This is very strange.  I get here:

octave:7> 20 * log10 ( max ( filtered ( end - 1000 : end, :)))                                                  
ans =

    -3.0103  -251.9348    -3.0935

Since I get the same values for a and b as yours, the only conceivable
source of divergence is the filter function.  What does "which filter"
yield for you?
