ML: "Maybe it can; is there a way to "up convert" non-ambisonics recordings to horizontal ambisonics?" If you down sample a 48kHz recording to 16kHz what happens? All the audio information above 8kHz is lost right? If you up convert back to 48kHz can you recover the bandwidth lost? No. You ju

Neil, I used the wrong words. Please excuse my "up-converting" nonsense, and let me ask again. The perceived "directional bandwidth" of stereo recordings is better than what conventional stereo (with cross-talk) can reproduce. So, is it possible to adapt a stereo recording to play on a horizon
