Just to pick a nit, the above can't be right. G.711 is a logarithmic recoding of 16 bits into 8. So each 8-bit value can be reached from a whole lot of different 16-bit values. The information as to which 16-bit value it came from is lost, so you can't get back to the original values, just to approximations of them. Also, I believe the 16-bit range is chopped up in slightly different places for aLaw than for uLaw, which could mean a slight loss of information going back and forth repeatedly between the two.
