Benjamin,
Don't know if this helps you or not, but this is taken right from
Jtodd's wiki page.
**my disclaimer** Might want to backup your sounds before doing this though.
#!/bin/sh
tmpfile=/tmp/rescale$$.wav
for i in *.wav; do
scale=$(sox $i /tmp/foo.wav stat -v 2>&1)
if [ $scale != "1.000" ]; then
echo -n "Rescale $i..."
cp $i $tmpfile
sox $tmpfile -v $scale $i
echo
fi
done
The wiki page is at
http://www.voip-info.org/tiki-index.php?page=Asterisk%20sound%20files
Hope this helps,
-Chuji
