Great to see that mentioned.

It has always struck me that we can indeed adapt remarkably quickly to local changes in our personal HTRF, and that therefore this needs to be considered as a dynamic affair, rather than a purely static one.

If you suffer a temporarily blocked ear - after swimming, say - your stereo perception may be bent out of accuracy for a few minutes, but the (extreme gain/frequency  inaccuracy gets accounted for within our brains and we soon find visual and aural alignment back more or less correctly.

Likewise putting on wooly hat, a coat with a thick collar, or a heavy scarf - all objects that should wreck the accuracy of a static HTRF - have only the most limited of effects on positional accuracy.

So how much precision is really needed for an HRTF? And how inaccurate can it be for our normal correction ability to deal with it?
