Khalidwe la WMA mtundu ndi ndichiyani?

Anthu ambiri kukumbukira masiku pamene chachikulu pulogalamu kuonera kanema pa kompyuta anali muyezo "Media Player". Magwiridwe, iye sanali kuwala ndipo waubwenzi kwa owerenga wosadziwa sanali amasiyana. Only mu 2000 , Microsoft kwa anthu onse chifukwa Windows Media Player 7 ntchito.

Zinali zosiyana kuchokera kuloŵedwa m'malo osati zapamwamba, koma mfundo ndi kuti anaonekera WMA mtundu analengedwa ndi kampani yokha. Chiyani komanso kumene angathe kugwiritsidwa ntchito? Monga ife tanena kale, izo yapangidwa Microsoft «wozunzikirapo zipinda", pomwe munthawiyo chinali Kenako, ndinazindikira kuti nkhondo wopambana ulendo MP3 iwo sangathe.

Komanso, osewera awo muyezo nthawi kuti adamuthandiza si mokwanira choncho mofulumira anataya kutchuka. Monga "anthu" zina ndi WMA mtundu analengedwa, zimene ife kuyambira anayamba mbedza kapena ndi wakuba, kuti "Kankhani" mu Windows Os. Bwino khalidwe sikunali kokwanira, ndipo si udindo wotsiriza mu izi ankaimba ndale palokha Redmondskoy kampani kasamalidwe.

Yambani ndi chakuti iwo anachita WMA mtundu ndi kampani kwathunthu - anatseka uzigawidwa, kusinthidwa ndi ntchito mankhwala lachitatu chipani. Ndipo ngati awo "ofesi", mchitidwe umenewu anapereka zotsatira zabwino (pambuyo pa zonse, ndi okhawo sichinayambe zimafika), ndiye kulowa msika wa akamagwiritsa matumizidwe ophatikizika amawu, nyimbo ndi zithunzi, ndi kale tikulephera mwa osewera, zinali moona mopusa.

Komabe, makhalidwe a WMA ndi (Windows Media Audio) sali woyipa. Choncho, Mlengi walitenga kuti wothinikizidwa nyimbo file ndi bitrate a 160 kbit / s mawu a khalidwe zosatheka wolephera wapamwamba MP3 kwa nthawi yomweyo mu 256 kbit / s. Maganizo mawu a buku lake loyamba silinachirikize mlingo wapamwamba pang'ono, kupanga WMA mtundu si otchuka kwambiri chilengedwe audiophile. Komanso, pamene phokoso pafupipafupi pamwamba 15 kHz onse "owonjezera" mwankhanza truncated, kotero kuti pafupifupi aliyense "monga CD ina" kukhala.

Tiyenera kupereka msonkho kwa Microsoft: masuku pamutu zinthu zake mbwee, iwo ndi kuthandiza kukhazikitsa ana awo pafupifupi onse "chitsulo" ndi osewera mapulogalamu, kuti lero chilakolako kusintha owona WMA kuti MP3 kwa kubwezeretsa izo wataya kufunika kwake mu player anu. Komanso, kuchokera kutali 1995, pamene Baibulo loyamba codec ake "wokonzekadi" thupi lanyama ake chinayi limene ambiri a zolakwa za nkhani m'mbuyomu chitaikidwa.

Makamaka, khalidwe zogwira kwambiri, n'zotheka ziwiri chikudutsa VBR-kabisidwe, amene basi anamasuliridwa kuti "kosatha aiwala» WMA kuti zimatulutsa osewera mokwanira amphamvu mu msika wa Audio yadigito. Komanso, kwambiri alitcha ndi otchuka Winamp player mungathe "kulanda" mu nyimbo CD ake, imene imafuna yekha pulogalamu yowonjezera out_wma.dll.

Choncho, tinganene kwambiri kutembenuza WMA kwa mtundu MP3 si, chifukwa chifukwa cha kupirira kwa Microsoft codec pa ndime ndi kupikisana akamagwiritsa mothandizidwa ndi zipangizo zonse ndi ma kusewera digito nyimbo. Komanso, chifukwa cha kutembenuka kwa khalidwe phokoso mwina poipa kwambiri, n'zokayikitsa kusangalatsa inu.
