That's really a measurement problem. If you actually
know exactly what the "peak of peaks" is, that can be
just shy of 0dBFS. I agree in practice a 3dB or so
margin between *apparent* peak and 0dBFS is advisable.

What millenium are you living in guys, look at the
waveform, does it hit 0 dB FS?


How do you look at an analogue waveform?, we are talking
about setting the analogue level into the ADC.

You can, of course, do a transfer, look at the resulting
digital waveform, and then re-do it if the levels are way
off, but generally it's easier to get it more or less
correct the first time.

Most audio capture software has a real time display.

Yes, but is it accurate real time display, modeling
a reconstruction filter?

I don't know that those are so common. HEre's one:
