Holophony is in acoustics what holography is in optics. Just as might claim to be the ideal optical illusion, so might claim to be the perfect auditory illusion. As illustration of general principles theoretical basis was obtained by the Bourbakt group, and otherwise by Gabor theory. It is shown that using limited number of secondary Huygens sources one can provide a very presentable auditory illusion imaging the primary sound source.
