Indlela yokuguqula M4A kuya AAC

Inyathelo 1: Ngenisa M4A amafayela usebenzisa inkinobho ngasentshonalanga noma ngoshicilela bese ushiya.

Inyathelo lesi-2: Chofoza inkinobho ethi 'Tshintsha' ukuqala ukuguqulwa.

Inyathelo 3: Qapha okuguqulwe AAC amafayela

M4A kuya AAC Imibuzo Evame Ukubuzwa Yokuguqulwa

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

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

Yini i-bitrate i-AAC isebenzisayo?

Iphutha 192 kbps ku-lossy AAC; idlula-nge-lossless AAC. 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-AAC kuzonciphisa izinga lami lomsindo?

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

Ingabe i-M4A kuya ku-AAC iguqula igcina ID3 / amathegi wedatha yemeta?

Yebo — isihloko, umculi, i-album, unyaka, inani lesiqalo, i-album art ifundwa kusuka ku-M4A futhi ibhalwe ngaphakathi kwe-AAC container (lapho i-AAC format ixhasa izixhumanisi, okungukuthi zonke ezijwayelekile zikwenza).

Ingabe ngingenza i-batch yokuguqula ama-M4A amafayela amakhulu ku-AAC?

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-AAC izogcina isilinganiso esifanayo sesampula njenge-M4A?

Ngokuzenzakalela yebo (48 kHz M4A → 48 kHz AAC). 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-AAC?

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

Ingabe i-AAC 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 kuAAC?

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 → AAC liphele ngemizuzu engu-6-12.

Kungani ihele AAC 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.

Ingabe ngiguqula M4A ukulayisha phezulu kwe-streaming ku-AAC?

Uma M4A i-download ayikhuselwanga (akukho DRM), yebo. Amafayela we-streaming abhalwe nge-DRM (Spotify, Apple Music) abhalwe nge-crypto ku-bit level futhi asikwazi ukuwaphatha. Ama-sources e-Bandcamp, SoundCloud download, nama-recordings asekhaya aguqulwa kahle.
