M4A kuya AAC Imibuzo Evame Ukubuzwa Yokuguqulwa

Ngiguqula kanjani umsindo M4A ube AAC ngaphandle kokulahlekelwa ukhwalithi?

Layisha phezulu ihele M4A futhi umguquli ukhetha i-AAC codec ne-bitrate ukufana nomsuka. Ukungabi naphutha AAC (WAV / FLAC / ALAC) ugcina yonke isampula nge-bit-identical; ukungabi nalutho AAC (MP3 / AAC / OGG / Opus) kumiswa ku-192 kbps okucacile kuma-earphones amaningi.

Yini i-bitrate ongayisebenzisa ihele elivela ku-AAC?

Iphutha ngu-192 kbps ku AAC olahlekelwayo; ukudluliswa-kwe- AAC okungalahleki. Nciphisa ku-320 kbps ku-audiophile noma ku-96 kbps ku-voice / podcast. Ukhetho lushintsha ubukhulu behele ku-audible fidelity; ngaphansi kuka-96 kbps olahlekelwayo, ama-artefacts abonakala emculo.

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

Uma M4A ilahlekelwa futhi AAC ayilahleki (isibonelo MP3 → WAV), AAC ayingcono kuna M4A — awukwazi ukubuyisela imininingwane elahlekile. Uma M4A ilahlekelwa futhi AAC ayilahleki, i-AAC codec icindezela futhi; ku-192 kbps imiphumela icacile kunoma iyiphi ingxenye.

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

Yebo — isihloko, umculi, i-album, unyaka, inani lesiqalo, nesithombe se-album zifundwa kusuka ku M4A isitoreji futhi zibhalwe ku AAC isitoreji lapho ifomu lixhasa amathegi. Zonke izimo ezijwayelekile (MP3, AAC, FLAC, OGG) ziphatha amathegi kahle; i-WAV engaqondakali ayisebenzi.

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

Yebo — susa 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?

Ngephutha yebo — 48 kHz M4A ihlala 48 kHz ku AAC. Uma ufuna ukusatshalaliswa ngezansi ukuze kusebenze (96 kHz → 44.1 kHz ukushaya i-CD), isinqumo sesampula-sayizi sifaka ukusatshalaliswa okusezingeni eliphezulu kuleyo ngxenye yokungenisa ikhodi.

Ingabe ngizolungisa umsindo uma ngiguqula M4A ku AAC?

Yebo — ukhetho lokujwayelekile-lokujwayelekile lufaka ITU-R BS.1770 / EBU R128 ukujwayelekile ku AAC, lubeka inhloso -14 LUFS (isizinda sokushayela) noma -16 LUFS (isizinda sepodcast). Kuhle uma kuhlanganiswa amabhayisikobho aqeqeshiwe ezingeni ezahlukene.

Ingabe AAC yami izodlala ku-car stereo, iPod, ne-Sonos?

MP3 idlala kuwo wonke amadivayisi. I-AAC idlala ku-Apple, ku-Android, ne-Sonos. I-FLAC idlala ku-Sonos ne-Android kodwa ayikho ku-iPods edlule. I-WAV idlala kuwo wonke amadivayisi kodwa inamandla amakhulu. Imenyu yokudonsa yedivayisi ethuthukisiwe ikhetha i-AAC codec elungele i-hardware yakho efanele.

Ingabe ihele lami M4A liyimfihlo ngesikhathi sokuguqulwa ku AAC?

Yebo — amafayela alayishwe phezulu M4A aqhubekelwa phambili emisebenzini ehlukanisiwe futhi acishwe ngaphakathi kwemizuzu. Asikwazi ukudlala emuva, ukugcina isikhathi eside, noma ukuhlanganisa okuqukethwe kwesandi. Ifasitela lokugcinwa okuphelele likhona ku /privacy/.

Ingabe kuthatha isikhathi esingakanani ukushintsha ihora le-M4A libe AAC?

I-codec efanayo iphinde i-mux: 10 kuya ku-30 imizuzwana. Yenza kabusha i-codec eyahlukileyo: 10 kuya ku-20% yesikhathi somthombo, ngakho-ke ihora M4A → AAC liphela ngemizuzu engu-6 kuya ku-12. Imisebenzi yeqembu ihamba ngokufanayo phakathi kwabasebenzayo ukuze kube nokukhawulela okuningi.

Kungani i-AAC izwakala kakhulu noma ihlala incane kunaleli cebo i-M4A?

Akukho shintsho lokufinyelela oluzenzakalelayo kwenziwa ngaphandle kokuthi uvule isinqumo sokujwayelekile. Uma ubona ushintsho lwezinga, umdlali wakho womsindo noma ithala lemithombo lizosebenzisa i-ReplayGain noma ukuguqulwa kwezinga ngalinye lomdlalo — hhayi nathi. Ungasebenzisi lokhu ukulalela ama-AAC ajwayelekile.

Ingabe ngiguqula M4A ukulayisha phezulu kusuka kuzinsizakalo zokusakaza ku AAC?

Uma i-M4A ilayishwe phansi ingakhuselwanga (akukho DRM), yebo. Ama-streams abhalwe nge-DRM (ama-Spotify, ama-Apple Music tracks) abhalwe nge-crypto ku-bit level futhi asikwazi ukuwaphatha. Ama-Bandcamp, ama-SoundCloud alayishwe phansi, ukurekhodwa komuntu siqu, nama-podcast amafayela aguqulwa ngokucophelela.

M4A

I-M4A ifomethi yefayela lomsindo ehlobene eduze ne-MP4. Inikeza ukucindezelwa komsindo kwekhwalithi ephezulu ngokusekelwa kwemethadatha, okuyenza ifanelekele izinhlelo zokusebenza ezihlukahlukene.
