Ib tus kws tshaj lij - lossis tus kws tshaj lij suab suab nws yuav tsum xyuas kom meej tias cov ntaubntawv povthawj siv nyob rau hauv nws lub studio yuav siv sij hawm qhov chaw nrog qhov tsawg tshaj plaws tau ncua - vim hais tias nws yog qhov no uas muaj peev xwm ua tau zoo tsis tau tsuas yog lub koob npe nrov ntawm nws cov hauj lwm, tab sis kuj - tseem ceeb tshaj, qhov kawg kaw.

Thaum pib ntawm tsab xov xwm no, kuv xav hais txog ib qho ntawm cov ntsiab lus uas peb yuav siv tom qab hauv nws. Latency

Latency - Qhov no yog lub sij hawm nws yuav siv sij hawm rau lub suab teeb liab taug kev los ntawm cov tswv yim ntawm lub suab card mus rau qhov kev pab cuam kaw. Lub sijhawm no yog ntsuas hauv milliseconds (ms).

Feem ntau, lub tswv yim yog los xyuas kom meej tias lub teeb liab qeeb theem qis li sai tau thaum kaw.

Qhov ncua sij hawm ntawm lub teeb liab hla lub voj suab card (hauv)> computer> suab card (tawm) tuaj yeem yog los ntawm ob peb mus rau kaum milliseconds. Nws nyob ntawm ob qho tib si ntawm qhov zoo ntawm qhov kev sib txuas siv, qhov loj ntawm qhov thaiv (tsis) thiab kev suav lub zog ntawm lub khoos phis tawj uas peb siv rau kev kaw. Thaum kawg nws yuav tsum kov yeej qhov kev hloov pauv ob ntawm analog rau digital (thiab vice versa) ntawm ADC (Analog-To-Digital) thiab DAC (Digital-To-Analog) converters. Koj yuav tsum tau ntxiv plug-ins siv nyob rau hauv cov kev pab cuam kaw, feem ntau ntawm uas ntxiv ib co ncua "sib nrug".

Lub 10ms latency yuav tsis yog teeb meem rau feem ntau instrumentalists (guitarists, bassists, keyboardists), tab sis nws yuav muaj teeb meem tshwj xeeb tshaj yog rau vocalists, drummers - vim hais tias lawv yuav tsum tau qeeb me ntsis li sai tau thaum lub sij hawm kaw. Koj tsis ntseeg? Ua ib qho kev sim. Teem lub khoos phis tawj kom ua tiav latency saum 20ms (tej zaum qis dua) thiab sim hu nkauj 🙂 Cov lus xaus yuav ncaj nraim.

Yog li koj yuav ua li cas nrog nws?

1) Qhov zoo tshaj plaws…

… (Yog tias peb muaj daim npav suab tsim nyog) peb tuaj yeem siv Direct / USB mix function. Feem ntau cov niaj hnub audio interfaces muaj lub pob qhov rooj uas tso cai rau koj los kho qhov nruab nrab ntawm kev mloog ncaj qha rau qhov nkag mus rau hauv lub interface thiab qhov peb xa rov qab los ntawm lub computer. Nyob rau hauv txoj kev no (thaum kaw cov suab, piv txwv li) peb tuaj yeem mloog lub suab nrog xoom latency - yam tsis tas yuav tsum tau mloog hauv qhov program kaw thiab qhov ntim keeb kwm yav dhau tuaj yeem "sib xyaw" nrog cov hais ncaj qha / USB pob qhov rooj.

Ntau cov ntawv tshaj tawm suab feem ntau muaj cov software ntxiv uas tso cai rau koj los tsim ib tus neeg sib xyaw rau txhua qhov kev tawm suab. Ua li no, thaum kaw cov bands loj, peb tuaj yeem tsim ib qho kev sib xyaw ntawm cov twj paj nruag uas txhua tus neeg ntaus suab paj nruag xav hnov ​​"hauv pob ntseg".

2) Txo qhov thaiv qhov loj / tsis.

Tshawb xyuas seb qhov loj npaum li cas koj siv hauv cov chaw ntawm koj daim npav suab. Hauv qhov nrov Reaper kaw qhov program, cov chaw tsim khoom tau muab cov ntaub ntawv no tso rau hauv lub ces kaum sab xis ntawm lub qhov rais loj, qhov twg I / O latency kuj suav nrog lub sijhawm.

Nws raug nquahu kom teeb tsa qhov tsawg tshaj plaws tsis loj (piv txwv li 64) thaum lub sijhawm kaw kom ntseeg tau tias qhov kev ncua qis tshaj plaws thiab qhov loj tshaj plaws thaum lub sijhawm sib xyaw - kom muaj kev ruaj ntseg siab. Qee zaum, txawm li cas los xij, qhov kev ua tau zoo ntawm lub khoos phis tawj tsis tso cai rau koj los teeb tsa tus nqi qis, yog li qhov no yog qhov chaw rau kev sim - sim seb qhov txiaj ntsig ua haujlwm zoo thiab ruaj khov rau koj - feem ntau (xws li kev kaw guitar) ntau thiab tsawg xws li 128, 256 yog tag nrho.

3) ASIO tsav tsheb yog tus qauv…

… thiab ib zaug dhau los lawv tau los ua cov software hloov kho uas tso cai rau koj kaw suab paj nruag nrog qis latency. Niaj hnub no lawv tau siv nrog feem ntau (txawm tias qib siab heev) daim npav suab - tsuas yog feem ntau hauv cov ntawv kho kom zoo los ua haujlwm nrog lub cuab yeej muab.

Yog tias koj tab tom pib koj txoj kev taug txuj kev nyuaj nrog kev kaw thiab koj siv, piv txwv li, daim npav suab yooj yim tsim rau hauv koj lub computer, koj yuav tsum tau them sai sai rau free ASIO software. Nws yuav tso cai rau koj hloov qhov loj ntawm qhov tsis thiab ua kom zoo dua daim npav suab kom "sab" tawm ntawm nws kom qeeb me ntsis li sai tau.

Qhov software no kuj tso cai rau koj "sib txuas" ob peb daim npav suab rau ntau I / O - tab sis nws tsis pom zoo kom ua li ntawd. Nyob rau hauv qhov kev tshwm sim ntawm xws li ib tug xav tau, nws yog zoo dua mus siv nplooj siab interfaces nrog nthuav kev xaiv (xws li ntawm ADAT).

Tau kawg, muaj lwm txoj hauv kev los daws qhov latency

Xws li kev siv cov khoom siv sab nraud, cov txheej txheem uas tso cai rau koj los tswj lub suab sib xyaw, tab sis feem ntau cov no yuav tsis yog qhov kev daws teeb meem ruaj khov thiab tuaj yeem hloov cov ntaub ntawv mus rau hauv npau suav phem tiag tiag. Peb nyob hauv lub sijhawm uas txhua tus tuaj yeem tsim cov ntaub ntawv zoo heev hauv lawv lub tsev nrog kev pab cuam ntawm kev sib cuam tshuam, cov nqi uas tau nyob rau theem uas peb feem ntau tuaj yeem them tau rau qee lub sijhawm.

Nco ntsoov…

... tias thaum koj xav txog kev sau cia, koj yuav tsum tau saib xyuas tsis yog ntawm cov khoom siv studio, microphones, damping, thiab lwm yam. tag nrho txoj kev mus rau lub hard drive, koj yuav tsis txaus siab (koj thiab - qhov tseem ceeb tshaj) koj cov neeg siv khoom. leej twg, thaum mus rau lub studio, cia siab tias zoo heev thiab kev nplij siab ntawm kev ua hauj lwm.
