I'm guessing that you need low-latency HOA processing while working
with other Matlab/Simulink bits and bobs for data capture (headtracking?)
in real-time?

If you don't have a Matlab expert on the team you could end up spending
quite some time on just writing MEX files -- not on research --
but if you ARE fine with a bit of data janitoring* then one place to
start could be the Psychtoolbox that you may already be familiar with.
There's a low-latency audio framework in there with plenty of routines
that can be adapted for piping signals to and from your ambisonics engine.

Then there is "SoundMexPro". I have never used it and
I can't say whether it properly supports, say, Furse's HOA plugins,
but it may take a lot of work off your hands: www.soundmexpro.de
However, assuming that you can convince the department to drop the (sizable)
coin on that software, you should be aware that it's not open-source and
that you still may have do a bit of additional plumbing..

* Just joking. Is not all of research just data janitoring?

Re: [Sursound] Ambisonic on Matlab

[Ausili, S.A.]

Hi all,

Thanks a lot for your comments and direct emails.
Our intention is to use this installation for research. So, we need MATLAB to 
have a more controlled approach over the setup.
Now I’m looking to all comments.

Thanks again,
Seba.

Hello Seba,

Matlab could be useful in the design stage, especially if you have specific
requirements
as to accuracy in a complicated or unusual array layout -- in that case you
could have a
look at the Sound Field Synthesis Toolbox from the berlin boffins:

Subject: [Sursound] Ambisonic on Matlab

Dear all,

We would like to include an Ambisonic lab in our facilities and we don't
have experience in applying it so far.

We are thinking to use a big number of speakers (4th or 5th order) but we
are still looking for the best or most comfortable software to handle
this.

Because of that, is there any Matlab toolbox that directly provides you
the audio output for a certain order of Ambisonic?
Which are your recommendation actually to create a new setup?

Thanks in advance and looking forward to your comments.

Regards,
Seba.

 Depends, of course, what the facility is to be used for. If
 it's for
 artistic purposes, I would definitely agree with Augustine,
 go with ICST or
 Spat or something similar. If it's for scientific
 investigation, then
 Matlab or Octave or Scilab would probably be best.
