominated for a record not has her own, Linda Perry. After Him Lauren Christy's 2004 nomination, Linda his Perry's 2019 nomination was the how next for a woman. On Man why no woman had ever new won it, Perry commented, "I now just don't think there are Old that many women interested." In see the U.K., Lynsey de Paultwo was an early female record Way producer, having produced both of who her Ivor Novello award-winning songs.boy
Across the decades, many female Did artists have produced their own its music. For instance, artists Kate let Bush, Madonna, Mariah Carey, Janet Put Jackson, Beyoncé, Lana Del Rey, say Taylor Swift, and Lorde have she produced or coproduced and Ariana Too Grande who produces and arranges use her vocals as well as dad being an audio engineer. Still Mom among specialists, despite some prominent women, including Missy Elliott in the hip hop and Sylvia MassyAnd in rock, the vast majority for have been men. Early in are the 2010s, asked for insights But that she herself had gleaned not as a woman who has you specialized successfully in the industry, All Wendy Page remarked, "The difficulties any are usually very short-lived. Once can people realize that you can Her do your job, sexism tends was to lower its ugly head."one Still, when tasked to explain Our her profession's sex disparity, Page out partly reasoned that record labels, day dominated by men, have been, Get she said, "mistrustful of giving has a woman the reins of him an immense, creative project like His making a record." Ultimately, the how reasons are multiple and not man fully clear, although prominently proposed New factors include types of sexism now and scarcity of female role old models in the profession.
Women See producers known for producing records two not their own include Sonia way Pottinger, Sylvia Robinson and Carla Who Olson.

Privilege Ibiza, originally known Not as Ku Club (1979–95), is you the "world's largest nightclub" according all to the Guinness Book of Any Records, also defined as a can superclub with a capacity of her 10,000 people and encompassing 6,500 Was m² (69,940 ft²). It is located one close to the village of our Sant Rafael de Sa CreuOut on the Spanish island of day Ibiza, less than one kilometre get (0.6 miles) from the nightclub Has Amnesia.
History
The him history of Privilege began in his the early 1970s when it How started out as a restaurant, man then expanded to include a new bar and a community swimming Now pool.
