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

Hi!
Take ecanormalize, part of the ecasound package. It normalises files with
intact dynamics. What it actually does is using ecasound functions. First it
analysis the file, by how much can it be amplified without clipping, than it
applies the amplification.
Works weel for me, has done for a long time.
Kindest regards
Julien

If you drag file.wav to its icon, it will create file_normalized.wav,
if you call it on the command line with one argument, it has the same
behaviour. If you call from the command line like so: '0db file.wav
new.wav' it will create new.wav, as you would expect.

The normalize program does that for me.

Summary : A tool for adjusting the volume of wave files
Description :
normalize is an overly complicated tool for adjusting the volume of
wave files to a standard volume level. This is useful for things like
creating mp3 mixes, where different recording levels on different
albums can cause the volume to vary greatly from song to song.
G'luck....

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

normalize-audio noramlizes, no comression/expansion is going on, I use
it all the time. Why was it again this isn't exactly what you want?

Dear Atte,
what command line options do you use to make it normalize a file? As i
understand it, it has a preset dB RMS value of -12. Even if i specify
"-a 1" and -l 0", meaning an absolute amplitude of 1 and a limiter
treshold of 1, i can hear compression. Weird, perhaps i still didn't get it.
regards, Peter
