Kana iwe uchida kubvarura ma CD yako emimhanzi kune faira yakagadzirwa se MP3 , WMA , AAC , nezvimwewo, kana kuti unoda kutendeuka pakati pezvigadziro, zvinove pfungwa yakanaka kuziva CBR neVBR zvinorevei usati watanga.
Pasi pane chimiro pane izvo zvinyorwa zviviri izvi zvinorevei, maitiro avanoita sei, uye musiyano pakati pemakodhi maviri ekunyora.
Cherechedza: CBR uye VBR zvakare mabhiizo emamwe mazwi akafanana neCyplay akaitwa Archived Comic Book mafaira uye rekodi yebhoti yepamusoro , asi haavi nechokuita nekodhidhi sezvinotsanangurwa pano.
CBR Encoding
CBR inomirira bitrate nguva dzose , uye iyo inzira yekodhi inochengetedza bitrate zvakafanana. Kana dhidhiyo yemodhi ikakodhwa (ne codec ), kukosha kwakagadzirirwa kunoshandiswa, kufanana ne 128, 256 kana 320 Kbps.
Kubudirira kwekushandisa nzira yeCBR ndeyokuti data audio inowanzoshanda nokukurumidza (inofananidzwa neVBR). Zvisinei, mafaira akasikwa haana kunyatsogadziriswa nehutano maererano nekuchengetedza sezvinoitika kune VBR.
CBR inobatsira kana iri kuuya pakushambadzira mafirimu emafaira. Kana kubatanidzwa kuri kukwana kungoita chete, ichiti, 320 Kbps, ipapo bhitrate yenguva dzose ye 300 Kbps pachipiri kana pasi inogona kuva yakakosha kudarika imwe yakashandura mukati mekuparidzirwa sezvo inogona kuenderera mberi kupfuura yakabvumidzwa.
VBR Encoding
VBR inopfupika kuti ishandrate yakasiyana uye, sezvamungafungidzira, zvakasiyana neCBR. Iyo nzira yekodhidhi inoita kuti bitrate yehurukuro inoteerera iwedzere kuwedzera kana kuderera. Izvi zvinoshanda nechinangwa chakasiyana; iyo LAME encoder, somuenzaniso, inogona kuva pakati pe 65 Kbps uye 320 Kbps.
Kufanana neCBR, mavara mavara akadai se MP3, WMA, OGG , etc kutsigira VBR.
Kubatsira kukuru kweVBR kana uchienzaniswa neCBR ishuhu yakanakisisa yekuisa huwandu hwehuwandu. Iwe unogona kazhinji kupedza zviduku zvemafaira wepodhi kuburikidza nekodhidza mutauro neVBR pane CBR nokuti nzira yekatrate inoshandiswa zvichienderana nemamiriro ezwi.
Semuenzaniso, bitrate ichave yakanyanya kuderedzwa kuti zvive zvinyararire kana zvakanyorovesa zvenziyo. Kune dzimwe nzvimbo dzakaoma dzenziyo ine musanganiswa wezvipembenene, bitrate ichawedzerwa (kusvika ku 320 Kbps) kuti uone kuti unhu hwakanaka hunochengeterwa. Izvi zvakasiyana mu bitrate zvichadaro, zvinobatsira kubatsira kuderedza nzvimbo yekuchengetedza inoda kuenzaniswa neCBR.
Zvisinei, kusagadzikana kweVBR kwakasungirirwa mafaira ndeyokuti vangave vasingawirirani nemagetsi ekare akadai seCBR. Zvinotora nguva yakareba kuti dzikwanise kunyatsonyoresa kushandisa VBR nokuti nzira yacho yakaoma kunzwisisa.
Ndeupi Waunofanira Kusarudza?
Kunze kwekuti iwe uchingorambidzwa nehare yekare yehu hardware iyo inongobatsira chete mafaira ehurukuro akanyorwa neCBR, ipapo VBR inowanzogadzirirwa nzira. Kutsigira kweVBR mune zvigadzirwa zve hardware se MP3 player, PMPs , nezvimwewo, zvakashandiswa kurohwa uye kushaikwa, asi mazuva ano kazhinji inowanzoenderana.
Sezvambotaurwa pamusoro apa, VBR inokupa zvakanakisisa pakati pehuwandu nehuwandu hwefaira. Saka zvakanakisisa kune zvinyorwa zvisingakwanisi kuchengetedza kana kuti iwe unoda kushandisa zvakadini zvimwe zvigadziro zvekuchengetedza seSc flash flash drives , makadhi e-flash, nezvimwewo.
