Hi all huge thanks for all your comments, the conversation developed in various different directions but there were quite inspiring ideas, at least for me. Particularly I found quite interesting the discussion on decorrelation, and I loved the trick of re-recording a sound with a loudspeaker and a stereo pair.
Richard, I agree, I would also expect Gerhard to have a specific meaning in mind, something he would have bumped into somewhere. He was just starting to get familiar with stereophony, perhaps he was just thinking of MS image control or reverberation... I don't discard something in direction of the PS22 either. Does anyone know if this process could have been common in the mid 60s BBC to 'upgrade' mono recordings? Just thinking aloud, another trail might be american experimental music, i.e. some spatialisation gadget that e.g. someone like gordon mumma could have put together and Gerhard became familiar with during his visits to the EEUU. He was a curious man. I'm not sure I understand what you mean by primary and environmental sound though...
