Txhawm rau rub koj cov nkauj CDs rau ib hom suab zoo li MP3, WMA, lossis AAC, lossis hloov pauv ntawm hom ntawv, nws yog lub tswv yim zoo kom paub seb CBR thiab VBR txhais li cas ua ntej koj pib. Peb piv ob txoj kev encoding no kom koj tuaj yeem xaiv qhov zoo tshaj plaws rau koj cov nkauj sau.
- Nyob zoo.
- Guaranteed dua cov ntaub ntawv zoo.
- Quicker encoding.
- Wideer compatibility.
- cov ntaub ntawv me dua.
- siv tau ntau dua ntawm qhov chaw cia.
- txo qis qis hauv qhov zoo.
- Tau muaj kev txhawb nqa tsawg dua.
Ntau yam cuam tshuam rau qhov zoo ntawm koj lub tsev qiv ntawv suab paj nruag digital. Bitrate yog ib qho ntawm lawv. Txawm hais tias koj tab tom nrhiav kom tau txais qhov zoo tshaj plaws rips lossis koj xav ua kom qhov chaw siab tshaj plaws ntawm koj lub xov tooj ntawm tes, nws yog ib qho tseem ceeb kom ntsuas koj cov kev xaiv hauv kev xaiv tus bitrate.
CBR Encoding Pros and Cons
- Set quality.
- Kev tswj hwm lub suab zoo.
- Zoo rau multimedia.
-
Yuav tsum muaj kev sib txuas los txhawb nws.
- Inflexible.
CBR stands rau qhov bitrate tas li thiab yog ib txoj kev encoding uas ua kom tus bitrate tib yam. VBR, ntawm qhov sib txawv, yog qhov sib txawv me ntsis. Thaum cov ntaub ntawv suab raug encoded los ntawm tus codec, tus nqi ruaj khov yog siv, xws li 128, 256 lossis 320 Kbps.
Feem ntau, qhov bitrate siab dua, qhov zoo ntawm lub suab.
Qhov zoo ntawm kev siv CBR txoj kev yog cov ntaub ntawv suab feem ntau ua haujlwm sai dua piv rau lwm txoj hauv kev. Txawm li cas los xij, cov ntaub ntawv uas tau tsim tsis zoo rau qhov zoo-tiv thaiv-kho, ib yam li VBR.
CBR muaj txiaj ntsig zoo rau kev xa tawm cov ntaub ntawv multimedia. Yog tias qhov kev sib txuas tau txwv tsuas yog ua tau zoo ntawm 320 Kbps, qhov tsis tu ncua ntawm 300 Kbps ib ob lossis qis dua yog qhov muaj txiaj ntsig ntau dua li qhov hloov pauv thoob plaws hauv kev sib kis txij li nws tuaj yeem mus siab dua qhov tau tso cai.
VBR Encoding Pros and Cons
-
Cov ntaub ntawv me dua.
- Kev txo qis hauv bitrate.
- Ntau dua hauv ntau qhov xwm txheej.
- Kev txo qis hauv qhov zoo.
- Less widely supported.
- Nyob rau encode.
VBR tso cai rau tus bitrate ntawm cov ntaub ntawv suab kom dynamically nce lossis txo qis hauv lub hom phiaj. Piv txwv li, LAME encoder sib txawv ntawm 65 Kbps thiab 320 Kbps. Zoo li CBR, suab tawm tswv yim xws li MP3, WMA, thiab OGG txhawb VBR.
Qhov zoo tshaj plaws ntawm VBR thaum piv rau CBR yog lub suab zoo rau cov ntaub ntawv loj piv. Feem ntau koj tuaj yeem ua tiav cov ntaub ntawv me me los ntawm kev xa suab nrog VBR es tsis yog CBR vim tias txoj kev hloov pauv hloov pauv nyob ntawm qhov xwm txheej ntawm lub suab.
Tus bitrate txo rau qhov ntsiag to lossis ntsiag to ntawm ib zaj nkauj. Rau ntau qhov chaw ntawm ib zaj nkauj uas muaj kev sib xyaw ntawm ntau zaus, tus bitrate nce (txog 320 Kbps) los xyuas kom meej lub suab zoo. Qhov kev hloov pauv no hauv tus nqi qis txo qhov chaw cia khoom xav tau piv rau CBR.
Txawm li cas los xij, qhov tsis zoo ntawm VBR cov ntaub ntawv encoded yog tias lawv yuav tsis sib haum nrog cov khoom siv hluav taws xob qub xws li CBR. Nws kuj yuav siv sij hawm ntev dua los encode suab siv VBR vim cov txheej txheem nyuaj dua.
Koj Yuav Tsum Xaiv Qhov twg?
Tshwj tsis yog tias koj tau txwv los ntawm cov khoom qub qub uas tsuas yog txhawb nqa audio formats encoded siv CBR, ces VBR yog txoj kev pom zoo. Kev them nyiaj yug rau VBR hauv cov khoom siv kho vajtse xws li MP3 players thiab PMPs tau raug ntaus thiab nco, tab sis hnub no nws feem ntau yog tus qauv.
VBR muab koj qhov sib npaug zoo tshaj plaws ntawm qhov zoo thiab cov ntaub ntawv loj. Yog li ntawd nws yog qhov zoo tagnrho rau cov khoom siv uas muaj qhov txwv cia lossis qhov chaw koj xav kom siv tau zoo ntawm lwm cov kev daws teeb meem xws li USB flash drives lossis flashcards.
