A good way to listen to binaural recordings using speakers is to use a 'stereo dipole' setup; speakers are close together so you see an angle of 15 to 20 degrees between them, and the recording is processed using a crosstalk cancelling convolution matrix. The net result is that each ear only gets the signal from one channel, as with headphones, but you can still move (a little bit) and turn your head w.r.t the sound stage. It works even better with a second pair at the back, using the same signals. The only practical problem is that the 'sweet spot' is quite small. If two persons want to listen at the same time they should be one behind the other, not side by side. The latest release of JACE comes with config and IR files to do this. -- FA Follie! Follie!
