Ndiyikhupha njani i-audio kwifayili yam MKV njenge M4A?

Layisha phezulu ifayili MKV kwaye umguquli ukhupha umsinga wesandi, emva koko uguqula ukukhowuda ku M4A. Akukho sibini sevidiyo esidlulayo - umkhondo obonakalayo ulahliwe ngokukhawuleza ngoko ke ukutywina kukhawuleza kakhulu kune-re-encoding epheleleyo. MKV yi Matroska, isiqulathi esivuliweyo esidweliswe ngowe-2002 ngaphandle kokungasebenzisi ilayisensi okanye uthintelo oluphezulu olunokunqumla.

Ingaba ukutshintsha MKV ukuya ku M4A kujikelezo lwesibini lokucinezela okulahlekileyo?

Ewe, kwaye kufanelekile ukucwangcisa. Zonke iifomati zilahlekile, ngoko ke i M4A 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 M4A ukusuka apho endaweni yoko ikhusela i pass kabini ngokupheleleyo. I-MKV ayisebenzisi i-codec: H.264, HEVC, VP9 ne-AV1 ividiyo ihlala ikhululekile ecaleni kwe-AAC, FLAC, Opus, DTS okanye i-Dolby audio kwifayili enye.

Ndingayiphawula i M4A ngeenkcukacha zomculi ne-albham?

Ewe, kwaye yimpumelelo epheleleyo ngaphezulu kwe MKV, eyona ingekho naphi na ethembekileyo ukugcina nayiphi na. M4A ithatha isihloko, umculi, i-albham, unyaka, inani lengoma kunye nobugcisa bokuqhoboshela okufakwe kwisiqulathi seefayili, ngoko ithala leencwadi lengoma liyifaka ngokuchanekileyo ngaphandle kokuhamba ngesandla. I-M4A igcina i-data ye-meta eninzi ye-iTunes-style, izihloko kunye nomsebenzi womzobi okhuselekileyo, kwaye yifomati yesandi esemthethweni kwisixhobo se-Apple.

Ukuya olungalahleki → olungalahleki akuyi kubuyisela inkcukacha esele zilahlekile.

Ingaba i-M4A yesandi igcina umyinge wesikhokelo ongaphambili?

Ngokungagqibekanga ewe — 48 kHz yesandi kwi MKV yakho ihlala 48 kHz kwi M4A 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 MKV ukuya kwi M4A kwiqela elinye?

Ewe - shiya isiqulathi seefayili se MKV 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.
