Firstly, thank you for the new plug-in, looking forward to trying it out, once
i het it working.
And a special thanks for the information about the level of 'W' being a little
'hot'
I did some quick tests of a couple of albums and after reducing 'W' by 3db
before feeding into your earlier
I've released a classic UHJ to square/rectangle decoder which can be found
at: https://www.brucewiggins.co.uk/?p=1836
It can also pass out B-format with or without shelf filtering applied.
It's a JS effect, so Reaper is the ideal platform (there is a JSFX VST that
should work on other DAWs,

Yes. It's a question of terminology.
When using impulse response files from Angelo's site, he has named the
UHJ to
"B-Format" conversion files , as _decoding_ (dec).
_Encoding_ (enc) files are used for conversion from B-format to

I convert UHJ to B-format using the Blue Ripple decoder (free stand-alone
program). Then whatever process you are familiar with can take you to stereo
using whatever microphone layout you prefer.

Hi All,
I'll reiterate Daniel's response. The ATK uses the word "encoding" to
describe transforming from _some encoding format_ to B-format (classic
Gerzon FOA).
To go from a UHJ stereo encoded signal (from a CD, or whatever) to quad the
signal path in the ATK would look like:
[ UHJ stereo
Maybe it's a question of terminology, but you need:
ATK UHJ *Encoder* (will convert UHJ to planar 1st order FuMa B-Format);
followed a B-Format decoder.

Good morning,
The procedure that Eero describes is a good way to go.
I've been using some of Farina's FIR filters in a matrix convolution plugin
to perform similar conversions within Reaper. It works rather well for me
and is fairly low latency.
There is a UHJ to Ambix filter here:
On Angelo's site, although he says there that this procedure is outdated:

You first do a UHJ to B-format conversion by using the convolvers,
then use a B-format to speakers decoder VST plugin, of which there are
several

I am currently using Reaper as my DAW. I did a search for Ambsonic VST plug-ins

that The UHJ decoding it could do was from UHJ W,X,Y,Z to stereo and what I am
looking for is UHJ stereo to a speaker feed.
