Hi,

   Mqx task use a software decoder to decode the mp3 file which read from SD MFS  one frame by one to PCM data, another task  send these decoded PCM data to  sai driver.

Sai driver send them to TWR-AUDIO-SGTL board's codec sgtl5000,  and it  conversion the pcm data to voice playing it  by headphone.
