DESCRIPTION

14       sndfile-generate-chirp generates a sound file containing  a  sine  wave
15       that  sweeps from a low starting frequency to a higher ending frequency
16       (ie a chirp).  The file is written using  libsndfile  (http://www.mega-
17       nerd.com/libsndfile/).
18
19       The parameters allows the start and end sine wave frequencies to be set
20       as well as specifying the shape of the sweep (ie linear,  quadratic  or
21       logarithmic).   Run  "sndfile-generate-chirp  --help" for more informa‐
22       tion.
23
24       The format of the output file is determined by the  filename  extension
25       of the output file.
