I have a 512 mb Muvo Mp3 player that I use when I jog. I like to compress my LAME encoded MP3's to 128 CBR in order to maximize the amount of music on it. I don't change the songs very often because I have to reprocess each file every time I want to do this. What I am looking for is a way to compress all of my MP3's down to 128 CBR. The catch is all the files are in structured subfolders IE.(A-D\Artist\Album). I want re-encode the files into a new folder. Is there a way to do this in EAC...If there is I can not find it. Or can someone recommend software that can do that?

Thanks

Probably could be done with a batch file or shell script if you're handy with that sort of thing.

Check out dBpowerAMP. While perhaps a new low in intraword capitalization, it's designed to do that kind of thing.

Something like this:


for f in *.mp3 ; do
lame --preset cbr 128 $f new.mp3 && mv new.mp3 $f
done


Cheers

In that case:


mkdir new
cd old
find . -type d -exec mkdir -p ../new/{} \;
find . -name \*.mp3 -exec lame --preset cbr 128 {} ../new/{} \;


Cheers

Man this is why this is my favorite forum...quick precise answers....Only thing is I don't know what to do with the script. Where is this entered? In the command line options for LAME or from a DOS prompt? I am assuming the former. The multiple lines are throwing me off because I don't think there is more than one line to enter command line options in EAC. I really appreciate the help but can you dumb it down for me?
Thanks from the village idiot

You can't really use those commands because, despite the fact that Mark knew you were using Windows, he gave you Unix commands, in order to make a point, one would assume. Probably easier to just go with the dBpowerAMP stuff. Alternately, you could download the Cygwin environment and install it in order to get the commands needed to use that script.

dBpowerAMP isn't scriptable through the command line, but it does have an API. I wrote a quick Delphi app to use hymn and dBpowerAMP to transcode my iTunes songs before the newer version of iTunes broke hymn. Maybe I can tweak it to do what you want it to...check back with me tomorrow.

Any reason for the CBR only though? You can still use VBR with a roughly 128kbps average.

128kbps CBR just doesn't cut it for me.

128 VBR would also do. Actually it would probably serve me better.

I use MusicMatch for this because it has a quick little "Convert" feature. The version of MusicMatch I have is really old, but I paid for it so I figure I need to get use out of it. It handles LAME files with ease.
