WMA kuya AMR Imibuzo Evame Ukubuzwa Yokuguqulwa

Ngiguqula kanjani umsindo WMA ube AMR ngaphandle kokulahlekelwa ukhwalithi?

Layisha phezulu ihele WMA futhi umguquli wethu uzokhetha i AMR codec / i-bitrate ehambisanayo necebo. Injongo engalahleki (AMR = WAV / FLAC / ALAC) igcina yonke isampula; injongo elahlekile (AMR = MP3 / AAC / OGG) iphutha liyi-192 kbps ecacile yencwadi yezwi elikhulumayo kanye neminye imiculo.

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, ukukopisha i-AMR kusuka kulo kunciphisa ukudluliswa okuphindiwe ngokuphelele. 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 ngaphezu kwe-audio spectrum ephelele.

Ingabe izihloko zengoma yami nesithombe se-albhamu sizohlala isikhathi eside uma ngiguqula 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 eliphawulwe, noma phinda uphawule 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 ku-channel ehlukile ihamba lapho lokhu kwenziwa.

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 ongayikhuphula wena, ongayirekhoda, noma ongayithenga ngaphandle kokuvikelwa iguqulwa 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.

Ihele AMR lisebenzisa i-bitrate enjani?

Iphutha ngu-192 kbps ku AMR olahlekelwayo; udlulisa-nge- AMR ongenalutho. Nciphisa ku-320 kbps ku-audiophile noma ku-64-96 kbps ku-audiobooks ekhuluma-magama (icacile ku-voice, ihlukanise ubukhulu befayela ngamaphesenti).

Ingabe ukusuka ku WMA kuya ku AMR kuzonciphisa ubunjani bomsindo wami?

Uma WMA ilahlekelwa futhi AMR ayilahleki (isibonelo MP3 → WAV), ihele AMR alingcono kuna WMA — awukwazi ukubuyisela imininingwane esele ilahlekile. Uma WMA ilahlekelwa futhi AMR ayilahleki, cabanga ukuthi i-AMR codec izocindezela futhi; ku-192 kbps lokhu kucacile kunoma iyiphi ingxenye.

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

Yebo — isihloko, umculi, i-album, unyaka, inani le-track, i-album art, nama-chapter markers (abalulekile kuma-audiobooks) afundwa kusuka ku-WMA futhi abhalwe ku-AMR ibhokisi lapho i-AMR ifomu lixhasa amathegi. Ukwakhiwa kwe-audiobook M4B kuhamba-hamba ku-M4B ne-AAX → M4B output.

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?

Ngokuzenzakalela yebo (48 kHz WMA → 48 kHz AMR). Uma ufuna uku-downsample ukuhambisana (isibonelo 96 kHz → 44.1 kHz yokushaya i-CD) isinqumo esiphezulu sesampula-rate sikwenza lokhu ngekhwalithi ephezulu yoku-resamply.

Ingabe ngizolungisa umsindo ku-WMA kuya ku-AMR?

Yebo — ukhetho lokujwayelekile-lokujwayelekile lufaka ITU-R BS.1770 / EBU R128 ukujwayelekile ku AMR kuphuma, libhekisa ku -14 LUFS (isizinda sokushayela), -16 LUFS (isizinda sepodcast), noma -23 LUFS (isizinda sencwadi yezwi). Kuhle uma uguqula amabhayisikobho ngezinga lokuphatha elihlukile.
