Indlela yokuguqula MP3 kuya AMR

Isinyathelo 1: Layisha eyakho MP3 amafayela usebenzisa inkinobho engenhla noma ngokuhudula bese uphonsa.

Isinyathelo 2: Chofoza inkinobho ethi 'Guqula' ukuze uqale ukuguqulwa.

Isinyathelo 3: Landa i-version yakho AMR amafayela

MP3 kuya AMR Imibuzo Evame Ukubuzwa Yokuguqulwa

Ngiguqula kanjani umsindo MP3 ube AMR ngaphandle kokulahlekelwa ukhwalithi?

Layisha phezulu ihele MP3 futhi umguquli wethu uzokhetha i AMR codec / bitrate ukuhlanganisa okuhambisana nomsuka. Inhloso engalahleki (AMR = WAV / FLAC / ALAC) igcina yonke isampula; inhloso elahlekile (AMR = MP3 / AAC / OGG / Opus) iphutha liyi 192 kbps ecacile kumazwana amaningi.

Ihele AMR lisebenzisa i-bitrate enjani?

Iphutha 192 kbps ku AMR olahlekelwayo; dlula-ngaphaya (akukho sinqumo se-bitrate) ku AMR okungabi nalutho. Nciphisa ku 320 kbps ku-audiophile output, noma 96 kbps ku-voice / podcast lapho amafayela amancane abalulekile kuneqiniso ezindaweni eziphezulu.

Ingabe ukusuka ku MP3 kuya ku AMR kuzonciphisa ubunjani bomsindo wami?

Uma MP3 ilahlekelwa futhi AMR ayilahleki (isibonelo MP3 -> WAV), ihele AMR alingcono kuna MP3 — awukwazi ukubuyisela imininingwane edlulele. Uma MP3 ilahlekelwa futhi AMR ayilahleki, i-AMR codec icindezela futhi; ku-192 kbps lokhu kucacile kuningi kwezithameli.

Ingabe i-MP3 kuya ku-AMR igcina amathegi we-ID3 / metadata?

Yebo — isihloko, umculi, i-album, unyaka, inani le-track, kanye ne-album efakwe isithombe zifundwa kusuka ku MP3 futhi zibhalwe ngaphakathi kwe AMR ibhokisi lapho i-AMR ifaka khona izixhumanisi (ezizokwenziwa yizo zonke ezijwayelekile).

Ingabe ngingenza i-batch yokuguqula amahele angama-MP3 abe AMR?

Yebo — susa isibaya se MP3 amafayela ngaphakathi futhi sizoziphatha ngokufanayo. I-Pro 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-AMR izogcina isilinganiso esifanayo sesampula njenge-MP3?

Ngokuzenzakalela yebo (48 kHz MP3 -> 48 kHz AMR). Uma ufuna ukusatshalaliswa okuphansi kokuhambisana (isibonelo 96 kHz -> 44.1 kHz yokushaya i-CD) isinqumo esiphezulu sesampula-rate siphatha lokhu ngesampula esezingeni eliphakeme le-polyphase.

Ingabe ngizolungisa umsindo ku-MP3 kuya ku-AMR?

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

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

MP3 idlala jikelele. AAC idlala ku Apple, Android abaningi, kanye Sonos. FLAC idlala ku Sonos kanye Android yamanje, ngaphezu kahle ku iPods edlule. WAV idlala konke kodwa kukhulu. Izinketho eziphezulu zifaka idivayisi presets lezi izinhloso ezivamile.

Ingabe ihele lami MP3 liyimfihlo ngesikhathi sokuguqulwa?

Yebo — amafayela alayishwe phezulu MP3 aqhubekelwa phambili emisebenzini ehlukanisiwe futhi acishwe ngaphakathi kwemizuzu. Asikwazi ukudlala, ukugcina, noma ukuhlanganisa okuqukethwe kwesandi. Bona /privacy/ ngefasitela lokugcinwa kwedatha.

Ingabe kuthatha isikhathi esingakanani ukushintsha ihora le-MP3 libe AMR?

I-codec efanayo iphinde i-mux: imizuzwana engu-10-30. Yenza kabusha i-codec ehlukile: ngokuvamile 10-20% yesikhathi somthombo, ngakho-ke ihora MP3 -> AMR liphele ngemizuzu engu-6-12 kwipayipi elijwayelekile.

Kungani ihele AMR likhulu / lihlanzekile kunalelo MP3?

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

Ingabe ngiguqula ama-MP3 alayishwe phansi abe AMR?

Uma i-MP3 ilayishwe phansi ingakhuselwanga (akukho DRM), yebo. Amafayela we-streaming abhalwe nge-DRM (i-Spotify, i-Apple Music) abhalwe nge-crypto ku-bit level futhi asikwazi ukuwaphatha. Ama-sources e-Bandcamp, SoundCloud, nama-recordings asekhaya aguqulwa kahle.

MP3

Amafayela e-MP3 asebenzisa ukucindezela okulahlekile ukunciphisa usayizi wefayela ngenkathi kugcinwa ikhwalithi yomsindo eyamukelekayo kubalaleli abaningi.
