'Ilizwi loMphefumlo' kwiiCinema zaBucala: Njanisubwoofer yobungcaliukwenza amabali emuvi amiliselwe nzulu ezintliziyweni zabantu?

Uphando lubonisa ukubaiziphumo eziphezulu ze-bassinokunyusa ukuntywiliselwa kokubukela nge-60% kunye ne-resonance yeemvakalelo nge-45%

Xa indawo yokuqhuma ifika kwi-movie, isubwooferayinikezeli kuphelaisandi, kodwa kwanomothuko obetha intliziyo; Xa isantya sentliziyo ye-protagonist ikhawuleza, i-pulse ehanjiswa yi-subwoofer yenza abaphulaphuli babe novelwano. Kwii-cinema zabucala, umphefumlo weIinkqubo zesandi zobuchuleivela kulawulo oluchanekileyo lwe-resonance yeemvakalelo nge-subwoofer.

I-subwoofer idlala indima yenjini yeemvakalelo kwii-cinema zabucala. Ngokuqhuba ngokuchanekileyo kweiamplifiers zedijithali, i-subwoofer inokubuyisela iinkcukacha ezityebileyo ze-low-frequency ngaphakathi koluhlu lwe-20Hz-120Hz. Nokuba kukugquma okunzulu kwemingxunya emnyama kwi-Interstellar okanye kukuwa kwamaphupha okuyothusayo kwi-Inception, zinokubonakaliswa ngokugqibeleleyo. Ulawulo olukrelekrele lweiprosesaiqinisekisa uxhulumaniso olugqibeleleyo phakathi kwefuthe eliphantsi-frequency kunye ne-mid ukuya kwi-frequency ephezulu yeisithethi sekholamu, ukudala i-seamlessindawo yesandiAmava. Eyona nto iphawulwayo bubuchwephesha bokusebenzisana beeyunithi ezininzi obusetyenziswa kwi-subwoofer yanamhlanje, ephelisa ngokufanelekileyo ukugqwetheka kwe-resonance ngokusebenzisa izakhiwo ze-acoustic ezibalwe ngokuchanekileyo, iqinisekisa ukuba zonke iinkcukacha ezisezantsi zicacile kwaye ziyahlukaniseka.

Isilandeleli samandlaidlala indima echanekileyo yongqamaniso kwinkqubo. Iqinisekisa ukuba umphumo wokutshatyalaliswa kwe-subwoofer uboniswa ngokuvumelanisa kunye nesicwangciso esibonakalayo kwi-milliseconds: isandi sokuqhuma kunye nokuqhuma komlilo ngokukhawuleza kuhambelana, kunye nemifanekiso yokuduma kunye nemibane ihambelana ngokugqibeleleyo. Olu lawulo lwexesha oluchanekileyo luvumela abaphulaphuli ukuba bazicwilise ngokupheleleyo kwihlabathi le-audiovisual elenziwe ngumlawuli.I-sequencer yamandla ephuculweyo nayo inomsebenzi wokufunda okrelekrele, onokunyusa ngokuzenzekelayo iiparameters zokulibaziseka ngokohlobo lwe-movie, ukuvumela ungqamaniso lwe-audio kunye nevidiyo ukufikelela kweyona ndawo ingcono.

Iumxhubi womsindoivumela abanini bhanyabhanya ukuba benze ulungelelwaniso ngokohlobo lwefilimu. Ngohlengahlengiso oluchanekileyo lomxube weaudio, iimuvi zentshukumo zinokubonisa iziphumo ezisezantsi, ngelixa iifilimu zobugcisa zinokubonisa iziphumo ezibuthathaka ngakumbi ngokweemvakalelo. Vavanya umsebenzi wolungelelwaniso lwesandi oluzenzekelayo lweimayikrofoningentsebenziswano neprosesa, enokwandisa ngokuzenzekelayo impendulo yefrikhwensi ye-subwoofer esekwe kwiiimpawu ezivakalayoyegumbi kunye nokuphelisa uphazamiseko lwamaza omileyo.

Umsebenzi wentsebenziswano weinkqubo yesithethi sobuchuleyandisa ukusebenza kwe-subwoofer. Isithethi sekholamu sinoxanduva lokunikezela ngengxoxo ecacileyo kunye nobuthathakaiziphumo zesandi, ngelixa i-subwoofer igxile ekudaleni umoya weemvakalelo. Eli candelo labasebenzi kunye nentsebenziswano livumela iicinema zabucala ukuba zibonise imiboniso eyonwabisayo eqhumayo kunye namaxesha encoko achukumisayo.

Isishwankathelo, i-subwoofer kwii-cinema zabucala zingaphezulu kakhulu kuneisixhobo sesandi, yibhulorho edibanisa iimvakalelo zefilimu kunye neentliziyo zabaphulaphuli. Ngokuqhuba okunamandla kweeamplifiers zedijithali, ulawulo olukrelekrele lweiiprosesa, ungqamaniso oluchanekileyo lweabalandeleli bamandla, ulungelelwaniso lobuqu lweabaxube bomsindo, kunye nolungelelwaniso lwenzululwazi lovavanyoimibhobho, i-subwoofer ishiya imprint enzulu kuyo yonke ifilimu yeefilimu ezintliziyweni zabaphulaphuli. Ukutyala imali kwiinkqubo yesandi yobuchuleixhotyiswe ngei-subwoofer ekumgangatho ophezuluitofa elona “lizwi lichukumisayo” kwiimovie zabucala.
