Wrong topic?
I have a question concerning the conversion of a stereo recording to
ambisonics. In the Wireless World of 1977 articles there are equations for
the
conversion of stereo to W,X,Y equivalent signals. The use of j*Diff term
doesn't seem to make sense.
This is the other direction...
You can't make naive predictions on what ambi stereo decode will sound like
that; especially when you have j terms. You have to apply the full General
Metatheory ...

Hi All
For those who don't know the Wireless World decoder articles,
they are in Sampo's Motherlode:

There is also a list of corrected component values at the end of the pdf.

I know nothing about the mathematics, and possiby this has nothing
to do with your problem, but I want to make a note about the decoder

Hi,
The person to really answer this is Geoffrey barton (or perhaps
Peter Craven). I'm sure I have something on this somewhere (possible
in the stuff that went to the FCC??) but I can't find it at present.
I'll have a think about this, but it may have been something to do
with improving on the e

I have not had a chance to look at this in detail,
but one point seems worth noting in advance:
Such a conversion is in the literal sense
impossible. Stereo is a system with two
"degrees of freedom". Horizontal Ambisonics
has three. One can Ambisonics into stereo
