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).

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