a) any
non-linearity introduces harmonics, some non-linearities
introduce an infinite amount of harmonics, which will cause foldover
distortion. the large the sampling-rate, the lower the foldover.
You should not have any non-linearities, except those introduced
on purpose, i.e. distortion plugins and the like. And then it
all depends on how these are designed. If done well, they will
not add any aliased components. One way to avoid that is using
higher sample rates internally, but it's not the only one. frankly, 48k
may be a good enough for distribution, but it is
sub-optimal not for production ... and it is horrible for digital
synthesis.
Only if you use 'primitive' algorithms. Unfortunately there's
a lot of those around. In summary, 96 or 192 kHz will allow you to use
simpler algorithms.
or get better sound quality from existing plugins ;)
