MP3 Imibuzo Ebuzwa Rhoqo Ngokuguqula

Yintoni ifayili MP3?

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 engayikuva ngaphaya kwabanye 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.

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.

Yintoni i-bitrate ekufuneka ndiyiguqule iifayile zam MP3?

Uthelekiso lwendawo ebekwe kuyo, hayi umthombo. Kwingoma, 256 ukuya 320 kbps icacile kuye wonke umntu ophulaphulayo; kwilizwi kunye nepodcasts, 96 ukuya 128 kbps ininzi kwaye iqulethe ifayile kwakhona. Ukunxulumana ngaphezulu komthombo we bitrate kusezantsi kwesicwangciso - 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 lunye, kwaye imibhobho yelizwi ifuna 16 kHz. Cwangcisa umyinge ngokucacileyo kwezi meko kwaye uyishiye ngaphandle.

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.

Uthutho luya kuhamba ngaphezulu kwe HTTPS kumgca omnye nolunye. Akukho mntu ufunda okuqulethekayo, akukho nto ibhalwe kwisikhokelo, akukho nto igqityiwe komnye umntu.

Ngaba ukucutshungulwa kweevidiyo simahla??

Ewe, i-converter yethu isimahla ngokupheleleyo ukuze isetyenziswe ngokulula. Akukho bhaliso lufunekayo.

Ngaba umgangatho wefayile yam uza kugcinwa ngexesha lokuguqulwa?

Oku kuxhomekeke kwifomati. Isiphelo esingalahlekiyo njenge-PNG, WAV okanye FLAC sigcina okunomthombo; isiphelo esilahlekiyo njenge-JPG, MP3 okanye MP4 sihlala siphinde sikhowudiwe, esitshintshiselana ngeenkcukacha ngefayile encinci.
