WMA haitsigirwe zvakakwana chero kupi kunze Windows, uye vadiki WMA mafaera anogona kutakura DRM kuti anobata kushandura zvakakwana.

Nei mutauro wemutauro unonzwa sewevakadzi munguva iyi?

Nekuti imwe nzvimbo yacho inonzi codec yechitaura kupfuura codec yechirongwa chemuvhi. Inoratidza pfungwa dzevanhu uye inobvisa zvese zviri kunze kwebandwidth yefoni, izvo zvinokosha kana uchida kutumira meseji uye zvinokuvadza kana uchida kutumira chero chinhu chine mainstruments. Kuchinjana kwacho hakugone kudzosera mafrequencies akaipa — havana kunyorwa mukodzero yekutanga.

Ndeipi bitrate iyo iyo AMR faira ichashandisa?
