AMR kuya OGG Imibuzo Evame Ukubuzwa Yokuguqulwa

Yini i-bitrate ongayisebenzisa ihele elivela ku-OGG?

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

Ingabe ukushintsha AMR kuya ku OGG kuyingxenye yesithathu yokucindezela okulahlekile?

Yebo, futhi kufanelekile ukuhlela. Izifomethi zombili ziyi-lossy, ngakho-ke i-OGG 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-OGG kusuka kulo kunciphisa ukudlula okuphindiwe ngokuphelele. 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-Vorbis ngaphakathi kwe-OGG ilahlekile futhi isebenzisa i-bitrate eguqukayo ngokuzenzakalela, ngakho-ke ukhwalithi ibekwe njengezinga ngaphandle kwe-kbps eqinile.

Ingabe ngiyiphawula i OGG ngemininingwane yomuntu odlalayo ne-album?

Yebo, futhi kuyinzuzo engokoqobo ngaphezulu kwe AMR, engeke ikwazi ukugcinwa kuphi naphi. OGG 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-OGG Vorbis ishaya i-MP3 nge-bitrate elinganayo futhi ayihambisani nezindleko zokugunyazwa, ngakho-ke ama-engine wemidlalo kanye nesofthiwe yomthombo ovulekile yasebenzisana nayo.

Ingabe i-OGG izodlala emoto yami noma ku-hardware edala?

Ngokuvamile akunjalo. AMR i-decoded yinoma yini, kufaka phakathi izimoto eziphezulu nezidlali ezikhulu; OGG 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. OGG inezinsizakusebenza ezincane — amastereo wemoto, ama-iPods adala kanye nama-TV amaningi ngeke abone ifayela ngaso sonke isikhathi.

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 OGG kuzonciphisa ubunjani bomsindo wami?

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

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

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-OGG izogcina isilinganiso esifanayo sesampula njenge-AMR?

Ngephutha yebo — 48 kHz AMR ihlala 48 kHz ku OGG. 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 AMR ku OGG?

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

Ingabe OGG yami izodlala ku-car stereo, iPod, ne-Sonos?

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.

AMR

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