Yisiphi Isandi seNgcaciso
Isandi esijikelezayo sisigama esisetyenzisiweyo kwiintlobo ezininzi zeefom ezenza ukuba umphulaphuli abe nesandi esivela kwiinkalo ezininzi, kuxhomekeke kwimithombo yendalo.
Ukusukela phakathi ko-1990 ukuzungeze i-sound surround has been a part of the experience of theater home, kwaye, kunye naloo nto, kuye kwavela imbali yeefomathi ezizungezile ezikhethiweyo ukuba zikhethe.
Abadlali kwi-Surround Sound Landscape
Abadlali abaphambili kwimihlaba engqongekileyo yi-Dolby kunye ne-DTS, kodwa kubekho / kunye nabanye, njenge-Auro Audio Technologies. Kwakhona nje malunga nomenzi we-receiver receptionist yasekhaya, ukongezelela kubandakanya ubuchwephesha ngabanye okanye ngaphezulu kwale nkampani, nabo banikezela iinguqu zabo ezongezelelweyo ukuphucula amava angqongileyo.
Okukufunayo Ukufikelela kwiSandi seNdlebe
Ukufumana isandi esicacileyo, udinga i- receiver ye-homeater reception ehambelana nesistim somnxeba we-5.1 , isitampu se-AV / iprojista ehambelana ne-amplifier yamashishini kunye nezithethi, i-home-in-a-box system, okanye ibha yesandi.
Nangona kunjalo, inombolo kunye nohlobo lwezithethi, okanye ibha yomsindo, unayo ekusetyenzisweni kwakho yinxalenye enye ye-equation. Ukuze ufumane inzuzo yomsindo ojikelezayo, kufuneka kwakhona ufikelele kumxholo womculo ukuba umkeli wakho wendawo yemidlalo, okanye esinye isixhobo esihambelanayo, unokukwazi ukuhlaziya okanye ukwenza inkqubo. Oku kungenziwa ngeendlela ezininzi.
Ukuhlaziywa kweNgcaciso yeNdlebe
Enye indlela yokufikelela kwisandi esingqongileyo ihamba ngekhowudi yokudibanisa / yokuqulunqa. Le ndlela idinga ukuba isalathisi esizungezile sixutywe, sifakwe ngekhowudi, kwaye sibekwe kwiDisk okanye ifowuni yomsindo we-audio, ngumniki-nkonzo (njengesikripthi se-movie). Isibonakaliso esilungekileyo esisekhompyutheni sifanele sifunde kwisixhobo sokudlala esifanelekileyo (i-Ultra HD Blu-ray, i-Blu-ray, i-DVD), okanye umsakazo weendaba (i-Roku Box, i-Amazon Fire, i-Chromecast).
Umdlali okanye umgcini-thumela ke uthumele isalathisi esicatshulwa nge-digital optical / coaxial okanye i-HDMI uxhumano kwi-home receiver receiver, AV processor proser, okanye enye ifowuni ehambelana nayo leyo inokwenza isigqibo, kwaye isasaze kwizithuba ezifanelekileyo kunye nezithethi ukuze kuvezwa ngumphulaphuli.
Imizekelo yefomathi ezivakalayo ezizungezile eziwela kule nqanaba ziquka: i- Dolby Digital, i-EX, i-Dolby Digital Plus , i- Dolby TrueHD , i- Dolby Atmos , i- DTS Digital Surround , i- DTS 92/24 , i- DTS-ES , i- DTS-HD i-Master Audio , i- DTS: X , kunye neAuro 3D Audio .
UkuPhathwa kweeNdlebe
Enye indlela ongayifumana ngayo isandi esingqongileyo sithengiswa ngokusingqongileyo. Oku kuhlukile, ukuba nangona ufuna i-homeater yaseshashalazini, iprogram ye-AV, okanye ibha yesandi ukufikelela kuyo, ayifuni nayiphi na inkqubo ekhethiweyo yokudibanisa ekupheleni.
