envext

ENVEXT(1)						  The Canonical Csound Reference						 ENVEXT(1)

NAME

       envext - Extracts the envelope of a file to a text file. .

SYNTAX

	   envext [-flags] soundfile

	   csound -U envext [-flags] soundfile

INITIALIZATION

       soundfile - Name of the input soundfile.

       The following flags are available for envext (The default values are stated in parenthesis):
	   -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:

	     0.000   0.000
	     0.000   0.000
	     0.250   0.000
	     0.500   0.000
	     0.750   0.000
	     1.249   0.170
	     1.499   0.269
	     1.530   0.307
	     1.872   0.263
	     2.056   0.304
	     2.294   0.241
	     2.570   0.216
	     2.761   0.178
	     3.077   0.011
	     3.251   0.001
	     3.500   0.000

       Which shows the time for the peak amplitude within each measured window.
