Itunes to mp3 or ogg or whatever

I wanted to convert my Itunes collection from my old mac to work on my FC10 box. I have posted here because this script does not quite work.
I have taken two other scripts from some this and other unix forums and almost made a recursive converter from what I saw in those.

At the moment the script sits at the root of the Music folder and when called by name it recursively works through the folder and converts the files at the end of the tree. (Currenlty it deletes intermediate files but not the original m4a files). It almost works(:-()

It would be more elegant to have a file in /usr/bin called m4a2mp3 or m4a2ogg which you gave a couple of parameters to and it then did its stuff.

Any takers?

Code:

#!/bin/sh
traverse()
{
 for i in *
  do
   ls "$i"
  done  
    if [ -d "$i" ]; then 
        cd  "$i"
        ls "$i"
        traverse     
    else 
        cd "$i"
        for j in *.m4a;
          do
            ls "$j"
            faad "$j"
            x=`echo "$j"|sed -e 's/.m4a/.wav/'`
            y=`echo "$j"|sed -e 's/.m4a/.mp3/'`
        faad -i "$j" 2>trackinfo.txt 
	title=`grep 'title: ' trackinfo.txt|sed -e 's/title" //'`
	artist=`grep 'album: ' trackinfo.txt|sed -e 's/artist" //'`
	album=`grep 'title: ' trackinfo.txt|sed -e 's/album" //'`
	genre=`grep 'title: ' trackinfo.txt|sed -e 's/genre" //'`
	track=`grep 'title: ' trackinfo.txt|sed -e 's/track" //'`
	year=`grep 'title: ' trackinfo.txt|sed -e 's/year" //'`
           lame --alt-preset 160 --tt "$title" --ta "$artist" --tl "$album" --tg "$genre" --tn "$track"$ --ty "$year" "$x" "$y"
          
        rm trackinfo.txt
        rm "$x"
     done
fi

It maybe you absolutely want to do this by script... but I suggest you using some good sound converter, such as "soundkonverter" which I suggest, or transkode. Both can also be installed as amarok plugins, but for mass conversions I think that using the standalone program is better.

In addition to what you would do with your script, these programs also organize your collection in folders as you like and flexibly rename the files, and can work in parallel on more than one file, in case you have more than one cpu core.

If you still want to go by scripting, you could try to simplify it by using the excellent ffmpeg command line program, that basically converts from any audio/video input file to any output format.
