Zimene Mumakonda
Kumveka phokoso ndi mawu ogwiritsidwa ntchito ku mitundu yosiyanasiyana ya maofesi omwe amathandiza omvetsera kuti amve phokoso lochokera kumalo osiyanasiyana, malingana ndi magwero.
Kuyambira pakati pa zaka za m'ma 1990 kuzungulira kuzungulira kwakhala mbali yofunikira pachitetezo cha nyumba, ndipo, ndi icho, chafika mbiriyakale ya mawonekedwe oyandikana nawo.
Osewera mu malo ozungulira Surround Sound
Osewera pamasewera ozungulira ndi Dolby ndi DTS, koma pakhala pali / ena, monga Auro Audio Technologies. Komanso pafupi ndi makina opanga mafilimu omwe ali ndi nyumba, kuphatikizapo matekinoloje a kampani imodzi kapena angapo, amaperekanso zophatikizira zawo kuti apititse patsogolo zochitikazo.
Zimene Mukufunikira Kufikira Pansi Phokoso
Kuti mukumva phokoso lamveka, mukufunikira kothandizira kanyumba kamene kamagwirizana ndi maulendo osachepera asanu omwe amagwiritsa ntchito makanema , AV preamp / purosesa yomwe imayendetsedwa ndi magetsi amphamvu ndi oyankhula, maofesi apanyumba, kapena bar.
Komabe, chiwerengero ndi mtundu wa okamba, kapena bar ya voliyumu, yomwe muli nayo mumasewero anu ndi gawo limodzi la equation. Kuti mupeze phindu la phokoso lozungulira, muyeneranso kupeza mauthenga omwe audio yanu yamulankhulidwe, kapena chipangizo china chogwirizana, amatha kusankha. Izi zikhoza kuchitika m'njira zingapo.
Yendetsani Kudodometsa Kumveka
Njira imodzi yofikira phokoso loyang'ana ponseponse ndi kudzera mu ndondomeko ya encoding / decoding. Njirayi imafuna kuti chizindikiro chozungulira chozungulira chikhale chosakanikirana, chosindikizidwa, ndikuyika pa fayilo kapena mauthenga a voliyumu, pogwiritsa ntchito wothandizira (monga studio). Chizindikiro chozungulira chozungulira chiyenera kuwerengedwa ndi chipangizo chowonekera chogwirizana (Ultra HD Blu-ray, Blu-ray, DVD), kapena media streamer (Roku Box, Amazon Fire, Chromecast).
Wosewera kapena streamser amatumiza chizindikiro ichi chojambulidwa kudzera ku kulumikiza kwa digito / coaxial kapena HDMI kuwunikira nyumba, AV preamp processor, kapena chipangizo china chogwirizana chomwe chingathe kudziwa chizindikiro, ndikugawira njira zoyenera ndi oyankhula kuti athe kumvedwa ndi omvera.
Zitsanzo za mawonekedwe ozungulira omwe akugwera m'gulu ili ndi awa: Dolby Digital, EX, Dolby Digital Plus , Dolby TrueHD , Dolby Atmos , DTS Digital Surround , DTS 92/24 , DTS-ES , DTS-HD Master Audio , DTS: X , ndi Auro 3D Audio .
Yendetsani Zojambula
Njira ina imene mungathe kuyendera kuzungulira ponseponse ndikumvetsera kuzungulira. Izi ndi zosiyana, pakuti ngakhale kuti mukusowa malo oyendetsera kunyumba, pulogalamu ya AV, kapena phokoso loti lilowetse, silikufuna njira yododometsa yapadera.
M'malo mwake, kuzungulira phokoso kumapangidwe ndi wolandila kunyumba (etc) kuwerenga chizindikiro chomwe chikubwera (chomwe chingakhale analog kapena digito) ndikuyang'ana zizindikiro zomwe zakhala zikugwiritsidwa ntchito zomwe zimapereka chisonyezo pamene zikumveka zikhoza kuikidwa ngati anali mu maonekedwe ozungulira omvera.
