WMA Zida

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. WMA ndi Windows Media Audio, yankho Microsoft MP3, anayamba mu 1999 ndi anasonkhana ndi aliyense Windows kukhazikitsa wa nthawi imeneyi.

Amachita komwe mtundu wofunikira uli ndi malo omwe angawaike. WMA 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 chiwopsezo - adafotokozedwa pambuyo poti tagging ndi chiyembekezo choyenera ndipo samangokhala ndi chilichonse, choncho buku losinthidwa ndi njira yofika ngati mchenga wa nyimbo zosadziwika.

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. WMA ndi unsupported pafupifupi kulikonse kunja kwa Windows, ndi zaka WMA owona angagwiritsidwe ntchito DRM kuti amaletsa kusintha kwathunthu.

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.

Mawebusayiti amachotsa mndandanda wafupi, wokhazikika wa ma audio formats ndi WMA 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.

Popeza chomeracho ndi chimodzi mwazinthu zothandiza. WMA idafotokozedwa m'ma codecs a Microsoft, ndipo palibe chilichonse chomwe chimachokera ku Windows chomwe chimatumiza decoder kwa iwo - choncho fayilo imatsegulidwa, imadziwitsa nthawi yake, ndipo imapanga chithunzi kapena mawu onse. Kukhazikitsa codec pack ndi yankho lakale komanso lolimba; kusinthira payload kukhala chinthu chomwe chilichonse cha platform chimasintha ndicho cholimba. WMA ndi lossy mwa default, mu ASF chidebe, ndi lossless ndi mawu-optimised mitundu yomwe ndi yosadziwika anakumana.

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.

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.

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