Upgrade from 2Hz to 0.4Hz resolution for Room Correction worthwile?

So your question comes down more to a case of selecting which
partial/imperfect solution has the set of flaws that your more
willing to live with.

Thanks for your help, Dick. Going from 2Hz to 0.4Hz resolution
increases the uncertainty in time. Whether that is desirable or not
(how well is the implementation done) can only be evaluated by
listening I guess, but that requires 2 Tacts, one with 2Hz and one
with 0.4Hz resolution...

I think you are using FAR to restrictive a meaning for "uncertainty,"
It's not that we "don't know," per se, rather that in order to achieve
the higher resolution in one domain (frequency), you will end up with
a broader realm in the other (time). Conversely, if you require a
broader time segment, you cannot avoid a finer frequency resolution.

Implementation wise, there is no INTRINSIC reason why a processor
capable of 0,4 Hix resolution could not be configured for 2 Hz
resolution: it's simply a matter of telling the algorithm the
length of the time window. The switch between the two may not
necessarily be instantaneous, as you ar eprobably required to load
a different set of filter coefficients for each, and there is
the matter of the delay through the filter and all that.

Whether this particular device allows you to do that easily is
another matter altogether.
