Hi,
when i navigate to the folder with the source file and manually execute the following command it works:
sox threebursts.wav temp_outfile.wav silence 1 0.1 1 : newfile : restart

but if I craete a batch file which takes teh file as argument, it doent work:
sox "%~1" temp_outfile.wav silence 1 0.1 1% 1 0.1 1% : newfile : restart

it results into :
>sox "C:\Users\hom\Downloads\Desktop\New folder (3)\threebursts.wav" temp_outfile.wav silence 1 0.1 1 : newfile : restart

Any idea why that do not work please?

Cheers H

A % sign has special meaning in bat files.  Look - you used "%~1" - and 
expected that
to be replaced by a parameter.  Well, further along the command the 
other % chars
caused a problem.

You need to use %% where you want a single one.  See: "Quoting and 
escaping" at:

Yeah I know and the manual says :
"
The command-line arguments AKA command-line parameters passed to a batch script are accessible as %1, %2, ..., %9.
"
as well as "%~1" search the doc ...

When dragging a file on the the bat file , the %~1 with be replaced with the path to the file as mentioned in my first post. But that wasnt the question. It works , try it.

So "%~1" becomes  "C:\Users\hom\Downloads\Desktop\New folder (3)\threebursts.wav"

The question is now wht is this command not working:

sox "C:\Users\hom\Downloads\Desktop\New folder (3)\threebursts.wav" temp_outfile.wav silence 1 0.1 1 : newfile : restart

No, but the "&" signs further along your command might be the problem.  
In your
original question you described a command containing

  sox "%~1" temp_outfile.wav silence 1 0.1 1% 1 0.1 1% : newfile : 
restart

Note the: "1 0.1 1% 1 0.1 1% "

I am not sure whether your command really contained all of that or had 
the
simpler "1 0.1 1" parameters in it.

I was trying to say that if you'd wanted  "1 0.1 1% 1 0.1 1%"  to work 
you
would have needed to code  "1 0.1 1%% 1 0.1 1%%", for the BAT file to 
use
the command you wanted.

If that's not what you were asking, you need to be clearer.

OK, so that's a different question.   "Not working" is not a useful
description of what is or is not happening.

What is in threebursts.wav?

What does happen?  How many files are produced, if any?

What did you expect/hope would happen?

Does the expected single action work properly if you omit the newfile
& restart?
