MP2 Imibuzo Evame Ukubuzwa Yokuguqulwa

Yini ihele MP2?

MP2 (MPEG-1 Audio Layer II) is an audio format commonly used in digital broadcasting.

Ingabe ubuhle bulahlekile kuhele MP2?

Noma yini encoder yakuqala ekhetha ukuyisusa, futhi ayikwazi ukubuyiselwa. MP2 icindezela ngokumodela lokho okungekuqaphela indlebe - imisindo ekhululekile ehlala ngaphansi kwezikhulu, iziqongo eziphezulu zokulalela - futhi isuse ngokuqhubekayo. Ku-bitrate ephephile engeke ikwazi ukulalela wonke umuntu. Okunye okungaba khona kubuyiselwa emuva, ngakho ukushintshana kufomethi engalahlekelwa yisimo samanje ngaphandle kokubuyisela okungaphambili. MP2 ilahlekelwa yinto kodwa isebenzisa isihlungi esilula kunaso iMP3, isebenza nge 192 kuya ku 384 kbps.

Kungani isofthiwe yokusakaza neyokubhala i insists ku MP2?

Ngenxa yokuthi i-chain yonke yakhiwa kuyo. Amaseva okudlala, amathuluzi we-DVD authoring kanye nezinhlelo zokungenisa zicacisiwe ngalesi sifomethi lapho ikhona, futhi imishini eneminyaka eyisithupha yokuphila kwenkonzo ayikwazi ukucaciswa kabusha. Amafayela aphuma kulezi zinhlelo yifomethi i-system yakhiwa ukukhishwa, hhayi ukhetho oluwenziwe ngumuntu odlule. MP2 inamandla amakhulu kakhulu ukuxazulula amaphutha ancane futhi ibiza kakhulu ukuwususa, ngakho-ke izintambo zokusakaza zihlala kuyo isikhathi eside ngemuva kokufika kweMP3.

Kungani ihele lami MP2 livela ngaphandle kwegama lesiqongo noma isithombe?

Ngenxa yokuthi ifomu alikho indawo efanele yokuzigcina. MP2 yacaciswa ngaso sonke isikhathi ngaso sonke isikhathi, ngaphandle kwendawo ejwayelekile yesihloko, i-album noma isithombe sokuzivikela, ngakho abadlali babuyela emuva ukukhombisa igama lefayela. Ukushintshana kufomethi ephawuliwe kwenza i-library ifinyeleleke — amathegi abhalwe ngesikhathi sokuguqulwa ngaphezu kokubuyiselwa, ngakho-ke cabanga ukugcwalisa noma yini engingakhombisi i-source. I-MP2 idinga i-bitrate engaphezulu kune-MP3 noma i-AAC ukuze ibe nekhwalithi efanayo futhi ayiziwa kusoftware eminingi yomsebenzisi.

Ingabe kufanele ngigcine amafayela amasha njenge MP2?

Uma nje kukhona okuthile okudingayo. Ifomethi ivuliwe, futhi akukho sidingo sokushintsha ingobo yomlando ongeke ukwenze kube nzima, kodwa akuyona indawo lapho ithuluzi noma umphumela uhamba khona. Kunoma yini entsha, ifomethi yamanje ayidingi lutho olungeziwe futhi ivimbela ukulandelana kwesifundo seminyaka emincane kusukela manje.

Ingabe ihele MP2 lingathwala i-5.1 surround mix?

Yebo - ifomu liphatha iziqhagamshelanisi ezingaphezu kwezingu-2 ngokufanele, ngakho-ke ukuhlanganisa okugqamile kugcina isakhiwo sesiqhingi saso ngaphandle kokucindezelwa kwe-stereo ngendlela efanele. Uma ukhuluma ngayo njenge-surround kuxhomekeka kukuphela kokuphela: umlayezo uzosusa wonke ama-channels, ifoni izocindezela phantsi ngesikhathi sokudlala ngaphandle kokukhathazeka. Ukushintshana ku-stereo-only format kwenza ukuthi ucindezelwe ngokuqhubekayo.

Ingabe kubaluleke ukuthi MP2 ingaphezu kweminyaka engu-30?

