Abstract: A method for generating a sound giving a sensation of depth by applying, after extraction, a transfer function quadrille onto electric sound signals on the left and right thereof. The transfer functions simulate the trajectories taken by the sound associated with the electric signal to be processed in order to reach two receivers, if this sound was emitted in air. The signals that have been processed, one by one, by one of the four transfer functions of the quadrille, are combined with each other, then the sound signal thus obtained is mixed with the original electric sound signal to be processed after a temporal reset.

Abstract: Method intended for the picking up of sounds coming from at least one sound source, for the recording of said sounds and their play-back, by means of a sound pick-up assembly, a recording medium and a transmission assembly. the sound pick-up assembly being composed of at least two microphones, the relative position of which is constant, the recording medium being of any known stereophonic type, particularly with at least two tracks, the transmission assembly comprising at least two members such as earphones, loudspeakers or speaker boxes. It is characterised in that sounds are picked up simultaneously by the two microphones, known as “right” (11) and “left” (12) respectively and that these two microphones (11 and 12) are displaced together with respect to said sound source (A), particularly by causing the distance and/or height of each microphone (11-12) to vary differentially with respect to that source (A), i.e.
