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. that one of them (11-12) is brought closer to the sound source (A) when the other (12-11) is moved away and vice versa, equally well by either of the two faces of the virtual plane that extends from one to the other, it being possible therefore for the…
