maybe using the differences from the last values would be more
accurate (lt = left_ch[i] - left_ch[i-1]; ...)

and i think though i might be wrong that the sum of absolute values will
be a better choice then the sum of squares for estimating the number of
bits which is after all what matters in the decission of the decorrelation
method

except these iam fine with the patch
