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 distan

As far as I know, higher order ambisonics over loudspeakers has a quite
confined sweet spot. Higher order spherical harmonics produce an in phase and
out of phase signal in opposite speaker pairs. So if you pan a signal towards a
particular speaker, the opposite speaker will produce a lower leve

I recently built a tetrahedral array into a zoom h2n, but had problems with the
m/s encoding of the first two channels eating into the already limited headroom
of the mic pres. The signals are added together on the m channel and the
resulting recording levels are very different on the first two
It’s just four cardioids pointing outwards from a central point, so you can use
them as individual signals if you want. Or encode them to B-Format or any
number of other virtual microphone arrangements.

You can set the output of the Røde plugin to B-Format ambiX. You may also want
to experiment with something like harpex for upmixing to higher order

The only problem with using ambisonics mics is the high frequency limit
above which they stop working properly. A second order ambi mic reduces
this problem, but above about 7Khz the not quite coincident capsules

Sorry, I should made that more clear.
The 7kHz limit is for your average first order ambisonic mic, which has been
improved on by second order mics.

Hi Len,
As we’ve discussed before…
This simply isn’t true.
If you add two omnidirectional microphones together you get a 6dB increase in
peak audio signal (voltage) but only a 3dB increase in noise because noise is
an average power. P=I^2*R and V=IR. The square makes the difference.

What is your point?
