Indeed with MP3s this is not so easy.  It is probably simply impossible to do 
so after encoding, even when re-packing the MP3 files (i.e. not using file 
concatenation, but copying data selectively, using the bit reservoir and what 
else there is), due to the fundamental nature of the encoding (being 
frequency- and not time sampling-based).

So in your case I would agree with Aleksandar, that .wav concatenation is the 
way to go.

Best,
  Hans
