Mike, I already know how to use the ATK kernels in custom applications
(a bit of convolution and the job is done). I never tried the Super
Stereo kernel, and I did not think about it for my use case. What's
happening under the hood doesn't matter much (at this point), and I
trust anything ATK. This is a great suggestion, hopefully it'll work
just fine, even with binaural recordings.
Thanks! :-)

Hi Marc,
You may consider trying the “super stereo" technique to encoder your binaural
recording into FOA. You could quickly audition this in Reaper using the ATK’s SuperStereo
encoder<https://www.ambisonictoolkit.net/documentation/reaper/>. It has a very
satisfying “wrap around” impression once decoded from FOA. As I understand it, there is
some frequency dispersion across the lateral hemispheres in FOA to achieve this.
Note that this is not the same as “super stereo” effect you may find reference
to online (relating to listening to UHJ without a decoder). Jo Anderson
authored the encoding kernels and may have more details on what’s happening
under the hood.
My best,
Mike

I don't expect this "conversion" to be precise, or as a mean to archive
binaural recordings using ambisonics; my intention is simply to use binaural recordings
for an art installation with small speakers close to the user; I suspect it would feel
better with a quad setup than a stereo setup, because the user would move (turning its
head and/body).
See the "Binaural to B-Format" section of https://www.ambisonic.net/quaduhj.html, then
the Pan-Rotate section of "http://www.ambisonic.net/ambimix.html";; How to do something
similar with software methods?
I'll try a few things, but maybe someone in the large Sursound community did
something similar?
(All we see now on this mailing list are academic/commercial announcements, so
please excuse my naïve question...)

There might be something that uses crosstalk cancellation that might work
for a normal two speaker (transaural) approach? Although I can't see how it
would work for quad though - or why youd need to use ambisonics fo it. I
know Spat has a binaural transaural converter - which can also convert to
quad - but I dont know if you can use your own recordings - I think it's
just for stuff panned in the software....

I'm, not sure there would be Marc - I can see how it easy enough to
convert in software ambisonics to binaural by convolving with HRTFs and
potentially the other way round too if you used the same software that was
convolving HRTFS to output Ambisonics (or even plain old quad) but a
recording with your own personal HRTFs on it ? I cant see how - unless
theres some super software that has your personal HRTF , can get that data
from the recording (which sounds very difficult) and convert to
ambisonics/whatever - would love to be wrong though!

I have a "back to the basics" question.
For a simple project I planned to record in FOA or HOA, but the final
render would be in simple quad (horizontal). So I don't need a lot of
resolution. I enjoy recording with binaural microphones (the kind that
looks like cheap earbuds), so I can record continuously without being
noticed.
So I wondered; is there a method to "convert" binaural to
horizontal-only FOA? Apparently there is:
https://www.ambisonic.net/quaduhj.html
http://www.ambisonic.net/ambimix.html
I guess my question is: what would be the software equivalent of a
pan-rotate device?
