Based on my own experience, it certainly happens, though I can't say
why, it may be resampling or crappy hardware as others pointed, but the
distortion is there and audible. It becomes impossible to notice with
high sampling rate recordings (at least on PC hardware, have not tried
on portable players yet).
Maybe it can be avoided somehow, but disk space is cheap nowadays so I
find more convenient to just record at 96Khz and avoid headaches.
Below
that you will have more then four samples to reproduce the sinus wave.
That is in fact another reason to do the recording, mixing and mastering in
more then 44kHz...
This is a pretty bold claim, and contradicts Nyquist and other literature.
Do you have a citation for the claim that frequencies "as low as a quarter
of the sampling-rate" are damaged by sampling?