Ubudala bukhona akuyona inkinga - amafomethi amaningi onyaka akhona alungile, ngokucacile ngoba konke kudlule iminyaka eminingi ukuwafaka. Okubalulekile ukuthi unyaka uthathe isinqumo: amafayela amancane, amaprosesa aphansi, akukho nethiwekhi, futhi amakhono angeke afune umuntu. lapho amanani ahlala khona, ifomu lilungile. lapho ayikho, lena yisizathu sokushintsha. MP2 yi MPEG-1 Audio Layer II, i-layer edlule i-MP3 futhi yabe yi-audio standard ye-DVB ne-DAB broadcasting.

Kungani ihele MP2 alidlalwa kumsakazo wami?

Amabhuleki aqopha uhlu oluncane, oluqinile lwefomethi yomsindo futhi MP2 ungaphandle kwalo, ngakho ihele likhuphuka endaweni yokudlala noma umdlali ukhombisa iphutha. Isofthiwe yedesktop enesethingi se-codec esibanzi ivula ngaphandle kwezinkinga. Uma umsindo udlala kukhasi le-web, ukushintsha kuyinto elungile — akukho ukumiswa komdlali kuzongeza umbhalo oqoshiwe umbhukeli awuthumeli.

Yini i-bitrate okufanele ngiyiguqule amafayela ami MP2?

Uhlu lwendawo esiya kuyo, hhayi umsuka. Ukudlalwa kwengoma, 256 kuya ku-320 kbps kucacile kuwo wonke umuntu olalelayo; ukukhuluma nokulalela ipodcasts, 96 kuya ku-128 kbps kuningi futhi kushiya ihele ngaphesheya. Ukungenisa umsindo ngaphezu komsuka we-bitrate kulahlekile isikhala — kugcina umsindo osele udlulele nge-lossy pass futhi akubuyiseli lutho umngenisi wokuqala olahlekile.

Ingabe ukushintshana kushintsha isilinganiso sesampula se MP2 yami yomsindo?

Akunakwenzeka ngaphandle kokuthi ucela. Ukuguquka kugcina umsuka wezinga — 48 kHz uhlala 48 kHz, 44.1 kHz uhlala 44.1 kHz — ngoba ukusatshalaliswa kabusha kubiza kakhulu futhi akusebenzi uma akukho okudingayo. Iziphuzo zikhona: ama-CD omsindo adinga u-44.1 kHz, abanye abadlali behardware abadala bamukela okuthile, futhi amapayipi omsindo avame ukudinga u-16 kHz. Misela izinga ngokucacile kulezi zinkinga bese ushiya icala linye.

Ingabe ngingenza ngiphinde ngibize isiqephu endaweni yokushintsha MP2?

Kunzima kakhulu, futhi kufanelekile ukuqonda ukuthi kungani: isithonjana siyisihloko, ngenkathi ama-bytes ngaphakathi kufakwe ngefomethi eyodwa ekhethekile. Ukushintsha igama kwenza ihele igama lakhe lithembisa okuthile okuqukethwe kwayo akusho ukunikela, futhi noma yini evula ihele noma liyiphoqa noma liyifunda kabi. Ukuphela kwephutha elincane yifomethi ezimbili ezikhona ngokusemthethweni ibhokisi elifanayo ngaphansi kwezinhlamvu ezahlukene — futhi ngisho lapho ukuphinda uphinde

Ingabe ngiguqula isibaya esigcwele se MP2 amafayela ngasikhathi sinye?

Nge-akhawunti, yebo — khiphana ndawonye futhi zibekwe njengemisebenzi eyodwa endaweni yokuphathwa ngayinye ngasikhathi sinye, ngezinhlelo ezifanayo ezisetshenziswa ngaphesheya kweqembu futhi izimpendulo zibuyiselwe ndawonye. Ukuguquka okumahhala kusebenza ihele elilodwa ngasikhathi sinye (amathuluzi okuxhuma athatha amabini); i-plan ekhokhelwa yilokho okuvulela ukuqhubekela phambili kweqembu kanye nobukhulu bomgwaqo wefayela ngalinye, okukwenza ukuguquka kwehele lonke le-archive kube lula.
