I believe you're right: binaural is just stereo with a twist. So hopefully the SuperStereo ATK kernel will work. There's probably other methods, and if they are linear I could capture them as IRs and apply them to the binaural recordings (in real time). I would also buy beers, but I don't go

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.

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. It has a very satisfying “wrap around” impression

yeah - I read the binaural to Bformat section. But the problem is with what they describe there that I don't think it would be any different from converting a normal stereo signal to b format - in fact it could even be a little bit worse. Its nothing to do with Kemar heads - just the fact if you

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

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

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
