AMR kuya MP3 Imibuzo Evame Ukubuzwa Yokuguqulwa

Ihele MP3 lisebenzisa i-bitrate enjani?

I-lossy MP3 ikhodwe ku-192 kbps ngokuzenzakalela. Uhlelo lwekhwalithi yomsindo lunikeza futhi 320 kbps ukuqinisekisa ukhwalithi enhle kanye ne-128 kbps ukuqinisekisa ifayela elincane. I-lossless MP3 (WAV, FLAC) i ignore i-bitrate futhi igcine yonke isampula.

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.

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

Amafayela amaningi emisebenzini eyodwa adinga iphrojekthi ekhokhelwa. Ukusetshenziswa okumahhala kuyisifayela esisodwa ngasinye sokuguqulwa, ukuguqulwa okufanayo ngehora. Kuphrojekthi ekhokhelwa ungangeza amafayela amaningi kumsebenzi owodwa, bese ulanda impendulo ngayinye yayo noma zonke ku-ZIP eyodwa.

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?

Akunalokhu kulesi simo. Umguquli awunaso isilungiselelo sokulungiswa kokulungiswa futhi ushiya izinga njengelikhona. Ukwenza umsindo ulinganise, sebenzisa i-MP3 eqediwe ngethuluzi lokujwayelekile kule ndawo.

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

MP3 idlala cishe kuwo wonke indawo. AAC idlala ku Apple amadivayisi, Android amafoni amaningi kanye Sonos. FLAC idlala ku Sonos ne Android kodwa hhayi ku iPods older, futhi WAV idlala ku cishe konke kodwa yenza amafayela amakhulu. Akukho isisetshenziswa preset kulesi khasi, ngakho khetha ifomu inhloso umdlali wakho uxhasa.

Ingabe ihele lami AMR liyimfihlo ngesikhathi sokuguqulwa?

Yebo. Akukho muntu olalela noma ohlanganisa umsindo, obalulekile kuma-library wencwadi yomsindo, futhi amafayela AMR alayishwe phezulu kanye nekhophi labo eliguquliwe lisuswa ngokuzenzakalela cishe amahora angama-24 ngemuva kokuguqulwa.

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.
