Kuv tau nyob hauv kev lag luam rau ze li 30 xyoo. Lub tswv yim ntawm "immersive sound" tej zaum nkag mus rau Tuam Tshoj thaum cov khoom siv tau muab tso rau hauv kev lag luam hauv xyoo 2000. Vim tias kev tsav tsheb ntawm kev lag luam nyiam, nws txoj kev loj hlob sai sai.
Yog li, dab tsi yog "Immersive sound"?
Peb txhua tus paub tias kev hnov lus yog ib qho tseem ceeb tshaj plaws ntawm kev nkag siab rau tib neeg. Thaum cov neeg feem coob poob rau hauv av, lawv pib sau ntau lub suab hauv qhov xwm txheej, thiab tom qab ntawd maj mam tsim daim ntawv qhia neural los ntawm kev sib koom tes ntev ntawm txoj kev xaav xws li kev pom, kov, thiab hnov tsw. Nyob rau tib lub sijhawm, peb tuaj yeem qhia qhov peb hnov, thiab txiav txim rau lub ntsiab lus, kev xav, txawm tias kev taw qhia, qhov chaw thiab lwm yam. Hauv kev nkag siab, qhov uas pob ntseg hnov thiab hnov hauv lub neej niaj hnub yog qhov kev xav tiag tiag thiab kev xav ntawm tib neeg.
Lub tshuab hluav taws xob-acoustic yog qhov kev txuas ntxiv ntawm kev hnov lus, thiab nws yog "kev tsim tawm" lossis "rov tsim dua tshiab" ntawm qee qhov xwm txheej ntawm lub suab. Peb nrhiav kev siv tshuab electro-acoustic muaj cov txheej txheem maj mam. Nrog rau kev nce qib ntawm kev siv thev naus laus zis, peb cia siab tias muaj ib hnub, lub tshuab hluav taws xob-acoustic tuaj yeem kho qhov xav tau "qhov tseeb". Thaum peb nyob rau hauv kev tsim tawm ntawm lub tshuab hluav taws xob-acoustic, peb tuaj yeem tau txais qhov tseeb ntawm qhov tshwm sim. Immersive, "dhuav qhov tseeb", qhov kev nkag siab ntawm kev hloov pauv yog qhov peb hu ua "immersive sound".
Tau kawg, rau lub suab nrov, peb tseem cia siab tias yuav tshawb nrhiav ntxiv. Ntxiv rau qhov ua rau tib neeg xav tias muaj tseeb tiag, tej zaum peb kuj tuaj yeem tsim qee qhov xwm txheej uas peb tsis muaj lub sijhawm lossis qhov txawv txav los xav hauv peb lub neej niaj hnub. Piv txwv li, txhua yam ntawm cov suab paj nruag hluav taws xob ncig hauv huab cua, muaj kev sib tw classical los ntawm txoj hauj lwm ntawm tus neeg xyuas pib es tsis yog lub auditorium ... Tag nrho cov xwm txheej no uas tsis tuaj yeem hnov hauv lub xeev ib txwm muaj peev xwm paub tau los ntawm "lub suab nrov", Qhov no yog kev tsim kho tshiab hauv suab paj nruag. Yog li ntawd, cov txheej txheem kev loj hlob ntawm "lub suab nrov" yog ib txoj kev gradual. Hauv kuv lub tswv yim, tsuas yog cov ntaub ntawv suab nrog ua tiav XYZ peb axes tuaj yeem hu ua "suab nrov".
Nyob rau hauv cov nqe lus ntawm lub hom phiaj kawg, immersive suab muaj xws li cov electroacoustic reproduction ntawm tag nrho cov suab scene. Txhawm rau ua tiav lub hom phiaj no, tsawg kawg yog ob yam yuav tsum tau ua, ib qho yog kev tsim kho hluav taws xob ntawm lub suab thiab qhov chaw suab, kom ob qho tib si tuaj yeem ua ke, thiab tom qab ntawd feem ntau siv HRTF-raws li (Lub Taub Hau Txuas Txuas Kev Ua Haujlwm) binaural suab lossis hais lus suab teb raws li ntau yam algorithms rau playback.
Ib qho kev tsim kho ntawm lub suab yuav tsum muaj kev tsim kho dua tshiab. Kev tsim tawm raws sij hawm thiab raug ntawm cov ntsiab lus suab thiab qhov chaw suab tuaj yeem nthuav tawm qhov "qhov chaw tiag tiag", uas siv ntau cov algorithms thiab ntau txoj kev nthuav qhia. Tam sim no, yog vim li cas vim li cas peb "lub suab nrov" tsis yog qhov zoo tshaj plaws yog tias ntawm ib sab, lub algorithm tsis meej thiab paub tab txaus, thiab ntawm qhov tod tes, lub suab lub suab thiab lub suab nrov yog qhov sib txuas thiab tsis nruj heev. Yog li ntawd, yog tias koj xav tsim kom muaj ib qho kev ua tiav acoustic tiag tiag, koj yuav tsum coj ob qho tib si rau hauv kev txiav txim siab los ntawm qhov tseeb thiab paub tab algorithms, thiab koj tsis tuaj yeem ua ib feem xwb.
Txawm li cas los xij, peb yuav tsum nco ntsoov tias technology yeej ib txwm ua haujlwm rau kev kos duab. Kev zoo nkauj ntawm lub suab suav nrog kev zoo nkauj ntawm cov ntsiab lus thiab kev zoo nkauj ntawm lub suab. Cov qub, xws li kab, suab paj nruag, tonality, atherosclerosis, suab nrov, ceev thiab hnyav, thiab lwm yam, yog cov ntsiab lus tseem ceeb; hos lub tom kawg mas yog hais txog zaus, dynamics, nrov, qhov chaw shaping, thiab lwm yam, yog Implicit qhia, pab kev nthuav qhia ntawm suab kos duab, ob qho tib si ntxiv ib leeg. Peb yuav tsum paub zoo txog qhov sib txawv ntawm ob, thiab peb tsis tuaj yeem tso lub laub ua ntej tus nees. Qhov no yog qhov tseem ceeb heev hauv kev nrhiav lub suab nrov. Tab sis nyob rau tib lub sijhawm, kev txhim kho thev naus laus zis tuaj yeem muab kev txhawb nqa rau kev tsim cov duab kos duab. Lub suab nrov yog qhov kev paub dav dav, uas peb tsis tuaj yeem sau thiab txhais ua ob peb lo lus. Nyob rau tib lub sij hawm, nws yog ib tug science tsim nyog mus nrhiav. Tag nrho cov kev tshawb fawb ntawm cov tsis paub, tag nrho cov steadfast thiab persistent caum, yuav tawm ib lub cim rau ntawm tus dej ntev ntawm electro-acoustics.
