Description

[0001] The invention relates to the individualization and marking of audio information, namely, to the application of a mark to audio information placed on a magnetic tape, the subsequent identification of the mark and the detection of an unauthorized digital copy of the audio information on the Internet.

[0002] This topic is especially relevant when labeling magnetic tapes containing important information, such as the album master tape of a music label or other copyright holder. The album master tape and its several backup copies, usually two or three, are almost always stored in the copyright holder's archive, and access to them is strictly limited. Access to backup copies of the album master tape usually arises when the album is reissued on physical media, such as vinyl or CD, or when the album is released digitally. The sound engineer works with the backup copy of the album master tape to prepare a production copy of the album master tape, taking into account the technical requirements of the media format. In any case, preparing a production copy of the album master tape results in a deterioration in the album's sound compared to the copy of the album master tape. A direct copy to magnetic tape from a backup copy of the album master tape implies minimal loss of sound quality.When preparing a physical reissue of an album, the number of copies of the planned print run is agreed upon in advance. However, subsequent unauthorized copying from one magnetic tape to another is impossible to track. These factors have led copyright holders to impose an unspoken ban on direct copying from a backup copy of an album's master tape to another magnetic tape. They are unwilling to either distribute albums themselves or license direct copying rights to third-party record labels. Therefore, there are no official magnetic tape releases produced by directly copying from a backup copy of an album's master tape to another magnetic tape. Therefore, labeling the magnetic tape to enable subsequent identification and detection of unauthorized digital copies of a musical composition online would solve this problem.

[0003] A known "Identification Tag" (see Patent Application No. 2002125927, published on May 20, 2004) comprises a core made of a magnetic material, a capacitance, an inductance, and a frequency control element. The core is made of an amorphous soft magnetic alloy, the capacitance is formed by the surface of the soft magnetic material, a dielectric layer applied to the surface of the soft magnetic material, and the surface of a conductive material layer applied to the dielectric layer, while the inductance is formed by a layer of conductive material, the frequency control element is made of a hard magnetic material and is mounted so as to be capable of electromagnetic interaction with the core made of soft magnetic material.

[0004] The disadvantages of the known identification mark include the impossibility of placing it on magnetic tape.

[0005] Another technical solution, taken as a prototype, is known - "Marking of data carriers intended for reproduction," Russian Federation Patent No. 2329552 dated July 20, 2008, Bulletin No. 20. A method for marking a machine-readable medium containing data stored on the medium in a continuous sequence and intended for reproduction. In the area of ​​​​the data intended for reproduction, a sequence of marks is made individualizing the medium, in analog or digital form, read along with the data intended for reproduction. The sequence of marks has the function of marking, characterizing the medium, and represents an identification code: a binary code or a barcode. In the case of a binary code, individual marks in the sequence of marks are deliberately included or omitted. Thus, a binary code is determined by the presence and absence of individual marks. A barcode is understood to be a sequence of marks of varying thickness, i.e., different elongation.The invention also provides for the possibility of applying other types of markings to the medium, encoding useful information using a sequence of marks. A specific example of applying a sequence of marks forms a binary code. In the specific embodiment under consideration, the sequence of marks encodes the binary number 1110101, corresponding to the decimal number 117. Such sequences of marks are suitable for use as individualizing markings on magnetic tape. Thus, when playing a magnetic tape, this sequence of marks is read from the tape during the reading process of the data intended for playback, which allows the presence of an individualizing marking on the magnetic tape to be recognized during playback.The geometric dimensions of the marks, as well as the degree of change in the tape's magnetic properties in the area of ​​these marks, are determined so that their presence does not distort, or only slightly distorts, the human perception of the reproduced information. Conventional reading devices may be used to read the data intended for reproduction and the marks associated with it. The marks may be implemented on the media in such a way as not to interfere with the perception of the reproduced data by viewers or listeners, or in such a way that such interference is barely noticeable.

