draw_spectrum_from_selection.praat

# This script will draw a spectrum from a 40 ms window around the cursor in the editor window.
#
# The original version of the script can be found in the scripting tutorial of the built-in Praat manual.
# However, the original script does not work with the new Praat versions; this one does. :-)
