Chokhacho chomwe encoder yakale idaganiza zochotsa, ndipo sichingathe kubwezeretsedwanso. MP3 imatulutsa popanga zomwe nkhope sizingawone - zowoneka bwino zokhala pansi pa zowoneka bwino, ma frequencies pa maziko a kumvetsera - ndi kuzichotsa mwamsanga. Pa bitrate yolimba yomwe siyimadziwika kwa anthu ambiri. Zimene sizosinthika, chifukwa chake kusinthidwa ku mtundu wopanda kusowa kumateteza dziko latsopano kuposa kubwezeretsa mtundu woyamba. MP3 ndi lossy: psychoacoustic model amachotsa ma frequencies kuti nkhope sizingayembekezere kuti adziwe, makamaka pa 128 mpaka 320 kbps.
N'chifukwa chiyani CD rippers amasinthidwa kuti MP3?

Chifukwa cha izi, mfundo zoyambirira za nyimbo zinali zogwirizana ndi zida zomwe anthu anali nazo, ndipo zoyambirira zimasungidwa nthawi yaitali pambuyo pa kulephera. Buku la nyimbo limeneli linali losankhidwa zaka zambiri zapitazo, osati chifukwa cha lamulo la nyimbo. Kubwezeretsa nyimbo kuchokera pa diski kumapatsa katswiri wabwino; kusinthira zomwe muli nazo sikunatheke, chifukwa mfundo zoyambirira za nyimbo zomwe zidachotsedwa sizikupezeka mu fayilo yobwezeretsedwa.

Pamene iwo sachita, kuti ndi chifukwa chosintha.
Kodi MP3 idzasewera mobwerezabwereza patsamba la webusaiti?
+
Ndikukhulupirira. MP3 ndi imodzi mwamaudindo a audio omwe amagwiritsa ntchito masamba, motero amatha kutulutsidwa m'mawu a audio kapena wosewera podcast ndipo amagwira ntchito zonse popanda plugin kapena fayilo ya fallback. Izi zimapangitsa kuti zikhale zotetezeka zofalitsa, ndipo chifukwa chake kusinthira kujambula kwa exotic ku mtunduwu ndi nthawi zambiri 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 ku theka. Kulemba mawu kudzera pa ma bitrate ochokera kumawononga malo - amasunga mawu omwe kale apita ku 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 a m'machitidwe a m'machitidwe a m'machitidwe a m'machitidwe a m'machitidwe a m'machitidwe a m'machitidwe a m'machitidwe a m'machitidwe a m'machitidwe a m'machitidwe a m'machitidwe a m'machitidwe a m'machitidwe a m'machitidwe a m'machitidwe a m'machitidwe a m'machitidwe a m'machitidwe a m'machitidwe a m'machitidwe a m'machitidwe a m'machitidwe a m'machitidwe a m'machitidwe a m'machitidwe a m'machitidwe a m'machitidwe a m'machitidwe a m'machitidwe a m'machitidwe a m'machitidwe a m'machitidwe a m'machitidwe a m'machitidwe a m'machitidwe a m'machitidwe a m'machitidwe a m'machitidwe a m'machitidwe a m'machitidwe a m'machitidwe a m'machitidwe a m'machitidwe a m'machitidwe a m'machitidwe a m'machitidwe a m'machitidwe a m'machitidwe a m'machitidwe a m'machitidwe a m'machitidwe a m'machitidwe a m'machitidwe a m'machitidwe a m'machitidwe a m'machitidwe a m'machitidwe a m'machitidwe a m'machitidwe a m'machitidwe a m'machitidwe a m'machitidwe a m'machitidwe a m'machitidwe a m'machitidwe a m'machitidwe a m'machitidwe a m'machitidwe a m'machitidwe a m'machitidwe a m'machitidwe a m'machitidwe

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 ndingasinthe fayilo yonse ya MP3 mafayilo m'modzimmodzi?
+
Ndi akaunti, yeah - kugwa iwo limodzi ndipo iwo ali mu mnda monga ntchito imodzi kuposa kusamalira mmodzi pa nthawi, ndi zosankha zofanana zogwiritsira ntchito m'magulu ndi zotsatira zobwerera limodzi. Free conversions kuyendetsa imodzi wapamwamba pa nthawi (kuphatikiza zida zimatenga awiri); a ndalama malire ndi zimene zimatsegula processing gulu ndi zikuluzikulu per-fayilo malire, amene ndi zimene amachititsa kusintha archive lonse zothandiza.
Kodi chimachitika chiyani kwa fayilo yanga ya MP3 pambuyo posintha?
+
Idzathetsedwa. Kutsitsa ndi zotsatira zosinthidwa zimasungidwa pa seva nthawi yomwe ntchitoyi imafunikira ndipo zimathetsedwa mwamsanga; kutumiza kumachitika pa HTTPS m'njira ziwirizi. Palibe amene amawerenga zomwe zilimo, palibe chomwe chimaphatikizidwa mu index, ndipo palibe chomwe chimapita kwa wina aliyense. Ngati simukufuna kuyembekezera kuchotsa kwachidule, kutseka ntchitoyo kumachotsa mafayilo mwamsanga.
