Uma ufuna ukuchofoza ama CD wakho omculo kufomethi yomsindo njenge- MP3 , i- WMA , i- AAC , njll, noma udinga ukuguqula phakathi kwamafomethi, khona-ke umqondo omuhle ukwazi ukuthi i- CBR ne-VBR isho ukuthini ngaphambi kokuba uqale.
Ngezansi isisekelo sokuthi lezi zifinyezo zisho ukuthini, zisebenza kanjani, futhi umehluko phakathi kwezinqubo ezimbili zokufaka ikhodi.
Qaphela: I- CBR ne-VBR nayo izifinyezo zezinye izinhlobo ezihlobene ne-tech njengefayela le-CDisplay Archived Comic Book nerekhodi ye-boot volume , kodwa akukho lutho olwenziwe ngokufaka ikhodi njengoba kuchaziwe lapha.
Ukubhala nge-CBR
I-CBR imelela i- bitrate njalo , futhi iyindlela yokwenza ikhodi egcina i- bitrate efanayo. Uma idatha yomsindo ifakwe ikhodi (nge- codec ), isamba esinqunyiwe sisetshenziswa, njenge-128, 256 noma 320 Kbps.
Inzuzo yokusebenzisa indlela yeCBR yukuthi idatha yomsindo ihamba ngokusheshisa (uma kuqhathaniswa neVBR). Kodwa-ke, amafayela adalwe awakhulumi kahle ngekhwalithi noma isitoreji njengoba kunjalo nge-VBR.
I-CBR iyasiza uma kuziwa kokusakaza amafayela we-multimedia. Uma ukuxhumeka kunqunyelwe ukukwenza nje kuphela, uthi, 320 Kbps, khona-ke i-bitrate njalo ye-300 Kbps ngomzuzwana noma ephansi ingaba nenzuzo kakhulu kuneyashintsha kulo lonke ukudluliselwa ngoba kungenzeka ukuthi liphakeme kunalokho okuvunyelwe.
Ukubhala nge-VBR
I-VBR isifushane kwe-bitrate eguquguqukayo futhi, njengoba ungacabanga, okuphambene ne-CBR. Yindlela yokwenza ikhodi eyenza i-bitrate yefayela elilalelwayo likhulise noma liyeke ngamandla. Lokhu kusebenza ngebanga lokukhomba; i-encoder ye-LAME, isibonelo, ingaba phakathi kuka-65 Kbps no-320 Kbps.
Njenga-CBR, amafomethi alalelwayo afana ne-MP3, iWMA, i- OGG , njll ukwesekwa kwe-VBR.
Inzuzo enkulu ye-VBR uma kuqhathaniswa ne-CBR iyinhloko ezwakalayo yokufaka usayizi wezinga isilinganiso. Ungakwazi ukufeza usayizi wefayili encane ngokufaka ikhodi ye-VBR kuneCBR ngenxa yendlela ye-bitrate eguquliwe kuye ngokuthi uhlobo lomsindo.
Isibonelo, i-bitrate izokwehliswa kakhulu ukuze izingxenye zomsindo zithule noma zinyene. Ukuze uthole izindawo eziyinkimbinkimbi zengoma equkethe ukuxuba kwama frequencies, i-bitrate izokwandiswa (kufika ku-320 Kbps) ukuqinisekisa ukuthi izinga elizwakalayo ligcinwa. Lokhu kuhluka kwe-bitrate kuzosiza ekunciphiseni isikhala sokugcina esidingekayo kuqhathaniswa ne-CBR.
Kodwa-ke, ukungalungi kwefayela le-VBR elifakwe ekhompyutheni kungukuthi kungenzeka ukuthi akuhambisani namadivayisi adala ase-elektroniki njengeCBR. Kuthatha isikhathi eside ukuhlanganisa umsindo usebenzisa i-VBR ngoba inqubo iyinkimbinkimbi.
Yikuphi Okufanele Ukhethe?
Ngaphandle kokuba uvinjelwe yi-hardware endala esekela kuphela amafomethi okulalelwayo afakwe nge-CBR, bese i-VBR ivame indlela ephakanyisiwe. Ukusekela i-VBR kumadivayisi we-hardware afana nama-MP3 abadlali, ama- PMP , njll, ajwayele ukushaya futhi alahleke, kodwa lezi zinsuku ngokuvamile ziyisici esivamile.
Njengoba kushiwo ngenhla, i-VBR ikunikeza ibhalansi engcono kakhulu phakathi kwekhwalithi kanye nosayizi wefayela. Ngakho-ke kungcono kumaphathekayo anesitoreji esinqunyiwe noma lapho ufuna ukusebenzisa ngokuphumelelayo ezinye izixazululo zokugcina ezifana ne- USB flash drive , amakhadi alula, njll.