Esikhundleni salo, ukucwangciswa kwezandi ezizungezile kufezwa ngumkeli womdlalo wekhaya (njl ...) ufunda isignali yomsindo engenayo (enokuthi i-analog okanye idijithali) kwaye ukhangele izikhombo ezifakwe ngaphakathi ezibonelela ukuba kukho izandi ukuba zibekwe ukuba babenomxholo ozwakalayo obhalwe ngekhowudi.
Nangona iziphumo azikho ezichanekileyo njengendawo ejikelezileyo ejikeleza inkqubo esebenzisa ikhodi yokudibanisa / yokuhlaziya, umxholo awungekho udibanise i-sound encoded ngaphambili.
Yintoni efanelekileyo malunga nale ngcamango kukuba ungathatha nayiphi na isignali ye-stereo yesignali kwaye "uphakamise" kwii-4, 5, 7, okanye ezinye iziteshi, ngokuxhomekeke kwifomathi yokusetyenziswa kweefayile ezijikelezayo.
Ukuba uke wazibuza ukuba yeyiphi iifowuni zeVHS zeHS zokudala, iiCapesettes eziVakalayo, iiCD, iiRekodi zeVinyl, kunye nee-FM stereo zisasaza ngathi zisesandi esizungezile, ukucutshungulwa kwezandi ezizungezile yindlela yokuyenza.
Ezinye iifom zendlela yokucoca izandi ezifakwe kwiindawo ezininzi zokufumana izakhiwo zasekhaya, kunye nezinye iifowuni ezihambelanayo, ziquka i-Dolby Pro-Logic (ukuya kwii-4 iziteshi), i-Pro-Logic II (ukuya kuma-5), iix ukuya kumashishini angama-7 okanye, ama-5.1 ekhompyutheni angena kwii-7.1 iziteshi), kunye neDolby Surround Upmixer (enokuxubusha kwii-2, 5, okanye ezise-7 ukuya kwi-Dolby uAsmos-like experience experience with two or vertical channels).
Kwinqanaba le-DTS, kukho i- DTS Neo: 6 (inokuxubusha iziteshi ezimbini okanye ama-5 kumashishini angama-6), i- DTS Neo: X (iyakwazi ukuphakamisa iziteshi ezi-11.1), i-DTS Neural: X (leyo imisebenzi ngendlela efanayo neDolby Atmos upmixer).
Ezinye iindlela ezizungezile zendlela yokucwangcisa izandi ziquka i- Audyssey DSX (inokwandisa isignali echazwe ngesitishi esingu-5.1 ngokungongeza zombini ishaneli ebanzi okanye isiteshi sokuphakama esiphezulu okanye zombini.
Kwakhona, i-Auro 3D Technologies yenza ukuba kufumaneke ifomathi yokucoca ngomculo esebenza ngendlela efanayo neDolby Surround kunye ne-DTS Neural: X mix mixers.
Nangona i-THX inikela ngeendlela zokucwangcisa izandi ezizungezile ezenzelwe ukwandisa amava okulalela ama-movie, imidlalo kunye nomculo.
Njengoko ubona ukuba kukho inqwaba ye-decoding sound surroundings kunye neendlela zokucwangcisa ezikhoyo, ngokuxhomekeka kwitshati / imodeli yomkeli wekhamera yasekhaya, i-processor ye-AV, okanye ibha yesandi, kodwa akusiyo yonke into.
Ukongeza kwi-ecoding sound surroundings kunye neefomati zokucwangcisa ngaphezulu, ezinye i-home receivers receivers, abaprojekthi ze-AV, kunye nabenzi be-bar bar add their flavour their formats ezifana ne-Anthem Logic (i-Anthem AV) kunye neCinema DSP (Yamaha).
Ngqonge
Ngethuba le ngentla ingqonge i-decoding kunye nefomathi yokusebenza isebenza kakuhle kwiinkqubo ezineentetho ezininzi, into eyahlukileyo ifanele iqeshwe ngeBhotile eziNgcono - yiyo apho i-sound surround surround. i-home receiver receiver njengenye indlela) enika "i-surround sound" ukuphulaphula izithethi ezimbini (okanye ezimbini izithethi kunye ne-subwoofer).