[0006] The disadvantages of the existing technical solution include the limited technological capabilities of the proposed labeling system, which uses a set of marks. This is due to the limited amount of encoded information related only to magnetic tape identification and the low quality of their application, which does not fully ensure the high-quality sound of the intended musical compositions. Other disadvantages include limited functionality due to the inability to subsequently detect an unauthorized digital copy of a musical composition online. Moreover, this labeling method does not guarantee the absence of distortions—the authors themselves state that applying a sequence of marks can only introduce minor distortions.Thus, the known method of marking is not suitable for marking magnetic tape tracks with important information, for example, a copy of a master tape with reference sound quality of musical compositions, and since the owners of licensed copies of albums are not protected in any way from unauthorized copying of the copies they made from a licensed copy of the album (from a master tape), the method finds no application in this area.

[0007] The technical result of the proposed invention is to eliminate the deficiencies of its analogue and prototype, namely, to expand the technological and functional capabilities of labeling musical compositions on magnetic tape. This is achieved by improving the label's quality while maintaining the sound quality of the musical composition and increasing the volume of encoded information applied to the magnetic tape; enabling subsequent identification and detection of unauthorized digital copies of musical compositions on the Internet. This also ensures the accessible and widespread application of the proposed method.

[0008] The technical result achieved is achieved by using a combination of known features common with the prototype, including the application of at least one mark in the form of an analog signal read together with the musical composition intended for reproduction and new features consisting in the fact that the mark is pre-generated in the frequency range between 13,000-50,000 Hz - in the form of a continuous analog signal of arbitrary duration and / or in the frequency range from 5 to 50,000 Hz - in the form of a sequence of short analog signals of arbitrary duration, by encoding information using a specially developed program installed on the computer of the owner of a licensed copy of the album or an interested person, or placed in the personal account of the cloud service on the Internet provided to him, then the generated mark is applied to the main signal in any place of at least one musical composition of the magnetic tape,excluding the mutual overlap of tags - for this purpose, connect the sound card of the computer on which the tag generation program is installed and / or through the personal account of the cloud service on the Internet, where the tag generation program is installed, to the audio system, for example, through a mixing console, while the input signal level from the two sources: the sound card and the main signal are set to be both the same and different, but not more than +9 dB, after which they ensure the detection of at least one tag on the Internet on digital copies of the musical composition using the developed agent program, located on the computer or in the personal account of the cloud service on the Internet; each generated searched tag, a list of checked musical albums and compositions are preliminarily entered into the agent program,If at least one label is detected, the agent program identifies it and sends information about the detection of an unauthorized digital copy of a musical composition to the owner of a licensed copy of the album and / or an interested party with a link to the Internet resource where the label was detected on the unauthorized digital copy; in this case, each owner of a licensed copy of the album or an interested party - on a computer or in a personal account of a cloud service on the Internet, preliminarily creates their own catalog of publications with an individual code for each customer of a copy of the magnetic tape, on the basis of which all subsequent labels are generated.

[0009] When generating a tag, the information necessary for its subsequent identification is encoded, such as:

[0010] - name of the owner of the licensed copy of the album or the interested party;

[0011] - album catalog number from the publication catalog;

[0012] - serial number of the circulation;

[0013] - number of copies in the print run / copy number from the print run;

[0014] - order number for recording a copy;

[0015] - date of recording the copy;

[0016] - name of the owner of the magnetic tape copy.

[0017] The interested party is the owner of the record label and / or the copyright owner and / or the performer.

[0018] The agent program automatically monitors Internet resources where digital music files are posted around the clock.

[0019] The agent program sends information about the found tag to the owner of the licensed copy of the album and / or the interested party, and / or the owner of the magnetic tape copy immediately with a decryption of the encoded information used to generate the tag.

[0020] The generation of a tag is started on the computer of the owner of a licensed copy of the album or an interested party, on which the tag generation program is installed and / or through the personal account of the cloud service on the Internet, where the tag generation program is installed.

[0021] The mark is applied sequentially with or without an interval between marks.

[0022] Detection of tags is carried out using a developed AI-agent program located on a computer or in a cloud service on the Internet, while the AI-agent program is pre-trained on each generated search tag and a list of checked musical compositions.

