MP2 Chosinthira

Chifukwa cha zonse mzere anapangidwa pa izo. Playout ma seva, DVD authoring zipangizo ndi ingest machitidwe anafotokozedwa m'munsimu format pamene izo zinali zatsopano, ndi zida ndi zaka makumi awiri ntchito moyo si anapeza re-anafotokozedwa. Fayilo kutuluka mwa iwo machitidwe ndi format dongosolo anapangidwa kuti emit, si kusankha aliyense anachita posachedwapa. MP2 ndi kwambiri yolimba kuti bit zoipa ndi yosavuta ku decode, amene ndi chifukwa chake kufalitsa masamba anasiya pa izo nthawi yaitali pambuyo MP3 anafika.

MP2 idafotokozedwa m'mawu okha, popanda malo oyenera kwa mutu, album kapena chithunzi chachithunzi, kotero osewera amabwereranso kukuwonetsa dzina la fayilo. Kusintha kwa mtundu wokhala ndi tag ndi zomwe zimapangitsa kuti laibulale ikhale yosakata - ma tag amalemba nthawi yosintha, osati kubwezeretsedwa, kotero yembekezerani kuwonjezera chilichonse chomwe chimachokera. MP2 amafuna kwambiri bitrate kuposa MP3 kapena AAC kwa ubwino wofanana ndi sizikudziwika kwa ambiri wosuta mapulogalamu.

Kupatulapo ngati zinthu zina zimafuna kuti zichotsedwe. Formatiyo imangotsegulidwa, ndipo palibe vuto la kusintha archive yomwe siyikuyambitsa mavuto, koma sikuti ndi komweko kumene ma tool kapena efficiency akuyenda. Kwa chilichonse chokhudzana ndi zinthu zatsopano, formati yatsopano siyimawononga ndalama zowonjezera ndipo imateteza ku mafunso ena a m'tsogolomu zaka zingapo zapitazo.

Yes — format imagwira bwino ntchito ndi ma channels ambiri kuposa awiri, kotero kuti surround mix imasunga ma channels ake ophatikizidwa m’njira yoyenera, osati kuikidwa mu stereo. Kodi mumamva ngati surround kumadalira pa mbali ya mbali: wolandirayo adzachotsa ma channels onse, foni idzalowetsa ma sounds pa nthawi yosewera, ngakhale. Kusintha kwa stereo format imachititsa kuti ma channels azikhala ophatikizidwa m’njira yoyenera.

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. MP2 ndi MPEG-1 Audio Layer II, latsopano la MP3 ndi MP3 ndi mtundu wa audio standard kwa DVB ndi DAB kufalitsa.

Mawebusayiti amachotsa mndandanda wafupi, wokhazikika wa ma audio formats ndi MP2 ndi kunja kwa izo, kotero fayilo imatsitsa pamalo osewera kapena wosewerayo amadziwitsa vuto. Makompyuta a desktop ndi sewero la codec lokulirapo limatsegula popanda vuto. Ngati ma audio amayenera kusewera patsamba la webusaiti, kusinthidwa kwake ndi kusinthidwa - palibe kuwongolera kwa wosewerayo kuwonjezera decoder yomwe msakatuli satumiza.

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.

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.

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.

Mukhozanso kusankha wanu ankafuna kanema mtundu, ndiyeno dinani "Transform" batani. Yanu anasintha kanema adzakhala okhoza kutsitsa mu mphindi zochepa.
