[linux-audio-user] is (88200->44100) better than (96000->44100)?

The big question is what program are you using for doing the sample 
rate conversion. If it is any program which uses libsamplerate there
is no difference in quality between going 96000->44100 and going
88200->44100, although the latter will be slightly faster in terms
of processing speed.

Whatever rate you choose, i would suggest capturing at 24 bit. You 
can then use something like Gnome Wave Cleaner to clean up the
recordings. The next step is to normalize and then finally converting
to 16bit 44100.

The final step of converting from 24/XXXXX to 16/44100 should also
include dithering which libsndfile does not do (yet, plans on the
board).

HTH,
Erik
