Kusukela umsindo we-stereophonic wathandwa eminyakeni yama-50 umncintiswano ubelokhu usungula isipiliyoni esikhulu sokulalela ekhaya. Ngisho nangasemuva ngawo-1930, kwahlolwa izilingo zomsindo ozungezile. Ngo-1940, uWalt Disney wafaka ubuchwepheshe bakhe obuseduze bukaFantasound obuzungezile ukuze acwilise ngokuphelele izethameli kokubili ukuzwa okubukwayo nokulalelwayo kokuphumelela kwakhe kwemifanekiso, i- Fantasia .
Nakuba "i-Fantasy", kanye nezinye izivivinyo zakuqala ezakhiweni zobuchwepheshe obungezungezile azikwazanga ukuphinda ziphindwe emakhaya, okwakungalinganisanga ukufunwa ngabanjiniyela bokurekhoda kokubili umculo nefilimu ukuthuthukisa izinqubo ezizogcina zifake izakhiwo zomsindo ezizungezile ezitholakala emabhayisikobho asekhaya emhlabeni jikelele namuhla.
Sound Monophonic
Umsindo we-monophonic wuhlobo olulodwa lwesiteshi, olulodwa lwe-unidirectional yokukhiqiza umsindo. Zonke izakhi zokurekhoda umsindo ziqondiswa usebenzisa i-amplifier eyodwa nenhlanganisela yesipikha. Kungakhathaliseki ukuthi uhlala kuphi egumbini uzwa zonke izakhi zomsindo ngokulinganayo (ngaphandle kwahlukahluka kwendima ye-acoustic). Endlebeni, zonke izakhi zomsindo, izwi, izinsimbi, imiphumela, njll ... zivela zivela endaweni efanayo endaweni. Kunjengokungathi konke "kukhonjiswe" endaweni eyodwa. Uma uxhuma izipikha ezimbili ku-Monophonic amplifier, umsindo uzovela ukuze uqale endaweni eqondile phakathi kwezikhulumi ezimbili, ukudala isiteshi "phantom".
Umsindo we-stereophonic
Umsindo we-Stereophonic wuhlobo oluvulekile lokukhiqiza umsindo. Nakuba kungenakwenzeka ngokuphelele, imisindo ye-stereophonic ivumela umlaleli ukuba ahlangabezane nesimo sokuzwakala somsindo wokusebenza.
Inqubo ye-Stereophonic
Isici esiyinhloko somsindo we-stereophonic ukuhlukaniswa kwemisindo kuzo zonke iziteshi ezimbili. Imisindo eqoshiwe ixubene ngendlela yokuthi ezinye izakhi zihanjiswe ngakwesokunxele kwendlela yokubhala; abanye ngakwesokudla.
Omunye umphumela omuhle womsindo we-stereo wukuthi abalaleli bahlangabezana nokuhlelwa kwemisindo efanele ye-symphony orchestra okuqoshiwe, lapho imisindo evela kuzinsimbi ezehlukene ngokwemvelo isuka ezigabeni ezahlukene zesiteji. Noma kunjalo, izakhi ze-monophonic nazo zifakiwe. Ngokuxuba umsindo ovela ku-vocalist oholayo ebhentshini, kuzo zombili iziteshi, umculi wezwi ozwakalayo uhlabelela esiteshini se "phantom", phakathi kweziteshi ezingakwesokunxele nezingakwesokudla.
Ukulinganiselwa komsindo we-Stereo
Umsindo we-Stereophonic waba yimpumelelo yabathengi abangama-50 no-60 kodwa unomkhawulo. Amanye amarekhodi akhiphe umphumela "we-ping-pong" lapho ukuxubana kugcizelela umehluko eziteshini ezingakwesokunxele nakwesokudla kakhulu ngokuxuba okungekho okwenziwe kwezakhi " kumzila wesiteshi " esiphakathi . Futhi, noma ngabe umsindo wawuyiqiniso, ukungabi nolwazi lwe-ambiance, njenge-acoustics noma ezinye izakhi, ishiya umsindo we-Stereophonic "nomthelela odongeni" lapho yonke into ikushaya khona ngaphambili futhi ingekho umsindo wemvelo wezindlalelo zangasemuva noma ezinye izakhi ze-acoustic.
Umsindo we-Quadraphonic
Izinguquko ezimbili zenzeke ngasekupheleni kweminyaka yama-60 futhi ekuqaleni kweminyaka engu-70 ezazama ukulungisa ukulinganiselwa kwe-stereo. Umlayezo we-Four Channel Discrete and Quadraphonic.
