Definitions

  • Sound recording is done by at least two microphones fixed in one position and one specific orientation and considered as "strategic" in relation to the source of his.
  • the sounds coming from one of these two microphones, or from a set of microphones, are recorded on a track while sounds from the second microphone, or the second set of microphones, are recorded on another track, separate from the first.
  • the recorded sounds are reproduced by at least two loudspeakers (or speakers) suitably placed and oriented.
  • any stereophonic system comes from the transposition to the sounds of the stereoscopy, first in date, itself based on the binocular vision of Man.
  • the holograms, the bipolarized images or anaglyphs for example reproduce the relief quite well visual (at the cost of many artifices, moreover), it is not the same for systems stereophonic, by the very fact of their simplicity which would like that in a natural way, Man hears all the sounds of space from only two sources. In other words, all complex sounds distributed in a space of three dimensions, including different levels, are reduced to the single plane which brings together the loudspeakers and at their only level.
  • stereophony contains its own limits by the simple fact that it reduces the number of sound sources to two offered to listen to the listener, themselves subject to the track limit without any possibility of a third dimension.
  • the present invention relates to a process different from those known, based on the diffusion of very realistic sounds, that is to say close to reality, which supposes in particularly a strong "relief” and the presence of ambient sounds, corresponding to conditions of reality.
  • the invention thus makes it possible to reconstitute, when listening, a space three-dimensional sound, including vertical levels and front and rear spaces compared to the listener.
  • Figure 1 is a schematic view illustrating the method and the device according to the invention, according to a very simple embodiment.
  • Figure 2 is a schematic view illustrating one of the many possible phases of the method, according to the same embodiment of the device as that of FIG. 1.
  • Figure 3 is a schematic view of a more elaborate embodiment of the device according to the invention.
  • Figures 4 to 6 are schematic views illustrating a manipulation of a device according to the method of the invention, for the variable recording of a fixed sound source.
  • Figures 7 to 9 are schematic views similar to Figures 4 to 6, illustrating a other manipulation of the same device according to the method of the invention, for recording the same fixed sound source.
  • Figures 10 to 12 are schematic views illustrating, for a stationary listener, the variable sound impressions he perceives according to the positions of the device of Figures 4 to 6.
  • Figures 13 to 15 are schematic views illustrating, for a stationary listener, the variable sound impressions he perceives according to the positions of the device of Figures 7 to 9.
  • Figure 16 is a schematic view illustrating a sound recording on the spot according to the invention.
  • FIG 17 is a schematic view illustrating a feature of the invention which includes a recording of sounds emitted by energy radiating devices acoustics in the surrounding space, namely here loudspeakers.
  • Stereophony can only concern a plurality of sound sources or a distribution significant spatial.
  • the recording of a symphonic orchestra on two tracks and the playback of the recordings of the two tracks by two speakers or two headphones would not really be of interest in itself if this stereophony did not constitute a powerful stimulus from the human brain that artificially reconstructs for the listener, by unconscious analogy of memorized memories, the atmosphere of a concert hall in which he attributes a depth and a width. Otherwise, the auditor would be content to hear the violins on the left and the double basses on the right, the other instruments distributing partially left and right, without any relief.
  • This defect is inherent in stereophony and is particularly felt when the broadcasting takes place in a performance hall, in particular a cinema, when has speakers not only at the front, screen side, but also at the back of the room.
  • the aim is to best give a feeling of sound space to the spectators by distributing the sounds so that the sound perception of a movement suggested in the image is as realistic as possible.
  • the fixity of the microphones, the fixity of the sound sources and the fixity of the speakers acoustic have the effect of freezing all the sounds in an illusory volume because no difference in sound is perceived in relation to the pitch.
  • the finished film includes a "picture tape” filmed live and a "soundtrack” formed by the superimposition of the original sounds including mediocrity, or even the absence, is compensated by the re recording in the studio.
  • the invention proposes a new recording method which makes it possible to really create not a simple finished volume but a three-dimensional sound space immediately perceptible by a listener, transversely (from - ⁇ on the left to + ⁇ on the right via the immediate proximity), vertically (from bottom to top and vice versa), longitudinally (from - ⁇ behind the listener to + ⁇ in front of the listener via immediate proximity).
  • the invention makes it possible to make particularly lively recordings in providing listening conditions extremely close to what they should have been on site during check-in.
  • the sound recording device is specific and the process is completely different from current processes since we can even show that it is contrary to all known recommendations.
  • the recorded sounds are reproduced using headphones or speakers depending on listening conditions: in private, in public, from a disc, from a tape sound of a film, etc.
