With the command below ffmpeg will probably try to encode *all*
files in a folder ... careful ... :)

Batch mode encoding all sorts of video and audio files in a folder, no
matter what sort (avi, wav, mp4, wav, au etc. ) to  mp3, with a single
command:

for f in *.*; do ffmpeg -i "$f" -codec:a libmp3lame -qscale:a 0 
"${f/%.*/.mp3}"; done

Caveats, notes: 
Tests were done in zsh and bash (system shell seems bash; zsh was
entered  with a simple 'zsh' at a bash prompt)

If input file names are identical before the suffixes (like
example.avi and example.wav) ffmpeg, while encoding, will ask whether to
overwrite the first example.mp3 it made. Should be doable by simply
renaming these input files ... or by writing better code than I
did .. ;)

I haven't done tests with input files with spaces in their names ...
so: careful!

I only do scripting casually; i.e. when I need it. I'm not a pro in
that. So if someone knows how to optimize the snippet: welcome ... ;)

Thanks to everyone in this thread. It helped lots. ... ;)

You can also use "${f/%m4a/mp3}" in bash and zsh (and
possibly other shells, but I'm not familiar with pattern
substitution in others).  The % at the beginning of the
pattern achors the match to the end of the string.

(Not that it's important; I just like playing shell golf. :)

ffmpeg uses libmp3lame to convert from ma4 to mp3.  So, install lame-libs.  And 
you'd

I certainly would try ffmpeg, the Swiss Army knife for
audio/video ... :)

ffmpeg -i input.m4a output.mp3
and see what happens ...

or:
ffmpeg -i input.m4a -codec:a libmp3lame -qscale:a 0 output.mp3

Several things possibly.

* Soundconverter features automatic detection of needed GStreamer
plugins and automatic installation of the needed packages. In case
you've not seen a graphical dialog about that, it may be broken,
and manually installing missing gstreamer-plugins* packages from
3rd party repositories may be needed. Explicitly note that the new
gstreamer1-* packages are not compatible.

* What happens if you try to decode an .m4a file to .wav? If that
fails already, you are missing a plugin package.

* Perhaps install a different conversion tool, such as
"audio-convert-mod". It is not based on GStreamer, but is a
graphical frontend that uses command-line tools as backend.
It tells which converters are available, so you get a good overview.

One can use vlc to convert between various formats. just for fun i
converted a m4a to a mp4. Not sure if it'll go to mp3 or not.

also, the man page for ffmpeg documents some commandline examples that
will convert various formats to m4a. does this mean it 'll also]
convert FROM m4a? I don't know. but you may want to try it, it is 
an amazingly versatile tool!
