That was mine. There are several demo tracks on the Ambiophonic website that you can download. But you should get the free Apple/Android(not free) Ambiophonic app or the free Hotto Transcoder and play your own favorite recordings via good speakers. Angelo Farina and others on the Sursound list know all about this and have contributed to advancing this technology.

Unless I am completely mixing this up with some other system, I recall some demo soundfile you posted some while back (must have been via sursound) using two adjacent speakers, and getting a quasi-surround/widening effect. I recall it particularly, because just using my two toy Apple speakers either side of a round iMac (so hardly a definitive or rigorous test!) I actually got the effect quite clearly. If that was not yours, whose might it have been?
