Kwi bitrate elungileyo engaziwayo kuninzi lwaba bonke. Into engayiyo ibuyiselwa, ngoko ukuguqula kwifomati engalahleki igcina iimeko zangoku kunokuba ibuyisele eyakuqala. AC-3 yisandi esilahlekileyo esingenasiqhagamshelanisi esininzi, sihlala siyi-5.1 kwi-384 okanye 448 kbps, nemetadata yonxibelelwano oluqhelekileyo noluphantsi koxinzelelo.

Kutheni i-soundtrack kwi-diski ihlala i AC3?

Kuba i diski imiselwe ibizwa. Umdlali wayefuna ukucofa isandi kwi sixhobo esiqinileyo- somsebenzi ngaphandle kwesoftware kunye nohlaziyo, ngoko ucaciso lwakhetha udidi olunye nediski nganye ecinezelweyo ukusukela oko ithwale. Le yi nto umfumani uphatha ngaphandle kokukhathazeka kwaye umkhangeli zincwadi awuzukuncamathisela - udidi lwaye kuphi na apho ixabiso liye khona, naphi na. AC-3 yiDolby Digital, ifomati ejikelezayo emiselwe i-laserdisc, iDVD, i-ATSC yosasazo kunye nefilimu ekuqaleni kweeminyaka ye-90.

Kutheni i AC3 ikwidiski ezininzi kunye nokusasazwa ukuba andizange ndiyikhethe?

Kuba ilayisensiwe kwihardware kunokuba ikhethiwe ngumphulaphuli. Ifomati yacaciswa njengeaudio efunekayo yediski ebonakalayo kunye nemigangatho yosasazo oluzenzekelayo, ngoko wonke umdlali, umfumani kunye nebhokisi ebekwe phezulu ikhowudiwe kwiminyaka emininzi kwaye ishishini lezinto eziquletheyo likhowudiwe kulo ngokuhambelana. Lo mmandla wonke kwizixhobo zegumbi lokuhlala uhambelana ngokucacileyo nokungabikho kwayo kwibrowser kunye neapps yefowuni.

Ukuba uthetha ngayo njenge-stereo ixhomekeke kwisiphelo eside: umfumani uya kuqokelela zonke iziqhagamshelanisi, ifowuni iya kuhlambulula ngexesha lokudlala ngaphandle kokungakhathali. Ukutshintsha kwifomati ye-stereo kuphela yenza ukuba uthelekiso luhlale.

Ingaba kubaluleke na ukuba u AC3 uneminyaka engaphezu kweeminyaka ezimashumi amathathu ubudala?

Ubudala ngokwalo alukuyingxaki - iifomati ezininzi ezivela kulo nyaka zihlala zilungile, ngokucacileyo ngenxa yokuba konke kwakuba neminyaka emininzi yokuzisebenzisa. Okubalulekileyo kulapho ixesha licinga khona: iifayile ezincinci, abaqhubi abancinci, akukho msebenzi womnatha, kunye neempawu ezingafunekiyo. apho ezi zinto zicinga khona, ifomati ilungile. apho azisebenzi, le yisizathu sokuguqula.

Iibrawuzeri zikhupha ikhowudi kuluhlu olufutshane, oluqinileyo lweefomati zesandi kwaye AC3 ingaphandle kwayo, ngoko ifayile ikhupha ezantsi endaweni yokudlala okanye umdlali uxela impazamo. Isoftware yedesktop ene codec ebanzi ivula ngaphandle kwengxaki. Ukuba isandi kufuneka idlala kwiphepha le web, ukuguqula kuyilungisa - akukho mdlali wokumiselwa kwenkqubo uza kudibanisa ikhowudi ekhupha ikhowudi ibrawuzeri ayithuthi. AC-3 ayisebenzi kakuhle ngemigangatho yangoku kwaye ayivunyelwanga ziibrowser, iifowuni okanye abadlali abaninzi bewebhu ngaphandle kokudibanisa phantsi kwistereo.

Yintoni i-bitrate ekufuneka ndiyiguqule iifayile zam AC3?

Uthelekiso lwendawo ebekwe kuyo, hayi umthombo. Kwingoma, 256 ukuya 320 kbps icacile kuye wonke umntu ofundayo; kwilizwi kunye nepodcasts, 96 ukuya 128 kbps ininzi kwaye iqulethe ifayile kwakhona. Ukunxulumana ngaphezulu komthombo we bitrate kusezantsi isithuba - igcina ngokunyanisekileyo isandi esisele sidlula kwindlela elahlekile kwaye ayibuyiseli nto ikhowudi yokuqala elahlekile.

Ingaba ukusebenzisa i AC3 kudinga ilayisenisi yepateni?

Ayikuko kuwe. Ii codecs ezibandakanyiweyo ziquka iindidi zepateni, kwaye ilayisensi ibekwe ngabantu abathutha ii decoders - ifowuni, umkhangeli zincwadi, indlela yokusebenza - ixesha elide phambi kokuba ifayile ifike kuwe. Yiyo loo nto ifomati ikho kuyo yonke ihardware kwaye kutheni i royalty- free efana nayo ikhona, kwaye ayitshintshanga nto malunga nokuguqula ifayile oyinayo.

Ingaba ukutshintshela kutshintsha umyinge wesikhokelo sesandi sam AC3?

Ayinaku ukuba ungacela ukuba ikwenze. Uguqulelo lugcina umyinge wombhalo ophambili - 48 kHz uhlala 48 kHz, 44. 1 kHz uhlala 44. 1 kHz - kuba ukuphinda uthathe isampuli kubiza kakhulu umgangatho oncinci ngaphandle koncedo xa akukho nto ifunayo. Izixabiso ziyanele: ii CD zesandi zifuna 44. 1 kHz, abanye abadlali be hardware abadala bavuma akukho nto enye, kwaye imibhobho yelizwi ifuna 16 kHz. Cwangcisa umyinge ngokucacileyo kwezi meko kwaye uyishiye ikhululekileyo ngaphandle kokuba.
