Uma ungumdlali wesiginci ofuna izindlela ezintsha ezithokozisayo zokuthuthukisa ukudlala kwakho isiginci, maningi amathuba okuthi uthole igama elithi “compression umphumela. "
Akumangazi ukuthi ingenye yezindlela ezingaqondakali kakhulu futhi mhlawumbe eziyinkimbinkimbi kakhulu ukuze ube yingcweti njengomdlali wesigingci.
Kodwa hey, kuyafaneleka uma usuthole i-hang of it!
Umphumela wokucindezela ukusiza ukuthi ugcine amandla esignali akho elawula ngokwehlisa imisindo ephezulu ngaphezu komkhawulo othile futhi ukhuphule ephansi engaphansi kwawo. Imingcele yokucindezela ingasethwa phakathi noma ngemva kokusebenza (emva kokukhiqizwa) ngesofthiwe ezinikele nehadiwe.
Lesi sihloko sizohlanganisa zonke izisekelo odinga ukuzazi mayelana nalo mphumela wemilingo ukuze uqalise.
Uyini umphumela wokucindezela?
Uma usengumdlali wekamelo lokulala, kuyaqondakala ukuthi kungani ubungeke wazi okuningi mayelana nokubaluleka komphumela wokucindezelwa noma umphumela ngokwawo; ayidingeki lapho.
Kodwa-ke, uzoqaphela okuthile njengoba ushiya ukunethezeka kwegumbi lakho futhi uthuthela kuzilungiselelo ezichwepheshile nezobuchwepheshe njengesikhala sestudiyo noma isiteji esibukhoma:
Izingxenye ezithambile zihlala zincibilika emoyeni, kuyilapho ezidlulayo zihlala zigqamile.
Ama-Transients ayiziqongo zokuqala zomsindo lapho sishaya intambo, futhi izingxenye ezithambile yizona ezingaphumi ngendlela echazwe ngayo ngenxa yomsindo wezinto ezidlulayo.
Isizathu sokuthi sisebenzisa ama-compressor ukulawula lezi zindlela ezidlulayo futhi ziphume nawo wonke umsindo.
Nakuba ungabhekana nalokhu uwedwa uma unezinga elithile le-finesse, kusenzima ngisho nokwehlisa wonke amathoni ngenxa yesimo se-tonal isiginci sikagesi.
Lokhu kubaluleke kakhulu uma usebenzisa isiginci esihlanzekile, ngaphandle kokusebenzisa noma yimiphi imiphumela efana nokuhlanekezela (okuphusha i-amp idlule imikhawulo yayo), kanye nokuhlanekezela (okungewona umsindo ohlanzekile).
Ukuze uthole umsindo ongaguquki, ngisho neziginci ezingomakadebona zisebenzisa umphumela wokucindezela.
Kuyindlela esiza ekulawuleni ivolomu lapho isignali yokufaka inomsindo omkhulu kuneleveli emisiwe (okwaziwa ngokuthi ukuminyanisa okuya phansi) noma iyibuyisele emuva uma iphansi (okwaziwa ngokuthi ukucindezela ukuya phezulu).
Ngokusebenzisa lo mphumela, ububanzi obuguquguqukayo besiginci bulinganiswa; ngakho, imisindo ewumphumela iba bushelelezi, inothi ngalinye liyakhanya futhi liqashelwe kuso sonke isikhathi sokudlala ngaphandle kokuhlephula ivolumu ngokungadingekile.
Umphumela usetshenziswa abaculi abavela ezinhlotsheni ezahlukahlukene, ezinomculo oluhlaza okwesibhakabhaka nowezwe phezulu.
Lokhu kungenxa yokuthi umehluko oguqukayo phakathi kwamanothi omculo onjalo mkhulu njengoba isiginci sidlalwa kakhulu ngendlela yokucosha iminwe.
Umphumela wokucindezelwa utholakala ngedivayisi eyaziwa ngokuthi i-compressor pedal. Kuyi-stompbox ehlala kuchungechunge lwakho lwesignali.
