MP3 Imibuzo Ebuzwa Rhoqo Ngokuguqula

Yintoni ifayili MP3?

I-MP3 (MPEG Audio Layer III) yifomathi yedijithali yekhowudi yesandi esebenzisa ucinezelo lwedatha olulahlekileyo.

Ingaba umgangatho sele ulahlekile kwifayili MP3?

Into na leyo ikhowudi yokuqala yagqiba ukuyisusa, ayikwazi ukubuyiselwa. MP3 icindezela ngokuyila into ethe indlebe ayizukuyiqaphela - iingoma ezimdaka ezihlala phantsi kwezi zikhulu, ukuphindaphinda kumazantsi okuva - kwaye isuse ngokusisigxina. Kwi bitrate elungileyo engaziwayo kuninzi lwaba bonke. Into engayiyo ibuyiselwa, ngoko ukuguqula kwifomati engalahleki igcina iimeko zangoku kunokuba ibuyisele eyakuqala. I-MP3 ilahlekile: imodeli ye-psychoacoustic isusa ukuphindaphinda indlebe ayikwazi ukuqaphela, ihlala kwi-128 ukuya kwi-320 kbps.

Kutheni i-CD rippers imiselwe ku MP3?

Kuba yayikucwangciso elifumene uluhlu lwengoma lulungele isixhobo esinamandla abantu abazange babenayo, kwaye okungagqibekanga kutyibilika ixesha elide emva kokuba umda uhambe. Incwadi erhoxisiweyo ngoko ihlala igqiba ikhetho leminyaka edlulileyo kunokuba igqibe malunga nengoma. Ukuphinda urhoxisiwe kwi diski kunika umphathi ongcono; ukuguqula into oyinayo sele ayikwazi, kuba inkcukacha yesiqendu sokuqala esilahlekileyo ayikwifayile yokubuyisela. I-MP3 yi-MPEG-1 Umphezulu Wosandi III, egqityiwe ngo-1993, kwaye ihlala i-format yesandi ekwazi ukucoda ngokupheleleyo ekhoyo.

Ingaba umculi, i-albhamu kunye nomfanekiso wesiqulathi seefayili kwi MP3 yam uhlala uguqulwa?

Ziyenza apho ifomati yenjongo ikhona indawo yokuzibeka. MP3 ithatha iimpawu kunye nomsebenzi womzobi ofakwe ngaphakathi njengenxalenye yefayile, kwaye uguqulelo lukopa ngaphezulu kwendawo nganye eqondayo indawo engqongileyo. Iimpawu ezingaqhotyoshwanga ziyimfuneko - zacaciswa phambi kokuba uphawulo lube lulindeleko oluqhelekileyo kwaye zigcine akukho nto, ngoko ithala leencwadi eliguqulelwe ngendlela lifika njengedonga lweengoma ezingabonakaliyo.

Ingaba kubaluleke na ukuba u MP3 uneminyaka engaphezu kweeminyaka ezimashumi amathathu ubudala?

Ubudala ngokwalo alukuyingxaki - iifomati ezininzi ezivela kulo nyaka zihlala zilungile, ngokucacileyo ngenxa yokuba konke kwakuba neminyaka emininzi yokuzisebenzisa. Okubalulekileyo kulapho ixesha licinga khona: iifayile ezincinci, abaqhubi abancinci, akukho msebenzi womnatha, kunye neempawu ezingafunekiyo. apho ezi zinto zicinga khona, ifomati ilungile. apho azisebenzi, le yisizathu sokuguqula.

Ingaba i-MP3 iyadlala ngokuthe ngqo kwiphepha le-web?

Ewe. MP3 iphakathi kwefomati zesandi ezimfutshane ezisuka kumkhangeli zincwadi, ngoko ke ingaqhutywa kwinxalenye yesandi okanye kumdlali wepodcast kwaye isebenza kuwo onke amacala ngaphandle koplugin okanye ifayile yokubuyisa. Oku kwenza ukuba ibe yinjongo yoshicilelo olukhuselekileyo, kwaye yiyo loo nto ukuguqula ushicilelo olunobungozi kule fomati kuqhelekileyo indlela efutshane yokufumana idlala kwiwebhusayithi. Akukho nto ibetha iMP3 ekusebenzeni kwayo - iistereo zemoto, izixhobo zegym, iiDAPs kunye nezixhobo zekhompyutha ezineminyaka engama-20 ubudala zonke zifunda ngaphandle kwemibuzo.

