       sndfile-spectrogram  reads  a single channel sound file and generates a spectrogram which is written to a
       PNG file with specified image height and width.

       The optional parameters allow the user to specify the dynamic range of the  spectrogram  plot  and/or  to
       disable  the  drawing  of borders, scales, heat map and title.  Run "sndfile-spectrogram --help" for more
       information.

       The input file is  read  using  libsndfile  (http://www.mega-nerd.com/libsndfile/),  the  spectrogram  is
       calculated  with the help of libfftw and the spectrogram is rendered and written to the output file using
       libcairo.
