The audio file that you upload must be in a specific format so that it can be played from within your website. The file must be an MP3 audio file with a bitrate between 32kbps and 160kbps and a sample rate of 44100 or 22050.

We recommend that you use Audacity to convert your audio files to the correct MP3 format. It's both free and easy to use, don't you just love Open Source software?

Of course, you can also use expensive audio programs like Peak for MacOS or Soundforge for Windows to create this type of MP3 file.
