Hmm, I meant that they are nicely externalized in all head-related
directions. You know, with some binaural systems it is hard to get
auditory objects externalized in field of vision, they tend to jump inside
the head, although they are nicely out-of-head in sides and back of the
listener. In this case no externalized auditory objects exist.
Perhaps even bigger advantage of having both head-tracked video and audio
available is that you seem to adapt to the HRTFs used in DirAC rendering
very fast. After listening only a few seconds to the recording with moving
the head at the same time leads to plausible perception of the
reproduction. Even in the case that when you look down or up, the auditory
objects stay in directions constant with the world outside.

Sorry, not currently any change to share the demo. We are hoping to share
DirAC software, at least with some cases in future.
You are welcome to visit Helsinki, we have also some other cool demos.. :-)

They are not joined at all, the player inputs separate spherical video and
B-format audio files.
