Yiyiphi i-Surround Sound
Izwi elizungezile liyigama elisetshenziselwa izinhlobo eziningana zefomethi ezenza umlaleli azwe umsindo ovela ezikhombini eziningi, kuye ngokuthi indaba yomthombo.
Kusukela maphakathi no-1990 ukuzungezile kuzungeze kube yingxenye ebalulekile yokuhlangenwe nakho kwendlu yaseshashalazini, futhi, ngaleyo ndlela, kuye kwafika umlando wezingqikithi zomsindo ozungezile ongakhetha kuwo.
Abadlali ku-Surround Sound Landscape
Abadlali abakhulu kumhlaba ozwakalayo we-surroundings yi-Dolby ne-DTS, kodwa kubekhona / futhi abanye, njenge-Auro Audio Technologies. Futhi cishe wonke umenzi wemikhiqizo yemidlalo yaseshashalazini, ngokufaka phakathi kokufaka ubuchwepheshe ngenye eyodwa noma ngaphezulu kulawo makampani, futhi banikela ngezindlela zabo ezengeziwe zokuthuthukisa ukuhlangabezana nesipiliyoni esizungezile.
Okudingayo Ukufinyelela Umsindo Okuzungezile
Ukuze uzwe umsindo ozwakalayo, udinga isamukeli semidlalo yaseshashalazi ehambisanayo esekelwe isimiso sesiphakamiso sesiteshi sesiteshi esingu-5.1 , isampuli se-AV / isishushini esibanjwe nge-multi-channel amplifier kanye nezipikhethi, uhlelo lweseshashalazi-in-a-box, noma ibha yomsindo.
Noma kunjalo, inombolo nenhlobo yezikhulumi, noma ibha yomsindo, onayo ekusetheleni kwakho ingxenye eyodwa kuphela ye-equation. Ukuze uthole inzuzo yomsindo ozungezile, udinga ukufinyelela okuqukethwe komsindo ukuthi isamukeli sekhaya yakho yaseshashalazini, noma enye idivaysi ehambisanayo, inamandla okwenza noma ukucubungula. Lokhu kungenziwa ngezindlela eziningana.
Vumelanisa Ukumiswa Kwemisindo
Enye indlela yokufinyelela umsindo ozungezayo nge-inqubo yokufaka ikhodi / yokukhipha ikhodi. Le ndlela idinga ukuthi isignali yomsindo ozungezile ixutshwe, ifakwe ikhodi, ibekwe kwiDis noma ifayela lokulalelwayo elikwazi ukusakaza, ngomhlinzeki wokuqukethwe (njenge-studio ye-movie). Isignali yomsindo ozungezile kufanele ifundwe ngedivayisi yokudlala ehambisanayo (Ultra HD Blu-ray, Blu-ray, DVD), noma umsakazo wezindaba (i-Roku Box, i-Amazon Fire, i-Chromecast).
Umdlali noma umsakazo usithumela isignali encoded nge-digital optical / coaxial noma i-HDMI uxhumano kumceiver yasekhaya, iprojector ye-AV, noma enye idivayisi ehambisanayo engakwazi ukucacisa isignali, futhi isakaze iziteshi ezifanele nezikhulumi ukuze zikwazi ukuzwakala ngumlaleli.
Izibonelo zezakhiwo ezizwakalayo ezizungezile eziwela kulo mkhakha zihlanganisa: i- Dolby Digital, i-Dol, 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 , ne- Auro 3D Audio .
Sondeza Ukucutshungulwa Kwemvelo
Enye indlela ongayifinyelela ngayo umsindo ozungezayo ngukucubungula umsindo ozungezile. Lokhu kuhlukile, kulokho nakuba udinga indawo yaseshashalazini yasekhaya, i-processor ye-AV, noma ibha yomsindo ukuyifinyelela, ayidingi noma iyiphi inqubo ekhethiwe yokufaka ikhodi ekugcineni.
Esikhundleni salokho, ukucubungula umsindo okuzungezile kufezwa yi-receiver yemidlalo yasendlini (njll ...) ukufunda isignali yomsindo engenayo (okungaba isilwane noma idijithali) bese ubheka iziqephu ezivele zifakiwe ezinikezela inkomba lapho lezo zomsindo zingafakwa khona uma babenomfomfomu ozwakalayo ohambelana nendawo.
