Vim li cas koj thiaj xav tau lub suab interface? Lub computer twb muaj ib tug built-in suab card, vim li cas ho tsis siv nws? Los ntawm thiab loj, yog, qhov no kuj yog ib qho interface, tab sis rau ua hauj lwm loj nrog lub suab, lub peev xwm ntawm lub built-in suab card tsis txaus. Pav ca, pheej yig suab thiab txwv kev sib txuas ua rau nws yuav luag tsis muaj txiaj ntsig thaum nws los txog sau thiab ua suab paj nruag.

Feem ntau tus qauv tsim-hauv suab phaib tau nruab nrog ib kab lus nkag rau kev sib txuas ntawm lub tshuab ua suab thiab lwm yam khoom siv zoo sib xws. Raws li cov txiaj ntsig, muaj, raws li txoj cai, qhov tso zis rau lub mloog pob ntseg thiab / lossis cov neeg hais lus hauv tsev.

Txawm hais tias koj tsis muaj cov phiaj xwm loj thiab xav sau koj tus kheej lub suab nkaus xwb lossis, piv txwv li, lub guitar hluav taws xob, daim npav built-in yooj yim tsis muaj qhov tsim nyog connectors . A microphone yuav tsum tau ib qho XLR txuas , thiab lub guitar yuav tsum muaj cov cuab yeej hi-Z input ( siab impedance input). Koj tseem yuav xav tau cov txiaj ntsig zoo uas yuav tso cai rau koj los saib xyuas thiab kho koj cov ntaubntawv povthawj siv siv cov hais lus thiab/los yog lub mloog pob ntseg. Cov txiaj ntsig zoo tshaj plaws yuav ua kom muaj suab nrov tsis muaj suab nrov thiab cuam tshuam, nrog cov txiaj ntsig qis qis - piv txwv li, nyob rau theem tsis muaj rau feem ntau daim npav suab.

Hauv tsab xov xwm no, cov kws tshaj lij ntawm lub khw "Student" yuav qhia rau koj yuav ua li cas xaiv lub suab card uas koj xav tau, thiab tsis them nyiaj ntau dhau tib lub sijhawm.

Koj xav tau dab tsi interface: xaiv los ntawm cov kev txwv

Kev xaiv ntawm interfaces yog qhov zoo, muaj ob peb cov ntsiab tseem ceeb uas koj yuav tsum tsom rau thaum xaiv tus qauv tsim nyog. Yog li nug koj tus kheej cov lus nug:

Kuv xav tau ntau npaum li cas audio inputs/audio outputs?
Hom kev sib txuas rau lub khoos phis tawj / cov khoom siv sab nraud kuv xav tau dab tsi?
Lub suab zoo li cas yuav haum kuv?
Kuv txaus siab siv nyiaj ntau npaum li cas?

Tus naj npawb ntawm inputs/outputs

Nov yog ib qho ntawm feem ntau ib qho tseem ceeb kev txiav txim siab thaum xaiv lub suab interface. Muaj ntau txoj kev xaiv thiab lawv txhua tus sib txawv. Cov qauv nkag-theem yog yooj yim ob-channel desktop interfaces muaj peev xwm ntawm ib txhij kaw nkaus xwb ob suab qhov chaw hauv mono lossis ib qho hauv lub tso suab. Ntawm qhov tod tes, muaj cov tshuab muaj zog uas muaj peev xwm ua tau ib txhij ua ob peb kaum thiab txawm pua pua ntawm cov channel uas muaj ntau lub suab inputs. Txhua yam nyob ntawm seb koj npaj yuav sau dab tsi - tam sim no thiab yav tom ntej.

Rau songwriters uas siv microphones sau lub suab thiab guitar, ib khub sib npaug microphone inputs txaus. Yog ib tug ntawm microphones yog hom condenser, koj yuav xav tau phantom-powered input. Yog tias koj xav kaw ob lub suab guitar thiab suab tib lub sijhawm, ob lub tswv yim yuav tsis txaus , koj yuav xav tau ib tug interface nrog plaub inputs. Yog tias koj npaj yuav kaw hluav taws xob guitar, bass guitar, lossis cov yuam sij hluav taws xob ncaj qha mus rau lub kaw lus, koj yuav xav tau siab impedance ntsuas input (labeled hi-Z)

Koj yuav tsum xyuas kom meej tias tus qauv xaiv interface yog tau tshaj koj lub computer . Txawm hais tias feem ntau cov qauv ua haujlwm ntawm MAC thiab PC, qee qhov tsuas yog sib haum nrog ib lossis lwm lub platform.

Hom sib txuas

Vim muaj kev loj hlob sai hauv cov koob npe ntawm cov suab kaw los ntawm cov khoos phis tawj thiab iOS no, cov kev sib txuas lus niaj hnub no tau tsim los muab kev sib raug zoo nrog txhua yam ntawm cov platforms, kev khiav haujlwm thiab software. Hauv qab no tshaj plaws hom kev sib txuas:

USB: Niaj hnub no, USB 2.0 thiab 3.0 ports muaj nyob rau yuav luag txhua lub computer. Feem ntau USB interfaces tau siv ncaj qha los ntawm lub PC lossis lwm yam khoom siv, ua kom yooj yim rau kev teeb tsa kev sib tham. iOS pab kiag li lawm kuj feem ntau sib txuas lus nrog suab interfaces ntawm USB chaw nres nkoj.

FireWire : pom feem ntau ntawm MAC computers thiab hauv cov qauv interface tsim los ua haujlwm nrog Apple li. Muab cov ntaub ntawv hloov pauv siab thiab yog qhov zoo tagnrho rau kev kaw ntau-channel. Cov tswv PC kuj tuaj yeem siv qhov chaw nres nkoj no los ntawm kev txhim kho lub rooj tsav xwm nthuav dav.

