AMR kuya MP3 Imibuzo Evame Ukubuzwa Yokuguqulwa

Ngiguqula kanjani umsindo AMR ube MP3 ngaphandle kokulahlekelwa ukhwalithi?

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

Ingabe ukushintsha AMR kuya ku MP3 kuyingxenye yesithathu yokucindezela okulahlekile?

Yebo, futhi kufanelekile ukuhlela. Izifomethi zombili ziyi-lossy, ngakho-ke i-MP3 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-MP3 kusuka kulo kunciphisa ukudluliswa okuphindiwe ngokuphelele. 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. MP3 ilahlekelwa: imodeli ye psychoacoustic isusa iziqongo ezingezona ezivamile, ezivame ukuba ngu-128 kuya ku-320 kbps.

Ingabe ngiyiphawula i MP3 ngemininingwane yomuntu odlalayo ne-album?

Yebo, futhi kuyinzuzo engokoqobo ngaphezulu kwe AMR, engeke ikwazi ukugcinwa kuphi naphi. MP3 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. Akukho lutho olushaya i-MP3 ngokuhambisana - i-car stereos, imishini ye-gym, i-DAPs ne-hardware eneminyaka engu-20 yonke ifunde ngaphandle kwemibuzo.

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 MP3 lisebenzisa i-bitrate enjani?

Iphutha ngu-192 kbps ku MP3 olahlekelwayo; udlulisa-nge- MP3 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 AMR kuya ku MP3 kuzonciphisa ubunjani bomsindo wami?

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

Ingabe i-AMR kuya ku-MP3 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-AMR futhi abhalwe ku-MP3 ibhokisi lapho i-MP3 ifomu lixhasa amathegi. Ukwakhiwa kwe-audiobook M4B kuhamba-hamba ku-M4B ne-AAX → M4B output.

Ingabe ngingenza i-batch yokuguqula amahele angama-AMR abe MP3?

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-MP3 izogcina isilinganiso esifanayo sesampula njenge-AMR?

Ngokuzenzakalela yebo (48 kHz AMR → 48 kHz MP3). 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-AMR kuya ku-MP3?

Yebo — ukhetho lokujwayelekile-lokujwayelekile lufaka ITU-R BS.1770 / EBU R128 ukujwayelekile ku MP3 kuphuma, libhekisa ku -14 LUFS (isizinda sokushayela), -16 LUFS (isizinda sepodcast), noma -23 LUFS (isizinda sencwadi yezwi). Kuhle uma uguqula amabhayisikobho ngezinga lokuphatha elihlukile.

Ingabe i-MP3 izodlala kwi-stereo yemoto yami / i-iPod / i-app yencwadi yezwi?

MP3 idlala emhlabeni wonke. AAC idlala ku Apple, ngaphezu Android, Sonos. FLAC idlala ku Sonos ne Android, ngaphezu kahle ku iPods edlule. M4B audiobooks dlala ngesigaba ukuzulazula ku iOS Books, Audiobookshelf, kanye Smart Audiobook Player. Izinto ezikhethwayo ezisezingeni eliphezulu zifaka idivayisi imise.

Ingabe ihele lami AMR liyimfihlo ngesikhathi sokuguqulwa?

Yebo — amafayela alayishwe phezulu AMR aqhubekelwa phambili abasebenza ngokuzimela futhi acishwe ngaphakathi kwemizuzu. Asikwazi ukudlala, ukugcina, noma ukuhlanganisa okuqukethwe kwesandi. Kubalulekile kakhulu uma usebenza nama-library wencwadi yesandi.

AMR

I-AMR iyi-codec yokukhuluma ehlobene nokurekhodwa kwezwi kanye nokuxhuma, ngakho-ke umculo uzwakala ubuhlungu kulo.

MP3

Amafayela e-MP3 asebenzisa ukucindezela okulahlekile ukunciphisa usayizi wefayela ngenkathi kugcinwa ikhwalithi yomsindo eyamukelekayo kubalaleli abaningi.