Eyaziwayo ngamagama amaninzi (kuxhomekeke kumkhwa wesibrari sesandi) I-Phase Cue (Zvox), i-Circle Surround (i-SRS / DTS-Circle Surround inokusebenza kunye nemithombo engabikho ikhowudi kunye nekhowudi), i-S-Force Front Surround (i-Sony), i-AirSurround Xtreme (i-Yamaha ), kunye ne-Dolby Virtual Somlomo (i-Dolby), ingqonge engqinileyo yinyani kungekhona yinyani ejikelezileyo, kodwa iqela lobuchwephesha, ngokusebenzisa ukuchithwa kwesigaba, ukulibaziseka kwezandi, ukucinga okuvakalayo kunye nezinye iindlela, ukucinga ngeendlebe zakho bafumana isandi esingqongileyo.
Ingqonge engqinileyo inokusebenza ngenye yeendlela ezimbini, inokuthabatha isalathisi esinesibini kunye nokunika unyango olulungekileyo, okanye ungathatha isignali yesiteshi esingu-5.1, udibanise kumashishini amabini, uze usebenzise ezo zigcawu ukubonelela ngamava aphilileyo asebenzisa iisithethi ezimbini ezikhoyo kufuneka zisebenze nazo.
Enye into enomdla malunga neNkcazo ye-Virtual Surround yiyo ingasetyenziselwa ukubonelela ngamava aphulaphule ngokuphulaphulayo kwimeko yokulalela indlebe. Imizekelo emibini yi-Yamaha Silent Cinema, kunye ne-Dolby Headphone.
Ukuphuculwa kwamandla
Isandi esijikelezayo sisenokugqitywa ngokugqitywa kokuphunyezwa kweNtsebenzo yoLungiso. Kwiindawo ezininzi zokufumana izakhiwo zasekhaya, izicwangciso zokongeza izandi ezongezelelweyo zinikezelwa ukuba zingongeza i-ambience ukujikeleza ukuphulaphula okuvakalayo, ingaba umxholo womthombo uhlaziywa okanye uqhutywe.
Ukuphuculwa kwesimo sezulu kuyingcambu ekusetyenzisweni kweReverb ukulinganisa indawo enkulu yokuphulaphula emva kwee-60 kunye nee-70 (esetyenziswe ezininzi kwiimoto zomsindo), kodwa ngokunyanisekileyo, njengoko isetyenziswe ngelo xesha, inokukhathaza kakhulu.
Nangona kunjalo, indlela umxholo we-reverb uqaliswa ngayo le ntsuku, uhamba ngeendlela ezizandileyo okanye eziphulaphulayo ezinikezelwe kwiimvume ezininzi zee-home and processors. Iimodesi zongeza ezinye iingcamango ezinxulumene nazo ezifunekayo ezilungiselelwe iintlobo ezithile zomxholo okanye zifanise i-ambience kunye nempahla ye-acoustic yeendawo ezithile zendawo.
Umzekelo, kunokubekho iindlela zokuphulaphulwa ezibonelelwe kwi-Movie, Music, Game, okanye i-Sports content - kwaye kwezinye iimeko ithola ngakumbi ngakumbi (i-Sci-Fi movie, i-Adventure Movie, i-Jazz, iRwala, njl ...).
Nangona kunjalo, kukho ngaphezulu. Abanye abamkeli bemidlalo yaseshashalazini baquka izicwangciso ezifanisa i-acoustics kwiindawo zendawo, njenge-Movie Theatre, i-Auditorium, i-Arena, okanye iCawa.
Umgca wokugqibela okhoyo kwiindawo zokufumana i-home-end-home-end ephezulu, amandla abo abasebenzisi ukuqhubela phambili ukulungelelanisa imodeli yokumamela / izicwangciso ze-ambience ngesandla ukuze unikeze umphumo ongcono ngokulungisa izinto ezifana nobukhulu bendawo, ukulibaziseka, ukunyaniseka, kunye ixesha lexesha.
Ngaphantsi
Njengoko ubona, I-Surround Sound ayikho nje ibinzana lokubamba. Ngokuxhomekeke kumxholo wakho okhoyo, ukudlala idivayisi, kunye neempawu zendawo, kukho iindlela ezininzi zokuphulaphulwa ezinokufikelela kunye nezilungelelaniso zakho neemfuno zakho.
