I often use sound converter to convert my audio files to mp3 and It works perfectly on Ubuntu Unity but when I move to Ubuntu Gnome there is no option for mp3 format.

Sound converter does show how to install a codec to enable the function but the codec has been already installed on my computer.

How can I enable mp3 coverting, or is there any other software that works?

It might be late, but still for others who are still looking to encode into mp3 using Sound Converter, install gstreamer0.10-plugins-ugly .


I found my solution in the comments here.

Reproduced below:

To enable conversion from mp4 to mp3 in ubuntu 16, I had to do sudo apt-get install ubuntu-restricted-extras - @wordsforthewise


sudo apt-get install ubuntu-restricted-extras

And close and open SoundConverter. :)


Works on Ubuntu 16.04 LTS.


The MP3 codec isn't installed by default by Ubuntu but can easily be added by searching for gstreamer0.10-fluendo-mp3 in the software centre or using synaptic...

  • gstreamer0.10-fluendo-mp3 is already installed. Still can't convert audio files to mp3. Jul 29, 2013 at 13:31
