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.
