AVI ukuba AAC Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndiyikhupha njani i-audio kwifayili yam AVI njenge AAC?

Layisha phezulu ifayili AVI 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. AVI yiMicrosoft's Audio Video Interleave, enikezelwe ngowe-1992 phezulu kwe RIFF chunk format - enye yezinto ezidala ezigcinwe zihlala zijikeleza. I-AAC yiNkqubo yoKhuseleko lwesandi esiPhambili, emiselwe ngo-1997 njenge-MPEG-2 Inxalenye ye-7 kwaye icwangciswe ngokucacileyo ukubuyisela i-MP3.

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. Iifayili ze-AVI zingaphambili kunee-codecs eziphambili: lindele i-MPEG-4 Inxalenye ye-2 (DivX/Xvid), i-Motion JPEG okanye iifayili ezingenakucothayo ezingenakucothayo kunokuba i-H.264. 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 AVI, 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.

Ingaba ifayili enkulu kakhulu AVI iyakulayishwa ngokuphumelelayo?

Ii-akhawunti ezikhululekileyo zifikelela kwi-100 MB kwifayili nganye, AVI amacebo ahamba phezulu ngenxa yokuba ifomati ihambisa i-chunk nganye ebalulekileyo engaphezulu kwe-data yevidiyo. I-Premium iphakamisa i-cap ngokucacileyo. Ukuba ifayile ihlukaniswe ibe ziinxalenye ezilinganisayo ngenxa yefomati ye-ceiling, ulayishe nganye nganye kwaye zithathwe njengemisebenzi enye. I-AVI ayinakuxhaswa kwe-codecs ekutsha, i-frame rate etshintshayo, izihloko ezimfutshane ezicocekileyo okanye iifayile ezingaphezulu kwe-4 GB ngaphandle kwe-hacks, kwaye i-chunk nganye i-overhead ikhupha ifayili.

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-AVI 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 AVI 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.
