	   -o fnam Name of output filename (newenv)
	   -w size (in seconds) of analysis window (0.25)

       The envext utility generates a text file containing time and amplitude pairs by finding the absolute peak within each window.

EXAMPLE

       Using the command (while in the manual directory):

	   csound -U envext examples/mary.wav

       will produce the a text file containing the following:
