Hanspeter,

I think this can be done with sox (ports/auido/sox), 

Fragments from a script I have written, not a complete 
solution, just examples to work from:

[snip]
dagrab -v -s -d "${mydrive}" -m 0664 -a 2>/dev/null

   rm mtracks.raw > /dev/null 2>&1

   for xloop in `ls -c1 *.wav`
    do
     sox "${xloop}" -t raw - | cat - >> mtracks.raw
     # sox strips off all header info from wav files so combining is possible
     rm "${xloop}"
   done
                                                                                
   sox -r 44100 -w -s -c 2 mtracks.raw "${mytitle}.wav"
   # sox now writes back from raw file to wav format with header
                                                                                
   rm mtracks.raw

   /usr/bin/clear
   echo "Done with sox, on to bladeenc wav to mp3 encoder"
   sleep 1
                                                                                
   bladeenc -prio=NORMAL "${mytitle}.wav" -delete
   # bladeenc will delete the source wav file after creating the mp3
                                                                                
   mv *.mp3 "${myartist}" > /dev/null 2>&1
