Riaan Ukuqonda ithrendi yakamuva (noma i-gimmick) kumsindo.
Umsindo we-Spacial uhumusha umsindo ozungezile kuma-headphone nezipikha. Inikeza umuzwa womsindo we-“3D” ogxilile wamamuvi noma umculo, futhi kunemikhiqizo eminingi engeyona eye-Apple engasebenzisa ubuchwepheshe.
Kubonakala sengathi wonke umkhiqizo omusha womsindo unikeza “umsindo wendawo,” ubuchwepheshe obuthole ukunakwa okuningi ngenxa ye-Apple. Kodwa umsindo we-spacial usazwakala ungaqondakali futhi uyadida. Ngakho-ke, yisikhathi sezimpendulo eziqondile-nansi incazelo egcwele yomsindo we-space kanye nehadiwe edingekayo ukuze uyijabulele.
I-Spatial Audio iyizwi lokulalela “eligxilile”
Uma uya ethiyetha ye-movie ehloniphekile, uzobona ukuthi umsindo uvela kuzo zonke izinhlangothi—imisindo ingase ibe kwesokunxele noma kwesokudla sakho, kodwa ingase ivele ngemuva noma ngaphezu kwekhanda lakho. Amatiyetha asebenzisa amafomethi omsindo azungezile afana ne-Dolby Atmos ukuze afinyelele lo muzwa womsindo ofana nempilo, nakuba amafomethi anjalo adinga izipikha eziningi ezibekwe zizungeze igumbi lonke.
Ungakha uhlelo lwe-Dolby Atmos ekhaya (futhi abantu abaningi bayakwenza). Kodwa kuwumsebenzi obizayo, futhi emakamelweni amaningi, kuwukuphazamiseka okuphelele. Ngakho-ke, izinkampani ezimbalwa zakha amafomethi “omsindo wendawo”, elingisa umsindo ozungezile zisebenzisa ama-headphones endabuko kanye nezinhlelo zesipikha se-stereo.
Kunamafomethi womsindo wendawo amaningana ahlukene. I-Apple Spatial Audio yiyona eyaziwa kakhulu, kodwa kukhona ne-Sony 360 Reality Audio, i-THX Spatial Audio, ne-DTS:X, phakathi kokunye. Ukuqaliswa okungeziwe komsindo wendawo kuzofika nakanjani eminyakeni ezayo.
Wonke lawa mafomethi athembisa ukuletha umsindo ozwakalayo ozungezile ngaphandle kwesistimu yesipikha esingcolile. Sekushiwo lokho, amanye amafomethi (okuhlanganisa ne-Apple) nawo alandelela ikhanda lakho ukuze alingise umuzwa wokuba segumbini elinezipikha zangempela. Ngokombono, umsindo wendawo onokulandelwa kwekhanda kufanele uzizwe “ungokwemvelo” ngokwengeziwe lapho ubuka amafilimu, futhi kufanele kukunikeze umbono wokuthi “usestudiyo” noma “usendaweni” lapho ufaka ohlwini lomculo—lokhu kuncike ngokuphelele, kunjalo.
Isebenza Kanjani I-Spatial Audio?
Wonke amafomethi omsindo wendawo asebenza ngendlela efanayo eyisisekelo. Bathatha umsindo ozwakalayo wangempela ozungezile, ongahle uhloselwe isistimu yesipikha sesiteshi esingu-5.1- noma 7.1, bese uwenza into engadlala ngama-headphone noma izipikha zesitiriyo sosiko.
Isofthiwe yobunikazi isetshenziselwa ukulondoloza umphumela “womsindo ozungezile” walo msindo weziteshi eziningi. Ngakho-ke, nakuba umsindo wendawo unjalo ngokobuchwepheshe 2-iziteshi stereo, kuzwakala sengathi umsindo uvela kuzo zonke izindawo. Indiza ekwimuvi ingase izwakale sengathi ingaphezu kwekhanda lakho, futhi uma ulalele umculo ngomsindo wendawo, kungase kubonakale sengathi izinsimbi noma ukuduma kwegumbi kusemva kwakho.
