Burn audio cd


I have a dir with a few mp3-files that I want to burn to an audio-cd.

I tried to do something with cdrecord but I first got an error and then I tried to as the error said and use the -pad-option but then the cd just got "fsck"ed up (it's a joke, not fsck).

Code:
$ cdrecord dev=/dev/cdrom -audio file1.mp3 file2.mp3 [...] fileN.mp3

Do you mean you want to create an audio CD with each track containing an mp3 file?

The good news: you can burn such a CD, just the way as you did it using the -pad option.

And now the bad news: no player will play those tracks, since standard audio CD tracks should contain raw PCM data, and not mp3 :-(.

So, either you write those mp3s onto a data CD, or you extract them into raw PCM, and burn an audio CD.

Yeah I thought that the type may be the problem. But then my question is: how can I convert from mp3 to whatever you told me to use (I have read about so many types so I can't remember them all, wav, cdda, etc. So many terms. :P).

How shall I burn when I have the correct type that can be played in a standard cd-player?

You have to do four things:

1.) Decode the mp3 files to wav:
lame --decode fileN.mp3 fileN.wav

2.) Resample the wav files to 44.1kHz bitrate
sox fileN.wav -r 44100 fileN-new.wav resample

3.) Normalize the volume
normalize -m *new.wav

4.) Burn the files onto a CD; you already know how to do it:
cdrecord dev=/dev/cdrom -audio -pad file1-new.wav file2-new.wav [...] fileN-new.wav

The above should work, though I never did it myself; these are all the result of some google searching I did.

OK, here is a little script of mine that is supposed to automatize audio CD creation using lame, sox, normalize and cdrecord:
Code:
if [ -z "$1" ] ; then
  echo "Missing parameter: Location (directory) of album"
  exit
fi
if [ ! -d "$1" ] ; then
  echo "Error: album location $1 does not exist"
  exit
fi
# Decoding mp3s and resampling them
for file in `find $1 -name "*.mp3"` ; do
  echo "Decoding $1 to $1.wav:"
  lame --decode "$file" "$file.wav"
  echo "Resampling $file.wav to $file-new.wav"
  sox "$file.wav" -r 44100 "$file-new.wav resample
  rm "$file.wav"
done
# Normalizing volume
normalize -m "$1/*-new.wav"
echo "The files should be ready to burning onto CD now:"
ls -l "$1"
echo "Do you want to burn them now?"
read choice
case choice in
[Yy]) cdrecord dev=/dev/cdrom -audio -pad `find $1 -name "*-new.wav"` ;;
*) exit ;;
esac 
echo "End"
The script should be used as follows:
/path/to/script /path/to/album

If you find that the script could be handy, then feel free to debug it, as I wrote it in 5 minutes and I never tested it.
Also it might need some addition to handle spaces and special characters in filenames, which could cause some trouble in the present state of the script.
A last note: the linuxquestions.org forum software always replaces the double "[" and "]" characters in the if constructs of my codes, so you must possibly correct the if construct syntax you find in my post.

Cheers

Edit:
This time the linuxquestions.org forum software totally ruined my code, so I had to replace double "[" and "]" characters by single ones just to make the script readable here. So, please double those characters in the if constructs before using the code.
