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.
This is probably not the best way to do it, but it's worked for me:
for i in `ls *wav`; do
FOO=`sox $i -e stat -v 2>&1`
BN=`basename $i .wav`
echo "norming $i with factor $FOO ..."
sox -v $FOO $i -t wav ${BN}.norm.wav
done
