Hi Steven,
(hurried reply on the go) the numbers were for 17cm diameter (8.5cm radius).
You also get around 15-18dB SNR improvement just by combining that many
microphones, that’s still included in that simulation.
I wasn’t saying that the device is not good or useful, apart from the video,
Hi Archontis
The size is 170mm diameter not radius.
They also state the capsules are in arrays of 16, so 4 arrays of 16 capsules.
Looking at the camera though, I can’t work it out….
The also said:
'The noise and frequency respond i quote is for individual mic. We have noise
reduction
Hi Steven,
as Fons mentioned before such an array will have trouble to deliver proper HOA
components at a useful range. Running a simple simulation here for R=17cm and
assuming perfect matched microphones and perfectly (uniformly) arranged,
spatial aliasing starts to become serious at 4.5kHz.
Surprise suprise, they can't provide a 3rd order sample at this point in
time
Here is the message.
"We talked with our R team regarding to the schedule of audio. As our
timeline is to achieve the 3rd order Ambisonic in first shipment in
October, from now to October we still have a lot of
I just messaged them, apparently it will be. They will be also providing access
to each individual mic stream via a software upgrade!
‘Yes, 3rd Ambisonic will be in the first shipment, but 5th order Ambisonic
rendering will be provided in the early next year, by upgrading the software.’

I notice that although it is a Ambisonic microphone, the audio is
rendered as a stereo binaural stream; it's not clear if the Ambisonic
stream is available. But often, Kickstarter campaigns are hiding
important details to target specific markets.

Hi all
Just seen this...
https://www.kickstarter.com/projects/303473622/affordable-professional-360o-sound-and-video-camer
It has 64mics, plus 9 4k camera's and is a lot cheaper than an Eigen mic.
Any thoughts? As it's got my attention.
Steve
