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

MP3 ndi mtundu wa audio wopanda kusowa. Wolemba mawu amachotsa ma frequencies osamvetseka ndi mawu opanda kusowa kuti afike pa kukula kwa fayilo kofanana ndi theka la mtundu wopanda kusowa. Kulembanso mawu kwa MP3 ku mtundu wina wopanda kusowa kumabweretsa kuwonongeka kwa mtundu; kusintha kuchokera ku master yopanda kusowa pamene kuli kotheka.

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.
Chifukwa chake ali ndi zonse zokhudzana ndi diski popanda kuwononga chilichonse cha izo - chilichonse cha mawu, chilichonse cha subtitle, mnda wazaka - mu fayilo imodzi. Izi ndi zosasinthika zoyenera pamene cholinga ndi kuika uthenga wa oyambirira, ndipo zosayenera pamene fayilo iyenera kusewera pa chipangizo chomwe chimamvetsa mtundu wotumizira. Sichoncho beats MP3 kwa kugwirizana - car stereos, gym zida, DAPs ndi zaka makumi awiri hardware onse kuwerenga izo popanda funso.
Kodi woimba, album ndi kusindikiza kwa MP3 anga adzakhala ndi kusintha?

Amachita zomwe mtundu wofunikira uli ndi malo omwe angawaike. MP3 amayendetsa ma tag ndi mapangidwe ophatikizidwa ngati gawo la fayilo, ndipo kusintha kumakopa pamalo onse omwe amamvetsetsa. Ma targets opanda kulumikizana ndi chiwopsezo - adafotokozedwa pambuyo polemba kuti kulemba kwachikhalidwe ndi kuyembekezera koyenera ndipo samangokhala ndi chilichonse, kotero buku losinthidwa ndi njirayi limafika ngati mchenga wa nyimbo zopanda dzina.
Kodi ndi chinthu chofunika kuti MP3 ali 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 zimene 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 webusaitiyi?

Ndikukhulupirira. MP3 ndi imodzi mwamaudindo a audio omwe mabrowser amagwiritsa ntchito, motero amatha kutulutsidwa m'mawu a audio kapena wosewera podcast ndipo amagwira ntchito kumapeto kwa mafoni popanda plugin kapena fayilo ya fallback. Izi zimapangitsa kuti zikhale zotetezeka zofalitsa, ndipo chifukwa chake kusinthira kujambula kwa exotic ku mtunduwu ndi njira yofupikitsa kuti ikhale yosewera patsamba.
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
Ndi MP3 lossy kapena lossless?

MP3 ndi lossy - encoder amachotsa deta encoder akatswiri kuti ndi inaudible kuti afike m'lifupi wapamwamba kukula. MP3 ndi mwaukadaulo outclassed ndi AAC ndi Opus pa zonse bitrate, sangathe kusungira zambiri kuposa awiri ma channels bwino, ndi nthawi zonse amawonjezera m'badwo wa encoder.