Ngakhale zotsatira siziri zolondola monga kuzungulira pozungulira zomwe zimagwiritsa ntchito encoding / decoding system, zomwe zilipo sizinayambe kuzungulira pododometsa.
Chomwe chiri chabwino pa mfundoyi ndi chakuti mukhoza kutenga chizindikiro chilichonse cha stereo ndi "kusakaniza" kwazitsulo 4, 5, 7, kapena zina, malingana ndi mawonekedwe omwe akuyendetsedwa bwino.
Ngati munayamba mwadzifunsa kuti VHS Hifi yanu matepi, Audio Cassettes, CDs, Vinyl Records, komanso ngakhale ma FM stereo amawoneka ngati phokoso lozungulira, kuzungulira phokoso ndi njira yochitira.
Zina zomwe zimapanga mafilimu opangira mafilimu omwe amaikidwa pamakina ambiri a kunyumba, ndi zipangizo zina zowonjezera, zimaphatikizapo Dolby Pro-Logic (mpaka 4), Pro-Logic II (mpaka 5), IIx kumasewu asanu ndi awiri kapena asanu ndi awiri (7) omwe amalembedwa ndi ma channel mpaka 7.1), ndi Dolby Surround Upmixer (yomwe ingasokonezeke kuchokera pa 2, 5, kapena 7 njira zopita ku Dolby Amosi ngatizomwe zili pafupi ndi njira ziwiri kapena zingapo).
Pa DTS mbali, pali DTS Neo: 6 (ikhoza kusakaniza magawo awiri kapena asanu kumasewu 6), DTS Neo: X (akhoza kusakaniza 2, 5, kapena 7 njira zopita 11.1), ndi DTS Neural: X (yomwe imagwira ntchito mofananamo monga Dolby Atmos upmixer).
Njira zina zowonjezera mauthenga monga Audyssey DSX (zingathe kukweza chizindikiro chowonetsera chithunzi cha 5.1 powonjezeramo njira imodzi yowonjezera kapena chingwe chakumbuyo kapena onse awiri.
Komanso, Auro 3D Technologies imapangitsanso mafilimu omwe amawoneka mofanana ndi Dolby Surround ndi DTS Neural: X.
Ngakhale THX imapereka njira zowonongeka zozungulira zomwe zakonzedwa kuti zikhale bwino pachitetezo chakumvetsera kumvetsera kwa mafilimu, masewera, ndi nyimbo.
Monga momwe mukuwonera pali zambiri zazomwe zikumveka bwino komanso zosankha zomwe zikupezeka, malingana ndi chizindikiro / chowonetseratu cha mpikisano wanu wa zisudzo, AV processor, kapena bar, koma si zonse.
Kuwonjezera pa zojambula zomveka kuzungulira ndi kupanga mawonekedwe pamwambapa, opanga mafilimu a kunyumba, opanga ma AV, ndi ojambula nyimbo amadzipangira zokoma zawo monga Anthem Logic (Anthem AV) ndi Cinema DSP (Yamaha).
Zomwe Zikuzungulira
Zomwe zili pamwambazi zikulingalira bwino komanso zojambula bwino zimagwira ntchito zowonongeka, zosiyana ndi zomwe zimagwiritsidwa ntchito ndi Mabaibulo Owonetsera - apa ndi kumene kumveka phokoso lozungulira. malo owonetsera masewera a nyumba monga njira ina) yomwe imapereka "kuzungulira" kumvetsera ndi oyankhula awiri okha (kapena oyankhula awiri ndi subwoofer).