Amamuvi amaningi nezinhlelo ze-TV zitholakala kalula e-Dolby Atmos. Futhi uma umculi efuna ukukhipha umculo ngomsindo ozungezile, i-Dolby Atmos ivamise ukuba yifomethi ekhethwayo. Ngakho-ke, iningi lezinhlelo zokulalelwayo zendawo, kufaka phakathi i-Apple, imane idinga inkosi ye-Dolby Atmos. Isofthiwe ezenzakalelayo ingenza wonke umsebenzi, nakuba ezinye izitudiyo zizocubungula ngomphathi wazo womsindo ozungezile ukuze zithole okuphuma phambili komsindo wendawo.
Uma isistimu yomsindo yendawo inikeza ukulandelela kwekhanda, ngokuvamile kufinyelelwa nge-gyroscope, ikhamera, noma inhlanganisela yakho kokubili. Lesi sici sitholakala kuma-headphones kuphela, kodwa njenge ubuchwepheshe be-beamforming kuyathuthuka, ngiqinisekile ukuthi ukulandelela ikhanda kuzoba ingxenye yezinhlelo zesipikha somsindo wendawo.
Kufanele ngiqaphele ukuthi ukwenza i-audio beamforming, ubuchwepheshe obulawula indlela umsindo ohamba ngayo emkhathini, sebuvele busetshenziswa kwezinye izipikha zomsindo zezikhala. I-HomePod yakwa-Apple isebenzisa i-beamforming ukukala ama-acoustics egumbi futhi ilungise umsindo wayo ngokufanele—lokhu kusiza isipika ukuthi silethe ikhwalithi yomsindo engcono kakhulu engenzeka, kodwa futhi kuqinisekisa ukuthi ama-HomePod amabili angaletha umuzwa oqinile womsindo wendawo lapho ebhangqwe ndawonye.
Yini oyidingayo Ngomsindo Wendawo?
Isofthiwe ye-Spatial audio idinga inani elihloniphekile lamandla okuhlanganisa, ikakhulukazi uma ukulandelwa kwekhanda kuhilelekile. Futhi, ukuhluka kosayizi wesipikha noma ibanga kungalimaza “umphumela we-3D” womsindo wendawo, njengoba ukucubungula isofthiwe kudinga ukunemba kahle.
Ngenxa yalezi zingqinamba, kunzima ukuthola umuzwa womsindo wendawo ohlanganisa yonke indawo ngaphandle kwama-headphones noma izipikha ezakhelwe inhloso. Kukhona okuhlukile—i-Apple Music ikuvumela ukuthi uzwe umsindo wendawo (ngaphandle kokulandelela ikhanda) kunoma yimaphi ama-headphone amadala, inqobo nje uma ungumnikazi wedivayisi yokudlala ehambisanayo. Kepha i-Apple Music ihlukile kulo mthetho.
Uma ufuna ukuzwa umsindo wendawo ku-Netflix, i-Amazon Video, i-Tidal, noma ezinye izinkundla eziningi ezinikeza umsindo we-Dolby Atmos, udinga i-hardware eyakhelwe inhloso. Ngokukhethekile, udinga ama-headphone, ama-earbud, izipikha, noma ibha yomsindo enikeza ngokusobala okuphumayo komsindo wendawo (noma okwenziwe nge-Dolby Atmos).
Lezi zisetshenziswa ezakhelwe inhloso zivame ukuqukatha ama-chip akhethekile ekhompiyutha. Futhi izipikha zomsindo wendawo cishe zihlala zinedizayini evalekile, okusho ukuthi bonke abashayeli bezipikha banamathele ngaphakathi kwepulastiki enkulu (cabanga ngebha yomsindo noma i-HomePod). Lokhu kukuvimbela ekuguquleni ibanga phakathi kwezishayeli zezipikha, okungase kuthinte ikhwalithi yomsindo. (Sekushiwo lokho, akuvamile ukuthi ama-AVR anikeze izinga elithile le-Dolby Atmos virtualization. Kodwa ama-AVR angaphandle kwendawo yalesi sihloko.)
