Incazelo ye-VBR
Kuyini i-VBR Encoding?
I- B ithelekayo i- R iyadla indlela yokwenza ikhodi eyenzelwe ukufeza ikhwalithi yezwi elihle ngokulinganisa usayizi wefayela kunekhodi ye- CBR (Constant Bit Rate). Lokhu kufinyelelwa ngokushintsha ngokuqhubekayo isilinganiso esincane ngesikhathi senqubo yokufaka ikhodi kuye ngokuthi uhlobo lwomsindo. Isibonelo, uma kukhona ukuthula okuzofakwa ikhodi bese izinga lokunciphisa liyancipha ukuze kulungiswe usayizi wefayela. Ngokuphambene, uma umsindo ozodlalwa uqukethe ukuxuba okuyinkimbinkimbi yama frequ bese inani elincane likhuphuka ukuze linikeze ikhwalithi elizwakalayo elizwakalayo.
Ukusebenzisa indlela yekhodi ye-VBR kuzokhiqiza ifayela elilalelwayo elizoba namazinga aguquguqukayo kusuka ku-128Kbps kuya ku-320Kbps kuye ngokuthi ubunzima bama frequency omsindo.
