[LAU] Normalize from command line?

[Peter Plessas]

Dear List,

does anyone know of an application (or script) to normalize audio-files 
from the command line? I have only come across "normalize-audio" which 
does compression across multiple files, but i haven't figured out how to 
raise the amplitude of a file to +/-1 without altering it's dynamics. I 
am sure this could be done using a two-pass sox script, but before i 
start writing my own, i wanted to know if a similar solution already exists.

Thanks for any hints,

Peter
