Like others, I'd suggest *avoiding* normalizing or limiting to anything
close to 0dBFS. if you normalise to within a dB or so of 0dBFS you'd need
to check any CD player you use can then handle intersample excursions
produced by the DAC/reconstruction filter that rise above 0dBFS.
Is that *really* an existing problem ur an urban myth?
It does exist on a few model players.
The Red Book
specifies 16 bit data. Why would they do that if a player would not be able
to reconstruct full 16 bit data to an analog signal?
Because the Red Book was written before any of the players existed.
to me this would really
be a severe design flaw in a CD player! If I were the designer of a DAC and
I would expect that an interpolation between two samples would rise above
the maximum dynamic range, I'd add the necessary bits to take care of that
or scale the input of that process down. In my DSP work I always checked the
input range and output range of calculations to see if it would fit in the
'width' of calculations and scale accordingly. This is standard design
practice.
Consumer equipment is designed to be as cheap as absolutely possible.
