So I tested a familiy of numbers based on a = ln(2)
that should read g= ln(2); (a ~= 0.76597)
It seems one of the best, but why?
Counterintutively, there is no solution for g=a for N =2 (except g=a=1);
(the solution for g=a and N=3 is 1/golden ratio )

That would be a paper on numerology then...
I generalized a bit:
Na - 1 = a*g
a = 1 / (

I found found one paper on the topic, they use a structure similar to
the Schroeder design but with nested AP filters:
3 Parallel Combs -> 3 Nested APs -> Lowpass ->
for room reverb.
They used a genetic algorithm to

I hope the formatting stays in place.
The feedback delay in the loop folds the signal back
so we have periods of a comb filter.

I think, the lack of literature is based on the highly subjective matter of
taste. There are some papers on reverb tanks, that generalises the tank as a
lossless system, etc. But these all pass chains are mentioned rarely. Schroeder
investigated these stru

I think, this structure you mentioned (2 AP filter + delay and a feedback node)
has been investigated by Bill Gardner. I used this structure, too, but it took
4 allpass filter to make it work. But still it has a repetitive sound, which
goes away, if the feedback factor approaches 1.0. So, itâs a