Labo abafuna ukunamathela imikhiqizo Apple bangakhetha kusuka I-AirPods Pro, I-AirPods Maxfuthi I-Beats Fit Pro. Ungakwazi futhi ukuzwa umsindo we-spacial nge-Google I-Pixel Buds ProSony I-WH-1000XM5 futhi I-WF-1000XM4futhi uma ungumdlali wegeyimu, iningi Amahedisethi eRazer izokwenza umsebenzi wenziwe (nge-THX Spacial Audio, uRazer engumnikazi wayo).
Akuvamile ukuthi ama-soundbar anikeze umsindo we-spacial (nge-DTS Virtual:X). Ibha yomsindo ka-Vizio ye-M-Series kuyindlela enhle eshibhile, nakuba kukhona futhi Ibha ye-JBL, I-Polk Signa S4futhi I-Sonos Arc. Ngokuqondene nezipikha ezizimele, izinketho ezihlakaniphile ezifana ne I-HomePod futhi I-Echo Studio ngokuvamile inketho yakho engcono kakhulu, nakuba futhi ngiphakamisa ukubheka ku I-Sonos Era 300. (Zonke ezintathu zalezi zipikha zingahlanganisa nesistimu yetiyetha yasekhaya, ngendlela.)
Ingabe I-Spatial Audio Ilungile, Noma Ingabe I-Gimmick Nje?
Umculo uhlale uyindaba yokunambitha. Abanye abantu bazojabulela umsindo we-spacial, kanti abanye ngeke. Futhi kunendawo empunga eningi lapha—lonke uhlobo lunokuqaliswa okuyingqayizivele komsindo we-spacial, futhi ngokuhlangenwe nakho kwami, isici sizwakala sihluke kakhulu kusipika kunokuba sizwakala kuma-headphones.
Enye yezinto ezinzima mayelana nomsindo we-spacial, nomsindo ozungezile ngokujwayelekile, ukuthi akukwazi ukucatshangelwa kamuva. Izitudiyo zama-movie ne-TV ziyazi ukuthi okuqukethwe kwazo kuzoxutshwa futhi kwenziwe kahle ku-Dolby Atmos, ngakho zisebenzisa imakrofoni namasu akhethekile phakathi nenqubo yokurekhoda. Kodwa lokhu akuvamile ukuba kube njalo ngesikhathi sokurekhoda komculo, futhi ngenxa yalokho, umculo ozungezile ungashaywa kakhulu noma ungaphuthelwa.
Abantu abaningi bazoqale bahlangane nomsindo we-spacial lapho belalele umculo (okungenani, lokhu kuzoba ukuhlangana kwabo kokuqala kokwazi). Uma bezonda ukuthi kuzwakala kanjani, bazobhala ngokushesha ubuchwepheshe njenge-gimmick eyisiphukuphuku, engalungile kakhulu. Ngiphakamisa ngokuqinile ukuhlola umsindo we-spacial ngamamuvi nezinhlelo ze-TV, lapho unendawo enkulu yokukhanya.
Ngokuqondene nombono wami siqu, ngikholelwa ukuthi umsindo we-spacial uyi-gimmick. Kodwa i-gimmick encane ejabulisayo. Angiwuboni umonakalo kubuchwepheshe, futhi bunginika indlela entsha yokuzwa izingoma zami eziyintandokazi namamuvi. Ngicabanga futhi ukuthi umsindo wendawo uzothuthuka ngokuhamba kwesikhathi, njengoba ngibone ukuthuthuka okuningi ku-DTS: X ama-soundbars eminyakeni edlule.
