i think, with these algorithmic reverbs (FDN or Schroeder) you can spend
forever tweeking coefficients. If it's a convolution reverb, then it needs
really good choice of which space and where the transducer positions are. you
can tweek those parameters forever.

think of the FDN as a plate reverb. that's gonna be how they sound. dense.
they're not rooms.
i dunno, but i think these FDNs might mostly be used as musical effect (like
those reverse reverbs that sound like high hat) and not to make it feel like a
real room somewhere.

i'm sorta uncreative. i just relate the lengths of the delays by some ratio
and then look for prime numbers. isn't that what Jot did? i don't remember.