Yintoni i-bitrate ekufuneka ndiyiguqule iifayile zam MP3?

Uthelekiso lwendawo ebekwe kuyo, hayi umthombo. Kwingoma, 256 ukuya 320 kbps icacile kuye wonke umntu ofundayo; kwilizwi kunye nepodcasts, 96 ukuya 128 kbps ininzi kwaye iqulethe ifayile kwakhona. Ukunxulumana ngaphezulu komthombo we bitrate kusiphumo sokungasebenzi kakuhle kwesithuba - igcina ngokunyanisekileyo isandi esisele sidlula kwindlela elahlekile kwaye ayibuyiseli nto ikhowudi yokuqala elahlekile.

Ingaba ukutshintshela kutshintsha umyinge wesikhokelo sesandi sam MP3?

Ayinaku ukuba ungacela ukuba ikwenze. Uguqulelo lugcina umyinge wombhalo ophambili - 48 kHz uhlala 48 kHz, 44. 1 kHz uhlala 44. 1 kHz - kuba ukuphinda uthathe isampuli kubiza kakhulu umgangatho oncinci ngaphandle koncedo xa akukho nto ifunayo. Izixabiso ziyanele: ii CD zesandi zifuna 44. 1 kHz, abanye abadlali be hardware abadala bavuma akukho nto enye, kwaye imibhobho yelizwi ifuna 16 kHz. Cwangcisa umyinge ngokucacileyo kwezi meko kwaye uyishiye ikhululekile ngaphandle kokuba.

Ndingayinika kwakhona igama elipheleleyo lesiqendu endaweni yokuguqula i MP3?

Akukho nanye, kwaye ifanele ukuqonda kutheni: unikezelo luphawu, ngelixa i bytes ngaphakathi zidityaniswe kwifomati ekhethekileyo. Ukuphinda ubize ifayile ivelisa ifayile igama layo lithembisa into imixholo yayo ayinikezeli, kwaye nantoni na evula ifayile okanye ilahlekile ifayile okanye ifunda ngokungachanekanga. Ukuphela kwendlela efutshane kuhlobo olubini oluyinyani ibhokisi efanayo phantsi kwegama elahlukileyo - kwaye nalapho ukuphinda ubhale ngokuchanekileyo kukhuselekile kunegama elahlukileyo.

Ndingaguqula isiqulathi seefayili esipheleleyo se MP3 iifayili ngenye indlela?

Nge akhawunti, ewe - shiya ngaphaya kunye kwaye zifolwa njengemisebenzi enye endaweni yokuphathwa enye ngexesha, ngemimiselo efanayo esetyenziswa kwiqela kunye neziphumo ezibuyiselweyo kunye. Uguqulelo oluzenzekelayo luqhuba ifayile enye ngexesha (izixhobo zokudibanisa zithatha ezimbini); inkqubo ehlawulweyo ivula uqhubekeko lweqela kunye nobukhulu befayile nganye umda, owenza uguqulelo lwefayile yonke yovimba isebenziseke.

Yintoni eyenza i-MP3 yam ifile emva kokuguqula?

Icinywa. Ulayisho phezulu kunye nempumelelo eguqulweyo zombini zihlala kumncedisi kuphela kude kube umsebenzi ufuna ukuba zigcinwe kwaye zisuswa ngokuzenzekelayo; unikezelo luya phezulu kwi HTTPS kumgca ngamnye. Akukho mntu ufunda imixholo, akukho nto iqulathe isiqulathi seefayili, kwaye akukho nto igqityiwe komnye umntu. Ukuba awufuni ukulindela ucoci oluzenzekelayo, ukuvala umsebenzi ususa iifayile ngokuzenzekelayo.

Ithatha ixesha elingakanani ukutshintsha i-MP3?

Iiyure. Iifayile ezincinci zisebenza ngokukhawuleza, kwaye iimeko ezithatha ixesha elibonakalayo zizo ezizenza umsebenzi obonakalayo: ushicilelo olude olufuna ukuphinde kwenziwe ukukhowuda iframe nge frame, uxwebhu olushayiniweyo oluya kukwazisa uphawu, okanye iqela elikhulu kakhulu. apho uguqulelo luphinda lujikeleze okanye luphinde lupakishe i data ekhoyo ihlala ikhawuleza nokuba ifayile incinci kangakanani na, kuba akukho nto iguqulelwe kwikhowudi.
