My mp3 export does not contain sound.

Hi, i recorded some music with Audacity and i exported the file to mp3. However, the mp3 does not contain any sound.
Thanks.

Open the MP3 in Audacity. Do you have blue waves, or a flat line?

There are ways to make a show which only has sound on some players but not all. Do you have waves?
