AMR kuya WMA Imibuzo Evame Ukubuzwa Yokuguqulwa

Ngiguqula kanjani umsindo AMR ube WMA ngaphandle kokulahlekelwa ukhwalithi?

Layisha phezulu ihele AMR futhi umguquli ukhetha WMA i-codec / i-bitrate ehambisana neprofayili yomsuka. I-lossless WMA (WAV / FLAC / ALAC) igcina yonke isampula ngokugcwele; i-lossy WMA (MP3 / AAC / OGG / Opus) iphutha liyi-192 kbps ecacile kakhulu kunoma iyiphi ingxenye yomculo. 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.

Ihele WMA liphele nini nge-bitrate?

Iphutha 192 kbps ku WMA olahlekelwayo; dlula-nge- WMA ongalahlekelwayo. Nciphisa ku 320 kbps uma ufuna ubukhulu obuphezulu bokungathembeki okulahlekile, 128 kbps ku-podcast yokusabalalisa obukhulu-bulinganiselwe, noma 96 kbps ku-voice-only sources lapho ifayela elincane libalulekile kunemininingwane yestudio.

Ingabe ukusuka ku AMR kuya ku WMA kuzonciphisa kakhulu izinga lami lomsindo?

Uma AMR ilahlekelwa (MP3, AAC) futhi WMA ayilahlekelwanga (WAV, FLAC), WMA ayingcono kuna AMR — awukwazi ukubuyisela imininingwane elahlekile yi-AMR codec elahlekile. Uma AMR ayilahlekelwanga futhi WMA ilahlekelwa, cabanga ukuthi i-WMA encoder izocindezela futhi; ku-192 kbps ilahlekelwa ayikwazi ukubonwa yimilomo eminingi.

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

Yebo — isihloko, umculi, i-album, unyaka, inani le-track, i-album art, BPM, ukuphindeka-kwe-gain kufundeka kusuka ku AMR ibhokisi futhi kubhalwe kuma-fields alinganayo ku WMA ibhokisi. ID3v2 (MP3), amazwana we-Vorbis (OGG, FLAC), ama-MP4 atoms (AAC, M4A), RIFF INFO (WAV), ama-iXML chunks wonke ama-maps ngokuhlanzekile. WMA Windows Media Audio, Microsoft's impendulo MP3, yaqala ngo-1999 futhi bundled ngazo zonke Windows ukufaka lesikhathi.

Ingabe ngingenza ukuguqulwa kwekhulu le AMR amafayela 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 amahlanu. Ukwakhiwa kwefolda kugcinwa kwi-ZIP yesingeniso.

Ingabe i-WMA izogcina isilinganiso esifanayo sesampula njenge-AMR?

Ngokungagqibekanga yebo (a 48 kHz AMR ikhiqiza 48 kHz WMA, a 44.1 kHz AMR ikhiqiza 44.1 kHz WMA). Ukusebenza kahle okuthile — isibonelo, ukusatshalaliswa kwe-96 kHz studio masters kuya ku-44.1 kHz WMA ukushaya i-CD, noma ukusatshalaliswa kwe-22 kHz voicemail kuya ku-44.1 kHz WMA — isilinganiso sesampula esiphansi sifaka ukusatshalaliswa kabusha kwekhwalithi ephezulu ye-SOX-style.

Ingabe ngizolungisa umsindo ku-AMR kuya ku-WMA?

Yebo — ukhetho lokujwayelekile-lokujwayelekile lufaka ITU-R BS.1770 / EBU R128 ukujwayelekile ku WMA kuphuma, libhekisa ku -14 LUFS (isizinda sokushayela) noma -16 LUFS (isizinda sepodcast) noma inani elijwayelekile. Lisetshenziswa uma liguqula amabhayisikobho ngezinga lokuphatha elihlukile ku WMA dlala.

Ingabe i-WMA izodlala ku-stereo yemoto yami / iPod / Sonos / isikhulumi se-Bluetooth?

I-MP3 idlala ngokugcwele kuwo wonke amadivayisi ayenziwe eminyakeni edlule engu-20. I-AAC idlala ku-Apple, ku-Android, ku-Sonos, nama-stereo emoto yamanje. I-FLAC idlala ku-Sonos ne-Android edlule, ingcono kakhulu kuma-iPods adala. I-WAV idlala kuwo wonke amadivayisi kodwa ifayela likhulu. I-idivayisi-yesihluthulelo sokukhuphuka ikhetha i-WMA codec ephephile ye-platform oyicacisile.

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 nezinsiza zomculo eziku-inthanethi.
