The invention relates to acoustics, namely, stereo equipment, and can be used to ensure the reality of spatial sound reproduction using headphones head is the destination, containing earphone headset, the set of stereo headphones, a stand-alone token rotation direction of the head of the listener and a feedback circuit connecting the output of the marker direction with the control input of the processing unit stereo [1,2]
A disadvantage of the known devices is the dependence of reality (and/or the inadequacy of the psychological perception of the parameters of the reproduced acoustic space) from changes in head position and movements of the listener.The closest in technical essence to the offer relates stereo system  was adopted for the prototype.The prototype contains headphones headset and connected output processing unit stereo, controlled input connected to the output of the Autonomous marker direction.In the well-known stereo left and right audio signals are fed through a delay line to the adders. This mimics increase the stereo width and extends subjective acoustic space. The degree of signal delay in each delay line is controlled by a signal from a stand-alone marker direction (azimuth) head of the listener. As a token napravite contradiction, occur when playing with headphones parameters of the acoustic space, the coordinates of which the applicant relates exclusively to the geographical azimuth, with the localization of the speakers at the listener's head. That is, for any change in the torso required preset (correction) "O" marker direction relative to the front-straight torso and head of the listener.The technical result from implementation of the invention is to increase the reality of the reproduced acoustic space by matching the origin of the reproduced acoustic space and internal (mental) model of this space with the level of reference, which is "the body schema, and adequate correlation information about the spatial characteristics of the audio signals by changing the position of this element "the body schema". 
This technical result is achieved due to the fact that in the known stereo, containing headphones headset and connected output processing unit stereo, controlled input connected to the output of the Autonomous marker directions, Autonomous macroplan on the power generation stereo, located on the torso of the listener, and the identical receiving antenna vibrators on each one of headphone headset with directional antenna vibrators form between them a right angle.In addition, the stereo system further comprises situated on the earphones or head two-dimensional sensor of angular position of the headphones (the head) in the vertical plane, made in the form of inertial mass, is fixed in a vertical plane, and two differential transducers its spatial position, the outputs are connected to a managed unit forming a stereo effect.In the particular case of the inertial mass is made in the form of optically transparent frosted globe, mounted on a flexible vertical light guide, and two differential transducer made in the form of two pairs of sensors installed in the horizontal plane in orthogonal coordinates, and the light source, optical coherent through a flexible light guide and frosted ball with two pairs of photodetectors.In addition, the stereo system further comprises a multi-input a / d Converter and a microprocessor, and a controlled entrance statementany converters spatial position of the inertial mass connected in series through multiple-input ADC and microprocessor.In the particular case of a stereo system may contain additional DAC, the input connected to the output of the microprocessor, and the output from the modulating input light source two-coordinate of the sensor of angular position of the headphones.In Fig.1-3 are examples of how to perform an offline token directions at different positions of the head of the listener; Fig.4 is an example of executing a sensor of angular position of the Jack in a vertical plane; Fig.5 block diagram of the stereo.The stereo system includes a head phone 1 and the offline token should be made in the form of angular navigation device, the radiation source 2 which is fixed to the forming unit stereo effect 3, and identical antenna vibrators 4, 5 on each one of the headphones 6, 7 of the head 1 (Fig.1-3).There is also a two-dimensional sensor 8 angular position of the headphones 6, 7 in the vertical plane, located on the earphones or head and made in the form of inertial mass (for example, in the form of optically transparent frosted globe 9 (Fig.4), mounted on a flexible light guide 10) fixed in the vertical plane and two differential converters her space the barb on the orthogonal coordinates X and Y, and a light source 15, optical coherent through a flexible light guide 10 and frosted ball 9 with a photodetector 11.14), the outputs are connected to a managed unit forming a stereo effect.The directional antenna vibrators 4,5 form between them a direct goal, as conventionally shown in Fig.1,2 (position 16 marked the head of the listener). This allows to unambiguously determine the position of the head (phones) relative to the radiation source attached to the torso, in the horizontal plane.The device forming unit stereo 3 coincides with the prototype or the function is handled by the processor. In this case, the block 3 includes two delay lines 17, 18, two adder 19, 20, delay lines 21, 22, two of the attenuator 23, 24 and two adder 27, 28. Electrical connections are presented in the prototype and in Fig.5.A stereo may also optionally contain multi-input ADC 29, the microprocessor 30 and the DAC 31, functional wiring diagram of which is shown in Fig.5.According to PP. 1, 2 and 3 claims managed entrance 32 of the processing unit stereo 3 is connected directly to the outputs (2,4,5) Autonomous marker direction and two differential the p. but 4 claims data communications are carried out through serially connected multi-input ADC 29 and the microprocessor 30, i.e. according to the applicant, p. 4 does not violate the unity of invention, since the previous communication on the PP.1-3 essentially remained in the device.The stereo system works as follows.When determining the control parameters of the delay lines in the headphones 6, 7, you receive the stereo effect, is equivalent to the fact that could experience the listener, if used stationary stereo button front with a particular stereo image. While the attenuators 23, 24 must create the weakening of signals and filters 25, 26 need to simulate the difference in the spectrum of perceived auditory system depending on the distance to the sound source and the transfer function of the head. Turning the head of the listener 16 to the right or left, up or down relative to the body does not distort the reality of the perception of the reproduced acoustic space, and appropriately modulates the dependent variables, as controlled entrance 32 of the processing unit stereo 3 serves appropriate control signals from the marker direction (2,4, 5) and a sensor of angular position 8 newsnote perception of sound, distributed in reproducible three-dimensional space.If the composition of the multi-input stereo DAC 29 and the microprocessor 30 simplifies the management of weighting factors dependent variable processing unit stereo 3 input 32. Adding in the composition of stereo DAC 31 and the modulation of the light source 15 of the sensor of angular position 2 allows you to extend the capabilities of the reproduction and use of stereo in computer games and to implement special musical effects, which is set in the application technical result.Sources of information taken into account in the preparation of application materials

SUBSTANCE: invention concerns mixing of acoustical signals and, more particularly, to mixing or mixing with depression of two or more sound channels with use of the correlated output data. The result is reached because mixing is carried out between any two or a considerable quantity of input channels by means of processing of sound channels for forming of one or more "correlated" acoustical signals for each pair of input channels. The inphase correlated signal representing contents which is identical in both channels or very similar, with a small time delay on a phase or on time, mix with entrance channels. The correlated signal not coinciding on a phase (identical or similar signals with an appreciable time delay on a phase or on time) usually rejected also by a pair of independent signals (signals which are not present at other input channels) which can be mixed with input channels, can be also formed using the presented way.
EFFECT: sound channels mixing without input of undesirable disturbations or excessive deterioration of discrete representation of an initial sound.
