AC3 kuya M4A Imibuzo Evame Ukubuzwa Yokuguqulwa

Ngiguqula kanjani umsindo AC3 ube M4A ngaphandle kokulahlekelwa ukhwalithi?

Layisha phezulu ihele AC3 futhi umguquli wethu uzokhetha i M4A codec / i-bitrate ehambisanayo necebo. Injongo engalahleki (M4A = WAV / FLAC / ALAC) igcina yonke isampula; injongo elahlekile (M4A = MP3 / AAC / OGG) iphutha liyi-192 kbps ecacile yencwadi yezwi elikhulumayo kanye neminye imiculo.

Ingabe ukushintsha AC3 kuya ku M4A kuyingxenye yesithathu yokucindezela okulahlekile?

Yebo, futhi kufanelekile ukuhlela. Izifomethi zombili ziyi-lossy, ngakho-ke i-M4A encoder isebenza kusuka kumsindo osele udlulele engxenyeni eyodwa ye-psychoacoustic, futhi iziphakamiso zayo zihlanganisa isiqephu sokuqala. Ku-192 kbps noma ngaphezulu, imiphumela ihlala icacile kakhulu. Uma une-lossless master nganoma yikuphi, ukukopisha i-M4A kusuka kulo kunciphisa ukudluliswa okuphindiwe ngokuphelele. AC-3 yisandi esiningi esingenalutho, sivame u-5.1 ku-384 noma 448 kbps, nedatha yemeta yokuxoxa nokuhlanganiswa ngezansi. M4A igcina i-AAC emibonweni eminingi, noma i-Apple Lossless (ALAC) uma ivela ku-lossless rip.

Ingabe ngiyiphawula i M4A ngemininingwane yomuntu odlalayo ne-album?

Yebo, futhi kuyinzuzo engokoqobo ngaphezulu kwe AC3, engeke ikwazi ukugcinwa kuphi naphi. M4A ifaka isihloko, umculi, i-album, unyaka, inani le-track kanye ne-cover art efakwe ngaphakathi kwebhokisi, ngakho-ke i-library yomculo ifaka ngokulungile ngaphandle kokungena ngesandla. M4A igcina i-iTunes-style metadata, amasigaba kanye nemisebenzi yezandla egcwele, futhi iyifomethi yomsindo ovela ezweni lonke kunoma iyiphi idivayisi ye-Apple.

Ihele M4A lisebenzisa i-bitrate enjani?

Iphutha ngu-192 kbps ku M4A olahlekelwayo; udlulisa-nge- M4A ongenalutho. Nciphisa ku-320 kbps ku-audiophile noma ku-64-96 kbps ku-audiobooks ekhuluma-magama (icacile ku-voice, ihlukanise ubukhulu befayela ngamaphesenti).

Ingabe ukusuka ku AC3 kuya ku M4A kuzonciphisa ubunjani bomsindo wami?

Uma AC3 ilahlekelwa futhi M4A ayilahleki (isibonelo MP3 → WAV), ihele M4A alingcono kuna AC3 — awukwazi ukubuyisela imininingwane esele ilahlekile. Uma AC3 ilahlekelwa futhi M4A ayilahleki, cabanga ukuthi i-M4A codec izocindezela futhi; ku-192 kbps lokhu kucacile kunoma iyiphi ingxenye.

Ingabe i-AC3 kuya ku-M4A igcina amathegi we-ID3 / metadata?

Yebo — isihloko, umculi, i-album, unyaka, inani le-track, i-album art, nama-chapter markers (abalulekile kuma-audiobooks) afundwa kusuka ku-AC3 futhi abhalwe ku-M4A ibhokisi lapho i-M4A ifomu lixhasa amathegi. Ukwakhiwa kwe-audiobook M4B kuhamba-hamba ku-M4B ne-AAX → M4B output.

Ingabe ngingenza i-batch yokuguqula amahele angama-AC3 abe M4A?

Yebo — susa isibaya se AC3 amafayela ngaphakathi futhi sizoziphatha ngokufanayo. I-Premium inemisebenzi eminingi efana ne-parallel futhi akukho lutho oluphezulu lwesayizi yefayela ngalinye, ngakho-ke i-500-file batch iphele ngemizuzu endaweni yamahora angama-10.

Ingabe i-M4A izogcina isilinganiso esifanayo sesampula njenge-AC3?

Ngokuzenzakalela yebo (48 kHz AC3 → 48 kHz M4A). Uma ufuna uku-downsample ukuhambisana (isibonelo 96 kHz → 44.1 kHz yokushaya i-CD) isinqumo esiphezulu sesampula-rate sikwenza lokhu ngekhwalithi ephezulu yoku-resamply.

Ingabe ngizolungisa umsindo ku-AC3 kuya ku-M4A?

Yebo — ukhetho lokujwayelekile-lokujwayelekile lufaka ITU-R BS.1770 / EBU R128 ukujwayelekile ku M4A kuphuma, libhekisa ku -14 LUFS (isizinda sokushayela), -16 LUFS (isizinda sepodcast), noma -23 LUFS (isizinda sencwadi yezwi). Kuhle uma uguqula amabhayisikobho ngezinga lokuphatha elihlukile.

Ingabe i-M4A izodlala kwi-stereo yemoto yami / i-iPod / i-app yencwadi yezwi?

MP3 idlala emhlabeni wonke. AAC idlala ku Apple, ngaphezu Android, Sonos. FLAC idlala ku Sonos ne Android, ngaphezu kahle ku iPods edlule. M4B audiobooks dlala ngesigaba ukuzulazula ku iOS Books, Audiobookshelf, kanye Smart Audiobook Player. Izinto ezikhethwayo ezisezingeni eliphezulu zifaka idivayisi imise.

Ingabe ihele lami AC3 liyimfihlo ngesikhathi sokuguqulwa?

Yebo — amafayela alayishwe phezulu AC3 aqhubekelwa phambili abasebenza ngokuzimela futhi acishwe ngaphakathi kwemizuzu. Asikwazi ukudlala, ukugcina, noma ukuhlanganisa okuqukethwe kwesandi. Kubalulekile kakhulu uma usebenza nama-library wencwadi yesandi.

Ingabe kuthatha isikhathi esingakanani ukushintsha i-audiobook yehora elilodwa AC3 iye ku-M4A?

I-codec efanayo iphinde i-mux: 10-30 imizuzwana. Yenza kabusha i-codec eyahlukileyo: 10-20% yesikhathi somthombo, ngakho i-audiobook yehora elilodwa liphele ngemizuzu engu-60-120. Ama-chapter markers ahlala ehamba futhi ahlukaniswe ngokuhlanzekile.
