Latency - ndi chiyani ndipo mumathana nayo bwanji?

Onani oyang'anira ma Studio mu sitolo ya Muzyczny.pl

Katswiri aliyense - kapena mainjiniya omveka bwino ayenera kuonetsetsa kuti kujambula mu studio yake kumachitika ndi kuchedwa kochepa kwambiri - chifukwa ndi izi zomwe zimatha kuwononga bwino osati mbiri ya ntchito yake, komanso - chofunika kwambiri, zolemba zomaliza.

Kumayambiriro kwa nkhaniyi, ndikufuna nditchule limodzi mwa mawu amene tidzawagwiritse ntchito m’tsogolomu. Kuchedwa.

Latency - ino ndi nthawi yomwe imafunika kuti chizindikiro cha audio chichoke pa zolowetsa pa khadi lamawu kupita ku pulogalamu yojambulira. Nthawiyi amayezedwa mu ma milliseconds (ms).

Nthawi zambiri, lingaliro ndikuwonetsetsa kuti mulingo wochedwa wazizindikiro ndi wotsika momwe mungathere panthawi yojambulira.

Kuchedwa kwa siginecha kudutsa lupu lomveka khadi (mu)> kompyuta> phokoso khadi (kunja) kungakhale kuchokera angapo mpaka makumi milliseconds. Zimatengera mtundu wa mawonekedwe omwe amagwiritsidwa ntchito, kukula kwa chipika (buffer) ndi mphamvu yamakompyuta ya kompyuta yomwe timagwiritsa ntchito pojambulira. Iyenera kugonjetsa kusinthika kawiri kwa analogi kukhala digito (ndi mosemphanitsa) kudzera pa ADC (Analog-To-Digital) ndi DAC (Digital-To-Analog) converters. Muyeneranso kuwonjezera mapulagini omwe amagwiritsidwa ntchito mu pulogalamu yojambulira, ambiri omwe amawonjezera kuchedwa "kosiyana".

Kuchedwa kwa 10ms sikudzakhala vuto kwa oimba zida zambiri (oyimba gitala, oimba mabasi, oimba ma keyboard), koma akhoza kukhala ovuta makamaka kwa oimba, oimba ng'oma - chifukwa amafuna kuchedwa pang'ono momwe angathere pojambula. Simukhulupirira? Chitani zoyeserera. Khazikitsani kompyuta kuti ikwaniritse latency pamwamba pa 20ms (mwina ngakhale yotsika) ndikuyesera kuyimba 🙂 Mapeto adzakhala olunjika.

Ndiye mumathana nazo bwanji?

1) Zabwino kwambiri…

… (Ngati tili ndi khadi yomvera yoyenera) titha kugwiritsa ntchito Direct / USB mix. Malo ambiri amakono amawu ali ndi knob yomwe imakulolani kuti musinthe pakati pa kumvetsera mwachindunji zomwe zimalowa mu mawonekedwe ndi zomwe timatumiza kuchokera pa kompyuta. Mwa njira iyi (polemba mawu, mwachitsanzo) tikhoza kumvetsera mawu ndi zero latency - popanda kufunikira kumvetsera pulogalamu yojambulira ndipo voliyumu yakumbuyo ikhoza "kusakanikirana" ndi Direct / USB knob.

Makhadi amawu apamwamba kwambiri nthawi zambiri amakhala ndi mapulogalamu owonjezera omwe amakulolani kuti mupange zosakaniza zapayekha pazotulutsa zilizonse. Mwa njira iyi, pojambula magulu akuluakulu, tikhoza kupanga kusakaniza kwapadera kwa zida zomwe woimba aliyense amafuna kumva "m'khutu".

2) Chepetsani kukula kwa block / buffer.

Yang'anani kukula kwake kwa buffer komwe mukugwiritsa ntchito pazokonda za khadi lanu lamawu. Mu pulogalamu yotchuka yojambulira ya Reaper, wopanga adayika izi pakona yakumanja kwa zenera lalikulu, pomwe I / O latency imawerengedwanso munthawi yeniyeni.

Ndibwino kuti mukhazikitse kukula kocheperako (mwachitsanzo 64) panthawi yojambulira kuti muwonetsetse kuti kuchedwa kocheperako komanso kwakukulu kwambiri panthawi yosakaniza - kuti mukhale okhazikika. Nthawi zina, komabe, magwiridwe antchito amakompyuta samakulolani kuyika mtengo wotsika chotere, kotero iyi ndi gawo loyesera - yesani zomwe zimagwira ntchito bwino komanso mokhazikika kwa inu - nthawi zambiri (mwachitsanzo, zojambulira gitala) monga 128, 256 ali bwino kwathunthu.

3) oyendetsa ASIO ndi muyezo ...

... ndipo nthawi ina adakhala mapulogalamu osintha omwe amakulolani kuti mujambule nyimbo ndi latency yotsika. Masiku ano amagwiritsidwa ntchito ndi makhadi omvera ambiri (ngakhale apamwamba kwambiri) - nthawi zambiri m'matembenuzidwe okonzedwa kuti azigwira ntchito ndi chipangizo china.

Ngati mukuyamba ulendo wanu ndi kujambula ndipo mumagwiritsa ntchito, mwachitsanzo, khadi lomveka lopangidwa mu kompyuta yanu, muyenera kumvetsera. kwaulere Pulogalamu ya ASIO. Zikuthandizani kuti musinthe kukula kwa buffer ndikuwongolera khadi lamawu kuti "mufinyize" kuti muchedwe pang'ono momwe mungathere.

Pulogalamuyi imakupatsaninso mwayi "kuphatikiza" makhadi angapo amawu kuti muwonjezere I / O - koma sizovomerezeka kutero. Pakafunika kufunikira kotere, ndibwino kugwiritsa ntchito njira zolumikizirana ndi njira zowonjezera (mwachitsanzo kudzera pa ADAT).

Inde, pali njira zina zothanirana ndi latency

Monga kugwiritsa ntchito chosakaniza chakunja, seti yomwe imakupatsani mwayi wowongolera kusakanikirana kwa mawu, koma nthawi zambiri izi sizidzakhala zokhazikika ndipo zimatha kutembenuza zojambula kukhala zovuta zenizeni. Tikukhala mu nthawi imene aliyense akhoza kupanga zipangizo zomveka bwino kwambiri m'nyumba mwawo mothandizidwa ndi zolumikizira, mitengo yomwe yakhala pamlingo womwe ambiri aife tingakwanitse kwa nthawi ndithu.

Kumbukirani…

... kuti pamene mukuganiza za kujambula akatswiri, muyenera kusamalira osati akatswiri situdiyo zipangizo, maikolofoni, damping, etc. mpaka pa hard drive, simudzakhutitsidwa mokwanira (zanu ndi - chofunika kwambiri) makasitomala anu. omwe, popita ku studio, amayembekeza ntchito yabwino kwambiri komanso chitonthozo chambiri.