  • a device in its simplest form. It includes an autonomous set of sound recording 10 formed of two microphones 11 and 12 rigidly joined by a rod 13 whose length is close to the straight line distance between the two ears of a common human being and who carries a plane longitudinal screen 14 having the best soundproofing qualities possible to best individualize the two microphones 11 and 12.
  • the set 10 is integral with an operating handle 15 because it has no fixing member or immobilization.
  • An electric cable 16 containing specific conductors for each of the two microphones 11 and 12 brings together the assembly 10 and a recording device 20 of any known type capable of differentiating the signals from microphones 11 and 12.
  • we have schematized an assembly allowing the use of a cassette 21 symbolizing everything recording medium.
  • the cassette 21 is then used as usual by reading in a recording device.
  • sound reproduction 30 to which a headset 40 fitted with two headphones 41 and 42 is connected by a cable of any known type 43 containing conductors specific to each of the headphones 41 and 42.
  • the set 1 is manipulated by a user from the position shown in the upper right of figure 1.
  • the user can rotate, more or less quickly, the assembly 10 roughly along the axis of the handle 15, from the orientation drawn in solid line in the dashed orientation, as evoked by the double arrow F1.
  • the microphone 11 is closer to the source A than the microphone 12 in an orientation and further away in the reverse orientation.
  • the microphone 11 will remain the farthest two microphones compared to source A but the sound collected by microphone 12 will go first by increasing then decreasing.
  • the set 10 will be at the source A source, that is to say when the flat screen 14 almost completely hides the microphone 11, the sound reaching the microphone 12 will be clearly predominant and a small residual part of the sound original will be picked up by the microphone 11.
  • FIG. 2 the possible movement of the assembly 10 has been shown above the source A, from a position of proximity at the bottom left to a position distant at the top right of this figure without change of orientation, which corresponds to a constant relative position of the two microphones 11 and 12 relative to the source A, unlike the example in Figure 1.
  • each microphone corresponds to one of the earphones 41 and 42.
  • the microphone 11 considered to be the right microphone corresponds to earphone 41
  • microphone 12 considered to be left corresponds to earpiece 42.
  • FIG. 3 there is shown a more elaborate embodiment of the device which, here, comprises in addition to the plane longitudinal screen 14, a plane transverse screen 17 which extends from one microphone to the other, in order to determine a sonic space in front of microphones 11 and 12 and a sonic space behind said microphones 11 and 12 because these, supported by the longitudinal screen 14 only differentiate the right and left lateral spaces.
  • This device provided with the same handle 15 as that of FIGS. 1 and 2, can be manipulated as already mentioned but, here, the movements of the assembly 10 make it possible to clearly differentiate the pre-eminence of the front sounds compared to the rear sounds and vice versa.
  • the invention makes it possible to produce the longitudinal and transverse screens respectively in merging them into a sphere made of phonically insulating material because the laterality is marked by the insulating mass of the sphere considered transversely and the front - rear differentiation comes from the insulating mass of the sphere considered longitudinally.
  • This spherical assembly 50 must be devoid of any fixing member, unlike known devices, and the mobility to which it must be subjected, requires the user to have a means of identification front - rear and / or right - left.
  • the assembly 50 Since, in addition, the assembly 50 must have an operating handle 15, it is advantageous to concretize the front - rear location (from which it automatically results the correct positioning right - left of microphones 11 and 12) by giving the handle 15 an asymmetrical profile constituting a polarizer avoiding a reverse orientation of the one you want.
  • the handle 15 is provided with a sheath 18 which is smooth at the back and crenellated at the front.
  • the microphone 12 is closest to the source A and therefore receives a flux maximum sonic, while the microphone 11 is exactly opposite source A and does not receives only residual sounds, notably due to echoes.
  • microphones 11 and 12 are equidistant from source A and receive the same flux.
  • the microphone 11 is closest to the source A and therefore receives a flux maximum sonic, while microphone 12 is exactly opposite source A and does not receives only residual sounds, notably due to echoes. This orientation is therefore exactly symmetrical to that of figure 4.
  • Figures 7 to 9 are similar to Figures 4 to 6, but the assembly 10, if it rotates well always in the direction of the arrows F3, has a starting position in which the microphone closest to source A is microphone 11.
  • the arrows symbolize the sounds according to the direction that the listener perceives but it is obviously impossible, on the plan of a sheet of paper, to represent the three dimensions of space.