Izinkinga Nge-Disc-Four Channel
Inkinga nge-Four Channel Discrete, lapho kudingwa khona ama-amplifiers amane (noma ama-stereo amabili) ukuze akhiqize umsindo, ukuthi kwakubiza kakhulu (lawa yizinsuku zeT Tubes ne-Transistors, hhayi ama-IC nama-Chips).

Iyakwazi ukuthatha umthombo wokufaka wesiteshi esingu-5.1 futhi ubuyekeze isipiliyoni somsindo ozungezile ngezipikha ezimbili kuphela. Ngaphezu kwalokho, ukuzwa okuzungezile kungaphinde kwandise izignali zomsindo ezicindezelwe ezimbili (ezifana ne-MP3) ukuze uthole ukuzwa okunjenge-surroundings like an experience.
I-SRS / DTS i-Tru-Surround ne-Tru-Surround XT
I-SRS Labs yenye inkampani ehlinzeka ngobuchwepheshe obusha obukwazi ukuthuthukisa isipiliyoni semidlalo yaseshashalazini (Qaphela: Ngomhla ka-Julayi 23, 2012, i-SRS Labs manje ingokomthetho njengengxenye ye-DTS ).
I-Tru-Surround inekhono lokuthatha imithombo eminingi enekhodi ekhonjiwe, njenge-Dolby Digital, futhi iveza umphumela ozungezile ngokusebenzisa izipikha ezimbili kuphela. Umphumela awukona othakazelisayo njenge-Dolby Digital 5.1 yangempela (imiphumela yangaphambili nangemuva emizungezweni iyamangalisa, kodwa imiphumela ejikelezayo engemuva iwela kancane, ngomqondo ukuthi ivela nje kuphela ukufika kwekhanda lakho kunokuba ibuye ngemuva ekamelweni). Kodwa-ke, nabathengi abaningi behluleka ukugcwalisa igumbi labo ngamazwi ayisithupha noma ayisikhombisa, i-Tru-Surround ne-Tru-SurroundXT inikeza ikhono lokujabulela umsindo wesiteshi esingu-5.1 ngaphakathi kwendawo evamile yokulalela isiteshi.
I-SRS / DTS Circle Surround no Circle Surround II
Ngakolunye uhlangothi, umbuthano uzungeze umsindo ozungezile ngendlela ehlukile. Ngenkathi uhlelo lweDolby Digital ne-DTS luzungezile umsindo wokukhomba okuqondile (imisindo ethile evela ezikhulwini ezithile), Umjikelezo Surround ugcizelela ukucwiliswa komsindo. Ukuze ufeze lokhu, umthombo ovamile we-audio umsindo ukhonjelwe phansi eziteshini ezimbili, bese uphinde uhlelwe kabusha kumashaneli angu-5.1 uphinde uphinde ulandele izikhulumi ezingu-5 (kanye ne-subwoofer) ngendlela yokudala umsindo ongaqondakali ngaphandle kokulahlekelwa yiziqondiso wezinto zokuqala zomthombo wesiteshi 5.1.
Imiphumela ihlaba umxhwele ngaphezu kweTru-Surround noma iTru-Surround XT.
Okokuqala, umsindo we-panning njengezindiza ezindizayo, izimoto ezisheshayo, noma izitimela, zomsindo ngisho nalapho ziwela esigabeni somsindo; ngokuvamile ku-DD ne-DTS, imisindo ye-panning izo "gcoba" ngokujulile njengoba ihamba isuka kusikhulumi esisodwa kuya kwesinye.
Futhi, imisindo yangaphambili nangaphambili nangemuva yokugeleza igeleza kahle futhi. Okwesibili, imisindo yemvelo, njengokuduma, imvula, umoya, noma amagagasi agcwalisa insimu yomsindo kangcono kunokuba ku-DD noma i-DTS. Isibonelo, esikhundleni sokuzwa imvula ivela ezinhlobonhlobo eziningana, amaphuzu ensimini ezwakalayo phakathi kwalezi ziqondiso zigcwala, ngaleyondlela ukubeka ngaphansi kwesiphepho sezulu, hhayi nje ukulilalela.
I-Circle Surround inikeza ukuthuthukiswa kwe-Dolby Digital kanye nemithombo yomthombo ozwakalayo ozwakalayo ngaphandle kokuhlambalaza injongo yangempela yomxube we-surround surround.
