Yep - thanks Len - that was certainly my experience with SBLive and
onboard sound.
With the Focusrite Scarlett 2i4, it actually seems to run with
(slightly) less CPU load at 44.1k than 48k (much less than 96k), and
I think it might make 44.1k a better choice to avoid the extra
downsampling etc. for the final mix in that instance. Not sure if it
actually runs natively at 48k or whatever tho - not sure how I would
find that out.
The focusrite will clock the ADCs at whatever rate you select, it will
not resample. However, the low pass filter at 44.1k will have more
effect on the in band audio than at 48k. Do a listening test, if you
can't tell the difference with cymbals and such, I guess it doesn't
matter. If your mics roll off at 18k (or less) anyway it may not be an
issue. But honestly my engineering is not the best here.
That's the experience I've had here also with my RME Multiface II:
Despite that it's been regarded as a nice interface (and it is!), I've
found that it's *much* darker sounding at 44.1/48kHz, and only seems to
have full clarity in the treble at 96kHz. Since I really doubt that my
ears need the ultrasonic frequency response that desperately to get nice
treble, I'd say it's probably the filters, owing the effect you're
describing and others have mentioned in other threads in the past.
Some hardware isn't just 96kHz -- it's designed for it, and the filters
won't let it sound good any other way. If you have such an interface,
the sample rate question is already answered for you. You just have to
listen to it at the slower sample rates and see if it still sounds good.
If not, you may end up choosing 96kHz just because that's what your
audio interface's filters like.
