Ukuqondakala kweerekhodi zenkundla kufuneka kufikelele kwi-95%, kwaye lonke igama linxulumene nobulungisa benkundla.

Kwinkundla yenkundla ehloniphekileyo nenesidima, ubungqina bonke bunokuba bubungqina obubalulekileyo ekumiseleni ityala. Uphando lubonise ukuba ukuba ukuqondakala kweerekhodi zenkundla kungaphantsi kwe-90%, kunokuchaphazela ukuchaneka kwetyala. Eli lixabiso elibalulekileyo leenkqubo zeaudio zobungcali kwicandelo lobulungisa - azigcini nje ngokudlulisela isandi, kodwa zikwangabagcini bobulungisa benkundla.

Eyona nto iphambili kwinkqubo yesandi yenkundla ikukukhanya kwayo okugqibeleleyo. Isihlalo sejaji, isihlalo sommeli, isihlalo sobungqina, kunye nesihlalo sommangalelwa zonke kufuneka zixhotyiswe ngeemayikrofoni ezinobukrelekrele obuphezulu, ekufuneka zibe namandla okulwa nokuphazamiseka, zibambe ngokuchanekileyo ilizwi lokuqala lesithethi, kwaye zithintele ngokufanelekileyo ingxolo yokusingqongileyo. Okubaluleke ngakumbi, zonke iimayikrofoni kufuneka zisebenzise uyilo olungafunekiyo ukuqinisekisa ukuba ukurekhoda akuyi kuphazanyiswa nokuba isixhobo singasebenzi kakuhle.

Inkqubo yesandisi-lizwi samandla yinxalenye ebalulekileyo ekuqinisekiseni umgangatho wesandi. Isandisi-lizwi esithile senkundla kufuneka sibe nomlinganiselo ophezulu kakhulu wesignali-kwingxolo kunye nokuphazamiseka okuphantsi kakhulu ukuqinisekisa ukuba isignali yesandi ihlala njengoko injalo ngexesha lenkqubo yokukhulisa. Ii-amplifier zedijithali zinokubonelela ngombane ozinzileyo, ziphephe ukuphazamiseka kwesandi okubangelwa kukuguquguquka kwevolthi. Ezi mpawu zenza ukuba zonke iisilabhili kwiirekhodi zenkundla ziphinde zenziwe ngokuchanekileyo.

Iprosesa idlala indima yenjineli yesandi ekrelekrele kwinkqubo yesandi yenkundla. Ingalinganisa ngokuzenzekelayo umahluko wesandi wezithethi ezahlukeneyo, iqinisekisa ukuba ibhesi enkulu yejaji kunye neengxelo ezifihlakeleyo zengqina zinokuboniswa ngesandi esifanelekileyo. Kwangaxeshanye, ikwanayo nomsebenzi wokunciphisa ingxolo ngexesha langempela, onokucoca ingxolo yangasemva efana nesandi somoya opholileyo kunye nesandi sokujika iphepha, kwaye iphucule ubumsulwa bokurekhoda.

Inkqubo yesandi yenkundla esemgangathweni ophezulu ikwafanele iqwalasele ukufana kwentsimi yesandi. Ngokuyila ngononophelo uyilo lwesithethi, kuqinisekiswa ukuba zonke iintetho zinokuviwa ngokucacileyo kuzo zonke iindawo ezikwinkundla. Oku kubaluleke kakhulu kuyilo lwezihlalo zejaji, njengoko kufuneka kuqinisekiswe ukuba yonke ijaji inokufikelela ngokulinganayo kulwazi lwesandi.

Inkqubo yokurekhoda nokugcina idatha yinqanaba lokugqibela lenkqubo yesandi yasenkundleni. Zonke iisignali zesandi kufuneka zifakwe kwidijithali kwaye zigcinwe kunye nesitampu sexesha kunye neempawu zedijithali ukuqinisekisa ukuthembeka kunye nokungaguquguquki kweefayile ezirekhodiweyo. Indlela yokugcina idatha kwiitshaneli ezininzi inokuthintela ukulahleka kwedatha kwaye ibonelele ngesiseko esithembekileyo sophononongo lwesibini okanye olunokwenzeka.
