How do I convert my audio recording on Galaxy S6?

[cmontero]

I used audio recorder on Galaxy S6 and tried emailing it via Gmail but nobody could hear it? How do I change it from m4a to mp3? It won't let me send it via text or Facebook either. Help??

First, the receiving party might have to download the same audio recording app you have or one of the following apps, VLC for Android or MX Player

Next I would find a different audio recorder that saves it's files as a mp3.
