[Plextalk] Want to record music from my computer to my Plextalk and change the file from a daisy file to an mp3 file

Hi. I would like to record music from my computer to my ptp1 Plextalk player. After I record the album from my computer to my Plextalk can I change that file from a daisy file to an mp3 file? If I can do this, how do I go about changing the file from a daisy file to an mp3 file? Thanks allot and have a good day.
