AMEN !


On topic:

Filter bank spacing of 2.1**(1/5) : This is to get roughly
5 filters per octave (quite dense spacing), while avoiding
two filters being spaced exactly an octave.
(5 filters per octave would be 2**(1/5). )

I wonder why we need such tight spacing in the low
range, however. If you take a violin, the upper modes
of the wood resonance are very close to each other
(thus using a filter bank to get a "string filter").
But in the lower range, you have just a couple of
singular resonant peaks (air resonance and fundamental
of wood resonance), haven't you?