  • the listener hears sounds distributed from right to left, according to a front panoramic distribution, corresponding to the symmetrical orientation of the microphones 11 and 12 of FIG. 5, the virtual transverse plane of the assembly 10 having its front face arranged towards source A.
  • the listener perceives sounds that move from left to right, substantially at constant pitch and whose feeling of proximity remains unchanged.
  • Figure 16 there is shown an example of sound recording by means of a set 50, which is manipulated around the head of a panting dog, the listener then listening this taking of sounds, having the impression that the dog turns on itself and, according to movements of the assembly 50, moves away and approaches.
  • the sound source is a musical instrument
  • a magnetic tape broadcast by an acoustic enclosure can be re-recorded then placed in a different, artificial sonic space.
  • the displacement of the whole assembly and the microphones it carries makes it possible to vary differentially the distance, in all directions of space, of each micro with respect to the source and to present to this source, one of the two faces of the plane transversal virtual.
  • the method of the invention can be used with several sound sources and no longer just one and when you record, for example, a symphony orchestra or a large jazz band, it is possible to make effects equivalent to those of zoom in optics, namely that without modifying the musical performance in any way, we can favor this or that instrument or one part of the orchestra over another.
  • After having made particular recordings we collect them freely, as the user wishes, on two recording tracks, in order to group the right and left recordings which will be assigned, when listening, either to the listener right, or to the left earpiece.
  • FIG. 17 we see a particular application of the invention which is illustrated by an example first of all providing sound recording studio 60, including a microphone 61 of any known type and which we have chosen here as being of monophonic type.
  • the microphone 61 is connected by a conducting cable 62 to a recording device 63 which is here symbolized by a cassette recorder.
  • the recorded cassette 64 therefore contains a so-called "initial” recording which can be qualify as "flat” because the sound recording in studio 60 was done in silence.
  • the recording therefore only concerns words spoken in front of the microphone 61 or that music isolated from any atmosphere.
  • the cassette 64 is placed in a reading device 65, as evoked by the arrow F4, connected to two speakers 66 and 67, the whole being located in a location 70 separate from the recording studio 60.
  • the sounds broadcast by the signals are captured and then recorded.
  • pregnant 66 and 67 contrary to all universally accepted principles that leave of the observation that the quality of the sounds collected is degraded by the characteristics of the reader, its vibrations and its imperfections, without counting the defects of the support recording noise or extraneous noise existing in the place where this is done recording.
  • the invention makes it possible, from this initial recording, to obtain a recording so-called "specific" stereophonic by means of a set 50, in a large room, such as a concert or performance hall, so that the specific recording adds to the orchestra the atmosphere and the reverberations of the room, the whole being enriched by the conditions for taking sounds specific to the invention.
  • the assembly 50 is connected by a conductor 71 to a recording device stereophonic 73 by which one obtains a specific recording on a support that we have schematized here by a cassette 74.
  • a room 75 which can be a studio, we place the recording medium initial 64 in a reader 76 (arrow F6) and the specific recording medium 74 in a reader 77 (arrow F7), both connected to a recording device 78 by conductors 79 and 80.
  • This recording device can obviously be optimized by specific means such as multitrack recording devices, software using the so-called “D t D” technology, abbreviation of " D irect t o D isk”, etc.
  • This recording medium constitutes, after the specific processing of mastering, the master from which one can make as many copies as there is required, copies for commercial distribution.
  • cassettes which have been represented in FIG. 17 can, in the reality, being recording media of all kinds, including soundtracks motion picture films or video cassettes.
  • These recording media are intended for reading devices themselves any known type, associated with transducers such as headphones or speakers.
  • enclosures arranged as explained higher: near the screen, on the sides and at the back of the room constitute a whole with performances unknown to date, in particular by the fact that the sound recording according to the invention makes it possible to restore a "sliding sound" when listening completely eliminating the sound hole effect, so it is now possible to circulate sounds from speaker to speaker without any discontinuity and, by Consequently, the use of multiple speakers is no longer reserved for the reproduction of fast, dazzling sounds, but also to slower sounds, such as the steps of a character approaching or moving away.
  • the listener at his home listens to an orchestra as if he were alone in the concert hall, with the whole feeling of space and realism, but without the disadvantages of a large audience: repeated coughing, unwanted applause, etc.
  • the sound levels of players 76 and 77 are adjusted so that the sound level of the initial recording is at a level that we consider as a reference level, while the sound level of the recording specific can evolve on either side of the reference level.
  • the sound level of the recording specific ranges from - 5 to + 5, depending on the specific spatialization effect that we wish to obtain.
