Audio equalizers hloov cov zaus teb cov yam ntxwv ntawm lub kaw lus. Thaum tham txog lub ntsiab lus ntawm lub suab sib npaug, lossis "EQs," koj yuav xav txog cov hom uas muaj nyob hauv tsev ua yeeb yam lossis lub tso suab tsheb. Txawm li cas los xij, ntau lub suab nrov thiab cov cuab yeej siv niaj hnub no muaj qee cov qauv ntawm lub suab sib npaug.
Tus EQ tuaj yeem yog qhov yooj yim li lub portable Bluetooth hais lus nrog cov pob qhov rooj los kho cov ntses bass thaj tsam thiab treble qib. Los yog nws yuav nyuaj dua, xws li cov duab sib npaug pom hauv qee lub suab paj nruag apps.
Qhov tseem ceeb ntawm Suab Equalizers
Qhov zoo tshaj plaws lub suab sib npaug muab ntau dua thiab raug tswj hwm lub suab thiab zaus-kev dhia dhau tsuas yog ntses bass thaj tsam thiab treble. Lawv tuaj yeem txhawb lossis txiav cov decibel tso zis ntawm cov zaus tshwj xeeb.
Qee lub suab tso suab hauv tsev lossis lub suab nrov muaj kev tswj hwm lub suab sib luag nrog ntau qib ntawm kev tswj, suav nrog tus neeg swb lossis tus xov tooj. Lawv kuj tseem yuav muaj cov duab digital tswj los ntawm cov chaw taws teeb.
Yog tias koj lub receiver lossis amplifier tsis tso cai rau koj los tweak lub kaw lus lub suab tso tawm raws li koj nyiam, siv lub suab sib npaug. Thaum muaj ntau hom suab sib npaug, ob qho tib si feem ntau yog duab thiab parametric. Nov yog yam koj yuav tsum paub txog lawv.
Dab tsi yog Graphic Equalizers?
Ib daim duab vaj huam sib luag yog hom yooj yim ntawm lub suab sib npaug, feem ntau ntaus pob ncaws pob ntau tus swb lossis tswj kev txhawb nqa lossis txiav cov qhab. Tus naj npawb ntawm kev tswj tus kheej tuaj yeem sib txawv los ntawm kev tsim thiab qauv. Piv txwv li, ib tug raug tsib-band graphic equalizer muaj sliders rau tsib lub frequencies: 30 Hz (tsawg bass), 100 Hz (mid-bass), 1 kHz (midrange), 10 kHz (saum nruab nrab), thiab 20 kHz (treble. los yog high-frequency).
Ib kaum-band equalizer muaj cov sliders rau kaum qhov chaw ruaj khov-feem ntau cov uas tau hais los saum toj no thiab tsib ntau zaus bands. Ntau bands txhais tau tias kev tswj dav dua ntawm cov zaus spectrum. Txhua qhov kev ruaj khov tuaj yeem txhawb nqa lossis txiav mus rau qhov siab tshaj plaws lossis tsawg kawg. Nyob ntawm qhov tsim thiab qauv, qhov ntau yuav yog +/- 6 dB lossis tej zaum +/- 12 dB.
Yuav ua li cas Graphic Equalizers txawv
Nws yog ib qho tseem ceeb kom nkag siab txog cov duab sib npaug. Thaum koj kho tus slider, nws kuj cuam tshuam rau cov nyob sib ze frequencies.
Xav txog qhov tshwm sim thaum koj hnia tus ntiv tes rau hauv hnab yas uas npog lub tais. Raws li tus ntiv tes nias rau hauv cov yas, nws tsim cov nyhuv nqes hav. Cov cheeb tsam ze tshaj plaws ntawm tus ntiv tes yog cuam tshuam ntau dua los ntawm txoj kab nqes dua li thaj chaw nyob deb. Pushing harder kuj intensifies txoj kab nqes piv rau lub teeb poke.
Txoj ntsiab cai tib yam no siv tau li cas cov duab vaj huam sib luag tswj kev hloov pauv zaus thaum txhawb lossis txiav cov hlua. Hauv cov ntsiab lus, cov duab vaj huam sib luag muab:
- kev ua haujlwm yooj yim thiab nkag siab
- Txhim kho zaus
- Ntau yam ntawm kev tswj hwm ntau zaus
- pob khoom kim dua li parametric EQs
Parametric Equalizers yog dab tsi?
Parametric equalizers yog qhov nyuaj dua li cov duab sib npaug vim koj tuaj yeem hloov kho ntxiv dhau qhov ntim. Parametric equalizer cia koj tswj peb yam: theem (boosting los yog txiav decibels), qhov tseeb zaus, thiab lub bandwidth los yog ntau yam (tseem hu ua Q los yog quotient ntawm kev hloov) ntawm txhua zaus. Xws li, parametric equalizers muab kev phais qhov tseeb thaum nws los cuam tshuam rau lub suab tag nrho.
Zoo li cov duab sib npaug, txhua zaus tuaj yeem txiav lossis txhawb nqa. Tab sis thaum cov duab vaj huam sib luag tau ruaj khov, parametric equalizers tuaj yeem xaiv qhov chaw lossis thawj zaus. Piv txwv li, yog tias cov duab vaj huam sib luag muaj kev tswj xyuas tas li ntawm 20 Hz, parametric equalizer tuaj yeem hloov kho kom tswj cov zaus ntawm 10 Hz, 15 Hz, 20 Hz, 25 Hz, 30 Hz, thiab lwm yam. Kev xaiv cov zaus hloov tau (piv txwv li, los ntawm ib qho, tsib, lossis kaum) sib txawv los ntawm kev tsim thiab qauv.
Yuav ua li cas Parametric Equalizers Tswj Bandwidth thiab Ntau
Ib tus parametric sib npaug tuaj yeem tswj tau qhov bandwidth-qhov nqes hav uas cuam tshuam rau cov neeg nyob sib ze-ntawm txhua tus neeg zaus. Piv txwv li, yog tias qhov nruab nrab zaus yog 30 Hz, qhov dav bandwidth kuj tseem cuam tshuam cov zaus qis li 15 Hz thiab siab li 45 Hz. Qhov nqaim bandwidth tsuas yog cuam tshuam cov zaus tsawg li 25 Hz thiab siab li 35 Hz.
Thaum tseem muaj cov nyhuv nqes hav, parametric equalizers tau zoo dua tuaj yeem xoom rau hauv thiab kho cov duab ntawm cov zaus tshwj xeeb yam tsis muaj kev cuam tshuam lwm tus. Qhov kev tswj kom ntxaws ntawm lub suab thiab lub suab tso cai rau kev hloov kho kom haum raws li qhov xav tau lossis lub hom phiaj (xws li kev sib xyaw lossis kaw suab).
Hauv qhov nutshell, parametric equalizers muab:
- Kev ua haujlwm nyuaj thiab txhob txwm ua haujlwm
- Xaiv hloov zaus
- precise range of effect
- Kev ua yeeb yam rau studio kaw, sib xyaw, thiab tsim khoom
- pob khoom kim dua li cov duab sib npaug
