Shell does not understand floating point numbers. You'll have to pipe it into bc or awk or some other program/tool/language which does.
There are a lot of syntax errors in your code, also. You can't do X = value you have to do X=value Also there is no INT( ) function in bash. Besides which, functions don't even work that way in bash.
Thank you for the reply. I want to know what is the total number like 1,144,750,000,000,000. I do not know what the right value.. but some thing like that.

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.
