Well, I'm not a reverb expert, but my impression is that convolved reverbs
are the way to go*. The actual code is relativly simple, and we allready
have open source examples, and its possible for people with decent
recording equimpent and access to spaces with interesting acoustics, or
artificial reverb units to capture thier own impulses. They can also be
synthsised using a method similar to raytracing.

The downside is that the parameters you can control are very limited, and
it burns quite a lot of CPU power, and there can be latency. The upside is
that the sound can be very good.

There is an obivious technique to prevent any latency problems, but bits
of it are probably patented by Lake DSP, though the situation is a bit
murky.

If I had more time I'd like to take the code in brutefir and make it into
a DSSI plugin with a simple dropdown select-an-impulse, set gain type
interface.

I have a sizeable library of impulses, but unfortuantly I dont know the
provenance of many of them.
