could you improve your answer so as to provide commands for converting multiple files of the same type or of different types? (i mean something like ffmpeg -i *.ra *.mp3) – cipricus Oct 22 '12 at 14:44
I think this program only take one file as input, but you can always make a script to run it for multiple files. For example: for i in *.ra; do ffmpeg -i $i $(echo $i | sed 's/\.ra/\.mp3/'); done – Eirriel Oct 22 '12 at 15:43
is there a gui for this? it seems much faster than soundconverter? – cipricus Oct 22 '12 at 18:38
i don't know soundconverter but ffmpeg is a command line utility. maybe there is some 3rd party frontend – Eirriel Oct 22 '12 at 19:05

In this case I had to use a piece of heavy artillery I was familiar with in Windows: Format Factory (for a clean download use the torrent)

Unzip if needed and install Format Factory ... after installing Wine, of course.

A lot of settings are possible

You can use sound converter. open up your terminal and type this to install . sudo apt-get install soundconverter

it is an advantage in using a gui for ubuntu: but isn't it a bit slow? it took a lot of more time than the other solutions – cipricus Oct 22 '12 at 18:33
