Setup

We'll be using a few programs for this.

pacman -Sy lame cdrdao

Let's configure cdrdao to use our CD burner. First, we need to find out how cdrdao can find the device.

cdrdao scanbus

If you have an IDE drive, you will probably be using ATAPI:0,0,0. Open up /etc/cdrdao.conf (as root), and enter the device name and node, in this format:

write_device: "ATAPI:0,0,0"

Decode the MP3s

First of all, copy all the songs you want on the CD to a folder. It's best to rename them to reflect the order you want the tracks to be laid out (such as 01.mp3, 02.mp3, etc). Now we're going to decode all the mp3s into uncompressed wav files. Please realize that a full album can take up more than 800MB in wav files alone. This will take some time.

mkdir wav
for file in *.mp3 ; do
   lame --decode "$file" "wav/$file.wav"
done

Create a Table of Contents file

Once finished, let's make a Table of Contents file that describes the layout of the CD.

cd wav
{
  echo "CD_DA"
  for file in *.wav ; do
    echo "TRACK AUDIO"
    # echo "PREGAP 00:02:00"  # insert a 2-second silent gap before each track
    echo "FILE \"$file\" 0"
  done
} > toc

Burn

Finally, all we have to do is burn the CD.

cdrdao write toc