Ngandlela thize, kufana neknobhu yomsindo ezenzakalelayo egcina izinto ngaphakathi komkhawulo omisiwe, kungakhathaliseki ukuthi uyishaya kanzima kangakanani iyunithi yezinhlamvu.
Ukucindezela kuguqula amasu akho okudlala isiginci amahle vele abe yinto emangalisayo kuyilapho kwenze nabashayi besiginci abesabekayo bazwakale benesizotha.
Kodwa hey, ngingancoma ukuthi ufunde ithuluzi kuqala bese ugcwalisa imininingwane nge-compressor.
Ithuluzi lifanelwe le nhlonipho engaka, okungenani!
Amagama okucindezela okudingeka ukwazi
Uma ucabanga ngokuthola i-compressor, nanka amanye amagama ayisisekelo okudingeka ukwazi njengoba uqala:
I-Threshold
Leli yiphuzu elingenhla noma elingezansi lapho umphumela wokucindezela uzosebenza khona.
Ngakho-ke, njengoba ngike ngasho ngaphambili, noma iyiphi isignali yomsindo enomsindo kakhulu kunaleyo izokwehliswa, kuyilapho eziphansi zizokhushulwa (uma usebenzisa ukucindezelwa phezulu) noma zihlale zingathinteki.
lokubiza
Leli inani lokucindezelwa elisetshenziswa kumasiginali aphula umkhawulo. Uma isilinganiso siphezulu, ikhono le-compressor lokwehlisa umsindo liyoba likhulu.
Isibonelo, uma i-compressor inesilinganiso esingu-6:1, izoqala ukusebenza lapho umsindo ungu-6db ngaphezu kombundu, wehlisa umsindo, ngakho-ke uba ngu-1db kuphela ngaphezu kombundu.
Kukhona amanye amadivaysi afanayo afana nezikhawuli ezilula ezinesilinganiso esingu-10:1 kanye “nezikhawuli zodonga lwezitini” ezinesilinganiso esingu-∞:1.
Nokho, asetshenziswa uma ububanzi obuguquguqukayo buphezulu kakhulu. Ukuze uthole insimbi elula efana nesiginci, i-compressor elula isebenza ngokuphelele.
Attack
Isikhathi sokusabela se-compressor ngemva kokuba isignali yokufaka ifinyelele kuyo noma isikhathi esithathwe umminyanisi ukusetha ukuncipha ngemva kokuba isignali idlulele ngaphezu komkhawulo.
Ungasetha isikhathi sokuhlasela ngokushesha noma siphansi njengokuncamela kwakho. Isikhathi sokuhlasela okusheshayo silungile uma usuyisiginci esinekhono.
Kuzokusiza ukuthi ulawule lezo ziqongo ezingalawuleki kalula futhi kukusize wenze ukusebenza kwakho kuphucuzeke kakhudlwana.
Ngokuqondene nalabo abathanda isiginci sabo ukuthi sizwakale sinolaka, ukubeka isikhathi sokuhlasela kancane kuzosiza.
Nokho, akufanele isetshenziselwe imisindo enamandla kakhulu. Ngethembe; kwenza izinto zibe zimbi kakhulu kunalokho eseziyikho kakade.
release
Isikhathi esithathwa yi-compressor ukubuyisela isignali ezingeni layo ngaphambi kokucindezelwa.
Ngamanye amazwi, yisikhathi esithathwayo ukumisa ukuncishiswa komsindo uma wehla ngaphansi kwezinga lomkhawulo.
Nakuba inhlanganisela yokuhlasela okusheshayo nokukhululwa kuvame ukuthandwa, ukukhululwa kancane kuhle ekugcineni ukucindezelwa kucace futhi kukhanye futhi kusebenza kahle kakhulu ngemisindo enokusekela isikhathi eside, njengaleyo ye-bass. iziginci.
Inzuzo yokwenza imali
Njengoba i-compressor icindezela isignali, kufanele ibuyiselwe ezingeni layo langempela.
