AMR kuya AIFF Imibuzo Evame Ukubuzwa Yokuguqulwa

Ngiyiguqula kanjani i-AMR yomsindo ibe yi-AIFF ngaphandle kokulahlekelwa ukhwalithi?

Layisha phezulu ihele AMR futhi umguquli ukhetha i AIFF codec ne-bitrate ukufana nomsuka. Ukungabi nalutho AIFF (WAV / FLAC / ALAC) ugcina yonke isampula nge-bit-identical; ukungabi nalutho AIFF (MP3 / AAC / OGG / Opus) iphutha ku-192 kbps ecacile kulezi zindlebe eziningi. I-AMR iyi-narrowband speech codec esebenza phakathi kuka-4.75 no-12.2 kbps, emodela i-human vocal tract ngaphezu kwe-audio spectrum ephelele. I-AIFF igcina i-PCM engacindezelwanga enkulu-enddian — i-Apple-side elinganayo ne-WAV, nge-bit-for-bit fidelity efanayo.

Ingabe ukushintsha AMR kuya ku AIFF kuzothuthukisa ukhwalithi yomsindo?

Akunalutho, futhi kufanelekile ukuba kucace: akukho okuzokwenzeka. I AMR idlulele i-detail ngesikhathi sokuqothula kwayo okujwayelekile, futhi ukubopha okushiwo ku AIFF ongeke ulahlekelwa yilutho kugcina lokho - akukho okuningi. Ihele lithola izikhathi eziningi ezikhulu futhi lizwakala lifana. Kukhona ukunyakaza okulungile ngaphambi kokuhlela, ngoba AIFF ngeke ihlanganise isizukulwane sesithathu sezinto ezibonakalayo uma ukhipha. I-AIFF iyifomethi yokushintshana kwestudio ku-macOS, iphatha i-metadata kahle kunayo i-WAV ejwayelekile, futhi ingenisa ku-Logic ne-Pro Tools ngokushesha. I-AMR ibulala umculo: i-8 kHz bandwidth yayo isusa konke okuphezulu kwe-frequency yefoni, futhi akukho inani lokuphindeka kokucofa liyibuyisela emuva.

Ingabe ngiyiphawula i AIFF ngemininingwane yomuntu odlalayo ne-album?

Yebo, futhi kuyinzuzo engokoqobo ngaphezulu kwe AMR, engeke ikwazi ukugcinwa kuphi naphi. AIFF ifaka isihloko, umculi, i-album, unyaka, inani le-track kanye ne-cover art efakwe ngaphakathi kwebhokisi, ngakho-ke i-library yomculo ifaka ngokulungile ngaphandle kokungena ngesandla.

Ingabe i-AIFF izodlala emoto yami noma ku-hardware edala?

Ngokuvamile akunjalo. AMR i-decoded yinoma yini, kufaka phakathi izimoto eziphambili nezidlali abadala; AIFF idinga isofthiwe eyazi i-codec, esebenzisa ihardware ehlukile. Uma indawo esiya kuyo imoto ye-stereo noma umdlali ophathekayo, lokhu kuyisinqumo esiqinile sokuhlala ku AMR. I-AIFF ikhulu njenge-WAV futhi inezixhaso ezibi ngaphandle kwe-Apple world, ngakho-ke iyisinqumo esibi sokusakaza.

Kungani umculo uzwakala ubuhlungu kulo mguquko?

Ngenxa yokuthi ingxenye eyodwa iyi-codec yokuxoxa hhayi i-codec yomculo. Imodelisa i-human vocal tract futhi isusa konke okungaphandle kwe-bandwidth yefoni, okulungile ku-voice memo futhi kulahlekile kunoma yini enezithuluzi ngaphakathi. Ukushintshana eduze kwayo akukwazi ukubuyisela izifremu ezilahlekile — azikhombisile endaweni yokuqala.

Yini i-bitrate ezoba yihele elitholakele AIFF lisebenzisa?

Iphutha lingu-192 kbps ku-lossy AIFF; dlula-nge-lossless AIFF. Yisuse ku-320 kbps ku-audiophile noma ku-96 kbps ku-voice / podcast. Ukhetho lushintsha ubukhulu behele ku-audible fidelity; ngaphansi kwe-96 kbps i-lossy artifacts ibonakale kumculo.

Ingabe ukudlula kusuka ku AMR kuya ku AIFF kuzonciphisa ukhwalithi yomsindo wami?

Uma AMR ilahlekelwa yinto futhi AIFF ayilahlekelwanga (isibonelo MP3 → WAV), AIFF ayingcono kuna AMR — awukwazi ukubuyisela imininingwane elahlekile. Uma AMR ilahlekelwa yinto futhi AIFF ayilahlekelwanga, AIFF i-codec icindezela kabusha; ku-192 kbps imiphumela icacile kuningi kwezithameli.

Ingabe i-AMR kuya ku-AIFF iguqula igcina ID3 / metadata tags?

Yebo — isisihloko, umculi, i-album, unyaka, inani le-track, kanye ne-album art zifundwa kusuka ku AMR ibhokisi futhi zibhalwe ku AIFF ibhokisi lapho ifomu lixhasa iziphawuli. Zonke izinhloso ezijwayelekile (MP3, AAC, FLAC, OGG) ziphatha iziphawuli kahle; i-WAV emnyama ayisebenzi. AIFF Apple's Audio Interchange File Format kusukela 1988, eyenziwe nge IFF efanayo chunk design njenge AVI RIFF.

Ingabe ngingakwazi ukushintsha amahele amakhulu AMR ku AIFF?

Yebo - khipha isibaya se AMR amafayela ngaphakathi futhi sizoziphatha ngokuhambisana. I-Premium inemisebenzi eminingi ehambisanayo futhi akukho lutho oluphezulu lwesayizi yefayela ngalinye, ngakho-ke i-500-file batch iqedela imizuzu endaweni yamahora angama-10.

Ingabe i-AIFF izogcina isilinganiso esifanayo sesampula njenge-AMR?

Ngokungajwayelekile yebo — 48 kHz AMR ihlala 48 kHz ku AIFF. Uma ufuna ukusatshalaliswa ngezansi ukuze kusebenze (96 kHz → 44.1 kHz ukuthwebula i-CD), isampula-rate option ifaka ukusatshalaliswa okusezingeni eliphezulu kulowo mkhawulo wokucofoza.

Ingabe ngikwazi ukushintsha umsindo uma ngiguqula AMR kuya ku AIFF?

Yebo — i-loudness-normalize option ifaka i-ITU-R BS.1770 / EBU R128 normalization ku-AIFF, idinga -14 LUFS (isilinganiso sokusakaza) noma -16 LUFS (isilinganiso sepodcast). Kuhle uma uhlela ama-tracks amastered kuma-levels ahlukene.

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

MP3 idlala kuwo wonke amathuluzi. AAC idlala ku-Apple, ku-Android, ne-Sonos. FLAC idlala ku-Sonos ne-Android kodwa hhayi ku-iPods ezidala. WAV idlala kuwo wonke amathuluzi kodwa ikhulu. Idivayisi ethuthukisiwe-isethelwe ngaphambili ikhetha i-AIFF codec elungele i-hardware yakho efanele.
