AIFF kuya AAC Imibuzo Evame Ukubuzwa Yokuguqulwa

Ngiguqula kanjani umsindo AIFF ube AAC ngaphandle kokulahlekelwa ukhwalithi?

Layisha phezulu ihele AIFF futhi umguquli wethu uzokhetha i AAC codec / i-bitrate ehambisanayo necebo. Injongo engalahleki (AAC = WAV / FLAC / ALAC) igcina yonke isampula; injongo elahlekile (AAC = MP3 / AAC / OGG) iphutha liyi-192 kbps ecacile yencwadi yezwi elikhulumayo kanye neminye imiculo.

Ingabe ngilahlekelwa yikhwalithi eningi uma ngiguqula AIFF kuya ku AAC?

Ezinye, futhi zihlala - lokhu kuyindlela eyodwa lapho ulwazi luthunyelwe khona. AIFF ligcina yonke imibiko ngokugcwele; AAC lisusa lokho imodeli ye-psychoacoustic icabanga ukuthi awukwazi ukulalela. Ku-192 kbps futhi ngaphezu kwalokho, i-prediction iyilungile ngokwanele ukubukeka kahle kuningi kwamathuluzi nemishini. Gcina i-AIFF njenge-master yakho, ngoba awukwazi ukubuyela kuyo kusuka ku-AAC. I-AIFF igcina i-PCM engacindezelwanga enkulu-enddian — i-Apple-side elinganayo ne-WAV, nge-bit-for-bit fidelity efanayo. I-AAC ilahlekelwa yinto kodwa isebenza kahle kunayo i-MP3, futhi iphatha kuze kube yi-48 channels ngokusemthethweni ngaphezu kokuboshwa ku-stereo design.

Ihele AAC lisebenzisa i-bitrate enjani?

Iphutha ngu-192 kbps ku AAC olahlekelwayo; udlulisa-nge- AAC ongenalutho. Nciphisa ku-320 kbps ku-audiophile noma ku-64-96 kbps ku-audiobooks ekhuluma-magama (icacile ku-voice, ihlukanise ubukhulu befayela ngamaphesenti).

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

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

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

Yebo — isihloko, umculi, i-album, unyaka, inani le-track, i-album art, nama-chapter markers (abalulekile kuma-audiobooks) afundwa kusuka ku-AIFF futhi abhalwe ku-AAC ibhokisi lapho i-AAC ifomu lixhasa amathegi. Ukwakhiwa kwe-audiobook M4B kuhamba-hamba ku-M4B ne-AAX → M4B output.

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

Yebo — susa isibaya se AIFF 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-AIFF?

Ngokuzenzakalela yebo (48 kHz AIFF → 48 kHz AAC). 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-AIFF kuya ku-AAC?

Yebo — ukhetho lokujwayelekile-lokujwayelekile lufaka ITU-R BS.1770 / EBU R128 ukujwayelekile ku AAC kuphuma, libhekisa ku -14 LUFS (isizinda sokushayela), -16 LUFS (isizinda sepodcast), noma -23 LUFS (isizinda sencwadi yezwi). Kuhle uma uguqula amabhayisikobho ngezinga lokuphatha elihlukile.

Ingabe i-AAC izodlala kwi-stereo yemoto yami / i-iPod / i-app yencwadi yezwi?

MP3 idlala emhlabeni wonke. AAC idlala ku Apple, ngaphezu Android, Sonos. FLAC idlala ku Sonos ne Android, ngaphezu kahle ku iPods edlule. M4B audiobooks dlala ngesigaba ukuzulazula ku iOS Books, Audiobookshelf, kanye Smart Audiobook Player. Izinto ezikhethwayo ezisezingeni eliphezulu zifaka idivayisi imise.

Ingabe ihele lami AIFF liyimfihlo ngesikhathi sokuguqulwa?

Yebo — amafayela alayishwe phezulu AIFF aqhubekelwa phambili abasebenza ngokuzimela futhi acishwe ngaphakathi kwemizuzu. Asikwazi ukudlala, ukugcina, noma ukuhlanganisa okuqukethwe kwesandi. Kubalulekile kakhulu uma usebenza nama-library wencwadi yesandi.

Ingabe kuthatha isikhathi esingakanani ukushintsha i-audiobook yehora elilodwa AIFF iye ku-AAC?

I-codec efanayo iphinde i-mux: 10-30 imizuzwana. Yenza kabusha i-codec eyahlukileyo: 10-20% yesikhathi somthombo, ngakho i-audiobook yehora elilodwa liphele ngemizuzu engu-60-120. Ama-chapter markers ahlala ehamba futhi ahlukaniswe ngokuhlanzekile.

Kungani ihele AAC likhulu / lihlanzekile kunalelo AIFF?

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.
