Indlela yokuguqula AAC kuya AMR

Isinyathelo 1: Layisha eyakho AAC 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

AAC kuya AMR Ukushintsha

Ngiguqula kanjani umsindo AAC ube AMR ngaphandle kokulahlekelwa ukhwalithi?

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

Ihele AMR lisebenzisa i-bitrate enjani?

Iphutha 192 kbps ku AMR olahlekelwayo; dlula-nge- AMR ongalahlekelwanga. Nciphisa ku 320 kbps ku-audiophile noma ku 96 kbps ku-voice / podcast. Ukhetho lushintsha ubukhulu behele ku fidelity ezwakalayo ku bitrates ephansi kakhulu.

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

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

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

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

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

Yebo — susa isibaya se AAC 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-AMR izogcina isilinganiso esifanayo sesampula njenge-AAC?

Ngokuzenzakalela yebo (48 kHz AAC → 48 kHz AMR). Uma ufuna uku-downsample ukuhambisana (isibonelo 96 kHz → 44.1 kHz yokushaya i-CD) isinqumo esiphezulu sesampula-rate sikwenza lokhu ngekhwalithi ephezulu yoku-resamply.

Ingabe ngizolungisa umsindo ku-AAC 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 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 AAC liyimfihlo ngesikhathi sokuguqulwa?

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

Ingabe kuthatha isikhathi esingakanani ukushintsha ihora le-AAC 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 AAC → AMR liphele ngemizuzu engu-6-12.

Kungani ihele AMR likhulu / lihlanzekile kunalelo AAC?

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 AAC ukulayisha phezulu okuqhubekayo ku AMR?

Uma i-AAC ilayishwe phansi ingakhuselwanga (akukho DRM), yebo. Amafayela okuhamba ngokufihliwe nge-DRM (i-Spotify, i-Apple Music) alayishwe phansi ku-bit level futhi asikwazi ukuwaphatha. Ama-sources e-Bandcamp, i-SoundCloud alayishwe phansi, nama-recordings angaphakathi aguqulwa kahle.
