FLAC kuya AMR Imibuzo Evame Ukubuzwa Yokuguqulwa

Ngiguqula kanjani umsindo FLAC ube AMR ngaphandle kokulahlekelwa ukhwalithi?

Layisha phezulu ihele FLAC futhi umguquli ukhetha i-AMR codec ne-bitrate ukufana nomsuka. Ukungabi naphutha AMR (WAV / FLAC / ALAC) ugcina yonke isampula nge-bit-identical; ukungabi nalutho AMR (MP3 / AAC / OGG / Opus) kumiswa ku-192 kbps okucacile kuma-earphones amaningi. I-FLAC isebenzisa ukubikezela okuqondile kanye nokuhlelwa kwe-Rice ukufinyelela cishe ku-50-60% wesayizi yangempela ngesikhathi sokuhlelwa emuva kwe-PCM efana ne-bit. 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.

Ingabe ngilahlekelwa yikhwalithi eningi uma ngiguqula FLAC kuya ku AMR?

Ezinye, futhi zihlala - lokhu kuyindlela eyodwa lapho ulwazi luthunyelwe khona. FLAC ligcina yonke imibiko ngokugcwele; AMR lisusa lokho imodeli ye-psychoacoustic icabanga ukuthi awukwazi ukulalela. Ku-192 kbps futhi ngaphezu kwalokho, i-prediction iyilungile ngokwanele ukubukeka kahle kuningi kwamathuluzi nangaphezulu kwamathuluzi. Gcina i-FLAC njenge-master yakho, ngoba awukwazi ukubuyela kuyo kusuka ku-AMR.

Ingabe izihloko zengoma yami nesithombe se-albhamu sizohlala isikhathi eside uma ngishintsha FLAC kuya ku AMR?

Akulungile. FLAC ifaka i-metadata efanele, kodwa AMR ayinaso isikhala esijwayelekile somuntu oculi, i-album, inani le-track noma umhlobiso we-cover, ngakho-ke amathegi asuswa ngaphandle kokulahleka. Gcina i-FLAC njengekhophi elabelwe, noma uphinde ubeke i-tag ngemuva ngethuluzi njenge Mp3tag noma MusicBrainz Picard. I-AMR ibulala umculo: i-8 kHz bandwidth yayo isusa konke okuphezulu kwe-frequency yefoni, futhi akukho inani lokuphindeka kokucofa liyibuyisela emuva.

Yini ekwenzeke kumsindo othile uma uguqula FLAC ku AMR?

Ihlolwe phansi ku-stereo, ngoba AMR ayinayo indlela esebenzayo ye-multichannel. Ukuxuba okuphansi kusetshenziswa izilinganiso ezijwayelekile ukuze umhlangano we-channel ephakathi uhlale ucacile futhi izingqimba zixhunywe ku-level ephansi. Noma yini esekelwe ekubekeni kwe-channel ehlukile idlule lapho lokhu kwenzeke.

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. FLAC akazange ashintshe, futhi Apple's ecosystem kuphela engeza insizakalo okwamanje futhi grudgingly.

Yini i-bitrate ongayisebenzisa ihele elivela ku-AMR?

Iphutha ngu-192 kbps ku AMR olahlekelwayo; ukudluliswa-kwe- AMR 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 FLAC kuya ku AMR kuzonciphisa ubunjani bomsindo wami?

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

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

Yebo — isihloko, umculi, i-album, unyaka, inani lesiqalo, nesithombe se-album zifundwa kusuka ku FLAC isitoreji futhi zibhalwe ku AMR isitoreji lapho ifomu lixhasa amathegi. Zonke izimo ezijwayelekile (MP3, AAC, FLAC, OGG) ziphatha amathegi kahle; i-WAV engaqondakali ayisebenzi. I-AMR iyi-Adaptive Multi-Rate, i-codec yokukhuluma i-3GPP ejwayelekile yezingcingo zokukhuluma ze-GSM nezinhlelo zokurekhoda amagama ezimoto.

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

Yebo — susa isibaya se FLAC 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-FLAC?

Ngephutha yebo — 48 kHz FLAC ihlala 48 kHz ku AMR. 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 FLAC ku AMR?

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

Ingabe AMR 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-AMR codec elungele i-hardware yakho efanele. I-AMR yenza ukurekhodwa kwezwi kube ncane kakhulu - ihora lokuxoxa lifaka ama-megabytes ambalwa - futhi yilokho okunye amafoni amaningi aqhubeka nokurekhoda ukufona.

FLAC

I-FLAC inikeza ukucindezelwa komsindo okungenakulahlekelwa, kunciphisa usayizi wefayela ngenkathi kulondolozwa ikhwalithi yomsindo yokuqala engu-100%.

AMR

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