DivX → 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. Imixholo ye-DivX yi-MPEG-4 Inxalenye ye-2 yevidiyo, eqhelekileyo ijikelezwe kwi-AVI, ene-MP3 okanye i-AC-3 yesandi ecaleni kwayo. I-MP3 ilahlekile: imodeli ye-psychoacoustic isusa ukuphindaphinda indlebe ayikwazi ukuqaphela, ihlala kwi-128 ukuya kwi-320 kbps.

Ewe, kwaye yimpumelelo epheleleyo ngaphezulu kwe DivX, 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.

Ijika ezantsi kwi-stereo, kuba MP3 ayinayo indlela esebenzayo ye-multichannel. Ukudibanisa ezantsi kusetyenziswa izilinganisi eziqhelekileyo ukuze unxibelelwano lwe-center-channel luhlale lucacileyo kwaye izijikelezi-ndawo zidityanisiwe kwinqanaba eliphantsi. Nantoni na exhomekeke kukubeka isiqhagamshelanisi esikhethekileyo iphela xa oku kwenzeka. MP3 igqityiwe nge AAC ne Opus kwinqanaba ngalinye le-bitrate, ayikwazi ukugcina ngaphezulu kweendawo ezimbini eziluncedo, kwaye ihlala idibanisa ulibaziso oluncinci lwe-encoder.

Ii-akhawunti ezikhululekileyo zifikelela kwi-100 MB kwifayili nganye, DivX 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-DivX ifuna ukuphindaphindwa kabini kwe-bitrate ye-H.264 yomgangatho ofanayo kwaye ayinayo indlela ye-HDR, 10-bit umbala okanye ugqibo ngaphezulu kwe-1080p.

I-bitrate emiselweyo ye-lossy MP3 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.

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

Ngokungagqibekanga ewe — 48 kHz yesandi kwi DivX yakho ihlala i-48 kHz kwi-MP3 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.

Ewe — susa isiqulathi seefayili ze DivX 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.

Ukuba i DivX ithatha isahluko okanye i-metadata yokuhamba, siyakopa isihloko / umculi / imihlaba ye-albham kwi MP3 isiqulathi seefayili. Ukuba akunjalo, i MP3 iza ngaphandle ingaphawulwanga — sebenzisa umhleli we-tag (Mp3tag, Picard) emva korhwebo ngaphandle lokufaka i-tag eninzi.

I-audio demux + encode ikhawuleza - iqhelekileyo 5 ukuya kwi 15% yobude bomthombo. I-1-iyure DivX → MP3 igqiba kwimizuzu emithathu ukuya kwi 9 kwindlela eqhelekileyo yokuhambisa; i-Premium parallelism icima oku ngaphezulu kwimisebenzi yeqela.

Akukho 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 ukunika ulawulo oluchanekileyo lwenqanaba le-waveform.
