However, even in presence of a tradeoff that makes some sense (i.e. each
of the two choices has advantages and disadvantages), it seems to me
that for audio applications the generated high-frequency noise due to
discontinuities should be _hugely_ worse than the passband-non-flatness.
Judging from the graph, it seems that the differences in the
passband-non-flatness are much smaller than the differences in the stop
band. But then again, maybe I am tricked by the logarithmic view.
Hmm, I don't think they can be compared at the same scale - though I
don't know with what scaling factor thay can be compared - or if it
makes sense at all to compare them quantitatively.
However, when one has to evaluate the ripple of the flat part, one
usually zooms in quite a bit...
