MP3 Imibuzo Ebuzwa Rhoqo Ngokuguqula

Yintoni i-MP3 yefayili yesandi?

I-MP3 yifomati yesandi elahlekile. Umkhokeli ususa ukuphindaphinda okungalunganga nesandi esifihlakeleyo ukufezekisa ubungakanani befayili obumalunga neshumi le-uncompressed equivalent. Ukunxulumana kwakhona i-MP3 kwifomati enye elahlekile kwenza ukuba umgangatho ulahleke; guqula ukusuka kwi master engalahleki xa kunokwenzeka.

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 engazivakalayo kuninzi lwaba bonke. Into eyiyo ayitshintshi, ngoko ukuguqula kwifomati engalahleki igcina iimeko zangoku kunokuba ibuyisele ioriginal. I-MP3 ilahlekile: imodeli ye-psychoacoustic isusa ukuphindaphinda indlebe ayikwazi ukuqaphela, ihlala kwi-128 ukuya kwi-320 kbps.

Kutheni izixhobo zokurhoxisa zimiselwe ku MP3?

Kuba igcina konke idiski iqulathe ngaphandle kokufuna ukushiya nantoni na - yonke ulwimi lwesandi, yonke ingoma yesihloko esingaphantsi, uluhlu lwesithuba - kwifayile enye. Oku kukungagqibekanga okulungileyo xa injongo ikopi ethembekileyo yokuqala, kwaye okubi xa ifayile kufuneka idlala kwisixhobo esiqonda kuphela ubeko lokunikezelwa. Akukho nto ibetha iMP3 ekusebenzeni kwayo - iistereo zemoto, izixhobo zegym, iiDAPs kunye nezixhobo zekhompyutha ezineminyaka engama-20 ubudala zonke zifunda ngaphandle kwemibuzo.

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. I-MP3 yi-MPEG-1 Umphezulu Wosandi III, egqityiwe ngo-1993, kwaye ihlala i-format yesandi ekwazi ukucoda ngokupheleleyo ekhoyo.

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.

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 kusezantsi isithuba - 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 ikhululekileyo ngaphandle kokuba.

Ndiyiguqule njani i-MP3 ukuze ndiyisebenzise?
