How do I convert audio files to mp3?

For website stability, we only allow mp3 formatted audio files to be uploaded.

To convert m4a files, try https://cloudconvert.com/m4a-to-mp3 They have other conversion options for additional audio file types here: https://cloudconvert.com/audio-converter

To convert audio files, try http://nch.com.au/switch. There is a version for Windows and Mac.

We've also been using http://media.io lately with success. 

We don't endorse either of these products.
