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 MP3 audio wapamwamba?
+
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 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 yanga kumatha kusinthidwa?
+
Amachita komwe mtundu wofunikira uli ndi malo omwe angawaike. MP3 amayendetsa ma tag ndi mapangidwe ophatikizidwa ngati gawo la fayilo, ndipo kusintha kwa ma copy a pamalo onse omwe amamvetsetsa. Ma targets opanda malire ndi osiyana - adafotokozedwa pambuyo poti kulemba kwa tag ndi koyenera ndipo samangokhala ndi chilichonse, choncho buku losinthidwa limakhala ngati mchenga wa nyimbo zopanda dzina.
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 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 format iyi nthawi zambiri 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 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.
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.
