Hi Marc,
I think it is, perhaps, a little pessimistic to talk of needing to assess
dozens of hrtf's to find the one that's right for for you, if you have head
tracking in use. My experience with this dates back 20 years to the days of
the Lake DSP Huron systems when I first heard this - even without specific
hrtfs switching the the head tracking on was enough to change the system
from not working (for me) to working. The head tracking (done with a
Polyhemus sensor controlling the processing of FOA B format signals prior
to decoding) was enough with no need to select hrtf's. I would suspect that
having just a few to select from would be enough.
