On the contrary, the brain is pretty good at detecting cyclic
variations in most situations, sound in particular. Mixing multiple
tabels with different lengths might hide the effect a bit, but I
believe it has to be something like an XOR operation to work - which
pretty much eliminates any precalculated noise shaping done on the
tables...