Nakuba imiphumela ayiyona enembile njengokuzungezile okuzungezile esebenzisa isistimu yokufaka ikhodi / yokumisa ikhodi, okuqukethwe akuzange kube khona ngaphambili kuzungeze umsindo oqoshiwe.
Okumnandi ngale mqondo ukuthi ungathatha isignali ye-stereo yesiteshi ezimbili futhi "upmix" kumashaneli angu-4, 5, 7, noma ngaphezulu, kuye ngokuthi ifomethi yokucubungula imisindo ejikelezayo isetshenziswe.
Uma uke wazibuza ukuthi yini amathebula wakho we-VHS Hifi endala, ama-Cassettes e-Audio, ama-CD, ama-Vinyl Amarekhodi, ngisho nokusakazwa kwe-FM stereo umsindo njengomsindo ozungezile, ukucubungula umsindo we-surroundings kuyindlela yokukwenza.
Amanye amafomethi okucubungula umsindo ahlanganisiwe kuma-receiver amaningi asekhaya, nakwamanye amadivaysi ahambisanayo, afaka i-Dolby Pro-Logic (kuze kube ku-4 iziteshi), i-Pro-Logic II (kuze kube ku-5 iziteshi), i-IIx (ingakhuphula umsindo we-channel wesiteshi 2 kuya eziteshini ezingu-7 noma, iziteshi ezingu-5.1 ezikhokhelwe isiteshi kuze kufike ku-7.1 iziteshi), ne-Dolby Surround Upmixer (okungaphakamisa iziteshi ezivela ku-2, 5, noma ku-7 ezenzakalweni ezizungezile ze-Dolby Amosi ngeziteshi ezimbili noma ngaphezulu).
Ehlangothini lwe-DTS, kune- DTS Neo: 6 (ingaxhuma iziteshi ezimbili noma ezi-5 eziteshini ezingu-6), i- DTS Neo: X (iyakwazi ukuphakamisa iziteshi ezingu-11, 5, noma iziteshi ezingu-7 ku-11.1 iziteshi), i-DTS Neural: X (imisebenzi ngendlela efanayo neDolby Atmos upmixer).
Amanye amamodi wokucubungula okuzungezile ahlanganisa i- Audyssey DSX (ingakwazi ukwandisa isignali esakhiwe ngesiteshi esingu-5.1 ngokungeza kokubili isiteshi esikhulu esengeziwe noma isiteshi sokuphakama ngaphambili noma kokubili.
Futhi, i-Auro 3D Technologies iphinda itholakale ifomethi yayo yokucubungula umsindo esebenza ngendlela efanayo neDolby Surround ne-DTS Neural: X upmixers.
Ngisho ne-THX inikeza izindlela zokuzungezisa umsindo ezizungezile ezenzelwe ukwandisa isipiliyoni sekhaya sokulalela ama-movie, imidlalo, nomculo.
Njengoba ubona ukuthi kuningi lokuzwakalisa umsindo ozungezile kanye nezinketho zokucubungula ezitholakalayo, kuye ngokuthi umkhiqizo / imodeli yamukeli wendawo yaseshashalazini, i-processor ye-AV, noma ibha yomsindo, kodwa akuyona yonke into.
Ngaphandle kokumemezela umsindo okuzungezile nokucubungula amafomethi ngenhla, abanye abamukelayo yaseshashalazini ekhaya, abacwaningi be-AV, nabenzi be-sound bar bengezela ukunambitheka kwabo namafomethi afana ne-Anthem Logic (Anthem AV) neCinema DSP (Yamaha).
Virtual Surround
Ngenkathi ama-decoding ezungezwe ngenhla kanye namafomethi okucubungula asebenza kahle kumahlelo anezikhulumi eziningi, okuhlukile okudingeka kusetshenziswe ngeBrave Sound - yilapho umsindo ozwakalayo ozungezayo ungena khona. Izwi elizungezile elizungezile lenza ibha yomsindo, noma olunye uhlelo (ngezinye izikhathi lunikezwe i-home receiver receiver njengenye indlela) enikeza "umsindo ozungezayo" ukulalela izikhulumi ezimbili kuphela (noma izikhulumi ezimbili ne-subwoofer).
