Default What is the best order to process audio

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? 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? 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.


No, it's a legitmate problem with some gear, and I'm inclined to agree with
Jim on why.

For demos that I'm going to distribute I set the peaks to -1 db, which is
fine with all the players I've encountered.
