Check out bbb.  I have bbb-0.0.3-1.i386.rpm installed on my server (from
a *long* time ago).  You should be able to find it from
www.flyn.org/projects/bbb/download.html.  I think the current version is
0.0.4.

bbb is a replacement for burn_baby_burn.  Both are a set of scripts for
ripping/burning and generally dealing with CD/CD-R/CD-RWs.

I burned many a CD-R with WAV files using it years ago.
