This page is being constructed to complement my Binaural,
3D, Holographic Sound page.
One of the problems of binaural recordings, is that they must be played
back over headphones or earphones. This is to insure the left ear gets only
the left ear signal, and the right ear gets only the right ear signal. When
binaural recordings are played over loudspeakers, there is the problem of
cross talk. When the left loudspeaker plays a sound, the listener hears
this in both ears, and similarly for the right loudspeaker, resulting in
garbled 3D. Afterall, if a sound source is moving front to back, or up and
down, you are not going to hear these effects via a conventional stereo
sound system, which is one dimensional (left-right).
One way to make binaural recordings playable over loudspeakers is to preprocess
the signals via a transaural cross-talk cancellation scheme.
One of the most amazing of these systems is the new stereo-dipole
being developed at the Institute
of Sound and Vibration Research and Tokyo
