Hello,
Depending on the audio software you are using to record your podcast files, you can either choose to save your files in the .mp3 format, or use additional software to convert the completed audio files from their original format into the .mp3 format.
You can use your favorite search engine to search for more information by entering 'convert audio to .mp3 format.'
We recommend the 'Audacity' software -- it's free to download and use, and allows the conversion of most audio file types into the .mp3 format. Here's a link for more information:

Thank you,
Mike
