Citando Augustine Leudar <augustineleu...@gmail.com>:
Hi Jack,
Aside from ILDs, ITDs, I also wondered if the pinna was able to distinguish
very close sound sources due to the fact the wavefront would be much more
curved almost spherical to the degree that it would be different pressure
present at different folds of the pinna (ie very close up sound slike a
mosquito) . I dont think theres been much done on that...
Hi Augustine,
I think "there has been done quite a lot on that"... 😉
(Reproduction of near-field audio sources)
Beside of spherical waves (and their consequences) we should not
overlook that any high-frequency emitting (annoying) mosquito next to
your left ear would be heard much softer at your right ear, the head
shadow being even more relevant at close distances.

P.S.: It is important to know about the "depth" of a mosquito audio
object relative to your head, both in VR and in real life...

It looks like a method for binaural rendering with multiple distance HRTFs.
Ambisonics could be one of the inputs, but it seems to be aimed more at
object based virtual reality, where the listener is more likely to come
very close to an audio source.
Most HRTFs are currently measured at 1m distance, so any objects closer
than 1m are not currently rendered correctly.
Far field HRTFs are closer to plane waves, whereas close up audio objects
emit more spherical waves, creating greater differences in interaural time
difference (ITD).

I don't know a lot about patent law, but is this an attempt to tie up our
beloved Ambisonics?
