'Ilizwi lomphefumlo' kwiiCinema zabucala: Njanii-subwoofer yobungcaliukwenza amabali eemuvi angene nzulu ezintliziyweni zabantu?

Uphando lubonisa ukubaiziphumo zebhesi ezikumgangatho ophezuluinokunyusa ukuntywiliselwa kokubukela ngama-60% kunye nokwanda kweemvakalelo ngama-45%

Xa kufika umboniso wokuqhuma kwimuvi,i-subwooferayipheleli nje ekunikezeleniisandi, kodwa kwakhona umothuko obetha intliziyo; Xa isantya sentliziyo somlinganiswa ophambili sinyuka ngokukhawuleza, ukubetha kwentliziyo okudluliselwa yi-subwoofer kwenza abaphulaphuli babe novelwano. Kwii-cinema zabucala, umphefumlo kaiinkqubo zesandi zobungcaliivela kulawulo oluchanekileyo lwe-resonance yeemvakalelo yi-subwoofer.

I-subwoofer idlala indima yenjini yeemvakalelo kwiibhanyabhanya zabucala. Ngokusebenzisa indlela echanekileyo yokuqhubaii-amplifier zedijithaliI-subwoofer inokubuyisela iinkcukacha ezicebileyo ze-low-frequency ngaphakathi koluhlu lwe-20Hz-120Hz. Nokuba kukugquma okukhulu kwemingxuma emnyama kwi-Interstellar okanye ukuwa okumangalisayo kwe-low-frequency yamaphupha kwi-Inception, zinokuboniswa ngokugqibeleleyo. Ulawulo olukrelekrele lweiprosesaiqinisekisa unxibelelwano olugqibeleleyo phakathi kwesiphumo se-low-frequency kunye ne-frequency ephakathi ukuya phezulu ye-isithethi sekholamu, ukudala ukungasebenzi kakuhleintsimi yesandiamava. Eyona nto ibalulekileyo kukusebenza ngokubambisana kweeyunithi ezininzi ezisetyenziswa kwi-subwoofer yanamhlanje, ephelisa ngempumelelo ukuphazamiseka kwesandi ngokusebenzisa izakhiwo ze-acoustic ezibalwe ngokuchanekileyo, ukuqinisekisa ukuba yonke inkcukacha yesandi esisezantsi icacile kwaye iyahluka.

I-power sequencerIdlala indima echanekileyo yokuvumelanisa kwinkqubo. Iqinisekisa ukuba isiphumo sothuko se-subwoofer siboniswa ngokuhambelana nesicwangciso esibonakalayo kwi-milliseconds: isandi sokuqhuma kunye nokuqhuma komlilo kuhambelana ngoko nangoko, kwaye imifanekiso yeendudumo kunye nombane ihambelana ngokugqibeleleyo. Olu lawulo lwexesha oluchanekileyo luvumela abaphulaphuli ukuba bazintywilisele ngokupheleleyo kwihlabathi le-audiovisual elenziwe ngumlawuli. I-power sequencer ephucukileyo ikwanomsebenzi wokufunda okrelekrele, onokulungisa ngokuzenzekelayo iiparameter zokulibaziseka ngokohlobo lwemuvi, okuvumela ukuvumelanisa iaudio kunye nevidiyo ukufikelela kwimeko efanelekileyo.

Iumxube wesandiivumela abanini besinema ukuba benze ngokwezifiso ukucutshungulwa ngokwehlobo lwefilimu. Ngokulungisa ngokuchanekileyo umxube wesandi, iimuvi zentshukumo zinokubonisa iziphumo eziphantsi kwemvamisa, ngelixa iimuvi zobugcisa zinokubonisa iziphumo ezibuthathaka ngakumbi zemvamisa esezantsi yemvamisa. Vavanya umsebenzi wokulinganisa isandi ngokuzenzekelayo weimakrofonikunye neprosesa, enokwenza ngcono ngokuzenzekelayo impendulo yefrikhwensi ye-subwoofer ngokusekelwe kwiiimpawu ze-acousticyegumbi kwaye kuthintelwe ukuphazamiseka kwamaza amiyo.

Umsebenzi wokubambisana weinkqubo yesithethi yobungcaliiphucula ukusebenza kwe-subwoofer. Isithethi esikwikholamu sinoxanduva lokunika intetho ecacileyo kunye nobuthathakaiziphumo zesandi, ngelixa i-subwoofer igxile ekudaleni umoya ovuselela iimvakalelo. Olu hluhlu lwabasebenzi kunye nentsebenziswano luvumela iicinema zabucala ukuba zibonise imiboniso bhanyabhanya eyoyikisayo kunye namaxesha encoko achukumisayo.

Ngamafutshane, i-subwoofer kwii-cinema zabucala ingaphezulu kakhulu kune-isixhobo sesandi, yibhulorho edibanisa iimvakalelo zefilimu neentliziyo zabaphulaphuli. Ngokusebenzisa amandla okukhulisa ii-amplifiers zedijithali, ulawulo olukrelekrele lweiiprosesa, ulungelelwaniso oluchanekileyo lweabalandelelanisi bamandla, ukulungiswa okulungiselelwe wenaabaxubi besandikunye nokulinganiswa kovavanyo ngokwesayensiiimayikrofoniI-subwoofer ishiya uphawu olucacileyo kuyo yonke ifilimu esezintliziyweni zabaphulaphuli. Ukutyala imali kwi-"inkqubo yesandi yobungcaliixhotyiswe ngei-subwoofer yomgangatho ophezuluifaka "ilizwi elichukumisayo" kakhulu kwiibhanyabhanya zabucala.
