mastering that hot is a major technical blunder proposed by idiots with
either bad hearing or a profound hate for music.

> Out of interest, how high can intersample peaks get above the highest

imagine the positive half of a sine wave, so that two consecutive
samples representing the very top of the wave are at 0dBFS. it is clear
that between those samples, the real peak value of the sound must be
higher than 0dBFS, and the reconstruction filter will see this higher
value. that means unless your analog stage has headroom for this, it
will clip. the higher the frequency, the higher above full scale those
inter-sample peaks can be.

ok. though i have a hard time seeing any use for peak normalisation
unless you want to deliver your material at low bit depths, such as a cd.

>>> " --peak

correct replay gain should strive for constant perceived loudness, so
that you can use those wonderful evolved fingers for more important
things, such as doing the dishes or ironing, without having to rush to
the volume knob after each track.

>> like julien suggested, use a standard peak normalizer and then attenuate

i hope that come spring, your freshly thawed brain will even realize
that you don't want peak normalisation at all :)

ok, down from the soapbox, and season's greetings,
