Not necessarily. I have a few CDs which light OVER on digital record and
then when played back. I suspect OVER just means the sample was +16383 or
-16384. No audible clipping is heard.
+16383/-16384 is not an invalid sample in itself. But obviously, unless the
recording has been digitally scaled, it is likely that this sample value
would mean clipping.
