MKV ukuba AAC Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndiyikhupha njani i-audio kwifayili yam MKV njenge AAC?

Layisha phezulu ifayili MKV kwaye umguquli ukhupha umsinga wesandi, emva koko uguqula ikhowudi ibe yi AAC. Akukho sibini sevidiyo esidlulayo - irekhodi elibonakalayo lilahliwe ngokuzenzekelayo ngoko ke ukutywina kukhawuleza kakhulu kune-encoding epheleleyo. MKV yi Matroska, ibhokisi evulekileyo eyenziwe ngo 2002 ngaphandle kweengxaki zonikezelo lwelayisensi kunye nokungaphelelanga kwinto engayigcinayo. I-AAC yiNkqubo yoKhuseleko lwesandi esiPhambili, emiselwe ngo-1997 njenge-MPEG-2 Inxalenye ye-7 kwaye icwangciswe ngokucacileyo ukubuyisela i-MP3.

Ingaba ukutshintsha MKV ukuya ku AAC kujikelezo lwesibini lokucinezela okulahlekileyo?

Ewe, kwaye kufanelekile ukucwangcisa. Zonke iifomati zilahlekile, ngoko ke i AAC 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 AAC ukusuka apho endaweni yoko ikhusela i pass kabini ngokupheleleyo. MKV yi-codec-agnostic: H.264, HEVC, VP9 ne-AV1 ividiyo ihlala ikhululekile ecaleni kwe-AAC, FLAC, Opus, DTS okanye i-Dolby audio kwifayili enye. I-AAC ilahlekile kodwa isebenza kakuhle kune-MP3, kwaye iphatha ukuya kuthi ga kwi-48 yeendlela eziqhelekileyo kunokuba ifakwe ibhotile kuyilo lwestereo.

Ndingayiphawula i AAC ngeenkcukacha zomculi ne-albham?

Ewe, kwaye yimpumelelo epheleleyo ngaphezulu kwe MKV, eyona ingekho naphi na ethembekileyo ukugcina nayiphi na. AAC ithatha isihloko, umculi, i-albham, unyaka, inani lengoma kunye nobugcisa bokuqhoboshela okufakwe kwisiqulathi seefayili, ngoko ithala leencwadi lengoma liyifaka ngokuchanekileyo ngaphandle kokuhamba ngesandla. I-AAC ithetha ngokucacileyo ngakumbi kune-MP3 engaphantsi kwe-128 kbps kwaye yindawo emiselweyo yokulandela umkhondo wesandi kwi-MP4, YouTube, Apple Music kunye nokusasazwa.

I-AAC ekhutshiweyo isebenzisa i-bitrate yesandi ethini?

I-bitrate emiselweyo ye-lossy AAC yi-192 kbps, ebonisa ngaphaya kwengoma. Ungayicima i-320 kbps (audiophile) okanye i-96-128 kbps (ilizwi / ipodcast / ifayili encinci). I-bitrate esuka ezantsi ivela kwiinketho eziphambili phambi kokuba ucofe uguqule.

Ingaba ndiya kulahlekelwa umgangatho wesandi xa ndisuka kwi-MKV ukuya kwi-AAC?

Ukuba AAC ayilahleki (WAV, FLAC), isampuli nganye igcinwa ngokuchanekileyo. Ukuba AAC ilahlekile (MP3, AAC, OGG, Opus), i-AAC codec iphinda icinezele umbhalo wesandi - kwi-192 kbps isiphumo sicacile kuzo zonke iziqulatho. Ukuya kwi-lossy → ayilahleki akuzukubuyisela iinkcukacha ezisele zilahlekile.

Ingaba i-AAC yesandi igcina i-sample rate yangaphambili?

Ngokungagqibekanga ewe — 48 kHz yesandi kwi MKV yakho ihlala i-48 kHz kwi-AAC yemveliso. Ukukhupha i-CD okanye ukulungelelanisa umdlali okhoyo ungakhupha i-sample ukuya kwi-44.1 kHz nge-sample-rate dropdown; i-resampler ikwi-SoX-grade esezingeni eliphezulu.

Ndingayikhupha i-audio kwiifayili ezininzi MKV kwi AAC kwiqela elinye?

Ewe — susa isiqulathi seefayili ze MKV kwaye sikhuphe isandi ngokuthe tye. Abasebenzisi abaphezulu bafumana abasebenzi abathe tye abaninzi; kwifayili ye-50-batch le yinto eyahlukileyo phakathi kwemizuzu emibini kunye nemizuzu emihlanu.

Ingaba i-AAC iya kuphawulwa ngesihloko / umculi / i-metadata ye-albham?

Ukuba i MKV ithatha isahluko okanye i-metadata yokuhamba, siyakopa isihloko / umculi / imihlaba ye-albham kwi AAC isiqulathi seefayili. Ukuba akunjalo, i AAC iza ngaphandle ingaphawulwanga — sebenzisa umhleli we-tag (Mp3tag, Picard) emva korhwebo ngaphandle lokufaka i-tag eninzi.

Ithatha ixesha elingakanani ukutsala i-AAC yesandi ukusuka kwi-MKV yeyure?

I-audio demux + encode ikhawuleza - iqhelekileyo 5 ukuya kwi 15% yobude bomthombo. I-1-iyure MKV → AAC igqiba kwimizuzu emithathu ukuya kwi 9 kwindlela eqhelekileyo yokuhambisa; i-Premium parallelism icima oku ngaphezulu kwimisebenzi yeqela.

Ndingayikhupha icala le-MKV yesandi njenge-AAC?

Akukho kule sixhobo ngokuthe ngqo — khupha isandi esipheleleyo njenge AAC, emva koko sebenzisa /audio-trim/ okanye /audio-cutter/ ukucima icandelo. Umendo wenyathelo elinye uhlala ukhawuleza kunenkqubo edityanisweyo kwaye ukunika ulawulo oluchanekileyo lwenqanaba le-waveform.

Ingaba ifayili yam MKV ifihlakeleyo ngexesha lokukhupha isandi?

Ewe - imodeli yobumfihlo efanayo neyokuguqulwa ngasinye: abasebenzi ababekwe ngokuzimeleyo, akukho hlaziyo lomuntu, ukucinywa okuzenzekelayo ngaphakathi kwemizuzu yokugqitywa. Ifestile yokugcina epheleleyo ikwi /privacy/.

Kutheni le nto ifayili AAC ineengcambu ezingasebenziyo apho i MKV ikwisandi?

I-MKV iqulethe iingoma ezininzi zesandi kwaye i-demuxer ithathe i-stream engenanto okanye encedisayo. Sebenzisa isikhethi esiphambili "i-stream yesandi" ukukhetha i-stream 0, 1, 2 ngokucacileyo, okanye ubeke i-AAC kwisiqulathi seefayili esixhasa i-multi-track output (FLAC, OGG).
