3GP kuya AUDIO Imibuzo Evame Ukubuzwa Yokuguqulwa

Ngiyikhipha kanjani umsindo kusuka kuhele lami 3GP njenge AUDIO?

Layisha phezulu ihele 3GP futhi umguquli u-demuxes umsindo, bese uguqula ikhodi liyi AUDIO. Akukho sinqumo sevidiyo sesibili - umsindo obonakalayo ususwa ngokushesha ngakho ukukhishwa kusheshe kakhulu kunalokho okuphelele kokuphinde ukhodwe. I-3GP iyibhokisi le-3GPP elijwayelekile lefoni ephathekayo, lapho ividiyo idinga ukuhambisana ne-176x144 screen ne-2G data plan. Umsindo lapha yinjongo ejwayelekile: umguquli ukhipha umsindo futhi ukhetha ukukopela okudlalwa ngokubanzi.

Ingabe ukushintsha 3GP kuya ku AUDIO kuyingxenye yesithathu yokucindezela okulahlekile?

Yebo, futhi kufanelekile ukuhlela. Izifomethi zombili ziyi-lossy, ngakho-ke i-AUDIO 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-AUDIO kusuka kulo kunciphisa ukudluliswa okuphindiwe ngokuphelele. 3GP igcina H.263 noma MPEG-4 Ingxenye 2 ividiyo nge AMR narrowband ukukhuluma umsindo, zonke tuned for minimal bitrate hhayi quality. Iphutha lokuphuma ku MP3 ku 192 kbps, okucacile kumathuluzi amaningi futhi okufundeka nganoma iyiphi idivayisi.

Ingabe ngiyiphawula i AUDIO ngemininingwane yomuntu odlalayo ne-album?

Yebo, futhi kuyinzuzo engokoqobo ngaphezulu kwe 3GP, engeke ikwazi ukugcinwa kuphi naphi. AUDIO 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. Ukukhetha isiphetho ngokuzenzakalela kuyindlela ekhawulezayo uma konke ofunayo wusandi ngaphandle kwehele, ngaphandle kwesinqumo se-codec esidinga ukukwenziwa.

Yini i-bitrate yomsindo osetshenziswa yi-AUDIO ekhishwayo?

Izinga lokungena elijwayelekile le-lossy AUDIO yi-192 kbps, elicacile kumculo. Ungayisusa ku-320 kbps (audiophile) noma 96-128 kbps (ubizo / podcast / ifayela elincane). Izinga lokungena eliphansi livela ezinketho eziphezulu ngaphambi kokuba ucofe uguqule.

Ingabe ngizolahlekelwa ukhwalithi yomsindo uma ngisuka ku 3GP kuya ku AUDIO?

Uma AUDIO ingekho emdlalweni (WAV, FLAC), yonke imibiko igcinwa ngokugcwele. Uma AUDIO ingekho emdlalweni (MP3, AAC, OGG, Opus), i AUDIO codec icindezela kabusha umsuka womsindo — ku-192 kbps imiphumela icacile kuzo zonke izithako. Ukuya nge-lossy → akukho emdlalweni akusho ukubuyisela imininingwane ekhishwe.

Ingabe i-AUDIO yomsindo igcina isilinganiso sosampula sangaphambilini?

Ngokungajwayelekile yebo — umsindo we-48 kHz ku 3GP wakho uhlala u-48 kHz ku-AUDIO kuphuma. Ukukhuphula i-CD noma ukuhambisana nomdlali odala ungakhuphula isampula ku-44.1 kHz ngesampula-rate dropdown; isampula ephindayo isezingeni eliphakeme le-SoX.

Ingabe ngingakwazi ukukhishwa umsindo kusuka kuhele 3GP ku AUDIO ngeqembu elilodwa?

Yebo — susa ifolda ye 3GP amafayela futhi sizokhipha umsindo ngokuhambisana. Abasebenzisi bepremium bathola abasebenza ngokuhambisana; kuhele olungu-50 lohlelo lokhu kuyinto ehlukile phakathi kwemizuzu emihlanu nemizuzu eyisithupha.

Ingabe i-AUDIO izophawulwa ngesihloko / umculi / i-album metadata?

Uma i 3GP ithatha isiqephu noma i-metadata yokuhamba, sikopa isihloko / umculi / ama-album ama-fields ngaphakathi kwe AUDIO ibhokisi. Uma kungenjalo, i AUDIO iphuma ingaphawuliwe - sebenzisa umhleli wesihloko (Mp3tag, Picard) ngemuva kokuthumela ngaphandle ukuphawula okunethezeka.

Ingabe kuthatha isikhathi esingakanani ukukhishwa kwe-AUDIO umsindo kusuka ku-3GP ohora elilodwa?

Umsindo demux + ukukopela kushesha — 5 kuya ku-15% wesikhathi somthombo. Ihora le-1 3GP → AUDIO liphele ngo-3 kuya ku-9 imizuzu ku-pipeline ejwayelekile; i-premium parallelism isusa lokhu ngaphezu kwemisebenzi yeqembu.

Ingabe ngizokhipha kuphela isigaba se-3GP somsindo njenge-AUDIO?

Ingabe ihele lami 3GP liyimfihlo ngesikhathi sokukhipha umsindo?

Yebo - imodeli yobumfihlo efanayo njengezo zonke iziguquko: abasebenza ngokuzimela, akukho ukuhlolwa komuntu, ukususwa okuzenzakalelayo ngaphakathi kwemizuzu yokuqedela. Ifasitela lokugcina eliphelele litholakala ku /privacy/.

Sebenzisa isikhethi esithuthukisiwe "i-stream yomsindo" ukukhetha inhlamvu 0, 1, 2 ngokucacile, noma ubeke i AUDIO ibhokisi elixhasa i-multi-track output (FLAC, OGG).
