Kuv tau ua haujlwm hauv kev lag luam no yuav luag 30 xyoo lawm. Lub tswv yim ntawm "suab nrov" tej zaum tau nkag mus rau hauv Suav teb thaum cov khoom siv tau muab tso rau hauv kev lag luam hauv xyoo 2000. Vim yog kev tsav tsheb ntawm kev txaus siab rau kev lag luam, nws txoj kev loj hlob sai dua.
Yog li, "Immersive sound" yog dab tsi tiag?
Peb txhua tus paub tias kev hnov lus yog ib qho tseem ceeb tshaj plaws rau tib neeg txoj kev pom. Thaum feem ntau cov neeg poob rau hauv av, lawv pib sau ntau yam suab hauv xwm, thiab tom qab ntawd maj mam tsim ib daim ntawv qhia neural los ntawm kev koom tes ntev ntawm cov txheej txheem pom xws li kev pom, kov, thiab ntxhiab. Raws li lub sijhawm, peb tuaj yeem kos duab qhov peb hnov, thiab txiav txim siab qhov xwm txheej, kev xav, txawm tias kev taw qhia, qhov chaw thiab lwm yam. Hauv ib lub ntsiab lus, qhov pob ntseg hnov thiab hnov hauv lub neej txhua hnub yog qhov tseeb tshaj plaws thiab kev xav ntawm tib neeg.
Lub tshuab electro-acoustic yog ib qho kev txuas ntxiv ntawm kev hnov lus, thiab nws yog "kev rov ua dua" lossis "kev tsim dua" ntawm qee qhov xwm txheej ntawm qib pob ntseg. Peb txoj kev nrhiav kev siv tshuab electro-acoustic muaj cov txheej txheem maj mam. Nrog rau kev nce qib tas mus li ntawm thev naus laus zis, peb cia siab tias muaj ib hnub, lub tshuab electro-acoustic tuaj yeem kho qhov "xwm txheej tiag tiag" uas xav tau. Thaum peb nyob hauv kev tsim dua ntawm lub tshuab electro-acoustic, peb tuaj yeem tau txais qhov tseeb ntawm kev nyob hauv qhov xwm txheej. Kev nkag mus rau hauv, "kev ntxub ntxaug qhov tseeb", qhov kev xav hloov pauv no yog qhov peb hu ua "suab nkag mus rau hauv".
Tau kawg, rau lub suab immersive, peb tseem vam tias yuav tshawb nrhiav ntau ntxiv. Ntxiv rau kev ua rau tib neeg xav tias muaj tseeb dua, tej zaum peb kuj tseem tuaj yeem tsim qee qhov xwm txheej uas peb tsis muaj lub sijhawm lossis qhov tsis zoo los hnov hauv peb lub neej txhua hnub. Piv txwv li, txhua yam suab paj nruag hluav taws xob ncig hauv huab cua, ntsib classical symphony los ntawm txoj haujlwm ntawm tus thawj coj es tsis yog lub auditorium ... Tag nrho cov xwm txheej no uas tsis tuaj yeem hnov hauv lub xeev ib txwm tuaj yeem paub los ntawm "immersive suab", Qhov no yog kev tsim kho tshiab hauv kev kos duab suab. Yog li ntawd, cov txheej txheem kev txhim kho ntawm "immersive suab" yog ib qho txheej txheem maj mam. Hauv kuv lub tswv yim, tsuas yog cov ntaub ntawv suab nrog XYZ peb txoj kab ke tiav tuaj yeem hu ua "immersive suab".
Hais txog lub hom phiaj kawg, lub suab uas nkag mus rau hauv lub ntiaj teb no suav nrog kev tsim cov suab electroacoustic ntawm tag nrho cov suab. Yuav kom ua tiav lub hom phiaj no, tsawg kawg yog ob yam tseem ceeb yuav tsum muaj, ib qho yog kev tsim kho dua tshiab ntawm lub suab thiab qhov chaw suab, kom ob qho tib si tuaj yeem sib xyaw ua ke, thiab tom qab ntawd feem ntau siv HRTF-based (Head Related Transfer Function) binaural suab lossis lub suab hais lus raws li ntau yam algorithms rau kev ua si.
Txhua yam kev tsim kho dua tshiab ntawm lub suab yuav tsum tau muaj kev tsim kho dua tshiab ntawm qhov xwm txheej. Kev tsim kho dua tshiab ntawm cov suab thiab qhov chaw suab raws sijhawm thiab raug tuaj yeem nthuav tawm "qhov chaw tiag tiag", uas siv ntau cov algorithms thiab ntau txoj kev nthuav qhia sib txawv. Tam sim no, qhov laj thawj uas peb "suab immersive" tsis zoo tagnrho yog tias ntawm ib sab tes, cov algorithm tsis meej thiab loj hlob txaus, thiab ntawm qhov tod tes, cov suab thiab qhov chaw suab tau sib txuas thiab tsis sib koom ua ke. Yog li ntawd, yog tias koj xav tsim kom muaj lub kaw lus ua suab immersive tiag tiag, koj yuav tsum coj ob qho tib si los xav txog los ntawm cov algorithms meej thiab loj hlob, thiab koj tsis tuaj yeem ua ib feem xwb.
Txawm li cas los xij, peb yuav tsum nco ntsoov tias thev naus laus zis yeej ib txwm ua haujlwm rau kev kos duab. Qhov zoo nkauj ntawm lub suab suav nrog qhov zoo nkauj ntawm cov ntsiab lus thiab qhov zoo nkauj ntawm lub suab. Cov thawj, xws li cov kab, suab paj nruag, lub suab nrov, lub suab nrov, lub suab nrov, qhov ceev thiab qhov hnyav, thiab lwm yam, yog cov lus qhia tseem ceeb; thaum qhov kawg feem ntau yog hais txog zaus, lub zog, lub suab nrov, qhov chaw zoo nkauj, thiab lwm yam, yog kev qhia tsis meej, pab txhawb kev nthuav qhia ntawm kev kos duab suab, ob qho sib txuas ua ke. Peb yuav tsum paub zoo txog qhov sib txawv ntawm ob qho, thiab peb tsis tuaj yeem muab lub laub tso rau pem hauv ntej ntawm tus nees. Qhov no tseem ceeb heev hauv kev nrhiav lub suab nrov. Tab sis tib lub sijhawm, kev txhim kho thev naus laus zis tuaj yeem muab kev txhawb nqa rau kev txhim kho kev kos duab. Lub suab nrov nrov yog ib qho kev paub dav dav, uas peb tsis tuaj yeem sau luv luv thiab txhais ua ob peb lo lus. Tib lub sijhawm, nws yog ib qho kev tshawb fawb tsim nyog nrhiav. Txhua qhov kev tshawb nrhiav ntawm qhov tsis paub, txhua qhov kev nrhiav ruaj khov thiab tsis tu ncua, yuav tawm ib qho cim ntawm tus dej ntev ntawm electro-acoustics.
