Yog tias koj yog tus ntaus guitar tab tom nrhiav cov tswv yim tshiab los txhim kho koj qhov kev ua si guitar, muaj lub caij nyoog zoo koj tau hla lub sij hawm "compression nyhuv. "
Tsis xav tsis thoob, nws yog ib qho kev nkag siab tsis zoo tshaj plaws thiab tej zaum cov txheej txheem nyuaj tshaj plaws los ua tus ntaus guitar.
Tab sis hav, nws tsim nyog nws thaum koj tau txais lub hang ntawm nws!
Cov nyhuv compression pab koj kom koj lub teeb liab muaj zog hauv kev tswj hwm los ntawm kev txo qis lub suab nrov saum ib qho chaw pib thiab nce qib qis hauv qab nws. Cov compression tsis tuaj yeem teeb tsa thaum lub sijhawm lossis tom qab kev ua haujlwm (hauv kev tsim khoom tom qab) los ntawm kev mob siab rau software thiab kho vajtse.
Kab lus no yuav hais txog tag nrho cov hauv paus ntsiab lus uas koj xav paub txog cov txiaj ntsig zoo li no kom koj pib.
Cov nyhuv compression yog dab tsi?
Yog tias koj tseem yog chav pw, nws nkag siab tias vim li cas koj yuav tsis paub ntau txog qhov tseem ceeb ntawm cov nyhuv compression lossis txawm tias cov nyhuv nws tus kheej; nws tsis xav tau muaj.
Txawm li cas los xij, koj yuav pom ib yam dab tsi thaum koj tawm hauv koj chav tsev thiab txav mus rau ntau qhov kev tshaj lij thiab kev teeb tsa zoo li studio chaw lossis nyob theem:
Cov mos mos tas li yaj nyob rau hauv cov cua, thaum lub sij hawm ib ntus tseem conspicuous.
Transients yog thawj peaks nyob rau hauv lub suab thaum peb ntaus ib txoj hlua, thiab cov khoom mos yog cov tsis nrov, yog li lawv tsis tuaj raws li tau hais tseg vim lub nrov ntawm cov transients.
Yog vim li cas peb siv compressors yog los tswj cov kev hloov pauv no thiab txawm tias lawv tawm nrog lub suab tas li.
Txawm hais tias koj tuaj yeem cuam tshuam nrog qhov no ntawm koj tus kheej yog tias koj muaj qee theem ntawm finesse, nws tseem tsis tuaj yeem ua rau tag nrho cov tones vim yog tonal xwm ntawm ib qho. hluav taws xob guitar.
Qhov no yog qhov tshwj xeeb tshaj yog thaum siv lub guitar huv si, tsis tas siv cov teebmeem tshwj xeeb xws li distortion (uas thawb lub amp dhau nws cov kev txwv), thiab distortion (uas, zoo, tsis yog lub suab huv).
Txhawm rau kom tau txais lub suab zoo ib yam, txawm tias cov neeg ntaus suab paj nruag feem ntau siv cov nyhuv compression.
Nws yog ib qho txheej txheem uas pab tswj lub ntim thaum lub teeb liab tawm suab nrov dua li theem teeb tsa (lub npe hu ua downward compression) lossis tig rov qab thaum nws qis dua (paub tias upward compression).
Siv cov nyhuv no, lub guitar qhov dynamic ntau yog evened tawm; Yog li, cov suab nrov yog smoother, nrog rau txhua daim ntawv ci tawm thiab tau pom thoob plaws lub sijhawm ua si yam tsis tau tawg lub ntim tsis tsim nyog.
Cov nyhuv yog siv los ntawm cov kws ua yeeb yam los ntawm ntau hom, nrog rau kev nyuaj siab thiab lub teb chaws suab paj nruag nyob rau sab saum toj.
Tias yog vim li cas qhov sib txawv ntawm cov ntawv sau hauv cov suab paj nruag yog qhov loj heev vim tias lub guitar feem ntau ua si hauv fingerpicking style.
Cov nyhuv compression yog ua tiav los ntawm cov cuab yeej hu ua compressor pedal. Nws yog stompbox uas zaum hauv koj lub teeb liab saw.
