There does seem to be a lot of interest in ambisonics to binaural these days. It certainly seems that way to me since I’ve been immersed in it of late.
Stefan, if your suggestion to the folks at JauntVR is what turned them on to ambisonics, then I must thank you as I have been having a great time working with them to provide custom ambisonics code, including binaural conversion. I expect that I will also have some level of binaural conversion out in general purpose plugins eventually.
