Hi.
Just to let you know, we record voices with audacity, and export audio as
flac, just in case we need to edit it.
Then I have the following sh script:
o# cat convert.sh
#!/bin/sh
today=$(date +%F);
mkdir -p $today/flac;
mkdir -p $today/wav;
mkdir -p $today/ul;
for i in *.flac;
do
echo "------------"
echo "Processing $i";
echo "------------"
#$filename=
sox $i -r 8000 -c 1 $(echo $i|rev|cut -d "." -f2-10|rev).wav;
normalize-audio -a 25dB $(echo $i|rev|cut -d "." -f2-10|rev).wav;
mv $i $today/flac/;
sox $(echo $i|cut -d "." -f1).wav $(echo $i|rev|cut -d "."
-f2-10|rev).ul;
mv $(echo $i|rev|cut -d "." -f2-10|rev).wav $today/wav/;
mv $(echo $i|rev|cut -d "." -f2-10|rev).ul $today/ul/;
echo "";
done
echo "All done";