Ukulungiselelwa kwenzuzo yezimonyo kukuvumela ukuthi ukhuphule okukhiphayo futhi ulinganisele ukuncishiswa kwenzuzo okwenzeke ngesikhathi sokucindezelwa.
Noma uzokuthola lokhu kulungiselelwa ku-pedal yakho, uma ungakwenzi, mhlawumbe i-compressor yakho ikwenzela umsebenzi ngokuzenzakalelayo.
Nakhu uwamisa kanjani amaphedali omphumela wesiginci futhi wenze i-pedalboard ephelele
Yiziphi izinhlobo ezahlukene zokucindezelwa?
Nakuba kunezinhlobo eziningi zokucindezelwa, lezi ezintathu ezilandelayo yizona ezivame kakhulu:
Ukucindezelwa kwe-Optical
Ukucindezela kwe-Optical kusebenzisa izinto ezimelana nokukhanya ukuze kulingane amasignali.
Yaziwa ngokukhipha kwayo okubushelelezi futhi okusobala kuyilapho ithethelela kakhulu ngokuhlaselwa okunensayo nezilungiselelo zokukhulula.
Noma kunjalo, akusho ukuthi kubi ngezilungiselelo ezisheshayo.
Ukucindezelwa kwe-Optical kwaziwa ngokungeza "bloom" ethile kumanothi ngenkathi futhi wengeza ibhalansi ethile kuma-chords, okunikeza isiginci umsindo ocolisisiwe.
Ukucindezelwa kwe-FET
Ukucindezelwa kwe-FET kulawulwa yi-Field Effect Transistor. Ingenye yezinhlobo zokuminyanisa ezisetshenziswa kakhulu kuzilungiselelo zesitudiyo.
Kuyaziwa ngokungeza leyo signesha ethi "smack" emsindweni ohambisana nazo zonke izitayela zokudlala nohlobo.
Ngezilungiselelo ezilungile, kuhle kakhulu.
Ukucindezela kwe-VCA
I-VCA imele i-Voltage Controlled Amplifier, futhi “iwuhlobo” oluguquguqukayo kakhulu nolujwayelekile olusetshenziswa abaculi.
Ama-compressor anjalo asebenza ngendlela elula yokuguqula amasiginali wesiginci se-AC abe yi-DC voltage, etshela i-VCA ukuthi ikhuphuke noma yehle.
Ngokuqondene nokusebenza kwayo, izokusebenzela nobabili njengokucindezelwa kwe-FET nokucindezelwa kokubona.
Uma usuyitholile i-hang yayo, uzoyithanda!
Ingabe kufanele usebenzise ukucindezela?
Ukucindezela kuyingxenye ebalulekile yomculo wesimanje.
Alikho neculo elingawusebenzisi umsindo, ngisho nalawo anabashaya isiginci abanekhono kakhulu esitudiyo.
Ukusebenzisa umthelela ngokuhlakanipha nangobuciko kungashintsha ngisho nomculo osobala ube into emnandi ezindlebeni.
Lo mhlahlandlela ubumayelana nokukunikeza ukuqonda okuyisisekelo komphumela kanye nezindaba okufanele uzazi njengoba uqala.
Noma kunjalo, ukwenza kahle umphumela akuqondile njengoba kuzwakala, futhi uzodinga isilinganiso esifanele sokuzijwayeza ukuze uyisebenzise ngokuphelele.
Sesikushilo lokho, manje okudingeka ukwenze nje ukuthenga idivayisi ye-compressor enhle kakhulu futhi wenze ukusetha kwakho kwenziwe ngendlela esichaze ngayo kulesi sihloko.
NginguJoost Nusselder, umsunguli we-Neaera kanye nomkhangisi wokuqukethwe, ubaba, futhi ngiyathanda ukuzama izinto ezintsha ngesiginci enhliziyweni yesifiso sami, futhi kanye nethimba lami, bengilokhu ngidala izindatshana zebhulogi ezijulile kusukela ngo-2020. ukusiza abafundi abathembekile ngokurekhoda namathiphu esiginci.
