Rant:

I would suggest you convert FLAC files to MP3 instead making AudioCD. Why?

1. You can't possibly notice difference between lame -V 5 (or even lower) and original source listening in a car


2. You'll save yourself time in the process and save $ on plastic, as space needed would be ~10 times reduced this way, plus you wont need to browse for CDs to find single album ;)

Procedure:

1. Convert FLACs to MP3 with lame (lame recommends -V2, but in your
   case I'd go with -V5):

   
   
   

   flac -d -c track.flac | lame -V 5 - track.mp3

   
   
   

   example for processing all FLAC files in current folder:

   
   
   

   for f in *.flac ; do flac -d -c "$f" | lame -V 5 - "${f%.*}.mp3" ;
done




2. Convert MP3 folder structure to Joliet folder structure ISO image
   
   After you have converted FLAC files to MP3 arange MP3s in folder structure (i.e. /artist/album/track) than make ISO image like this:

   
   
   

   mkisofs -J -o /tmp/MP3-CD.iso /path to root of MP3 folder
structure/

   
   
   

   Note: you can't go above 700MB, check for space first




3. Burn ISO image

   
   
   

   wodim dev=/dev/sg1 -dao speed=8 -eject /tmp/MP3-CD.iso

   
   
   

   Note: Use wodim --devices to check for your device.
   dev=/dev/sg1 is valid for my system
