Owona mzuzu ungcwele womtshato, ngaphandle kokuphazamiseka kwengxolo

Xa igumbi lonke lithe cwaka, umtshakazi nomyeni bayajongana, belungele ukuthetha amazwi endiwenzayo, nakuphi na ukubethelwa kwekhwelo, okomzuzwana okanye okumfiliba kwesandisi-lizwi kuya kwaphula lo moya undilekileyo nowonwabileyo ngoko nangoko. Ngokwezibalo, ngaphezulu kwe-30% yemitshato iya kudibana namaxesha anzima, kwaye ukusebenza kweaudio yecandelo lesibhambathiso kuqinisekisa ngokuthe ngqo ukuba amava angundoqo omtshato agqibelele.

Inkqubo yesandi somtshato yobuchwephesha ikhusela oku kuzibophelela kubalulekileyo ngetekhnoloji engundoqo kathathu:

Imakrofoni yodidi olungenazingcingo, usebenzisa ukwahluka kokwenyani kwibhendi ye-UHF yonxibelelwano oluzinzileyo lolwimi lothando. Izixhobo zeaudio zobuchwephesha zinokunqanda ngokupheleleyo ukuphazamiseka komqondiso okanye i-awkward frequency crosstalk. Umbhobho womgangatho ophezulu we-microphone uxhotyiswe ngelizwi lomntu eliphuculweyo lokuphendula rhoqo, elinokuthi libambe ngokuchanekileyo ukungcangcazela okufihlakeleyo kunye nokuguquguquka ngokweemvakalelo kwelizwi lomfungi, ngelixa ngokufanelekileyo icinezela ingxolo yokusingqongileyo, iqinisekisa ukuba zonke izithembiso zihanjiswe ngokucacileyo kwaye ngokufudumeleyo kwindlebe yondwendwe ngalunye.

Ukucinezelwa kwengxelo ekrelekrele ukuthintela izikhalo zokugqobhoza. Ngamaxesha ochulumanco ngokweemvakalelo, isithethi sinokusondela kwisithethi singaqondanga. Umcinezeli wengxelo we-DSP owakhelwe kwinkqubo yeaudio yobuchwephesha inokubeka iliso kwaye ijonge ngokuzenzekelayo ukuphindaphindwa kwamanqaku ekhwelo ngexesha lokwenyani, ngokusisiseko ishenxisa izandi ezingathandekiyo nezibukhali zomlozi, ivumela abafikayo kunye nababuki zindwendwe ukuba bahambe ngokukhululekileyo ngaphandle kwamaxhala.

Ukulungiswa kwezwi, ukuphucula ukucaca kwentetho. Iiprosesa ezirekhodiweyo zedijithali ziyakwenza ngobukrelekrele kwaye ziphucule ibhendi yelizwi (ingakumbi i-300Hz-3kHz), ngelixa ngokufanelekileyo ithomalalisa amaza asezantsi atyekele kubudubedube kunye neefrikhwensi eziphezulu ezirhabaxa, zifezekisa ukucaca kolwimi. Oku kuthetha ukuba neendwendwe ezihleli kumqolo ongasemva zinokuva zonke iisilabhili zothando ngokucacileyo.

Isishwankathelo

utyalo-mali kwinkqubo yesandi yomtshato yobuchwephesha ayikona nje ukudlala umculo ongasemva. Ingumgcini wobungcwele bezibhambathiso, isiqinisekiso sokudluliselwa kweemvakalelo, kunye ne-inshorensi ephambili yokuphepha imitshato engafanelekanga. Iqinisekisa ukuba ukuzibophelela kanye ebomini kuthethwa ngokugqibeleleyo kwaye kukhunjulwe, okwenza le nkumbulo yesandi egcinwe zizithethi eziqeqeshiweyo kunye nee-microphone zisacacile kwaye zihamba emva kweminyaka.
