Oh dear, I seem to have gotten my indention levels mixed up. Quite a sin for a
C++ programmer. But I am reminded of what someone said in a C++ forum once, ‘…
aren’t all C++ programmers pedantic?’ No relati
time working
with them to provide custom ambisonics code, including binaural conversion. I
expect that I will also have some level of binaural conversion out in general
purpose plugins eventually.

I might also suggest, as a point of comparison, to test against a simple
mix of the inputs. Ignoring fine points like shelf filters and NFC, a
figure-8 decode is simply L=X+Y, R=X-Y.

I've been thinking about how this discussion might apply to a couple of
things I'm working on and it seems to me there are two different problems
here.

I've downloaded Unity and 3Dception's existing stuff to play with and my

it's a great environment to work in. And 3Dception is well integrated into
the Unity world.

Emanuele,
As you may be aware, I have recently released VVEncode with Brahma support
that will run in ProTools. This is hardly makes even a minimal suite,
though. I know of no rotate unit for ProTools, for example. It's my goal
to produce encode, decode, pan, and rotate for VST/AAX/OSX/WIN, but
y google cardboard demo when I manage to get it up to the app
store, but here's an .apk file for those of you who can get that to your
phone on your own.

On Sun,
ormat clip player, but you can switch it
to a second ambisonic bus that is not rotated for things like background
music that shouldn't track with head movements. If I remember right,
MPEG-H supports two ambisonic streams for just such reasons.

ar in the VR world is 20ms "motion to photons". Minimum
frame rate of 60Hz, preferably 90-120Hz. These faster rates do not allow
convolution with the full block size of the listen database, though careful
truncation should be OK.

my everyday bluetooth headset, built for music, is
useless for VR because of latency. And if you headphones are going to be

Certainly the easiest workflow would be to simply decode your B-format to
your bed format, 9.1 or 7.1.4, and mix into the bed directly. I don't know
of any (released) decoder that does these layouts in a ProTools world, but
you can always just use 7.1 and ignore height to get things working.

then looking for a smooth or step-wise
response in the recording.

I have a friend that has contributed to the OpenSCAD project, so I know a
bit about that. It's a 3D modeling program/language that works by writing
lines of code instead of pushing things around with a mouse. Because of
this, you can have parameters for things like size or number of teeth on a
gear
I recently developed a MatLab script to create calibrations based on
Angelo's method. Set up equations for each measurement's expected results,
find the LMS solution in each frequency bin, then build the resulting
filter matrix. A little engineering around the low and high frequencies
and it seem
matching higher order decoder ready too, but only if I get back to
programming ...

Given that this is a Brahma, it uses FFT based processing. My suspicion is
that the artifact is actually something in the FFTs like a windowing
problem or a bug handling the first FFT bins. At 48kHz, 1K block
boundaries would be about 48Hz.
Does using Xvolver give the same artifact? IIRC I read
re extreme results in the direction of one
capsule.

I can't speak for Harpex (and I can imagine reasons why it might not
work), but it should be no problem to use two copies of VVM
If you have any kind of calibration involved, rotating before running
the A to B process makes that calibration meaningless.
In fact, I'd say that one of the main reasons B-format exists is
precisely that it makes processing like rotations a reasonable and
general thing to do.

ways to track a sound once you know its source as Fons discussed. The
best way to go depends a lot on what your goals are.

Sounds like a great project. I have long been playing with Teensy's and
ambisonics including porting both encoding and decoding there. My code
