[Sursound] Merging impulse responces, is it workable?

[Bo-Erik Sandholm]

I want to introduce the impulse responce of a real room to a foa or toa
file with panned mono sources in fixed positions.
I have a few questions about how to create the best result in the simplest
way.

If I have the recorded bformat impulse responces of several sources placed
in the same positions where the panned sources will be located.

Questions on how to get most natural result:

Should each positioned sound source be convolved with positional specific
mono room impulse responce or a positional specific bformat RIR?

Can all separately measured bformat positional RIRs be merged as one
bformat RIR in any way, if so how?

Can the convolving be done in bformat after mixing to a single bformat file
or should it be done for each before mixing to bformat?
Should that be done with mono or bformat RIR.

How many convoling instances would be best to use in a setup?

Awww, come on, a bit of mental exercise is good for the soul! :-) :-)

Well, that said, (and this maybe a shock to those that know me) I'm
gradually moving towards the view that FuMa may have had its day. The only
remaining reason really is compatibility with with earlier materiel and
Soundfield mics and that can be dealt with conversion code, so long as
everything is properly documented.

Just do it. 

During the past months I've been explaining Ambisonics to some
people who are going to work on HOA based applications. All of
them are something like 20 years younger than FOA, and when they
think about Ambisonics theory that means arbitrary order. To them,
using anything but N3D, SN3D and ACN seems like a form of masochism.
Maybe because I made them work out X-axis rotation with FuMa in and
out as an exercise. None of them got it right.

Ciao,

A world of exhaustive, reliable metadata would be an utopia.
It's also a pipe-dream, founded on self-delusion, nerd hubris

Personally I dont think it makes a huge difference. There are quite a few
free converter plugins available now so when working in a DAW it's fairly
trivial to insert one of those and convert between FuMa and ACN as needed.
One possible solution would be to have an extra parameter in the plugin to
allow you to switch between formats,,, best of both worlds perhaps?
