AMR kuya WMA Imibuzo Evame Ukubuzwa Yokuguqulwa

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

Layisha phezulu ihele AMR futhi umguquli ukhetha i WMA codec ne-bitrate ukufana nomsuka. Ukungabi nalutho WMA (WAV / FLAC / ALAC) ugcina yonke isampula nge-bit-identical; ukungabi nalutho WMA (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-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, ukukopisha i-WMA kusuka kulo kunciphisa ukudluliswa 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 kokungena ngesandla. I-WMA icindezelwe kahle kunalezi MP3 eziqokomisa 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 eziphambili nezidlali abadala; WMA idinga isofthiwe eyazi i-codec, esebenzisa ihardware ehlukile. 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 angathwala 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 ezoba yihele elitholakele WMA lisebenzisa?

Iphutha lingu-192 kbps ku-lossy WMA; dlula-nge-lossless WMA. 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 WMA kuzonciphisa ukhwalithi yomsindo wami?

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

Ingabe i-AMR kuya ku-WMA 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 WMA ibhokisi lapho ifomu lixhasa iziphawuli. Zonke izinhloso ezijwayelekile (MP3, AAC, FLAC, OGG) ziphatha iziphawuli kahle; i-WAV emnyama ayisebenzi. WMA Windows Media Audio, Microsoft's impendulo MP3, yaqala ngo-1999 futhi bundled ngazo zonke Windows kufaka lesikhathi.

Ingabe ngingakwazi ukushintsha amahele amakhulu AMR ku WMA?

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-WMA izogcina isilinganiso esifanayo sesampula njenge-AMR?

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

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

Ingabe WMA 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-WMA codec elungele i-hardware yakho efanele.
