       sndfile-spectrogram [options] <sound file> <img width> <img height> <png name>

DESCRIPTION

       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.
