Ok, I'll have a go :-)
If you sample at 48Khz you need to filter out
everything above 24Khz in
order to avoid alias noise. First of all this is
not *really* possibkle,
filters don't block thay damp. Secondly a
filter
steep enough to let
ninimal amounts of energy through above 24Khz
will
be distorting the
upper part of the frequency range.Now if you
sample at 96Khz the story
is the same, but not you have an extra octave to
filter smoothly.
Another part of the story is that although a
48Khz
sample can represent
frequencies upto 24Khz, the representation of the
higher frequencies not
accurately describing the intensity.
Let's put it this way.. Do you think a CD sounds bad
? I think the average
person can't hear much about 18 Khz (could be 20 Khz
though).. So unless you
are a sampler yourself you probably won't notice. I
certainly won't go above
48 Khz since bigger is not always better.. Of course
a lot depends on what
sampler was used to capture the sound. 44 Khz could
be an option but I'll
have to have a look at the softsynths and hardware
