I just changed my CSound filter bank to 30 filters
with the 2.1^(1/5) spacing and Q=25. Now I am getting
the results I was expecting. I don't know why this
should be different that what I had before, which was
36 filters from 100 to 8K. But it works much better.

Now that I got past that stumbling block, it is time
for the next stage; a DSP filter bank module.
