Um, how can you possibly ever go over 0dBFS ? Do some homework as
understand just how silly that makes you look !

Firstly, YOU do your homework, the ANALOGUE output can go over the 0dBFS
level under certain circumstances. Look up Jim Lesurf's work on the
subject.

0dBFS relates to the digital signal only, IF the analog output goes over the
corresponding voltage level set by that card for a 0dBFS signal applied to
it, then its FAULTY.

Again, look up Lesurf's or Nielsen & Lund's work, or google 'intersample peaks', about
which pro recording/engineering boards comment not infrequently, I suspect there's probably a
thread or two about it here.

A standard ref:

With proper metering at the record/production end and proper D/A at the consumer end, it
shouldn't happen, but apparently that's asking a lot. Perhps things are better these days
than when that paper was written, I don't know.
