Ngaphezu kwalokho, abadlali babo ejwayelekile ngaleso sikhathi okwamsekela hhayi ngokwanele kakhulu nokuduma Ngakho ngokushesha walahlekelwa. Njengoba format a "abantu" okunye futhi WMA yadalwa, esiye kusukela iqaliswe hook noma nge kwengobe, ukuze "push" ku-OS-Windows. Impumelelo umkhuba onjalo kwakunganele, hhayi indima wokugcina kule kudlalwa ezombusazwe ngokwayo ukuphathwa inkampani Redmondskoy.

Qala nge yokuthi benza WMA Ifomethi nokuphathelene ngokuphelele - valiwe zokusabalalisa, ukuguqulwa kanye nokusetshenziswa imikhiqizo third-party. Futhi uma "ihhovisi" yabo, lo mkhuba satlikitlwa omuhle (phela, okunguye yedwa engakaze kukhanselwe), bese ufaka emakethe takhiwo multimedia, futhi kakade Kwakugcwele abadlali, kwaba ngokungagwegwesi silly.

Nokho, izici WMA (Windows Media lomsindo) kubi kangaka cha. Ngakho, umenzi lithi ecindezeleke umculo ifayela nge-bitrate lalokhu 160 kbit / s ngokuya izinga neze kunabayeni ifayela MP3 nenani lesikhathi esifanayo ngo-256 kbit / s. isitatimende impikiswano, futhi version yayo yokuqala akazange ayisekele eliphakeme bit, okwenza ifomethi WMA ingajwayelekile kakhulu imvelo audiophile. Ngaphezu kwalokho, lapho imvamisa umsindo ngenhla 15 kHz zonke "extra" okwalapha incishisiwe, ukuze mayelana nanoma yisiphi "njengoba i-CD" ayikwazanga kubhekwe.

Kumele sikhokhe intela Microsoft: sibambe nemithombo yawo cishe angenamkhawulo, banayo ukusekela ukuqaliswa nenzalo yabo cishe zonke 'nensimbi' nabadlali isofthiwe simo, kangangokuba namuhla isifiso ukushintsha amafayela WMA MP3 ukuze kudlalwe ke ilahlekelwe ngokuhlathulula ukusebenza kwawo e zesidlali sakho.
