AMR kuya WMA Imibuzo Evame Ukubuzwa Yokuguqulwa

Ngiguqula kanjani umsindo AMR ube WMA ngaphandle kokulahlekelwa ukhwalithi?

Layisha phezulu ihele AMR futhi umguquli ukhetha i-WMA codec ne-bitrate ukufana nomsuka. Ukungabi naphutha WMA (WAV / FLAC / ALAC) ugcina yonke isampula nge-bit-identical; ukungabi nalutho WMA (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-WMA ilahlekelwa yiphutha, ebhokisini le-ASF, nge-lossless nezwi elingcono kakhulu elivame ukutholakala.

Ingabe ukushintsha AMR kuya ku WMA kuyingxenye yesithathu yokucindezela okulahlekile?

Yebo, futhi kufanelekile ukuhlela. Izifomethi zombili ziyi-lossy, ngakho-ke i-WMA encoder isebenza kusuka kumsindo osele udlulele engxenyeni eyodwa ye-psychoacoustic, futhi iziphakamiso zayo zihlanganisa isiqephu sokuqala. Ku-192 kbps noma ngaphezulu, imiphumela ihlala icacile kakhulu. Uma une-lossless master nganoma yikuphi, uku-encoding i-WMA kusuka kulo kunciphisa ukudlula okuphindiwe ngokuphelele.

Ingabe ngiyiphawula i WMA ngemininingwane yomuntu odlalayo ne-album?

Yebo, futhi kuyinzuzo engokoqobo ngaphezulu kwe AMR, engeke ikwazi ukugcinwa kuphi naphi. WMA 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. I-WMA icindezelwe kahle kunalokho okusho ama-MP3 encoders amanje futhi ihlala ifundeka yi-Windows Media Player nezinhlelo zakudala ze-PlaysForSure.

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

Ngokuvamile akunjalo. AMR i-decoded yinoma yini, kufaka phakathi izimoto eziphezulu nezidlali ezikhulu; WMA 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. WMA ayixhaswanga cishe kuwo wonke indawo ngaphandle Windows, futhi WMA older amafayela angaba nesi DRM ukuthi ivala ukuguqulwa ngokuphelele.

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. I-AMR ibulala umculo: i-8 kHz bandwidth yayo isusa konke okuphezulu kwe-frequency yefoni, futhi akukho inani lokuphindeka kokucofa liyibuyisela emuva.

Yini i-bitrate ongayisebenzisa ihele elivela ku-WMA?

Iphutha ngu-192 kbps ku WMA olahlekelwayo; ukudluliswa-kwe- WMA 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 WMA kuzonciphisa ubunjani bomsindo wami?

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

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

Yebo — isihloko, umculi, i-album, unyaka, inani lesiqalo, nesithombe se-album zifundwa kusuka ku AMR isitoreji futhi zibhalwe ku WMA isitoreji lapho ifomu lixhasa amathegi. Zonke izimo ezijwayelekile (MP3, AAC, FLAC, OGG) ziphatha amathegi kahle; i-WAV engaqondakali ayisebenzi. WMA Windows Media Audio, Microsoft's impendulo MP3, yaqala ngo-1999 futhi bundled ngazo zonke Windows ukufaka lesikhathi.

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

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-WMA izogcina isilinganiso esifanayo sesampula njenge-AMR?

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

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

Ingabe WMA 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-WMA 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.

WMA

I-WMA (i-Windows Media Audio) ifomethi yokucindezela umsindo eyakhiwe yi-Microsoft. Ivamise ukusetshenziselwa ukusakaza kanye namasevisi omculo aku-inthanethi.
