MPEG kuya MP3 Imibuzo Evame Ukubuzwa Yokuguqulwa

Ngiyikhipha kanjani umsindo kusuka kuhele lami MPEG njenge MP3?

Layisha phezulu ihele MPEG futhi umguquli ukhipha umsindo, bese uguqula ikhodi liyi MP3. Akukho sikhathi sevidiyo sesibili - umsindo obonakalayo ususwa ngokushesha ngakho-ke ukukhishwa kusheshe kakhulu kunalokho okuphelele kokuphinde uguqule ikhodi.

Yini i-bitrate yomsindo osetshenziswa yi-MP3 ekhishwayo?

Izinga le-bit elimiselwe le-lossy MP3 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 MPEG kuya ku MP3?

Umsindo demux + ukukopela kushesha — 5 kuya ku-15% yesikhathi somthombo. Ihora le-1 MPEG → MP3 liphele ngemizuzu engu-3 kuya ku-9 ku-pipeline ejwayelekile; i-Premium parallelism isusa lokhu ngaphezu kwemisebenzi yeqembu.

Ingabe ngizokhipha kuphela isigaba se MPEG somsindo njenge MP3?

Akunalesi sisetshenziswa ngokuqondile — khipha umsindo wonke njenge MP3, 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 MPEG 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 MP3 linezingcindezi ezingenalutho lapho i MPEG ikhona umsindo?

MP3

Amafayela e-MP3 asebenzisa ukucindezela okulahlekile ukunciphisa usayizi wefayela ngenkathi kugcinwa ikhwalithi yomsindo eyamukelekayo kubalaleli abaningi.
