AVI → MP3

Ewe, kwaye kufanelekile ukucwangcisa. Zonke iifomati zilahlekile, ngoko ke i MP3 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 MP3 ukusuka apho endaweni yoko ikhusela i pass kabini ngokupheleleyo. Iifayili ze-AVI zingaphambili kunee-codecs ezitsha: lindele i-MPEG-4 Inxalenye ye-2 (DivX/Xvid), i-Motion JPEG okanye iifayili ezingenakucothayo ezingenakucothayo kunokuba i-H.264. I-MP3 ilahlekile: imodeli ye-psychoacoustic isusa ukuphindaphinda indlebe ayikwazi ukuqaphela, ihlala kwi-128 ukuya kwi-320 kbps.

Ewe, kwaye yimpumelelo epheleleyo ngaphezulu kwe AVI, eyona ingekho naphi na ethembekileyo ukugcina nayiphi na. MP3 ithatha isihloko, umculi, i-albham, unyaka, inani lengoma kunye nobugcisa bokuqhoboshela okufakwe kwisiqulathi seefayili, ngoko ithala leencwadi lengoma liyifaka ngokuchanekileyo ngaphandle kokuhamba ngesandla. Akukho nto ibetha iMP3 ekusebenzeni kwayo - iistereo zemoto, izixhobo zegym, iiDAPs kunye nezixhobo zekhompyutha ezineminyaka engama-20 ubudala zonke zifunda ngaphandle kwemibuzo.

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 ezimdaka okanye iifayile ezingaphezulu kwe-4 GB ngaphandle kwe-hacks, kwaye i-chunk nganye i-overhead ikhupha ifayili.

Ixabiso le-bit elimiselweyo le-lossy MP3 yi-192 kbps, ebonisa ngaphaya iingoma. Ungayicima i-320 kbps (audiophile) okanye i-96-128 kbps (ulizwi / ipodcast / ifayili encinci). Ixabiso le-bit eliphantsi livela kukhetho oluphambili phambi kokuba ucofe uguqule.

Ukuba MP3 ayilahleki (WAV, FLAC), yonke isampuli igcinwa ngokuchanekileyo. Ukuba MP3 ilahlekile (MP3, AAC, OGG, Opus), i MP3 codec iphinde icinezele umbhalo ovela kumbhalo - kwi-192 kbps isiphumo sicacile kuzo zonke izinto eziqukayo. Ukuya olungalahleki → olungalahleki akuyi kubuyisela inkcukacha esele zilahlekile.

Ngokungagqibekanga ewe — 48 kHz yesandi kwi AVI yakho ihlala 48 kHz kwi MP3 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.

Ewe - shiya isiqulathi seefayili se AVI 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.

Ukuba i AVI ithatha isithuba okanye i-metadata yokuhamba, sikopa isihloko / umculi / i-albham yemihlaba kwi MP3 isiqwenga. Ukuba akunjalo, i MP3 iza ngaphandle ingaphawulwanga - sebenzisa umhleli wephetshana elichazayo (Mp3tag, Picard) emva korhwebo ngaphandle lophawulo oluninzi.

I-audio demux + encoding ikhawuleza - iqhelekileyo 5 ukuya kwi 15% yobude bomthombo. I 1- iyure AVI → MP3 igqiba kwi 3 ukuya kwi 9 imizuzwana kwindlela eqhelekileyo yokuhambisa; Uthelekiso oluphezulu lukhupha oku ngaphezulu kwimisebenzi yeqela.

Ayikho kule sixhobo ngokuthe ngqo — khupha isandi esipheleleyo njenge MP3, emva koko sebenzisa /audio-trim/ okanye /audio-cutter/ ukucima icandelo. Umendo wenyathelo elinye uhlala ukhawuleza kunenkqubo edityanisweyo kwaye unika ulawulo oluchanekileyo lwe-waveform-level.

Ewe - imodeli yobumfihlo efanayo neyokuguqulwa ngalinye: abaqeshi ababekwe ngokukodwa, akukho kuhlaziyo lomuntu, ukucinywa okuzenzekelayo ngaphakathi kwemizuzu yokuphela. Ifestile yokugcina epheleleyo ikwi /privacy/.
