MP3 Encoding Chaw
Taw qhia
Cov hom ntawv MP3 yog cov suab nrov nrov tshaj plaws uas siv niaj hnub no thiab tau nyob ib ncig ntawm kaum xyoo. Nws txoj kev vam meej muaj peev xwm yog vim yog nws txoj kev sib haum xeeb. Txawm nrog txoj kev ua tiav no, tseem muaj cov cai tseem ceeb koj yuav tsum paub ua ntej tsim MP3 ntaub ntawv. Tej yam nram qab no yuav qhia koj ib lub tswv yim txog kev kho koj qhov kev xaiv qhov kev ntsuam xyuas kom pom tau.
Lub suab qhov zoo
Yuav kom xaiv qhov zoo encoding qhov tseem ceeb koj thawj zaug tau xav txog qhov xwm ntawm lub suab qhov chaw. Piv txwv li, yog hais tias koj yog ib qho suab txias ntawm cov ntaub ntawv kaw suab los ntawm ib daim kab xev analog thiab siv cov khoom siv ntau tshaj plaws los ntawm qhov chaws ces qhov no yuav pov tseg ntau qhov chaw cia. Yog tias koj xav hloov cov ntaub ntawv MP3 uas muaj ib qho ntawm 96 kbps rau hauv ib qho nrog 192kbps bitrate ces tsis muaj kev txhim kho rau qhov zoo yuav tshwm sim. Yog vim li cas rau qhov no yog tias tus thawj yog 32kbps xwb thiab yog li txhua yam siab tshaj qhov no yuav cia li nce cov ntaub ntawv me me thiab yuav tsis txhim kho lub suab daws teeb meem.
Ntawm no yog qee qhov kev txiav me ntsis uas koj yuav tau sim nrog:
- 32 kbps - Cov ntaub ntawv kaw suab / suab paj nruag (analog).
- 128 rau 192 kbps - Ripping lem ntawm CD.
- 192 mus rau 320 kbps - Cov ntawv sau suab paj nruag (cov uas muaj qhov dav spectrum ntawm frequencies, xws li cov suab paj nruag classical piv txwv).
Lossy rau Lossy
Hom ntawv MP3 yog hom ntawv sau los yog hloov ua lwm hom ntawv (los yog lwm MP3) tsis pom zoo. Txawm hais tias koj sim hloov mus rau ib tug ntau bitrate, koj tseem yuav poob poob zoo. Nws yog qhov zoo tshaj plaws los tawm hauv qhov tseem ceeb thaum nws yog, tshwj tsis yog koj xav txo qhov chaw cia thiab tsis txhob poob siab hauv lub suab daws teeb meem.
CBR thiab VBR
Ntev bitrate ( CBR ) thiab kuj nce mentsis bitrate ( VBR ) yog ob qho kev xaiv uas koj tuaj yeem xaiv tau thaum encoding ib qho ntaub ntawv MP3 uas ob leeg muaj lawv cov kev txawj thiab qaug zog. Ua ntej koj txiav txim siab seb puas yuav siv CBR los yog VBR koj yuav tsum xub xav txog seb koj yuav mloog lub suab li cas. CBR yog qhov chaw tsis muaj teeb meem uas muaj feem ntau tshaj MP3 decoders thiab kho vajtse, tiam sis tsis ua cov ntaub ntawv zoo tshaj plaws MP3. Xwb, VBR ua cov ntaub ntawv MP3 uas yog qhov ua kom zoo rau ob qho tib si. VBR tseem yog qhov zoo tshaj plaws tov, tiam sis nws tsis yog ib qho uas txuam nrog kho vajtse thiab cov MP3 decoders.
