MP3 Imibuzo Evame Ukubuzwa Yokuguqulwa

Yini ihele MP3?

I-MP3 (i-MPEG Audio Layer III) iyifomethi yokubhala ikhodi yomsindo yedijithali esebenzisa ukucindezelwa kwedatha okulahlekile.

Ingabe ubuhle bulahlekile kuhele MP3?

Noma yini encoder yakuqala ekhetha ukuyisusa, futhi ayikwazi ukubuyiselwa. MP3 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. MP3 ilahlekelwa: imodeli ye psychoacoustic isusa iziqongo ezingezona ezivamile, ezivame ukuba ngu-128 kuya ku-320 kbps.

Kungani ama-CD rippers ephutha li MP3?

Ngenxa yokuthi kwakuyisimo esikwenza umculo ulungele ihardware abantu abakhona, futhi okuzenzakalelayo kuqinile isikhathi eside ngemuva kokungasebenzi kahle. I-library eqoshwe yilokho okuvame ukukhethwa eminyakeni edlule ngaphezu kokukhetha mayelana nomuzingo. Ukuqoshwa kabusha kusuka kumadiski kunikeza umphathi ongcono; ukushintshanisa okunye okukhona akukwazi, ngoba imingwane yokuqala edlulele ayikho kwifayela lokubuyisela. MP3 yi MPEG-1 Audio Layer III, eqediwe ngo-1993, futhi ikhona ifomethi yomsindo ekwazi ukuconywa ngokugcwele.

Ingabe umculi, i-album nesithombe sokuzivikela ku MP3 yami sizohlala siguqulwa?

Bakwenza lapho ifomu eligunyaziwe linesizinda sokubeka. MP3 lithwala izithonjana nemisebenzi yezandla efakwe njengengxenye yefayela, futhi ukuguqulwa kwenza amakhophi ngaphesheya kwendawo elingaqondakalayo. Izithonjana ezingacindezelwanga ziyisinqumo - zicacisiwe ngaphambi kokuphawula kwakuyithemba elijwayelekile futhi zigcina cishe akukho, ngakho ithala eliguqulwe ngalo ndlela lifika njengedonga lemisindo engabizwanga.

Ingabe kubaluleke ukuthi MP3 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.

Ingabe MP3 izodlala ngokuqondile kwikhasi le-web?

Yebo. MP3 iphakathi kwefomethi yomsindo i-browser iyi-decode, ngakho ingafakwa kungxenyekazi yomsindo noma kumdlali wepodcast futhi isebenza kuwo wonke amathuluzi ngaphandle kweplugin noma ihele elibuyela emuva. Lokhu kwenza kube yinjongo yoshicilelo ephephile, futhi yilokho okuguqula ukurekhodwa okungekuhle kube yifomethi evame ukuba yindlela encane yokuyithola idlala kuwebhusayithi. Akukho lutho olushaya i-MP3 ngokuhambisana - i-car stereos, imishini ye-gym, i-DAPs ne-hardware eneminyaka engu-20 yonke ifunde ngaphandle kwemibuzo.

Yini i-bitrate okufanele ngiyiguqule amafayela ami MP3?

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 MP3 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 MP3?

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 MP3 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.

Yini ezoba nehele lami MP3 ngemuva kokuguqulwa?

Kususwa. Ukulayisha kanye nemiphumela eguqulwe zombili zihlala kumhlinzeki kuphela uma umsebenzi ufuna futhi zisuswa ngokuzenzakalela; ukudluliswa kuhamba nge HTTPS emigwaqweni emibini. Akukho muntu ofunda okuqukethwe, akukho okuhlobene, futhi akukho okudluliswa kunoma ubani. Uma ufuna ukuyeka ukulindela ukuhlanzwa okuzenzakalelayo, ukuvala umsebenzi kuzosusa amafayela ngokushesha.

Ingabe ukuguqula i-MP3 kuzothatha isikhathi esingakanani?

Ngokuvamile amasekondi. Amafayela amancane asebenza ngokushesha, futhi izimo ezithatha isikhathi esingokoqobo ziyizinto ezisebenza umsebenzi ongokoqobo: ukurekhodwa okude okudinga ukuphinde kwenziwe ukukopela ifreyimu ngefreyimu, idokhumende elihlolwe lihamba nge-character recognition, noma iqembu elikhulu kakhulu. lapho ukuguqulwa kuphinde kuhlanganise idatha ekhona ihlala ngokushesha kungakhathaliseki ukuthi ihele likhulu kangakanani, ngoba akukho okuzosuswa.
