The website does seem to be evolving, with the English pages catching up
on the Chinese pages after a few days. There's now an English pre-order
page on http://yun.twirlingvr.com/index.php/home/Lite/lite-en - odd, as
most of the English pages are on http://yun*-en*.twirlingvr.com

As you say, it's worth a punt.

I asked a few questions and received the following reply:

Hi Gerard,

Thanks for your interest and please follow this link to the English 
pre-order site: http://yun.twirlingvr.com/index.php/home/Lite/lite-en

And for your questions:

 *
   The Lite works directly with all Android phone with USB port. For
   the type-c port, we will provide a converter.
 *
   The original recording format is A-format, but we will provide a
   phone App that allows you to export file in SN3D format.
 *
   Except for the phone App I mentioned above, we will also provide a
   PC software( Twirling720 Studio) which is a more professional tool
   for users to convert the recording file into multiple formats,
   enable noise suppression, change the sound field, preview sound/360
   video file by dragging the mouse and so on.
 *
   We will carry out a series tests in the before sending it to the
   customers, any device with any imperfections will not be allowed to
   go out. We will make the Lite be configurable and try to provide
   individual's calibration file./(The question was do they provide
   calibration files)/

Please let me know if there are any more problems or any confusions.

Best Regards,
Huiyu

Re: [Sursound] Cellphone tetrahedral

[umashankar manthravadi]

I too have created an account, but I think I will pay them 89 dollars and buy 
one. It looks like a four channel mic preamp plus a-d direct to a USB 
connector. I should be able to record to a desktop of laptop and use X volver, 
Brahmavolver or VVencode to produce B format.

I am broke, but this is sacrifice for science.

I have a lightning to microUSB adapter lying on my desk.

Going through their website I find a picture of it connected to a
laptop:



Going further (and navigating account creation and login in Chinese) I
found a page with download links for the Capture SDK for Windows, Mac,
Linux, Android, and iOS:



Capture, in case you can't get to that without a login:
