T"indlela yokutshintsha indawo"i-subwoofer: Unga kanjaniiinkqubo zesandi zesinema zobungcaliukufezekisa isandi esikhulu semiboniso emikhulu kumagumbi amancinci?

Ubungqina besayensi bubonisa ukuba ulawulo oluchanekileyo lwe-low frequency lunokunyusa ukuntywiliselwa kwiindawo ezincinci ze-cinema ngama-60%, ngelixa lunciphisa ukuphazamiseka kwamaza okuma ngama-80%

Kwindawo yemidlalo yeqonga yasekhaya engaphantsi kweemitha ezingama-20 zesikwere, iinkqubo zebhasi zemveli zihlala zijongene nengxaki: isandi esiphantsi asinayo i-shock, ngelixa isandi esiphezulu senza ingxolo engacacanga kunye namaza amileyo acaphukisayo. Kule mihla, i-inkqubo yesandi yobungcaliisekelwe kwingcaciso echanekileyoi-acousticIzibalo zibhala ngokutsha ngokupheleleyo imithetho ye-acoustic yee-cinema zesithuba esincinci ngokusebenzisa iteknoloji ye-subwoofer ekrelekrele kunye nokucubungula isignali okuphambili.

Ukulungiswa kwendawoiinkqubo zesandi zobungcaliIqala ngemephu echanekileyo ye-acoustic. Iingcali zisebenzisa ukulinganisaiimayikrofoniukwenza ukuskena igumbi ngamanqaku amaninzi, kunyeiprosesaiseka imodeli ye-acoustic enamacala amathathu esekelwe kwidatha eqokelelweyo ukuze ichonge ngokuchanekileyo i-resonance frequency kunye nama-standing wave nodes egumbi. Le datha isebenza njengesicwangciso esisisiseko senkqubo ye-subwoofer ukuze itshintshe indawo. Umsebenzi wentsebenziswano weii-amplifier zedijithalikwayeingcali izixhobo zokukhulisaiqinisekisa ukuba amandla asebenzisa i-frequency ephantsi anokulawulwa ngokuchanekileyo endaweni yokwandiswa ngokungaboniyo, nto leyo engundoqo ekufumaneni i-frequency ephantsi ecacileyo kwiindawo ezincinci.

Ulawulo lokuvumelanisa inqanaba le-millisecond lweamandlai-sequencerisombulula ingxaki yesigaba kwiindawo ezincinci. Ngenxa yobukhulu obuncinci begumbi, umahluko wexesha phakathi kwesandi esithe ngqo nesandi esibonakalayo mfutshane kakhulu, kwaye ulungiselelo lokulibaziseka olungafanelekanga lunokukhokelela ekurhoxisweni okukhulu kwesigaba.amandlai-sequencer iqinisekisa ukuhambelana ngokuchanekileyo kweisandisixesha lokuvelisa phakathi kweyona nto iphambiliisithethikunye ne-subwoofer, evumela isandi sebhendi nganye yefrikhwensi ukuba ifikelele kwindawo yokumamela ngaxeshanye. Esi sisiseko sobugcisa sokufumana amaza aphantsi acacileyo nancinci.

Intshayelelo kakrelekreleumxube wesandiyenze ulawulo lwesinema yesithuba esincinci lube lula ngakumbi kunangaphambili. Uhlengahlengiso lweparamitha oluntsonkothileyo lwendabuko luye lwenziwa lula kwiindlela zescene eziqondakalayo: imo ye-"action blockbuster" iphucula impembelelo enamandla yeefrikhwensi eziphantsi ezidlulayo, imo ye-"music appreciation" igxile ekuthambekeni nasekulandeleni kwefrikhwensi eziphantsi, kwaye "imo yasebusuku" igcina uluhlu oluguquguqukayo lweefrikhwensi eziphantsi ngelixa inciphisa ivolumu iyonke. Abasebenzisi banokutshintsha ngokulula kwi-interface ekrelekrele, kwayeiprosesas ngasemva kwayo kuza ngokuzenzekelayo uhlengahlengiso oluchanekileyo lweeparameter ezininzi.

Okuqhubekayoukubeka esweniyokulinganisa iimayikrofoni inika ithuba lokwenza inkqubo ibe ngcono ngokuguquguqukayo. Imayikrofoni yokujonga okusingqongileyo exhotyiswe kwiinkqubo zesinema zanamhlanje inokulandelela utshintsho lwe-acoustic ngexesha langempela kwigumbi - xa ifenitshala yangaphakathi ishukuma okanye abasebenzi benyuka okanye behla, inkqubo iya kuphinda ibuyele ngokuzenzekelayoisetiiimpawu zokuphuma kwe-subwoofer. Impembelelo yotshintsho lobushushu kunye nokufuma kwisantya sesandi nayo iya kuhlawulwa ngexesha langempela ukuqinisekisa ukusebenza okuhlala ixesha elide kokulungiswa kwe-acoustic.

Iinkqubo zesandi zobungcali ezikumgangatho ophezulubabonisa ixabiso labo elibalaseleyo kwinqanaba lokugqibela lokwenza ngcono isithuba. Xa i-subwoofer idityaniswe ngokugqibeleleyo neisithethi esiphambili, yonkeintsimi yesandiinika ukuhambelana okumangalisayo – nokuba ziifrikhwensi ezisezantsi ezinzulu ezigqunywe yimingxuma emnyama kwi-Interstellar okanye amaza esandi acinezelayo eejethi zokulwa ezintywila eDunkirk, zinokuphinda zivele ngokuchanekileyo kwindawo encinci kwinqanaba le-cinema.imakrofoni engenazingcingoIxhotyiswe kwinkqubo ayisetyenziselwa kuphela ukulawula ilizwi imihla ngemihla, kodwa ikwadlala indima ephambili ekulinganisweni kwelizwi ngokuzenzekelayo: abasebenzisi kufuneka babambe imakrofoni engenazingcingo baze bayihambise kwindawo yokumamela, kwaye inkqubo inokugqiba ngokuzenzekelayo ukulinganisa amanqaku amaninzi kwaye ilungise ngobuchule iiparameter zebhalansi yebhendi nganye yefrikhwensi. Olu hlengahlengiso "olungenangqiqo" luvumela abathengi abaqhelekileyo ukuba bafumane ngokulula isiphumo esigqibeleleyo esilungisiweyo ziingcali ze-acoustic.

Ngamafutshane, ukwenziwa ngcono kweendawo ezincinci zemiboniso bhanyabhanya yanamhlanje kuye kwavela ekubeni yingqokelela yezixhobo ezilula ukuya kwinkqubo epheleleyo yesayensi edibanisaisandi sobungcali esikumgangatho ophezului-hardware, ulawulo lwe-subwoofer olukrelekrele, umqhubi ochanekileyo wee-amplifiers zobungcali, ukuguqulwa okusebenzayo kwee-amplifiers zedijithali, ukulungiswa kwe-algorithm yeprosesa, ukuvumelanisa okuchanekileyo kweamandlaii-sequencers, kunye nokulinganisa okukrelekrele kweimakrofoni engenazingcingoLe ndlela yokutshintsha indawo ayisombululi nje kuphela imida ye-acoustic yamagumbi amancinci, kodwa ikwafaka namathuba angenamkhawulo e-acoustic kwiindawo ezilinganiselweyo ngetekhnoloji ekrelekrele. Kubalulekile ukukhankanya ukuba imakrofoni engenazingcingo exhotyiswe kwinkqubo yenza lula inkqubo yokusebenza ngelixa iqinisekisa ubungcali kunye nokuchaneka kokulinganiswa - abasebenzisi banokufumana iziphumo eziphuculweyo ngokubala ngokuchanekileyo ngemisebenzi elula, befezekisa ngokwenene ulungelelwaniso olugqibeleleyo phakathi kwetekhnoloji yobungcali kunye namava omsebenzisi. Ivumela yonke intsapho ukuba ifumane isandi esinyukayo kunye nemvakalelo yokuntywila efana neebhanyabhanya zobungcali kwindawo elinganiselweyo, igqibezela inqanaba elisemgangathweni ukusuka "kokuvakalayo" ukuya "kokuthusayo".
