Mafayilo a MP3 amagwiritsa ntchito kukanikiza kosafunikira kuti achepetse kukula kwa fayilo pamene akusunga mtundu wabwino wa mawu kwa omvera ambiri.
Ntchito Zofala
Kusunga ndi kusewera nyimbo pazida zonyamulika
Kugawa ma podcasts ndi mabuku omvetsera
Kutumiza mawu pa intaneti
MP3 Mafunso Ofunsidwa Kawirikawiri Okhudza Kusintha kwa Anthu
Kodi ndi fayilo ya MP3?

MP3 (MPEG Audio Layer III) ndi mtundu wa digito wa ma code a audio womwe umagwiritsa ntchito kupsinjika kwa deta yotayika.
Kodi kuchuluka kwabwino kwatha kuwonongeka m'fayilo ya MP3?
+
MP3 compresses ndi modeling zimene nkhope sadzaona - chisoni maganizo ozungulira pansi olimba, ma frequencies pa malire a kumvetsera - ndi mwamsanga kuchotsa izo. Pa bitrate bwino kuti ndi inaudible kwa pafupifupi aliyense. zimene sizosatheka ndi reversible, kotero kusintha kuti lossless mtundu amateteza dziko latsopano kuposa kubwezeretsa oyambirira. MP3 ndi lossy: psychoacoustic model amachotsa ma frequencies kuti nkhope sizingayembekezere kuti adziwe, makamaka pa 128 mpaka 320 kbps.
Kodi ndi vuto kuti MP3 ili ndi zaka zoposa makumi atatu?
+
Age yekha si vuto - angapo mtundu kuchokera kuti nthawi ndibe bwino, makamaka chifukwa chilichonse chili ndi zaka kuti akwaniritse iwo. Zimene zikukhudza ndi zimene nthawi anaganiza: mavidiyo ang'onoang'ono, mofulumira processors, palibe netiweki, ndi zizindikiro aliyense anafunikabe. Pamene amene anaganizabebe, mtundu ndi bwino. Pamene iwo sachita, kuti ndi chifukwa chosintha. MP3 ndi MPEG-1 Audio Layer III, anamaliza mu 1993, ndibe kwambiri universally decodable audio mtundu kuti ali.
Kodi MP3 idzasewera mobwerezabwereza patsamba la webusaiti?
+
Ndikukhulupirira. MP3 ndi imodzi mwamaudindo a audio omwe amagwiritsa ntchito masamba, motero amatha kuikidwa mu audio element kapena podcast player ndipo amagwira ntchito zonse popanda plugin kapena fayilo ya fallback. Izi zimapangitsa kuti zikhale zotetezeka zofalitsa, ndipo chifukwa chake kusinthira kujambula kwa exotic ku format iyi nthawi zambiri ndi njira yofupikitsa kuti ikhale yosewera patsamba. Sichoncho beats MP3 kwa kugwirizana - car stereos, gym zida, DAPs ndi zaka makumi awiri hardware onse kuwerenga izo popanda funso.
Kodi ndiyenera kusintha bwanji mafayilo anga a MP3?
+
Kugwirizana ndi malo osankhidwa, si cholinga. Kwa nyimbo, 256 mpaka 320 kbps ndi zosaoneka kwa aliyense womvetsera; kwa mawu ndi podcasts, 96 mpaka 128 kbps ndi zambiri ndipo amadula fayilo yachiwiri. Kulemba mawu kudzera pa ma bitrate ochokera kumawononga malo - amasunga mawu omwe kale apita kudzera pa lossy pass ndipo sabwezeretsa chilichonse chomwe chimatulutsidwa ndi wolemba mawu woyamba.
Kodi kusintha kumasintha kuchuluka kwa sampling ya MP3 audio yanga?
+
Sichoncho ngati simukupempha kuti ichite zimenezi. Kusintha kumasunga mitengo ya machitidwe a m'mawu ochokera - 48 kHz imakhala 48 kHz, 44.1 kHz imakhala 44.1 kHz - chifukwa kubwezeretsa machitidwe a m'machitidwe ndi mtengo wotsika wabwino wopanda phindu pamene palibe chomwe chimafuna kuti. Zosagwirizana ndi izi ndi zachidziwikire: ma CD a nyimbo amafuna 44.1 kHz, ena mwa osewera a hardware oyambirira amavomereza chilichonse chokhudzana ndi izi, ndipo ma pipelines a mawu nthawi zambiri amafuna 16 kHz. Sankhani mitengo yokhayokha m'machitidwe amenewa ndipo musiya izi zipite.
Kodi ndingasinthe dzina la chidacho popeza MP3 sichisintha?
+
Kwambiri nthawi zonse, ndipo ndi bwino kumvetsa chifukwa chake: kuwonjezeka ndi label, pamene bytes m'maganizo ndi zopangidwa kwa mtundu wina mfundo. Kusintha dzina amapanga fayilo amene dzina lake amalonjeza chinachake za zinthu zake sikuti kubweretsa, ndi zimene amatsegula izo kapena amakana fayilo kapena misreads izo. Mmodzi waukulu kulephera ndi awiri mtundu amene ndi weniweni wofanana wonyamula pansi pa dzina losiyana - ndi ngakhale pamenepo bwino rewrap ndi chitetezo kuposa kusintha dzina.
Kodi chimachitika chiyani kwa fayilo yanga ya MP3 pambuyo posintha?
+
Kutsitsa ndi zotsatira zosinthidwa zimakhazikika pa server yathu kwa maola 24, zomwe zimasiya nthawi yotsitsa zotsatira, ndipo zimatulutsidwa ndi kuchotsa kwaotomatiki. Kusinthanitsa kumachitika pa HTTPS m'mitundu yonse. Palibe amene amawerenga zomwe zili, palibe chomwe chimawerengedwa, ndipo palibe chomwe chimapita kwa wina aliyense.
