and its a great Question Marc ! Let's hope someone has an answer for you that more hopeful than mine. If you could somehow decipher the ILDs and ITDs of your recordings and work out which bits of the wave file correspond to "back left" "back Right" "front left" "front right" and put those out over the corresponding speakers then that could work - if someone knows how to do that a will buy them a beer at the next conference.
