Hi Serban, 
     
    thanks a lot. 
    It's clear now, what I'll do tomorrow .-). 
     
     
    Best,

    Apparently, there are
        a few options, from
        Java wrappers to the FFTW to native Java implementations of
        FFTW: 
       
      http://www.fftw.org/download.html-> they mention 2 choices here, in
        sections "Calling FFTW from
        Other Languages" 
       
      https://sites.google.com/site/piotrwendykier/software/jtransforms-> this is a native implementation
        of FFT in Java that is already used
        by a few projects. (maybe your best bet) 
       
      http://carsomyr.github.io/shared/-> this is a more diversified
        scientific package, but it mentions that
        it provides multidimensional FFT operations backed by FFTW3. 
       
      Hope this helps.

      Does anyone can recommend a good java-based
          fast fourier
          transformation  
          (FFT) library?
