Nabaye mu nganda imyaka igera kuri 30.Igitekerezo cy '"ijwi ryimbitse" birashoboka ko ryinjiye mu Bushinwa igihe ibikoresho byakoreshwaga mu bucuruzi mu 2000. Kubera inyungu z’ubucuruzi, iterambere ryacyo ryihutirwa.
None, "Ijwi ryimbere" ni iki?
Twese tuzi ko kumva ari bumwe muburyo bwingenzi bwo kwiyumvisha abantu.Iyo abantu benshi baguye hasi, batangira gukusanya amajwi atandukanye muri kamere, hanyuma buhoro buhoro bakora ikarita yumutima binyuze mubufatanye bwigihe kirekire bwuburyo bwimyumvire nko kureba, gukoraho, no kunuka.Igihe kirenze, dushobora gushushanya ibyo twumva, tugacira urubanza imiterere, amarangamutima, ndetse nicyerekezo, umwanya nibindi.Mu buryo bumwe, ibyo ugutwi kwumva no kumva mubuzima bwa buri munsi ni imyumvire nyayo kandi yimitekerereze yabantu.
Sisitemu ya electro-acoustic niyaguka rya tekinike yo kumva, kandi ni "imyororokere" cyangwa "kongera kurema" ibintu runaka kurwego rwo kumva.Gukurikirana tekinoroji ya electro-acoustic ifite inzira gahoro gahoro.Hamwe niterambere ryiterambere ryikoranabuhanga, turizera ko umunsi umwe, sisitemu ya electro-acoustic ishobora kugarura neza "ibintu nyabyo" byifuzwa.Iyo turi mubyororokere bya sisitemu ya electro-acoustic, dushobora kubona realism yo kuba mubyabaye.Immersive, "iteye ishozi nyayo", iyi myumvire yo gusimburwa nicyo twita "ijwi ryimbitse".
Birumvikana, kumajwi yibintu, turacyizera gushakisha byinshi.Usibye gutuma abantu bumva ko ari ukuri, birashoboka ko dushobora no gukora ibintu bimwe na bimwe tudafite amahirwe cyangwa ibintu bidasanzwe byo kumva mubuzima bwacu bwa buri munsi.Kurugero, ubwoko bwose bwumuziki wa elegitoronike uzenguruka mu kirere, uhura na simfoni ya kera uhereye kumwanya wuyobora aho kuba muri auditorium ... Aya mashusho yose adashobora kumvikana muburyo busanzwe arashobora kugerwaho binyuze mumajwi "immersive", Ibi ni agashya mubuhanzi bwamajwi.Kubwibyo, inzira yiterambere ry "ijwi ryimbitse" ni inzira gahoro gahoro.Njye mbona, amakuru yumvikana gusa afite XYZ yuzuye amashoka atatu ashobora kwitwa "ijwi ryimbitse".
Kubireba intego nyamukuru, amajwi yibintu arimo amashanyarazi ya electroacoustic yerekana amajwi yose.Kugirango ugere kuriyi ntego, byibuze harakenewe ibintu bibiri, kimwe nukwiyubaka muburyo bwa elegitoronike yijwi ryumwanya hamwe nijwi ryamajwi, kugirango byombi bishobore guhuzwa, hanyuma bigakorwa cyane cyane HRTF ishingiye (Head Related Transfer Function) amajwi ya binaural cyangwa umuvugizi wamajwi ashingiye kuri algorithms zitandukanye zo gukina.
Kwiyubaka kwamajwi byose bisaba kongera kwiyubaka.Kwororoka ku gihe kandi neza kwijwi ryibintu hamwe nijwi ryamajwi birashobora kwerekana "umwanya nyawo", aho algorithm nyinshi nuburyo butandukanye bwo kwerekana.Kugeza ubu, impamvu ituma "ijwi ryacu ryinjira" ritaba ryiza cyane nuko kuruhande rumwe, algorithm idasobanutse neza kandi ikuze bihagije, kurundi ruhande, ikintu cyijwi hamwe nijwi ryamajwi biracikamo ibice kandi ntibikomeye. byahujwe.Kubwibyo, niba ushaka kubaka sisitemu yo gutunganya acoustique rwose, ugomba kuzirikana ibintu byombi ukoresheje algorithms zuzuye kandi zikuze, kandi ntushobora gukora igice kimwe gusa.
Ariko, tugomba kwibuka ko ikoranabuhanga rihora rikora ubuhanzi.Ubwiza bwijwi burimo ubwiza bwibirimo nubwiza bwijwi.Ibya mbere, nk'imirongo, injyana, amajwi, injyana, ijwi ry'ijwi, umuvuduko n'uburemere, n'ibindi, ni imvugo yiganje;mugihe ibyanyuma bivuga cyane cyane kuri frequence, dinamike, ijwi rirenga, gushushanya umwanya, nibindi, ni imvugo idasobanutse, ifasha kwerekana ibihangano byamajwi, byombi byuzuzanya.Tugomba kumenya neza itandukaniro ryombi, kandi ntidushobora gushyira igare imbere yifarasi.Ibi nibyingenzi cyane mugukurikirana amajwi yibintu.Ariko icyarimwe, iterambere ryikoranabuhanga rirashobora gutanga inkunga yo guteza imbere ubuhanzi.Ijwi ryibiza ni igice kinini cyubumenyi, tudashobora kuvuga muri make no gusobanura mumagambo make.Igihe kimwe, ni siyanse ikwiye gukurikirana.Ubushakashatsi bwose butazwi, ibintu byose bihamye kandi bihoraho, bizasiga ikimenyetso kumugezi muremure wa electro-acoustics
