Ndakhala mumakampaniwa kwa zaka pafupifupi 30. Lingaliro la "mawu ozama" mwina linafika ku China pamene zidazi zinayamba kugwiritsidwa ntchito m'mabizinesi mu 2000. Chifukwa cha kukonda malonda, chitukuko chake chimakhala chofunikira kwambiri.
Ndiye, kodi "Immersive sound" kwenikweni ndi chiyani?
Tonsefe tikudziwa kuti kumva ndi njira imodzi yofunika kwambiri yodziwira anthu. Anthu ambiri akagwa pansi, amayamba kusonkhanitsa mawu osiyanasiyana m'chilengedwe, kenako pang'onopang'ono amapanga mapu a mitsempha kudzera mu mgwirizano wa nthawi yayitali wa njira zodziwira monga kuwona, kukhudza, ndi kununkhiza. Pakapita nthawi, timatha kujambula zomwe timamva, ndikuweruza zomwe zikuchitika, momwe zimakhalira, ngakhale momwe zimakhalira, malo ndi zina zotero. Mwanjira ina, zomwe khutu limamva ndi kumva m'moyo watsiku ndi tsiku ndi zomwe anthu amazindikira komanso zenizeni komanso zachibadwa.
Dongosolo la electro-acoustic ndi njira yowonjezerera kumva, ndipo ndi "kuberekanso" kapena "kukonzanso" kwa malo enaake pamlingo womvera. Kufunafuna kwathu ukadaulo wa electro-acoustic kumakhala ndi njira yocheperako. Ndi kupita patsogolo kosalekeza kwa ukadaulo, tikuyembekeza kuti tsiku lina, dongosolo la electro-acoustic likhoza kubwezeretsa molondola "malo enieni" omwe tikufuna. Tikadzakhala mukuberekanso dongosolo la electro-acoustic, titha kupeza zenizeni za kukhala pamalopo. Kumiza, "konyansa kwenikweni", lingaliro ili la kusintha ndilo lomwe timatcha "mawu omiza".
Zachidziwikire, kuti tipeze mawu ozama, tikuyembekezerabe kufufuza zambiri. Kuwonjezera pa kupangitsa anthu kumva ngati enieni, mwina tingathenso kupanga zochitika zina zomwe sitili ndi mwayi kapena zachilendo zoti tizimva m'moyo wathu watsiku ndi tsiku. Mwachitsanzo, mitundu yonse ya nyimbo zamagetsi zikuzungulira mlengalenga, zikumvera nyimbo zakale kuchokera pamalo a woyendetsa m'malo mwa holo... Zochitika zonsezi zomwe sizingamveke bwino zitha kuchitika kudzera mu "mawu ozama", Ichi ndi chatsopano mu zaluso zamawu. Chifukwa chake, njira yopangira "mawu ozama" ndi njira yopita pang'onopang'ono. M'malingaliro mwanga, chidziwitso cha mawu chokha chokhala ndi ma axes atatu a XYZ ndi chomwe chingatchedwe "mawu ozama".
Ponena za cholinga chachikulu, mawu ozama amaphatikizapo kubwerezabwereza kwa mawu onse pogwiritsa ntchito electroacoustic. Kuti mukwaniritse cholinga ichi, pakufunika zinthu ziwiri, chimodzi ndi kukonzanso kwamagetsi kwa chinthu cha mawu ndi malo a mawu, kuti ziwirizi ziphatikizidwe mwachilengedwe, kenako nkugwiritsa ntchito HRTF-based (Head Related Transfer Function) binaural sound kapena speaker sound field kutengera ma algorithms osiyanasiyana osewerera.
Kukonzanso kulikonse kwa mawu kumafuna kukonzanso mkhalidwe. Kubwerezabwereza kwa zinthu za mawu ndi malo omveka bwino panthawi yake kungapereke "malo enieni" owoneka bwino, momwe ma algorithm ambiri ndi njira zosiyanasiyana zowonetsera zimagwiritsidwa ntchito. Pakadali pano, chifukwa chomwe "mawu athu ozama" sali abwino kwambiri ndikuti mbali imodzi, algorithm si yolondola komanso yokhwima mokwanira, ndipo mbali inayo, chinthu cha mawu ndi malo omveka sizigwirizana kwambiri ndipo sizimalumikizidwa bwino. Chifukwa chake, ngati mukufuna kupanga makina ogwiritsira ntchito mawu omveka bwino, muyenera kuganizira mbali zonse ziwiri kudzera mu ma algorithm olondola komanso okhwima, ndipo simungathe kungochita gawo limodzi.
Komabe, tiyenera kukumbukira kuti ukadaulo nthawi zonse umathandiza zaluso. Kukongola kwa mawu kumaphatikizapo kukongola kwa zomwe zili mkati ndi kukongola kwa mawu. Zoyamba, monga mizere, nyimbo, kamvekedwe ka mawu, kamvekedwe ka mawu, liwiro ndi kuuma kwake, ndi zina zotero, ndi mawu ofunikira; pomwe zomalizazi zimatanthauza kuchuluka kwa mawu, mphamvu, kukweza mawu, kupanga malo, ndi zina zotero, ndi mawu omveka bwino, omwe amathandiza kuwonetsa zaluso zomveka, ziwirizi zimagwirizana. Tiyenera kudziwa bwino kusiyana pakati pa ziwirizi, ndipo sitingathe kuyika ngolo patsogolo pa kavalo. Izi ndizofunikira kwambiri pakufunafuna mawu ozama. Koma nthawi yomweyo, chitukuko cha ukadaulo chingapereke chithandizo pakukula kwa zaluso. Mawu ozama ndi gawo lalikulu la chidziwitso, lomwe sitingathe kulifotokoza mwachidule ndi kulifotokoza m'mawu ochepa. Nthawi yomweyo, ndi sayansi yoyenera kutsatiridwa. Kufufuza konse kwa zosadziwika, zinthu zonse zokhazikika komanso zopitilira, kudzasiya chizindikiro pamtsinje wautali wamagetsi.