Eyaziwa ngamagama amaningana (kuye ngokuthi umshini we-sound bar) Isigaba Cue (Zvox), Circle Surround (i-SRS / DTS - Circle Surround ingasebenzisa kokubili imithombo engabhalisiwe nekhodiwe), i-S-Force Front Surround (Sony), i-AirSurround Xtreme (i-Yamaha ), kanye no-Dolby Virtual Somlomo (i-Dolby), indawo engezansi akuyona neze umsindo weqiniso okuzungezile nhlobo, kodwa iqembu lobuchwepheshe ukuthi, ngokusebenzisa isigaba sokuguquguquka, ukulibaziseka komsindo, ukuzindla komsindo nezinye izinqubo, ukuzama ukuzwa bahlangabezana umsindo ozungezile.
Isizungezo esibukeka singasebenza ngenye yezindlela ezimbili, kungase kuthathe isignali esinesiteshi ezimbili futhi unikeze ukwelashwa okufana nomsindo, noma kungathatha isignali yesiteshi esingaphakathi 5.1, ukuyixuba ngeziteshi ezimbili, bese usebenzisa lezo zigcawu ukunikeza isipiliyoni somsindo ozungezile usebenzisa izikhulumi ezimbili ezitholakalayo okufanele zisebenze nazo.
Enye into ethakazelisayo mayelana nezwi le-Virtual Surround yilokho elingasetshenziswa ukunikeza isipiliyoni esizwakalayo sokulalela esimweni sokulalela umakhalekhukhwini. Izibonelo ezimbili yi-Yamaha Silent Cinema, ne-Dolby Headphone.
Ukuthuthukiswa kobumnyama
Izwi elizungezile lingagcwaliswa ngokuqhubeka nokusetshenziswa kwe-Ambience Improvement. Ezimweni eziningi zokuthola izakhiwo zasendlini, izilungiselelo ezithuthukisiwe zomsindo ezengeziwe zinikezwa ukuthi zingangeza ambience ukuzungeze ukulalela okuzwakalayo, kungakhathaliseki ukuthi okuqukethwe komthombo kunqunywe noma kusetshenzwe.
Ukuthuthukiswa kwe-ambience kusuka ekusetshenzisweni kweReverb ukulinganisa indawo enkulu yokulalela emuva kuma-60 no-70's (asetshenziswe okuningi emotweni yemoto), kodwa ngokungaqondile, njengoba isetshenziswe ngaleso sikhathi, ingabacasula kakhulu.
Kodwa-ke, indlela okuqukethwe kwe-reverb okusetshenziselwa ngayo lezi zinsuku, ngezindlela zomsindo noma zokulalela ezinikezwe kumamukeli amaningi asethempelini yaseshashalazini ne-AV processors. Lezi zindlela zengeza ama-ambience ambalwa okumele afakwe ezinhlotsheni ezithile zokucuketfwe noma ukulinganisa indawo ye-ambience ne-acoustic yezindawo ezithile zegumbi.
Isibonelo, kungase kube khona izindlela zokulalela ezihlinzekwe nge-Movie, Music, Game, noma ezemidlalo okuqukethwe - futhi, kwezinye izimo ithola okucacile kakhulu (i-Sci-Fi movie, i-Adventure Movie, i-Jazz, i-Rock, njll ...).
Noma kunjalo, kukhona okuningi. Abanye abamukelayo yaseshashalazini basekhaya bahlanganisa nezilungiselelo ezifanisa ama-acoustics ekwakhiweni kwekamelo, njenge-Movie Theater, Auditorium, Arena, noma iSonto.
Ukuthinta kokugcina okutholakala kulabo abamukeli bezindawo zaseshashalazini eziphezulu, ikhono labasebenzisi ukuqhubekela phambili ukuhlela imodi yokulalela yokubeka kuqala / izilungiselelo zesimanje ngesandla ukuze unikeze imiphumela engcono ngokulungisa izinto ezifana nobukhulu bendawo, ukubambezeleka, ukukhathazeka, kanye isikhathi sokuphindaphinda.
Okubalulekile
Njengoba ubona, i-Surround Sound ingaphezu kwenkulumo yokubamba. Kuye okuqukethwe kwakho okukhona, idivayisi yokudlala, nezici zamakamelo, kunezinketho eziningi zokulalela ezingatholakala futhi zihambisana nezidingo zakho nezintandokazi zakho.
