Ah, right. Not sure I really want to get into building a decoder, wouldn't have thought twice back in the 70's, but don't seem to have the time to do anything nowadays.
Must be an age thing LOL Thanks for your help Richard Hi Richard and Gang It is pretty difficult to see the encoding from the oscilloscope picture as this is an acoustic SFM organ recording. There haven't been any single point sources at any direction in the church, not to mention center front. If you have a center panned mono signal encoded into UHJ center front, it will appear to have that certain phase difference between L and R channels. You can see this with multitrack recordings that have been mixed "Ambisonically". There is a hardware solution to your problem: The Wireless World decoder has settings for 45J and Matrix H. UHJ didn't exist at that time. You just need to build this decoder. The schematics are in the Motherlode: http://decoy.iki.fi/dsound/ambisonic/motherlode/source/Surround%20Sound%20Decoders%20Pts%20567%20WW%201977.pdf Please note that the article is missing the AB/MS stage. You need to pay attention that this design assumes that M = R + L and S = R - L. I once built the WW decoder but I don't have it anymore. But if you just wish to hear the surround soundfield, I would say go and decode with a UHJ decoder. You wouldn't hear the difference. I don't, and I am just a sound designer. :-) Peter's suggestion on converting the recording into G-Format is a good one. Do that. And... as Geoffrey said, don't bother to call Calrec. They'll just get confused. It's great that you have found another missing Ambisonic recording. It isn't listed in the Ambisonic Discography yet: http://members.cox.net/surround/uhjdisc/ambindex.htm > On another point, I feel this record need archiving Absolutely. Funny that there isn't the name of the recording engineer. Usually these LP's had.
