WMA kuya AMR Imibuzo Evame Ukubuzwa Yokuguqulwa

Ngiguqula kanjani umsindo WMA ube AMR ngaphandle kokulahlekelwa ukhwalithi?

Layisha phezulu ihele WMA 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-WMA ilahlekelwa yiphutha, ebhokisini le-ASF, nge-lossless nezwi elingcono kakhulu elivame ukutholakala. 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 ukushintsha WMA kuya ku AMR kuyingxenye yesithathu yokucindezela okulahlekile?

Yebo, futhi kufanelekile ukuhlela. Izifomethi zombili ziyi-lossy, ngakho-ke i-AMR 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-AMR kusuka kulo kunciphisa ukudlula okuphindiwe ngokuphelele.

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

Akulungile. WMA 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-WMA 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 WMA 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 ezinye ze WMA zefayela lami zingaguqulwa?

DRM. Iqoqo elincane lamafayela WMA libhalwe ngokufihlakele yisitolo noma isofthiwe eyenza, futhi umsindo obhalwe ngokufihlakele awukwazi ukukhishwa yinoma iyiphi i-convertor. Noma yini oyidingayo, orekhodiwe, noma othengiswe ngaphandle kokuvikelwa uguqulwa ngokuvamile; ukuthengiswa kwelayisense akuzokwenza. 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.

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 WMA kuya ku AMR kuzonciphisa ubunjani bomsindo wami?

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

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

Yebo — isihloko, umculi, i-album, unyaka, inani lesiqalo, nesithombe se-album zifundwa kusuka ku WMA 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-WMA abe AMR?

Yebo — susa isibaya se WMA 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-WMA?

Ngephutha yebo — 48 kHz WMA 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 WMA 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.

WMA

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

AMR

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