I was about to fire off a similar email, but Chris beat me to the 
punch.  If you just want the volume adjustment, you can add "-v" 
at the end of the command:

   sox my_file.wav -n stat -v

and all it reports is the volume number with no extra 
information.  Can be useful for scripting purposes too.
