you already have to tweak the two psychoacoustic bands.

i don't think ambdec can do much about it, for the reasons you mention,
and for the fact that the subs will be physically misaligned wrt the
tops. so what we need is a delay (already there), and maybe, just maybe
some "+/-" buttons for the delay to help with a setup by ear, and a tone
generator that creates test signals in the critical overlapping band -
these could then simply be tuned for maximum loudness.

oh, certainly. it would be divine to *not* be able to do evil sum
compression in ambisonics, ever, but sometimes, earthly matters require
it...

but my favourite solution to this approach would be for ardour to do the
right thing wrt side chaining (or at least allowing the chains to be
made manually). i'm told a3 can do it, and i'll be checking it out.

but yours would certainly a welcome addition to my tool chest.

N-way side chaining would be cool, with just a single set of controls.
the interesting question is how the measuring should be done and the
orders interpreted. and here we go again, at normalisation and channel
order ;)
