AMR kuya AIFF Imibuzo Evame Ukubuzwa Yokuguqulwa

Ngiguqula kanjani umsindo AMR ube AIFF ngaphandle kokulahlekelwa ukhwalithi?

Layisha phezulu ihele AMR futhi umguquli ukhetha i-AIFF codec ne-bitrate ukufana nomsuka. Ukungabi naphutha AIFF (WAV / FLAC / ALAC) ugcina yonke isampula nge-bit-identical; ukungabi nalutho AIFF (MP3 / AAC / OGG / Opus) kumiswa ku-192 kbps okucacile kuma-earphones amaningi. I-AMR iyi-narrowband speech codec esebenza phakathi kuka-4.75 no-12.2 kbps, emodela i-human vocal tract endaweni yobubanzi obugcwele be-audio spectrum. I-AIFF igcina i-PCM engacindezelwanga enkulu-endian — 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 kunaleyo ye-WAV, 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 kokufaka isandla.

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

Ngokuvamile akunjalo. AMR i-decoded yinoma yini, kufaka phakathi izimoto eziphezulu nezidlali ezikhulu; AIFF idinga isofthiwe eyazi i-codec, esizohlala i-hardware ehlala ikhona. 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 ongayisebenzisa ihele elivela ku-AIFF?

Iphutha ngu-192 kbps ku AIFF olahlekelwayo; ukudluliswa-kwe- AIFF okungalahleki. Nciphisa ku-320 kbps ku-audiophile noma ku-96 kbps ku-voice / podcast. Ukhetho lushintsha ubukhulu behele ku-audible fidelity; ngaphansi kuka-96 kbps olahlekelwayo, ama-artefacts abonakala emculo.

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

Uma AMR ilahlekelwa futhi AIFF ayilahleki (isibonelo MP3 → WAV), AIFF ayingcono kuna AMR — awukwazi ukubuyisela imininingwane elahlekile. Uma AMR ilahlekelwa futhi AIFF ayilahleki, i-AIFF codec icindezela futhi; ku-192 kbps imiphumela icacile kunoma iyiphi ingxenye.

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

Yebo — isihloko, umculi, i-album, unyaka, inani lesiqalo, nesithombe se-album zifundwa kusuka ku AMR isitoreji futhi zibhalwe ku AIFF isitoreji lapho ifomu lixhasa amathegi. Zonke izimo ezijwayelekile (MP3, AAC, FLAC, OGG) ziphatha amathegi kahle; i-WAV engaqondakali ayisebenzi. AIFF Apple's Audio Interchange File Format kusukela 1988, eyenziwe nge IFF efanayo chunk design njenge AVI RIFF.

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

Yebo — susa 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-AIFF izogcina isilinganiso esifanayo sesampula njenge-AMR?

Ngephutha yebo — 48 kHz AMR ihlala 48 kHz ku AIFF. Uma ufuna ukusatshalaliswa ngezansi ukuze kusebenze (96 kHz → 44.1 kHz ukushaya i-CD), isinqumo sesampula-sayizi sifaka ukusatshalaliswa okusezingeni eliphezulu kuleyo ngxenye yokungenisa ikhodi.

Ingabe ngizolungisa umsindo uma ngiguqula AMR ku AIFF?

Yebo — ukhetho lokujwayelekile-lokujwayelekile lufaka ITU-R BS.1770 / EBU R128 ukujwayelekile ku AIFF, lubeka inhloso -14 LUFS (isizinda sokushayela) noma -16 LUFS (isizinda sepodcast). Kuhle uma kuhlanganiswa amabhayisikobho aqeqeshiwe ezingeni ezahlukene.

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

MP3 idlala kuwo wonke amadivayisi. I-AAC idlala ku-Apple, ku-Android, ne-Sonos. I-FLAC idlala ku-Sonos ne-Android kodwa ayikho ku-iPods edlule. I-WAV idlala kuwo wonke amadivayisi kodwa inamandla amakhulu. Imenyu yokudonsa yedivayisi ethuthukisiwe ikhetha i-AIFF codec elungele i-hardware yakho efanele.

AMR

I-AMR (I-Adaptive Multi-Rate) ifomethi yokuminyanisa yomsindo elungiselelwe ukubhalwa kwekhodi yenkulumo. Ivamise ukusetshenziswa kumakhalekhukhwini ukuqoshwa kwezwi nokudlalwa komsindo.

AIFF

I-AIFF (i-Audio Interchange File Format) ifomethi yefayela lomsindo engacindezelwanga evame ukusetshenziswa ekukhiqizweni komsindo nomculo okuphrofeshinali.
