       sndfile-generate-chirp  generates  a  sound  file  containing a sine wave that sweeps from a low starting
       frequency  to  a  higher  ending  frequency  (ie  a  chirp).   The  file  is  written  using   libsndfile
       (http://www.mega-nerd.com/libsndfile/).

       The  parameters  allows the start and end sine wave frequencies to be set as well as specifying the shape
       of the sweep (ie linear,  quadratic  or  logarithmic).   Run  "sndfile-generate-chirp  --help"  for  more
       information.

       The format of the output file is determined by the filename extension of the output file.