Nyob rau hauv ib txoj kev, nws zoo li lub suab tsis siv neeg lub pob qhov rooj uas khaws cov khoom tsis pub dhau qhov txwv, txawm tias koj ntaus txoj hlua nyuaj npaum li cas.
Compression hloov koj cov txuj ci zoo nkauj guitar ua si rau hauv ib yam dab tsi zoo kawg nkaus thaum ua txawm tias cov guitarists txaus ntshai tshaj plaws suab zoo.
Tab sis hav, kuv xav kom mastering lub twj paj nruag ua ntej thiab tom qab ntawd sau cov ntsiab lus los ntawm compressor.
Qhov ntsuas tsim nyog qhov kev hwm no, tsawg kawg!
Cov ntsiab lus compression koj yuav tsum paub
Yog tias koj tab tom xav txog kev tau txais lub tshuab compressor, ntawm no yog qee cov ntsiab lus yooj yim tshaj plaws uas koj yuav tsum paub thaum koj pib:
Threshold
Qhov no yog lub ntsiab lus saum toj no lossis hauv qab uas cov nyhuv compression yuav los ua haujlwm.
Yog li, raws li kuv tau hais dhau los, txhua lub suab teeb liab uas nrov tshaj qhov yuav raug txo qis, thaum cov qis dua yuav raug upped (yog tias koj siv upward compression) lossis tseem tsis cuam tshuam.
piv
Qhov no yog tus nqi ntawm compression siv rau cov teeb liab tawg qhov pib. Qhov siab dua qhov sib piv, ntau lub compressor lub peev xwm los txo lub suab yuav.
Piv txwv li, yog tias lub compressor muaj qhov sib piv 6: 1, nws yuav tshwm sim thaum lub suab yog 6db saum toj ntawm qhov pib, tig lub suab, yog li nws tsuas yog 1db tshaj qhov pib.
Muaj lwm yam khoom siv zoo sib xws xws li cov txwv yooj yim nrog qhov piv ntawm 10: 1 thiab "cib phab ntsa limiters" nrog qhov piv ntawm ∞: 1.
Txawm li cas los xij, lawv siv thaum lub dynamic ntau yam siab dhau. Rau cov cuab yeej yooj yim xws li guitar, compressor yooj yim ua haujlwm zoo kawg nkaus.
Attack
Nws yog lub sij hawm cov tshuaj tiv thaiv ntawm lub compressor tom qab ib tug input teeb liab mus txog nws los yog lub sij hawm coj los ntawm lub compressor los teem lub attenuation tom qab lub teeb liab mus rau saum toj no qhov pib.
Koj tuaj yeem teem sijhawm tawm tsam sai lossis qis raws li koj nyiam. Lub sijhawm nrawm nrawm yog qhov zoo tagnrho yog tias koj twb yog tus kws tshaj lij guitarist.
Nws yuav pab koj tswj cov siab tsis ncaj no yooj yim heev thiab pab koj ua kom koj qhov kev ua tau zoo dua.

Txawm li cas los xij, nws tsis yog yuav tsum tau siv rau cov suab nrov super dynamic. Ntseeg kuv; nws ua rau tej yam txaus ntshai tshaj qhov lawv twb muaj lawm.
tso tawm
Nws yog lub sij hawm lub compressor siv coj lub teeb liab rov qab mus rau nws qib ua ntej compression.
Nyob rau hauv lwm yam lus, nws yog lub sij hawm coj mus tso tseg lub suab attenuation ib zaug nws poob qis dua theem pib.
Txawm hais tias kev sib xyaw ua ke ntawm kev tawm tsam sai thiab tso tawm feem ntau nyiam, qhov kev tso tawm qeeb qeeb yog qhov zoo hauv kev ua kom lub compression clearer thiab pob tshab thiab ua haujlwm zoo heev rau lub suab nrog ntev zog, zoo li cov ntses bass thaj tsam. cov guitars.
Pleev tau qhov nce
Raws li lub compressor compresses lub teeb liab, nws yuav tsum tau rov qab mus rau nws thawj theem.
Qhov chaw pleev qhov nce tso cai rau koj tig cov zis thiab sib npaug ntawm qhov nce txo qhov tshwm sim thaum compression.