Firewire chaw nres nkoj

Thunderbolt : Ib qho tshiab high-speed txuas technology los ntawm Intel. Txog tam sim no, tsuas yog Macs tshiab kawg nkaus muaj Thunderbolt chaw nres nkoj, tab sis nws kuj tuaj yeem siv rau ntawm PCs nruab nrog kev xaiv Thunderbolt daim npav. Qhov chaw nres nkoj tshiab muab cov ntaub ntawv siab thiab kev ua haujlwm qis kom ua tau raws li cov kev xav tau nruj tshaj plaws ntawm lub computer suab zoo.

PCI e ( PCI Express): pom tsuas yog hauv desktop computers, vim qhov no yog qhov chaw nres nkoj sab hauv ntawm daim npav suab. Txhawm rau txuas PCI e suab cardneed ib tug tsim nyog dawb PCI e slot, uas tsis yog ib txwm muaj. Suab interfaces uas ua haujlwm ntawm PCI e yog mounted nyob rau hauv ib tug tshwj xeeb qhov chaw ncaj qha rau lub computer motherboard thiab muaj peev xwm pauv cov ntaub ntawv nrog nws ntawm lub siab tshaj plaws speeds thiab nrog rau qhov tsawg tshaj plaws tau latency.

suab zoo

Lub suab zoo ntawm koj lub interface ncaj qha nyob ntawm ntawm nws tus nqi. Raws li, high-end qauv nruab nrog digital converters thiab mic preamps tsis pheej yig. Txawm li cas los xij, nrog txhua uas , yog tias peb tsis tham txog kev kaw suab thiab sib xyaw ntawm qib kev tshaj lij studio, koj tuaj yeem nrhiav cov qauv tsim nyog rau tus nqi tsim nyog. Nyob rau hauv lub khw hauv Pupil online, koj tuaj yeem teeb tsa kev tshawb nrhiav los ntawm tus nqi thiab xaiv lub suab interface raws li koj cov peev nyiaj. Cov nram qab no tsis cuam tshuam rau tag nrho cov suab zoo:

ntsis tob: Thaum lub sij hawm cov ntaubntawv povthawj siv, lub analog teeb liab yog hloov dua siab tshiab rau digital, piv txwv li khoom thiab bytes cov ntaub ntawv. Cias muab, qhov ntau dua qhov tob me ntsis ntawm lub suab interface (ntau dua khoom ), qhov siab dua qhov tseeb ntawm lub suab kaw piv rau tus thawj. Qhov tseeb nyob rau hauv cov ntaub ntawv no yog hais txog yuav ua li cas zoo "tus lej" reproduces lub dynamic nuances ntawm lub suab thaum tsis muaj suab nrov.

Ib tug pa suab compact disc (CD) siv 16 -ib audio encryption los muab ib khwv khwv tau ntau yam ua 96db. Hmoov tsis zoo, cov suab nrov hauv cov suab kaw suab yog siab heev, yog li 16- Ntsis cov ntaubntawv povthawj siv yuav inevitably qhia suab nrov nyob rau hauv qhov chaw ntsiag to. 24 -ib ntsis le tau dhau los ua tus qauv rau niaj hnub digital audio kaw, uas muab a khwv khwv tau ntau yam ntawm 144 dB nyob rau hauv tsis muaj yuav luag txhua lub suab nrov thiab zoo amplitude ntau yam rau dynamically contrasting recordings. Qhov 24 -ib audio interface tso cai rau koj los sau cov qib kev tshaj lij.

Qauv tus nqi (Sample tus nqi): hais lus, qhov no yog tus naj npawb ntawm cov "snapshots" ntawm lub suab hauv ib chav tsev ntawm lub sijhawm. Tus nqi yog ntsuas hauv hertz ( Hz ). Tus nqi piv txwv ntawm tus qauv CD yog 44.1 kHz, uas txhais tau hais tias koj cov khoom siv suab digital ua haujlwm 44,100 "snapshots" ntawm lub suab tawm hauv 1 thib ob. Nyob rau hauv txoj kev xav, qhov no txhais tau hais tias lub kaw lus kaw muaj peev xwm khaws cov zaus hauv cov ntau e mus txog 22.5 kHz, uas yog ntau dua cov ntaukev xaav ntawm tib neeg pob ntseg. Txawm li cas los xij, hauv kev muaj tiag, txhua yam tsis yooj yim li ntawd. Yog tsis tau mus rau hauv cov ntsiab lus kev, nws yuav tsum tau muab sau tseg tias, raws li kev tshawb fawb qhia, nrog ib tug nce nyob rau hauv tus nqi piv txwv, suab zoo txhim kho ho. Nyob rau hauv no hais txog, ntau cov kws tshaj lij studios ua lub suab kaw nrog tus lej piv txwv ntawm 48, 96 thiab txawm tias 192 kHz.

Thaum koj tau txiav txim siab lub suab zoo uas koj xav tau, cov lus nug tom ntej no tshwm sim: koj xav siv cov nkauj kaw li cas. Yog tias koj tab tom npaj ua demos thiab sib koom nrog cov phooj ywg lossis cov kws ntaus nkauj, ces 16 -ib /44.1kHz suab interface yog txoj kev mus. Yog tias koj cov phiaj xwm suav nrog kev lag luam kaw, kev ua studio phonogram thiab lwm cov haujlwm tshaj lij lossis tsawg dua, peb qhia koj kom yuav 24 -ib interface nrog ib qho piv txwv zaus ntawm 96 kHz kom tau lub suab zoo.
