Limiter vs Compressor
Limiters thiab compressor yog cov khoom siv hluav taws xob zoo siv hauv kev tsim suab thiab kaw. Lub limiter txwv lub suab theem thiab lub compressor nce lub compactness ntawm lub suab. Lawv lub luag haujlwm tseem ceeb yog khaws cov qib ntim qis dua qib tau txiav txim siab hauv cov chaw kaw suab.
Ntau txog Compressor
A compressor yog ib qho kev tivthaiv uas txo cov suab nrov ntawm cov suab paj nruag, txo qhov sib txawv ntawm qhov nrov tshaj plaws thiab suab nrov tshaj plaws hauv cov suab paj nruag. Qhov no yog ua tiav los ntawm attenuating lub louder signals thiab amplifying lub quieter signals.
Nyob hauv cov txheej txheem compression, cov hauv qab no raug txiav txim siab thiab hloov pauv.
Threshold: lub siab txwv ntawm lub suab nrov ua ntej siv compression.
Compression Ratio: qib ntawm compression yuav tsum tau thov. Piv txwv li, yog hais tias tus compression piv yog teem raws li 8: 1, cov zis teeb liab tsuas yog ib yim ntawm cov tswv yim teeb liab.
Attack: qhov ceev ntawm cov lus teb rau lub compressor.
Release: ncua sij hawm rau lub teeb liab poob tom qab ncav cuag qhov pib.
Knee: qhov xwm txheej ntawm cov tshuaj tiv thaiv tom qab qhov pib mus txog los ntawm lub teeb liab tawm.
Hard Knee – clamps lub teeb liab tam sim ntawd, Lub hauv caug mos – compression pib maj mam raws li lub teeb liab txhim kho ntxiv dhau qhov pib.
Txhob Tau Txais: txij li thaum lub compression attenuates lub teeb liab no feature tso cai rau koj kom amplify lub teeb liab los them rau qhov poob ntawm lub teeb liab zog.
Cov hom compressor tseem ceeb siv hauv kev tswj hwm suab thiab kaw yog VCA, Opto (optical), FET, thiab valve compression cov txheej txheem.
Ntau txog Limiter
Limiters, es tsis txhob txo cov qhab ntawm ob qhov kawg ntawm lub teeb liab nrov, ua tsuas yog hauv thaj tsam nrov ntawm pawg. Raws li lub npe implies, nws lub hom phiaj yog txwv tsis pub lub teeb liab thaum mus txog ib theem txiav txim los ntawm attenuating lub teeb liab. Tsuas yog nws tsim qhov txwv siab tshaj plaws rau qib suab, tab sis tsis muaj qis dua.
Los ntawm ib qho kev xav, lub limiter tuaj yeem pom tau tias yog ib qho kawg compressor, yog li ntawd, yog ib qho ntawm cov compressors. Yog li ntawd, tag nrho cov limiters yog compressors, tab sis tsis yog tag nrho cov compressors yog limiters. Limiters yog siv rau hauv kev txo qis heev thiab ua raws li kev tiv thaiv overload thiab. Tsis tas li ntawd, txwv tsis pub muaj lub sijhawm tawm tsam sai dua thiab tso tawm lub sijhawm, yog li ntawd, muaj peev xwm teb tau sai sai, tsis muaj kev cuam tshuam cov teeb liab zoo.
Qhov txawv ntawm Compressor thiab Limiter yog dab tsi?
• Lub tshuab compressor yog siv los txo qis qhov sib txawv ntawm lub suab los ntawm kev txo qis qis thiab qib suab siab tshaj plaws, thaum cov txwv tsuas yog xav txog cov suab nrov tshaj plaws.
• Cov txwv muaj lub sijhawm teb sai dua thiab lub sijhawm tso tawm.
• Limiters yog siv rau kev tiv thaiv overload, thaum compressors yog siv rau kev hloov kho dua tshiab.
