I never did it, but with a burn-proof capable recorder it should work.
cdrecord will accept a standard stereo 16-bit audio stream. This
example comes from the CD-Writing-Howto:

  for I in *.mp3
  do
      mpg123 -s $I | cdrecord -audio -pad -swab -nofix -
  done
  cdrecord -fix

For realtime recording, I would use of course ecasound, and probably
(untested) this command line:

$ ecasound -i:alsa,default -f:s16_le,2,44100 -o:stdout | cdrecord -audio -pad -swab -nofix -
$ cdrecord -fix

Try this on a CD-RW first.

ciao
