Indlela yokuguqula AMR kuya M4A

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

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

Inyathelo 3: Qapha okuguqulwe M4A amafayela

AMR kuya M4A Imibuzo Evame Ukubuzwa Yokuguqulwa

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

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

Yini i-bitrate i-M4A isebenzisayo?

Iphutha 192 kbps ku-lossy M4A; idlula-nge-lossless M4A. 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-AMR kuya ku-M4A kuzonciphisa izinga lami lomsindo?

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

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

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

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

Yebo — khipha isibaya se-AMR 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-AMR?

Ngokuzenzakalela yebo (48 kHz AMR → 48 kHz M4A). 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-AMR kuya ku-M4A?

Yebo — ukhetho lokujwayelekile-lokujwayelekile lufaka ITU-R BS.1770 / EBU R128 ukujwayelekile ku-M4A output, lubeka inhloso -14 LUFS (isilinganiso sokusakaza) noma -16 LUFS (isilinganiso sepodcast). Kuhle uma uguqula amabhayisikobho ngezinga lokuphatha elihlukile.

Ingabe i-M4A 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 AMR liyimfihlo ngesikhathi sokuguqulwa?

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

Ithatha isikhathi esingakanani ukushintsha AMR yehora elilodwa kuya kuM4A?

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

Kungani ihele M4A likhulu / lihlanzekile kunalelo AMR?

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 AMR ukulayisha phezulu kwe-streaming ku-M4A?

Uma AMR 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.
