       sndfile-generate-chirp [options] <sample rate> <length in seconds> <sound file>

DESCRIPTION

       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.
