AMR kuya OGG Imibuzo Evame Ukubuzwa Yokuguqulwa

Ngiguqula kanjani umsindo AMR ube OGG ngaphandle kokulahlekelwa ukhwalithi?

Layisha phezulu ihele AMR futhi umguquli ukhetha OGG i-codec / i-bitrate ehambisana neprofayili yomsuka. I-lossless OGG (WAV / FLAC / ALAC) igcina yonke isampula ngokugcwele; i-lossy OGG (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-Vorbis ngaphakathi kwe-OGG ilahlekile futhi isebenzisa i-bitrate eguqukayo ngokuzenzakalela, ngakho-ke ukhwalithi ibekwe njengezinga ngaphandle kwe-kbps eqinile.

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.

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.

Ihele OGG liphele nini nge-bitrate?

Iphutha 192 kbps ku OGG olahlekelwayo; dlula-nge- OGG 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 OGG kuzonciphisa kakhulu izinga lami lomsindo?

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

Ingabe i-AMR kuya ku-OGG 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 OGG ibhokisi. ID3v2 (MP3), amazwana we-Vorbis (OGG, FLAC), ama-MP4 atoms (AAC, M4A), RIFF INFO (WAV), ama-iXML chunks wonke ama-maps ngokuhlanzekile. OGG yi-Xiph.Org container, ehlala igcina umsindo we-Vorbis, yakhiwa ngo-2000 njengenye indlela engavunyelwanga ye-MP3.

Ingabe ngingenza ukuguqulwa kwekhulu le AMR amafayela abe OGG?

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-OGG izogcina isilinganiso esifanayo sesampula njenge-AMR?

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

Ingabe ngizolungisa umsindo ku-AMR kuya ku-OGG?

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

Ingabe i-OGG 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-OGG 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.
