Umehluko phakathi kwezixube ze-analog nezixube zedijithali

Isihlanganisi somsindo (i-AudioMixingConsole) iyidivayisi esetshenziswa njalo ezinhlelweni zokuqinisa umsindo nokuqoshwa komsindo nevidiyo. Inokufakwa okuningi, futhi amasignali omsindo wesiteshi ngasinye angacutshungulwa ngokuzimela, isibonelo, ingakhuliswa futhi isetshenziselwe i-treble, midrange, ne-bass. Isinxephezelo sekhwalithi yomsindo singangeza ukukhanga kumsindo wokufakwayo, senze ukuma kwendawo komthombo womsindo, njll.; ingakwazi futhi ukuxuba imisindo ehlukahlukene ngesilinganiso sokuxuba okuguquguqukayo; inemiphumela ehlukahlukene (okuhlanganisa ukuphuma kwe-stereo kwesokunxele nakwesokudla, okukhiphayo kokuhlela, ukuphuma kwe-Mono okuxutshwe, ukuqapha okukhiphayo, okukhiphayo okurekhodiwe kanye nemiphumela ehlukahlukene eyisizayo, njll.). Phakathi kwabo, abaxube bangahlukaniswa ngabaxube be-analog nabaxube bedijithali. Iyini imisebenzi yabo eyinhloko kanye nomehluko? Ake sibheke.

Thatha i-digiMIX24, isibonelo semiksi yedijithali yeziteshi ezingama-24 evela e-Yashini emelwe yi-Yihe Technology. Uma iqhathaniswa nezixube ze-analog zendabuko, inezinzuzo ezisobala kakhulu. Ingacushwa ngezindlela ezimbili: iziteshi ezingama-24×8 AUX, noma iziteshi ezingama-24×4 AUX kanye namashaneli angu-24×4 SUB, kanye namaqembu amafader angu-6× DCA. Abasebenzisi bangakhetha ngokuguquguqukayo futhi basabalalise amasignali. Iphuma nesikhulisi semakrofoni esakhiwe nge-ASHLY*. I-digiMIX24 ingasetshenziswa njengesikhungo sokulawula sesistimu kuwo wonke umbukiso. Ngesikhathi esifanayo, imojula ye-Dante ingasetshenziswa ngokuzithandela ukuthumela nokwamukela umsindo wenethiwekhi.

Umsebenzi oyinhloko we-mixer yedijithali ukucubungula amasignali alalelwayo, kodwa into ethile yokucubungula isignali yedijithali ethathwe isampula, i-quantized, futhi ifakwe ikhodi. Lawa masignali ahlanganisa amasignali alalelwayo nokulawula. I-mixer yedijithali idlulisa isibuyekezo Enza uhlelo lokucutshungulwa kwe-algorithm kuhlu olubanzi lwamasiginali. Amasekhethi okulawula namasekhethi okucubungula amasignali we-mixer yedijithali wonke afakwe kwidijithali. Amasignali omsindo wedijithali adluliselwa ngendlela yamafayela (noma imifudlana yedatha) ngokusebenzisa isixhumi esibonakalayo, namafindo, amaswishi, amafader, njll. Inani lokulawula aliseyona isignali yomsindo yangempela ye-analog mixer, kodwa isignali yokulawula. ye-algorithm yedijithali. Ukucutshungulwa kwesiginali ye-digital mixer kuyavumelana nezimo futhi kunembe kakhudlwana, futhi ukugeleza kokucubungula nokubonisa umphumela kucace kakhulu.

Isibonelo, ukuqhathanisa kuphela ipharamitha yobubanzi obuguqukayo, ngokuvamile ububanzi obuguquguqukayo besistimu yomsindo we-analogi bucishe bube ngu-60 dB ngemva kochungechunge lokucubungula, kuyilapho ukubala kwangaphakathi kwenziwa kumxube wedijithali ongu-32-bit, futhi ububanzi obuguquguqukayo bungafinyelela ku-168. ~192dB. Kungashiwo ukuthi umsebenzi we-mixer yedijithali ufana nayo yonke imisebenzi yendawo yokusebenza yomsindo, kufaka phakathi isakhiwo se-hardware kanye nokucubungula isofthiwe. Isakhiwo esiyisisekelo kanye nemisebenzi yemojula ye-mixer yedijithali. I-mixer yedijithali ingase yehluke kakhulu ngokubukeka, kodwa isakhiwo sayo esiyisisekelo siqukethe izingxenye ezilandelayo. Uma ibukwa ngokwehlukana, ibukeka njengesiteshi sokusebenzela esihlanganisa amamojula amaningi okufaka nokukhiphayo asebenzayo.

(1) Isixhumi esibonakalayo se-I/0 silingana nesixhumi esibonakalayo sesignali yokokufaka nokuphumayo kwengxube ye-analog. Izixube eziningi zedijithali zingasebenzisa ne-slot yekhadi yesixhumi esibonakalayo se-analog ukuxhuma amadivaysi esignali ye-analog. Okwamanje, lezi zimbobo zokufaka ze-analogi zisetshenziselwa ukusekela Isiteshi sishintshele kudijithali ngokugcwele, futhi izinhlobo zokusebenzelana kwedijithali zifaka i-AES/EBU, S/PDIF namanye amazinga.

(2) Ingxenye yokucubungula isignali (i-DSP) iwumgogodla we-mixer yedijithali futhi inesibopho sokucutshungulwa okuhlukahlukene nokucubungula amasignali edijithali. Inquma ngokuyisisekelo umsebenzi kanye nekhwalithi yawo wonke umxube. (3) Ingxenye elawulayo ye-mix, okuyi-interface yengxoxo yekhompyutha yomuntu, ibukeka ifana nendikimba eyinhloko ye-analog mixer. Kodwa-ke, izingxenye zingamafader okulawula kuphela, amafindo, izinkomba, njll., futhi azidluliswanga. Ngezimpawu zomsindo, ezinye izihlanganisi zingaxhunywa kumamonitha wevidiyo, amakhibhodi, namagundane. Ukulawula isofthiwe yomsebenzisi nokulawula izingxenyekazi zekhompuyutha kunomphumela ofanayo.

(4) Umsingathi we-mixer (ingxenye yokulawula ikhompuyutha ye-CPU), ehlanganiswe nokusebenza kwesofthiwe, ibona ukukhishwa komyalo, ukulawulwa kokugeleza kwesignali kanye neminye imisebenzi yayo yonke i-mixer. (5) Ingxenye yokuphakelwa kwamandla ifana ne-analog mixer, ngokuvamile isebenzisa imojuli yamandla yangaphandle ehlukile.

Njengomkhiqizo wesizukulwane sokuqala, izixube ze-analog empeleni ziphansi kakhulu ekusebenzeni. Umsebenzi oyinhloko we-analog mixer ukucubungula amasignali alalelwayo. Into amasiginali kagesi we-analog eqhubekayo. Ngaphezu kokuqedela ukukhulisa okuvamile, ukusatshalaliswa, ukuxutshwa, kanye nokucubungula kokudlulisa, futhi inemisebenzi esemqoka elandelayo: 1. Ukumatanisa kwezinga nokuvinjwa ;2. Ukukhulisa isignali nokulinganisa imvamisa; 3. Ukucubungula okunamandla; 4. Ukusatshalaliswa kwamasignali nokuxuba; 5. Ukudala imiphumela ekhethekile njengoba kudingeka, ngezinye izikhathi ngokucutshungulwa okukhethekile kusetshenziswa izinto ezisetshenziswayo eziwusizo.
