WebM ukuba MP2 Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndiyikhupha njani i-audio kwifayili yam WebM njenge MP2?

Layisha phezulu ifayili WebM kwaye umguquli ukhupha umsinga wesandi, emva koko uguqula ukukhowuda ku MP2. Akukho sibini sevidiyo esidlulayo - umkhondo obonakalayo ulahliwe ngokukhawuleza ngoko ke ukutywina kukhawuleza kakhulu kune-re-encoding epheleleyo. I-WebM yinxalenye encinci eqinileyo ye-Matroska epapashwe yiGoogle ngo-2010 ekhethekileyo ukunika i-HTML5 ividiyo isiqulathi seefayili esingenazo iirhafu. I-MP2 yi-MPEG-1 Umphezulu Womsindo II, umphezulu ongaphambili kwe-MP3 wavela waba ngumlinganiselo womsebenzi womsindo we-DVB kunye ne-DAB yosasazo.

Ingaba ukutshintsha WebM ukuya ku MP2 kujikelezo lwesibini lokucinezela okulahlekileyo?

Ewe, kwaye kufanelekile ukucwangcisa. Zonke iifomati zilahlekile, ngoko ke i MP2 encoder isebenza kwisandi esisele sidlula kwindlela enye ye psychoacoustic, kwaye izigqibo zayo zidibanisa iseti yokuqala. Kwi 192 kbps okanye ngaphezulu isiphumo sihlala sicacile kubaninzi bokuziva. Ukuba une master engalahleki naphi na, ukukopela i MP2 ukusuka apho endaweni yoko ikhusela i pass kabini ngokupheleleyo. I-WebM imiselwe ukuba incinci: i-VP8 okanye i-VP9 ividiyo (i-AV1 ngoku isasazeka) ene-Vorbis okanye i-Opus isandi, akukho nto enye. MP2 ilahlekile kodwa isebenzisa ibanki yecebo lokucoca ulwelo elilula kune MP3, eqhelekileyo isebenza kwi 192 ukuya kwi 384 kbps.

I-MP2 ekhutshiweyo isebenzisa i-bitrate yesandi eyiphi?

Ingaba i-MP2 yesandi igcina umyinge wesikhokelo ongaphambili?

Ngokungagqibekanga ewe — 48 kHz yesandi kwi WebM yakho ihlala 48 kHz kwi MP2 imveliso. Ukukhupha i-CD okanye ukulungelelanisa umdlali ovela kwixesha elidlulileyo ungakhupha isampuli ukuya kwi-44.1 kHz ngesampula-yexabiso eliphantsi; isampuli ephindaphindwayo iphezulu kwi-SoX-grade.

Ndingayikhupha isandi ukusuka kwiifayili ezininzi WebM ukuya kwi MP2 kwiqela elinye?

Ewe - shiya isiqulathi seefayili se WebM iifayili kwaye sikhuphe umsindo ngokuthe tye. Abasebenzisi abaphezulu bafumana abasebenza ngokuthe tye abaninzi; kwifayile ye-50 iqela lento le yinto eyahlukileyo phakathi kwemizuzu emibini kunye nemizuzu elishumi elinesibini.

Ithatha ixesha elingakanani ukutsala i-MP2 yesandi ukusuka kwi-1-iyure i-WebM?

I-audio demux + encoding ikhawuleza - iqhelekileyo 5 ukuya kwi 15% yobude bomthombo. I 1- iyure WebM → MP2 igqiba kwi 3 ukuya kwi 9 imizuzwana kwindlela eqhelekileyo yokuhambisa; Uthelekiso oluphezulu lukhupha oku ngaphezulu kwimisebenzi yeqela.
