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 On 4.

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...)

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 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!

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?
