That I think
is a personal call Ralf, primarily because at 48 Khz, your
anti-aliasing filters had better be very very good brick walls by the time
you get above 24Khz in input content
Can anyone point out a commercially available microphone used in the
audio recording domain which will actually pic frequencies above 20 kHz?
Likewise can anyone point out any commercially available speaker used in
the audio reproduction domain which will actually reproduce frequencies
above 20 kHz? If the audio produced is made for fruition of humans
it makes absolutely
no sense to try and capture or reproduce anything above 20kHz, and for
average individuals 15kHz would probably more than enough.
but of course you need to distinguish between distribution and
production, were you can benefit from frequency headroom.
And in case anyone is tempted to state that even if we
don't hear them
frequencies above 20kHz influence the way we hear or 'perceive' music,
please also attach any _scientific_ study/paper/evidence (e.g.
large-scale blind tests etc. not anecdotal evidence) to such statement.