Sewero Surround (Sony), AirSurround Xtreme (Yamaha) Ndimodziwika ndi maina angapo (malingana ndi chizindikiro cha barreje) Phase Cue (Zvox), Circle Surround (SRS / DTS - Circle Surround ingagwire ntchito limodzi ndi magwero awiri osasindikizidwa ndi osungidwa), S-Force Front Surround (Sony), AirSurround Xtreme (Yamaha ), ndi Dolby Virtual Speaker (Dolby), malo ozungulirana kwenikweni sakhala owona bwino ponseponse, koma gulu la matelojeti omwe, pogwiritsa ntchito kusintha-kayendedwe, kuchedwa kwa mawu, kulingalira kwabwino, ndi njira zina, zimakumbukira makutu anu akukumana ndi kuzungulira kuzungulira.
Malo ozungulira angagwire ntchito imodzi mwa njira ziwiri, zingathe kutenga mayendedwe awiri ndi kupereka chithandizo chozungulira, kapena chingatenge chizindikiro chachitsulo chachisanu ndi chimodzi, chiyiyanjanitse mpaka pazitsulo ziwiri, ndiyeno gwiritsani ntchito zizindikirozo kuti apereke zochitika zomveka pozungulira pokhapokha oyankhula omwe alipo omwe akuyenera kugwira nawo ntchito.
Chinthu china chodabwitsa pa Virtual Surround phokoso ndi chomwe chingagwiritsidwe ntchito popereka chidziwitso chomveka chozungulira kumalo omvetsera kumvetsera. Zitsanzo ziwiri ndi Yamaha Silent Cinema, ndi Dolby Headphone.
Kupititsa patsogolo Ambience
Kumveka phokoso kungakhale kumaliza kupyolera mwa kukhazikitsidwa kwa Kupititsa patsogolo kwa Ambience. Pamalo olandirako ambiri panyumba, makonzedwe othandizira amvekedwe owonjezeka omwe amatha kuwonjezera chiwonetsero kuti amvetsere kumvetsera, kaya zokhudzana ndi magwero amadziwika kapena zasinthidwa.
Kupititsa patsogolo chidziwitso kumayambira kumagwiritsidwe ntchito ka Reverb kuti iwonetse malo akumvetsera akuluakulu kumbuyo kwa zaka za m'ma 60 ndi 70 (amagwiritsidwa ntchito kwambiri mu vodiyo), koma moona, monga momwe amagwiritsidwira ntchito panthawiyo, zingakhale zokhumudwitsa kwambiri.
Komabe, njira zomwe ziganizidwezi zimagwiritsidwa ntchito masiku ano, ndi njira zomvetsera kapena zomvera zomwe zimaperekedwa pa omvera ambiri a kunyumba ndi AV processors. Njirazo zimaphatikizapo zowonjezera zamtunduwu zomwe zimayenera kugwiritsidwa ntchito pazinthu zamtunduwu kapena zimayesa malo ndi malo omwe amamangidwe.
Mwachitsanzo, pangakhale njira zomvetsera zomwe zimaperekedwa ku Movie, Music, Game, kapena Masewera a Zamasewera - ndipo nthawi zina zimakhala zowonjezereka (Sci-Fi movie, Adventure Movie, Jazz, Rock, etc ...).
Komabe, palinso zambiri. Ena olandira masewero apanyumba akuphatikizanso zinthu zomwe zimagwiritsa ntchito maofesi a chipinda, monga Movie Theatre, Auditorium, Arena, kapena Church.
Kukhudza kotsiriza kumene kulipo kumalo otsekemera apamwamba a kunyumba, ndi luso la ogwiritsa ntchito kuti apitirize kukonza njira yoyenera kumvetsera / zochitika zamanja kuti apereke zotsatira zabwino mwa kusintha zinthu monga kukula kwa chipinda, kuchedwa, kukhudzika, ndi nthawi yobwereza.
Mfundo Yofunika Kwambiri
Monga momwe mukuonera, Surround Sound sizongowonjezera chabe. Malinga ndi zomwe zilipo, kusewera chipangizo, ndi zida zam'chipinda, pali njira zambiri zomvetsera zomwe zingathe kupezeka ndikugwirizana ndi zosowa zanu.
