M4A kuya AC3 Imibuzo Evame Ukubuzwa Yokuguqulwa

Ngiguqula kanjani umsindo we-M4A ube yi-AC3 ngaphandle kokulahlekelwa yikhwalithi?

Layisha phezulu i-M4A file futhi umguquli wethu ukhetha i-AC3 codec / bitrate combination efana ne-source. Injongo engalahleki (AC3 = WAV / FLAC / ALAC) igcina yonke isampula; injongo elahlekile (AC3 = MP3 / AAC / OGG) iphutha liyi-192 kbps ecacile kuma-earphones amaningi.

Yini i-bitrate i-AC3 isebenzisayo?

Iphutha 192 kbps ku-lossy AC3; idlula-nge-lossless AC3. Idlula ku-320 kbps ku-audiophile noma ku-96 kbps ku-voice / podcast. Ukhetho lushintsha ubukhulu behele ku-audible fidelity ku-bitrates ephansi kakhulu.

Ingabe ukusuka ku-M4A kuya ku-AC3 kuzonciphisa izinga lami lomsindo?

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

Yebo — khipha isibaya se-M4A 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-AC3 izogcina isilinganiso esifanayo sesampula njenge-M4A?

Ngokuzenzakalela yebo (48 kHz M4A → 48 kHz AC3). Uma ufuna ukuncipha kwesampula ukuze kusebenze (isibonelo 96 kHz → 44.1 kHz ukushaya i-CD) isinqumo esiphezulu sesampula-rate sikwenza lokhu ngesampula esezingeni eliphakeme.

Ingabe ngizolungisa umsindo ku-M4A kuya ku-AC3?

Yebo — ukhetho lokujwayelekile-lokujwayelekile lufaka ITU-R BS.1770 / EBU R128 ukujwayelekile ku-AC3 output, lubeka inhloso -14 LUFS (isilinganiso sokusakaza) noma -16 LUFS (isilinganiso sepodcast). Kuhle uma uguqula amabhayisikobho ngezinga lokuphatha elihlukile.

Ingabe i-AC3 izodlala ku-stereo yemoto yami / iPod / Sonos?

MP3 idlala emhlabeni wonke. AAC idlala ku Apple, Android, Sonos. FLAC idlala ku Sonos ne Android, ngaphezu kahle ku iPods edlule. WAV idlala konke kodwa kukhulu. Izinketho eziphezulu zifaka idivayisi imise izinhloso ezivamile.

Ingabe ihele lami M4A liyimfihlo ngesikhathi sokuguqulwa?

Yebo — amafayela alayishwe M4A aqhubekelwa phambili emisebenzini ehlukanisiwe futhi acishwe ngaphakathi kwemizuzu. Asikwazi ukudlala, ukugcina, noma ukuhlanganisa okuqukethwe kwesandi.

Ithatha isikhathi esingakanani ukushintsha M4A yehora elilodwa kuya kuAC3?

I-codec efanayo iphinde i-mux: imizuzwana engu-10-30. Yenza kabusha i-codec eyahlukileyo: ngokuvamile 10-20% yesikhathi somthombo, ngakho-ke ihora elilodwa M4A → AC3 liphele ngemizuzu engu-6-12.

Kungani ihele AC3 likhulu / lihlanzekile kunalelo M4A?

Akukho shintsho lokufinyelela oluzenzakalelayo kwenziwa ngaphandle kokuthi uvule isinqumo sokujwayelekile. Uma ubona ushintsho lwezinga, umdlali wakho wesandi noma ithala lemithombo ingasebenzisa i-ReplayGain noma ukuguqulwa kwe-track-by-track ku-playback — hhayi nathi.
