I got a demo called "snd2lt" from the SCEE Web site, which allows
you to play a CD-audio disc, and it puts up a light show in time
to the music, including a sprectrum analyzer.

It is really cool, and not hard to work with.  I modified it a bit
to make a few new light displays.  It comes with a function called
ReadCDDA(), which grabs the current sound buffer, and then you can
do whatever you want with it.

It's by a person named "Colin" (Last name strangly absent from
the Readme/code, so I can't remember exactally which http it
came from, but I'm pretty sure it was on the SCEE site.

The ReadCDDA() function is in binary form only (you link his
"cdfeed.o" object into your code), but maybe you can convince Colin
to let us all in on the secret!  :-)
