Holophony is the acoustical analogue of holography : given a sound field extending over a large space (like a concert hall) holophony tells us how to reconstruct exactly the part of this field that fills amateur's listening room - i.e. some cubic meters around the best place the connoisseur would have booked in the concert hall. But holophony shows that a high amount of reproducing sources are needed for an ideal acoustic reproductions, so that only A.Moles' myriaphony would meet such a requirement. A simplex approximation is tetraedrophony, which proves rather convenient and agreeable in practice. Some new experiments on auditory perception are also reported, as an account or a legitimation for 3 D-Stereophony.