Umjikelezo we-Surround II uthatha lo mqondo ngokuqhubekayo ngokufaka isiteshi esingeziwe sangasese sangemuva, ngaleyo ndlela unikeze ihange lokumemeza okuvela ngqo kumlaleli.
Umshini wekhanda uhambele: I-Dolby Headphone, i-CS Headphone, i-Yamaha Silent Cinema, uSyyth Research , ne- DTS Umakhalekhukhwini: X.
I-Surround Sound ayikhawulelwanga ohlelweni olukhulu lwamashaneli amaningi, kodwa lungasetshenziswa nasekulaleleni i-headphone. Ama-Labs we-SRS, i-Dolby Labs, ne-Yamaha bonke bahlanganise ubuchwepheshe bomsindo oseduze nomvelo wokulalela umakhalekhukhwini.
Ngokuvamile, lapho ulalela umsindo (noma umculo noma ama-movie) umsindo ubonakala uvela ngaphakathi kwekhanda lakho, okungesilo emvelo. I-Dolby Headphone ye-SRS Headphones, i-Yamaha Silent Cinema, no-Smyth Research isebenzisa ubuchwepheshe obungamniki nje umlaleli umsindo ovuzayo kodwa uyisusa ngaphakathi kwekhanda lomlaleli futhi ubeka insimu yomsindo endaweni yangaphambili nangaseceleni ekhanda, okufana nokulalela kwisistimu yomsindo osondelene nesisindo esivamile.
Ngenye intuthuko, i- DTS ithuthukise umakhalekhukhwini we-DTS: X ongakwazi ukunikeza isipiliyoni sokulalela umsindo ojikelezayo wesiteshi esingu-11.1 usebenzisa noma iyiphi i-headphones exhunyiwe kudivayisi yokulalela, njenge-smartphone, isidlali semidiya ephathekayo, noma isamukeli semidlalo yaseshashalazini esihlomele ne-DTS Umsindo: X ukucubungula.
Ukuchazwa Okuphezulu Kuhambelana Nezibuchwepheshe Zomsindo: I- Dolby Digital Plus , i-Dolby TrueHD, ne- DTS-HD Master Audio
Ngokusungulwa kwe-Blu-ray Disc ne-HD-DVD (i-HD-DVD isusiwe), ngokuxhumana noxhumano lwe- HDMI , ukuthuthukiswa kwamafomethi aphezulu aphikisayo we-DTS (kokubili i-DTS-HD) kanye ne-DTS-HD Master Audio) ne-Dolby Digital (ngesimo se-Dolby Digital Plus ne-Dolby TrueHD) inikeza ukunemba okuningiliziwe nokuqinisekisiwe.
Umthamo wesitoreji owandisiwe we-Blu-ray ne-HD-DVD, nokukwazi ukudluliswa kwamandla we-bandwidth we- HDMI , okudingekayo ukuze ufinyelele i-Dolby Digital Plus, i-Dolby TrueHD, ne-DTS-HD, vumele ukukhiqizwa kweqiniso, okuqondayo, okulalelwayo 7.1 Iziteshi zomsindo ozungezile, ngenkathi zibuyela emuva zihambisana nezakhiwo zomsindo omdala wesiteshi 5.1 kanye nezakhi zomsindo / zevidiyo.
Qaphela: i- HD-DVD ishiyiwe kodwa iboniswe kulesi sihloko ngezinhloso zomlando.
I-Dolby Atmos nokuningi
Kusukela ngo-2014, enye ifomethi yomsindo ozungezayo iye yasungulwa kwendawo yaseshashalazini yasekhaya, i-Dolby Atmos. Nakuba ukwakha kwisisekelo esungulwe amafomu aphansi eDolby Surround Sound, i-Dolby Atmos empeleni ikhulula abaxube abaxhumene nabalaleli kusukela ekunciphiseni kwezikhulumi neziteshi ngokugcizelela lapho umsindo udinge khona ukubeka endaweni engaphansi kwe-3-dimensional. Ukuze uthole imininingwane eminingi mayelana nobuchwepheshe be-Dolby Atmos, izinhlelo zokusebenza, nemikhiqizo, bhekisa ezihlokweni ezilandelayo engibhalile:
I-Dolby Atmos - Ingabe Ulungele Umsindo Wama-Channel Surround 64?
I-Dolby Atmos - Kusukela ku-Cinema To Your Home Theater
