Method and device intended for the picking up of sounds, for their recording and their play-back, and reproducing the natural sensation of a sound space
First Claim
1. A method for picking up sounds coming from at least one sound source for recording and playing back said sounds using a sound pick-up assembly, a recording medium and a transmission assembly, the sound pick-up assembly having at least two microphones, the relative positions of which are constant, the recording medium being stereophonic having at least two tracks, the transmission assembly comprising at least two audio diffusion members, the method comprising:
- picking up sounds from the at least one sound source simultaneously with the at least two microphones;
displacing the at least two microphones together with respect to the at least one sound source concurrently with the picking up sounds;
one of the at least one sound sources being a pre-existing recording, the pre-existing recording being an initial recording;
transmitting sounds from the initial recording using loudspeakers located in a place having acoustic and sound characteristics replicating optimal acoustic and sound characteristics;
making a specific recording of the sounds from the initial recording in the place, said specific recording being influenced by the acoustic and sound characteristics;
subsequently playing back the sounds from the initial recording and the specific recording; and
making a final recording by superimposing the initial recording and specific recording, for later transmission of the final recording.

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 right microphone (11) to become the left microphone (12) and vice versa, it being possible also for the two microphones (11 and 12) to be moved simultaneously closer to and further away from said sound source (A).

4. A device comprising:
-
a sound pick-up assembly for receiving at least one sound source, the sound pick-up assembly having two microphones oriented in opposite directions and held rigidly at a distance from each other approximating a distance between the ears of a person, the sound pick-up assembly having means for displacing and orienting the sound pick-up assembly at any time while picking-up sounds from the at least one sound source in order to present the two microphones to the at least one sound source in any orientation ranging 360°
from one face of a virtual plane parallel to an axis joining the two microphones pointed directly at the at least one sound source;
a recording medium being a stereophonic type and having at least two tracks thereon;
a transmission assembly comprising at least two audio diffusion members; and
a marker on the pick-up assembly for differentiating between the faces of the virtual plane, the marker comprising an asymmetric handle integral with the sound pick-up assembly. - View Dependent Claims (5, 6, 7, 8, 9, 10, 11, 12, 13, 14)

15. A method for processing pre-recorded initial sound signals emanating from at least one sound source using a sound pick-up and transmission assembly, the method comprising:
-
providing the sound pick-up and transmission assembly with left and right microphones;
arranging the sound pick-up and transmission assembly in front of the sound source;
simultaneously picking-up the pre-recorded initial sound signals from the at least one sound source using the left and right microphones;
generating transmitted sound signals corresponding to the picked-up initial sound signals;
superimposing the initial sound signals on the transmitted sound signals; and
diffusing the superimposed signals to produce a specific recording. - View Dependent Claims (16)

17. A method for picking up sounds coming from at least one sound source for recording and playing back said sounds using a sound pick-up assembly, a recording medium and a transmission assembly, the sound pick-up assembly having at least two microphones, the relative positions of which are constant, the recording medium being stereophonic having at least two tracks, the transmission assembly comprising at least two audio diffusion members, the method comprising:
-
picking up sounds from the at least one sound source simultaneously with the at least two microphones, wherein one of the at least one sound sources is a pre-existing recording, the pre-existing recording being an initial recording; and
displacing the at least two microphones together with respect to the at least one sound source;
transmitting sounds from the initial recording using loudspeakers located in a place having acoustic and sound characteristics at least approximately replicating acoustic and sound characteristics existing at the time the initial recording was made;
making a specific recording of the sounds from the initial recording in the place, said specific recording being influenced by the acoustic and sound characteristics;
subsequently playing back the sounds from the initial recording and the specific recording; and
making a final recording by superimposing the initial recording and specific recording, for later transmission of the final recording.
