I'm working at a radio station now, and the only format it plays is mp3 (sucks). Is there any way i can convert my m4a and wmp files to mp3? What are the pros and cons? And if the cons are too much, is there any way I can upgrade the radio program to play m4a's?

What kind of radio station only plays mp3s?

A radio station in the Dominican Republic...

i want to know how to convert m4a files to mp3 as well
