3GP kuya AUDIO Imibuzo Evame Ukubuzwa Yokuguqulwa

Ngiyikhipha kanjani umsindo kusuka kuhele lami 3GP njenge AUDIO?

Layisha phezulu ihele 3GP futhi umguquli ukhipha umsindo, bese uguqula ikhodi liyi AUDIO. Akukho sikhathi sevidiyo sesibili - umsindo obonakalayo ususwa ngokushesha ngakho-ke ukukhishwa kusheshe kakhulu kunalokho okuphelele kokuphinde uguqule ikhodi. 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, uku-encoding i-AUDIO kusuka kulo kunciphisa ukudlula 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 kokufaka isandla. 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 le-bit elimiselwe le-lossy AUDIO yi-192 kbps, elicacile kumculo. Ungashintsha ufike ku-320 kbps (audiophile) noma 96-128 kbps (ubizo / ipodcast / ifayela elincane). Izinga le-bit eliphansi livela ezinketho eziphezulu ngaphambi kokuba ucofe uguqule.

Ingabe ngizolahlekelwa ubunjani besandi uma ngisuka ku 3GP kuya ku AUDIO?

Uma AUDIO ingekho lutho (WAV, FLAC), yonke isampula igcinwa ngokugcwele. Uma AUDIO ingekho lutho (MP3, AAC, OGG, Opus), i-AUDIO codec icindezela kabusha umsuka womsindo — ku-192 kbps imiphumela icacile cishe kuzo zonke izithako. Ukuya kwe-nothing → akukho lutho akugcini nje ngokubuyisela imininingwane ekhishwe.

Ingabe umsindo AUDIO ugcina isilinganiso sokuqala sesampula?

Ngephutha yebo — 48 kHz umsindo ku 3GP wakho uhlala 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 ngizokhipha umsindo kusuka ku 3GP amafayela amaningi kuya ku AUDIO ngeqembu elilodwa?

Yebo — susa ifolda ye 3GP amafayela futhi sizokhipha umsindo ngokufanayo. Abasebenzisi abaphezulu bathola abasebenzi abafanayo; kuhele olune-50-batches lokhu kuyinto ehlukile phakathi kwemizuzu emihlanu nemizuzu eyisithupha.

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

Uma i 3GP ithatha isiqephu noma i-stream metadata, sikopa isihloko / umculi / ama-album ama-fields kwi-AUDIO container. Uma kungenjalo, i-AUDIO iphuma ingaphawuliwe — sebenzisa umhleli wesihloko (Mp3tag, Picard) ngemuva kokuthumela ngaphandle ukuze uphawulwe ngokunethezeka.

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

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

Ingabe ngizokhipha kuphela isigaba se 3GP somsindo njenge AUDIO?

Akunalesi sisetshenziswa ngokuqondile — khipha umsindo wonke njenge AUDIO, bese usebenzisa /audio-trim/ noma /audio-cutter/ ukucisha inqwaba. Indlela yezinhlangothi ezimbili ivame ukuba isheshe kunalokho okwenziwayo futhi ikunikeza ukulawula okucacile kwe-waveform-level.

Ingabe ihele lami 3GP liyimfihlo ngesikhathi sokukhipha umsindo?

Yebo - imodeli yobumfihlo efanayo njengezo zonke iziguqulo: abasebenzi abahlukanisiwe, akukho kuhlolwa komuntu, ukususwa okuzenzakalelayo ngaphakathi kwemizuzu yokuqedwa. Ifasitela lokugcinwa okuningiliziwe ku /privacy/.

Kungani ihele AUDIO linezingcindezi ezingenalutho lapho i 3GP ikhona umsindo?

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

3GP

I-3GP iyifomethi yesitsha semultimedia eyenzelwe omakhalekhukhwini be-3G. Ingagcina idatha yomsindo nevidiyo futhi ivamise ukusetshenziselwa ukudlalwa kwevidiyo yeselula.
