non-uniform quantising logarithmic compression
     
        the kind of compression often applied to a sound waveform.
        logarithmic compression is a good match for the human ear's
        sensitivity but cannot handle zero amplitude for which the
        logarithm is negative infinity.  there are two standard
        compression functions which give a smooth transition between
        the logarithmic function and a linear segment passing through
        the origin: mu-law north america and a-law itu-t.
