Kubvira pakati pemakore ekuma1990 kunzwika kwakange kwave chinhu chinonyanya kukosha chekugara kwemaimba yeimba, uye, nezvo, yakauya nhoroondo yemafomu akakomberedza kuti azvigadzire kubva.
Vatambi muSroundround Sound Landscape
Vatambi vepamusoro munzvimbo dzakapoteredza nzvimbo ndeyeDolby neDTS, asi kune vamwe / uye vamwe, vakadai seAuro Audio Technologies. Uyewo nepamusoro peimba yose yemitambo yakagadziriswa nemuiti, mune zvekuwedzera iyo inyanzvi yekombiyuta kune imwe kana akawanda emakambani iwayo, uyewo inopa maitiro avo ezvo kuwedzera kushandiswa kwechiitiko chakakomberedza.
Izvo Zvaunoda Kuti Uwane Inopoteredza Inzwi
Kuti uwane ruzha rwenzwi, unoda mutevedzeri wemusha wemitambo yakabatana unotsigira musingani 5.1 muteereri wepisiti system , AV preamp / protoresti yakabatanidzwa ne-multi-channel amplifier uye vatauriri, imba yemitambo-in-a-box system, kana bharinzwi.
Zvisinei, nhamba uye rudzi rwevatauri, kana bhari yezwi, iwe uri mukugadzirisa kwako inongova chikamu chimwechete chekuenzanisa. Kuti uwane rubatsiro rwemhepo yakakomberedza, iwe unodawo kutora zvinyorwa zvehurukuro iyo imba yako yemitambo yakagamuchira, kana imwe yedhidhiyo inobatana, inokwanisa kugadzirisa kana kuita. Izvi zvinogona kuitwa nenzira dzinoverengeka.
Kurwisa Zvakanaka Kududzira
Imwe nzira yekutarisa mhepo yakapoteredza iri kuburikidza nekukodha / kukodhidza nzira. Iyi nzira inoda kuti chiratidzo chepoterera chakakomberedzwe chive chakavhenganiswa, chakakodzwa, uye chakaiswa paDhi kana kuti inokwanisa-faira mafaira ehurukuro, nemupaiti wehuwandu (yakadai semavhidhiyo studio). Chiratidzo chekomba chakakomberedza chinofanira kunge chichiverengwa nemutambo unoenderana-siyana (Ultra HD Blu-ray, Blu-ray, DVD), kana media streamer (Roku Box, Amazon Fire, Chromecast).

Imwe nzira iyo iwe unogona kupinda nayo yakapoteredza inzwi iri kuburikidza nekukomba kwesekukomba. Izvi zvakasiyana, pakuti kunyange zvazvo iwe unoda imba yemitambo, AV processor, kana bharinzwi kuti uwane iyo, haifaniri chero nzira yakakosha yekukodha pamucheto wokutanga.
Panzvimbo pacho, kukomberedza inzwi rinogadziriswa rinoitwa neimba yemitambo (receiver) (etc ...) kuverenga iyo inouya yerineni yerinzwi (iyo inogona kunge yakafananidza kana yedijitori) uye zvino kutsvaga zvinyorwa zvakanyatsopindira izvo zvinopa chiratidzo pane izvo zvinonzwika zvingaiswa kana zvikaitika vakanga vari mumasikirwo akakomberedzwa akakomberedzwa.
Kunyange zvazvo mhinduro yacho isiri yakarurama sepoterera yakapoteredza iyo inoshandisa encoding / decoding system, zvinyorwa hazvina kumbove zvakapoteredza inzwi-encoded.
Chii chikuru pamusoro peiyi pfungwa ndechokuti iwe unogona kutora chero zviratidzo zviviri zvechirwere che stereo uye "upmix" iyo kusvika ku 4, 5, 7, kana kuti mamwe migwagwa, zvichienderana nehupenyu hwehutano hunoshandiswa huchishandiswa.
Kana iwe wakambozvibvunza kuti VHS yako Hifi matepi, Audio Cassettes, CDs, Vinyl Records, uye kunyange FM stereo inotaridzika inoita sezvinopoteredza inzwi, kupoteredza inzwi rinoshandiswa ndiyo nzira yekuzviita.
