MP2 Imibuzo Ebuzwa Rhoqo Ngokuguqula

Yintoni ifayili MP2?

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

Ingaba umgangatho sele ulahlekile kwifayili MP2?

Into na leyo ikhowudi yokuqala yagqiba ukuyisusa, ayikwazi ukubuyiselwa. MP2 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. MP2 ilahlekile kodwa isebenzisa ibanki yecebo lokucoca ulwelo elilula kune MP3, eqhelekileyo isebenza kwi 192 ukuya kwi 384 kbps.

Kutheni inkqubo yokusebenza yokusasaza nokubhala ifuna MP2?

Kuba umbhobho wonke wakhiwa kuwo. Abancedisi abadlalayo, i DVD ebhaliweyo isixhobo kunye nenkqubo yokuthatha ispecified malunga nale fomati xa yayikhona, nezixhobo ezineminyaka emibini yobomi benkonzo ayikwazi ukucaciswa kwakhona. Iifayile eziphumayo ezinkqubo zifomati inkqubo yakhiwa ukuba ikhuphe, hayi ukhetho umntu owenzayo ngoku. I-MP2 inamandla kakhulu ekuphumezeni iimpazamo ze-bit kwaye ibiza kakhulu ukuyikhupha, oko kubangela ukuba iinqanawa zokusasaza zihlale kuyo ixesha elide emva kokuba i-MP3 ifike.

Kutheni le nto ifayili yam MP2 ivela ngaphandle kwegama lengoma okanye ubugcisa?

Kuba ifomati ayikho naphi na ukugcina. MP2 yacaciswa ngaphaya kwesandi sayo, ngaphandle kwendawo eqhelekileyo yesihloko, i-albham okanye umfanekiso wesiqulathi seefayili, ngoko abadlali babuyela umva ukuboniswa kwegama lefayili. Ukutshintsha kwifomati ephawulweyo kwenza ithala leencwadi likwazi ukutyelela - ii-tags zibhalwe ngexesha lokuguqula, kunokuba zibuyiselwe, ngoko lindele ukugcwalisa nantoni na eyamkelwa ngumbhali. I-MP2 ifuna i-bitrate engaphezulu kune-MP3 okanye i-AAC yomgangatho ofanayo kwaye ayiziwa kuninzi lweenkqubo zomsebenzisi.

Ingaba ndimele ndigcine iifayile ezintsha njenge MP2?

Ukuba into ephantsi kwendlela ifuna oku. Ifomati iyaqhubeka ivula, kwaye akukho mcimbi wokuguqula uvimba ongazibangela iingxaki, kodwa ayikwazi ukuqhubeka apho isixhobo okanye usebenziso luya khona. Kwanoma iyiphi into entsha, ifomati yangoku ayihlawuli nto engaphezulu kwaye ikhusela umjikelo olandelayo wombuzo kwiminyaka emininzi ezayo.

Ingaba i-MP2 ifayili iyakwazi ukuthwala i-5.1 surround mix?

Ewe - ifomati iphatha ngaphezulu kweendawo ezimbini zesandi ngokuchanekileyo, ngoko ke uthelekiso olujikelezayo lugcina ubeko lwesandi saso kunokuba luyihlole kwi-stereo kwindlela engaphakathi. Ukuba uthetha ngayo njenge-stereo ixhomekeke kwisiphelo eside: umfumani uya kuqokelela zonke iziqhagamshelanisi, ifowuni iya kuhlambulula ngexesha lokudlala ngaphandle kokungakhathali. Ukutshintsha kwifomati ye-stereo kuphela yenza ukuba uthelekiso luhlale.

Ingaba kubaluleke na ukuba u MP2 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-MP2 yi-MPEG-1 Umphezulu Womsindo II, umphezulu ongaphambili kwe-MP3 wavela waba ngumlinganiselo womgangatho womfanekiso we-DVB kunye ne-DAB yosasazo.

Kutheni i-MP2 ifayili ayidlalwanga kwi-browser yam?

Iibrawuzeri zikhupha ikhowudi kuluhlu olufutshane, oluqinileyo lweefomati zesandi kwaye MP2 ingaphandle kwayo, ngoko ifayile ikhupha ezantsi endaweni yokudlala okanye umdlali uxela impazamo. Isoftware yedesktop ene codec ebanzi ivula ngaphandle kwengxaki. Ukuba isandi kufuneka idlala kwiphepha le web, ukuguqula kuyilungisa - akukho mdlali wokumiselwa kwenkqubo uza kudibanisa ikhowudi ekhupha ikhowudi ibrawuzeri ayithuthi.

Yintoni i-bitrate ekufuneka ndiyiguqule iifayile zam MP2?

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. Ukukhowuda ngaphezulu komthombo we bitrate kusezantsi kwesithuba - igcina ngokunyanisekileyo isandi esisele sidlula kwindlela elahlekile kwaye ayibuyiseli nto ikhowudi yokuqala elahlekile.

Ingaba ukutshintshela kutshintsha umyinge wesikhokelo sesandi sam MP2?

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.

Ndingayinika kwakhona igama elipheleleyo lesiqendu endaweni yokuguqula i MP2?

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 MP2 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.
