Ukubambezeleka - kuyini futhi ubhekana kanjani nakho?

Bona abaqaphi beSitudiyo esitolo se-Muzyczny.pl

Noma yimuphi unjiniyela womsindo oqeqeshiwe - noma ochwepheshe kufanele aqinisekise ukuthi ukuqoshwa ku-studio yakhe kwenzeka ngokulibaziseka okuphansi kakhulu - ngoba yilokhu okukwazi ukonakalisa ngokuphumelelayo idumela lomsebenzi wakhe kuphela, kodwa futhi - okubaluleke kakhulu, ukuqoshwa kokugcina.

Ekuqaleni kwalesi sihloko, ngithanda ukusho elinye lamagama esizowasebenzisa kamuva kuwo. Ukubambezeleka.

I-Latency - lesi yisikhathi esithathayo ukuze isignali yomsindo ihambe isuka kokufakwayo ekhadini lomsindo iye ohlelweni lokurekhoda. Lesi sikhathi silinganiswa ngama-millisecond (ms).

Ngokuvamile, umqondo uwukuqinisekisa ukuthi izinga lokubambezeleka kwesignali liphansi ngangokunokwenzeka ngesikhathi sokuqoshwa.

Ukubambezeleka kwesignali enqamula ikhadi lomsindo weluphu (ku)> ikhompuyutha> ikhadi lomsindo (ngaphandle) kungaba ukusuka kuma-millisecond ambalwa kuye kwamashumi. Kuya kokubili kukhwalithi yesixhumi esibonakalayo esisetshenzisiwe, usayizi webhulokhi (ibhafa) namandla ekhompuyutha ekhompuyutha esiwasebenzisela ukuqopha. Kumele ekugcineni inqobe ukuguqulwa okukabili kwe-analog iye kwedijithali (futhi okuphambene nalokho) ngeziguquli ze-ADC (Analog-To-Digital) kanye ne-DAC (Digital-To-Analog). Kufanele futhi wengeze ama-plug-in asetshenziswe kuhlelo lokurekhoda, iningi lazo elengeza ukubambezeleka okuthile “okuhlukene”.

Ukubambezeleka kwe-10ms ngeke kube inkinga kubadlali bezinsimbi abaningi (abashaya isiginci, abashaya i-bass, abashaya ikhibhodi), kodwa kungaba yinkinga ikakhulukazi kwabaculayo, abashaya izigubhu - ngoba badinga ukubambezeleka okuncane ngangokunokwenzeka ngesikhathi sokurekhoda. Anikholwa na? Yenza isilingo. Setha ikhompuyutha ukuze ufinyelele ukubambezeleka okungaphezu kuka-20ms (mhlawumbe ngisho nangaphansi) bese uzama ukucula 🙂 Iziphetho zizobe ziqondile.

Pho ubhekana kanjani nakho?

1) Okungcono kakhulu…

… (Uma sinekhadi lomsindo elifanele) singasebenzisa umsebenzi we-Direct/USB mix. Izixhumanisi zomsindo eziningi zesimanje zinefindo elikuvumela ukuthi ulungise phakathi kokulalela ngokuqondile lokho okungena kusixhumi esibonakalayo nesikubuyisela emuva sisuka kukhompuyutha. Ngale ndlela (uma siqopha amazwi, ngokwesibonelo) singalalela iphimbo nge-zero latency - ngaphandle kwesidingo sokulalela ohlelweni lokurekhoda futhi ivolumu yangemuva "ingahlanganiswa" ne-knob eshiwo Direct / USB.

Amakhadi omsindo athuthuke kakhulu ngokuvamile anesofthiwe eyengeziwe ekuvumela ukuthi udale amamiksi angawodwana kunoma yikuphi okuphumayo. Ngale ndlela, lapho siqopha amabhendi amakhulu, singakha ingxube ngayinye yezinsimbi umculi ngamunye afuna ukuzizwa “endlebeni”.

2) Yehlisa usayizi webhulokhi / ibhafa.

Hlola ukuthi yimuphi usayizi webhafa owusebenzisayo kuzilungiselelo zekhadi lakho lomsindo. Kuhlelo lokuqopha oludumile lwe-Reaper, umenzi ubeke lolu lwazi ekhoneni eliphezulu kwesokudla sewindi elikhulu, lapho ukubambezeleka kwe-I / O nakho kubalwa ngesikhathi sangempela.

Kunconywa ukusetha usayizi webhafa omncane kakhulu (isb. 64) ngesikhathi sokurekhoda ukuze kuqinisekiswe ukubambezeleka okuphansi okungenzeka kanye nokukhulu kakhulu ngesikhathi sokuhlanganisa - ukuze kube nokuzinza okuphezulu. Kwesinye isikhathi, nokho, ukusebenza kwekhompuyutha akukuvumeli ukuthi uhlele inani eliphansi kangako, ngakho-ke lena inkambu yokuhlola - zama ukuthi yimaphi amanani asebenza kahle futhi azinzile kuwe - ngokuvamile (isb. okuqoshiwe kwesiginci) osayizi abafana 128, 256 zilungile ngokuphelele.

3) Abashayeli be-ASIO bajwayelekile…

… futhi ngesinye isikhathi baba isoftware eguquguqukayo ekuvumela ukuthi uqophe umculo nge-latency ephansi. Namuhla asetshenziswa namakhadi omsindo amaningi (ngisho athuthuke kakhulu) - ngokuvamile kuphela ezinguqulweni ezilungiselelwe ukusebenza ngomshini othile.

Uma uqala uhambo lwakho ngokurekhoda futhi usebenzisa, isibonelo, ikhadi lomsindo elilula elakhelwe kukhompyutha yakho, kufanele nakanjani ulinake. khulula Isoftware ye-ASIO. Izokuvumela ukuthi uguqule usayizi webhafa futhi wenze ikhadi lomsindo libe ngcono ukuze "ucindezele" liphume kulo njengokulibaziseka okuncane ngangokunokwenzeka.

Le softhiwe futhi ikuvumela ukuthi "uhlanganise" amakhadi omsindo amaningana ukuze uthole i-I / O eyengeziwe - kodwa ayinconywa ukwenza kanjalo. Uma kunesidingo esinjalo, kungcono ukusebenzisa izixhumanisi ezizinikezele ezinezinketho zokunweba (isb nge-ADAT).

Yiqiniso, zikhona ezinye izindlela zokubhekana ne-latency

Njengokusebenzisa i-mixer yangaphandle, isethi evumela ukuthi ulawule ukuxubana komsindo, kodwa ezimweni eziningi lezi ngeke zibe yisixazululo esizinzile futhi zingashintsha okuqoshiwe kube yiphupho elibi langempela. Siphila esikhathini lapho wonke umuntu engakha izinto ezizwakala kahle kakhulu emzini wakhe ngosizo lwezindawo zokusebenzelana, amanani azo abe sezingeni iningi lethu elingakwazi ukulikhokhela isikhathi esithile.

Khumbula…

… ukuthi uma ucabanga ngokuqopha okuphrofeshinali, udinga ukunakekela hhayi kuphela imishini yesitudiyo yochwepheshe, imibhobho, ukudambisa, njll. yonke indlela eya ku-hard drive, awusoze waneliseka ngokugcwele (yakho futhi – okubaluleke kakhulu) amaklayenti akho. okuthi, lapho beya esitudiyo, balindele ikhwalithi enhle kakhulu nokunethezeka okuphezulu komsebenzi.
