Or maybe not?
Acousticians speak of "Head-related Transfer Function", whereas most
scientists in other areas use the term "Human Transfer Functions".
A second observation would be that shoulder and body reflections don't
seem to play a role if you measure anechoic HRTFs. (Appear only in
"long" HRTFs.)
Best,

Headtracking should apply only to signal that will be binaural and HRTF
processed. The other part of the sound should not have headtracking applied. I
nearly twisted my neck this morning listening to the hiss of the gas stove and
turn my shoulders without turning my head, not enough data. But just
commonsense tells you the brain is probably using the rotating head information
against a quasi static soundfield that includes body reflections.

Richard Furse’s Blue Ripple Sound uses HRTF tinting in their
decoder, it works very well. Although I think he may have a patent
on it…:)

Hi Steve,
what is HRTF tinting? I haven’t heard the name before..
Archontis
There's a description in the text of the patent:
http://www.freepatentsonline.com/y2015/0262586.html
http://www.freepatentsonline.com/20150262586.pdf
How multiple drivers can use HRTF tinting is unclear.
(but as most patents, they are difficult to understand).
