When sampling at 44.1k, there are "Anti-aliasing" roll-off filters at around 21k that stop signals above the nyquist frequency (22.05k) from entering the A/D. If these signals were allowed to enter above the nyquist, they would produce artifacts somewhere in the lower range of the frequency spectrum (ie within humans range)
This is what I know "Anti-Aliasing" to be....maybe not the most detailed explanation, but the general idea I think
