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 -- / Ing.
