Re: normalizing mp3s under debian/linux
ok, thanks a lot to you all.
Here´s what I did:
find . -regex ".*\ .*" -exec kickspaces.sh {} \;
---kickspaces.sh---
#!/bin/bash
OLD=$1
NEW=`echo $OLD | sed s/"\ "/"_"/g`
mv -v -i "$OLD" $NEW
------
to kick all of the spaces in the files (I always intended to do so
sometimes and now was the "some"time ;-) )
I`m now making another backup of all my mp3´s and then will run
---anpass.sh---
#!/bin/bash
for MP3FILE in `find . -name '*.mp3'`; do
FILE=`echo $MP3FILE | sed s/"\.mp3$"//`
echo "converting: $FILE to WAV"
/usr/bin/nice /usr/bin/mpg123 -w $FILE.wav $MP3FILE
echo "...done"
echo "normalizing $FILE."
/usr/bin/nice /usr/bin/normalize -a 0.25 -n -v $FILE.wav
echo "..done"
mv $MP3FILE $MP3FILE.bak
/usr/bin/nice /usr/bin/gogo -v 9 -b 128 $FILE.wav
echo "**********************"
echo " "
done
------
When I´m done with some test-files I´m coming back and´ll tell you how
the quality suffered ;-) (and will proceeed accordingly or restore from
backup ;-) ).
And to the point of loosing information when fiddling with the volume:
I usually copy randmon mp3s to my rio and it´s _absolutely_ annoying to
have to adjust the volume for each&every song...on the other hand, most
of it´s rock & heavy metal so it a little quality loss doesn´t really
matter at all.
again: tnx!
&rw
