Ngcaciso yeVBR
Yintoni i-VBR Encoding?
I- B i- R iyadla isitya sekhowudi ekwenzelwe ukuphumeza umgangatho ophezulu omsindo kunye nokulinganisa ubungakanani befayile kuneCBR (i-Constant Bit Rate encoding). Oku kufezekiswa ngokuqhubekayo ngokutshintsha umlinganiselo omncinci ngexesha lwenkqubo yokukhokha ngokuxhomekeka kwimeko yesandi. Ngokomzekelo, ukuba kukho ukuthula okumele kubhalwe ngekhowudi ke umlinganiselo wancinci uyancitshiswa ukuze ukwandise ubungakanani befayili. Ngokwahlukileyo, ukuba i-audio emele idlalwe iqukethe umxube odibeneyo wee-frequencies ke uhla lwamanani lwandisiwe ukunika umgangatho ophezulu omsindo.
Ukusebenzisa indlela ye-encoding ye-VBR iza kuvelisa iifayile ezivakalayo eziza kuba namaxabiso aguquguqukayo ukusuka kwi-128Kbps ukuya kwi-320Kbps ngokuxhomekeka kobunzima bee-frequencies.