[0023] The novelty of the proposed invention is that the mark is pre-generated in the frequency range between 13,000-50,000 Hz - in the form of a continuous analog signal of arbitrary duration and / or in the frequency range from 5 to 50,000 Hz - in the form of a sequence of short analog signals of arbitrary duration, by encoding information using a specially developed program installed on the computer of the owner of a licensed copy of the album or an interested person, or placed in the personal account of the cloud service on the Internet provided to him, then the generated mark is superimposed on the main signal at any place of at least one musical composition of the magnetic tape, excluding the mutual superposition of marks - for this, the sound card of the computer on which the mark generation program is installed and / or through the personal account of the cloud service on the Internet, where the mark generation program is installed, is connected to the audio system, for example,via a mixing console, with the input signal level from two sources: the sound card and the main signal, set to be either the same or different, but no more than +9 dB, after which at least one tag is detected on the Internet on digital copies of the musical composition using a developed agent program located on a computer or in a personal account of a cloud service on the Internet; each generated search tag, a list of checked music albums and musical compositions are entered into the agent program in advance; if at least one tag is detected, the agent program identifies it and sends information about the detection of an unauthorized digital copy of the musical composition to the owner of a licensed copy of the album and / or an interested party,and / or the owner of the magnetic tape copy with a link to the Internet resource where the label on the unauthorized digital copy was found; in this case, each owner of a licensed copy of the album or an interested party - on a computer or in a personal account of a cloud service on the Internet, preliminarily creates their own catalog of publications with an individual code for each customer of the magnetic tape copy, on the basis of which all subsequent labels are generated.

[0024] Thus, the feature of preliminary generation of a cue in the frequency range between 13,000-50,000 Hz – in the form of a continuous analog signal of arbitrary duration and / or in the frequency range from 5 to 50,000 Hz – in the form of a sequence of short analog signals of arbitrary duration, ensures an increase in the quality of the cue, since the generation of a cue in the specified range does not affect the sound of the copy of the musical composition made from the magnetic tape of the owner of the licensed copy of the album, otherwise known as the master tape, and will ensure the playback of the musical composition located on the magnetic tape played together with the cue, with the preservation of the sound quality. Since a person typically hears sounds in the frequency range from 15 to 13,000 Hz, generating a cue in the form of a continuous analog signal of arbitrary duration in the range of less than 13,000 Hz is no longer practical, since this can negatively affect the quality of the reproduced musical composition.Generating a signal in the frequency range of 5 to 50,000 Hz places it within the human audible range, and therefore, to preserve sound quality, it is generated as a sequence of short analog signals of arbitrary duration. Generating a signal in the range above 50,000 Hz is impractical, as it requires more sensitive and expensive equipment and will not affect the signal's quality.

[0025] The arbitrary duration of the mark depends on the playing time of each musical composition it marks, since the mark can be made either short or of a duration not exceeding the playing time of the musical composition it marks.

[0026] At the same time, the mark generated in the frequency range between 13000-50000 Hz - in the form of a continuous analog signal of arbitrary duration, can be detected both with the help of a developed agent program located on a computer or in a personal account of a cloud service on the Internet, and with the help of special equipment or a program, for example, the iZotope sound editor - which is an additional warning measure and a reminder to unscrupulous competitors that a copy of this musical composition was made under license, that it is marked and its unauthorized copying is illegal.

[0027] Since the tag, generated in the frequency range from 5 to 50,000 Hz, is generated as a sequence of short analog signals of arbitrary duration, it can only be detected using a developed agent program located on a computer or in a personal account on a cloud service online. To detect the tag, it is necessary to know its generation algorithm, which is provided only by the agent program, since each generated target tag is pre-populated. Since the tag is generated as a sequence of short analog signals, it is virtually impossible for third parties to detect it. This provides an additional security measure in case the tag, generated in the frequency range between 13,000 and 50,000 Hz—as a continuous analog signal of arbitrary duration—was not applied or if individuals seeking an unauthorized copy attempted to remove it.

[0028] The feature of generating a mark in the form of a sequence of short analog signals of arbitrary duration makes it possible to apply it in the frequency range audible to humans.

[0029] The feature that the label is generated by encoding information using a specially developed program installed on the computer of the owner of a licensed copy of the album or an interested party, or placed in the personal account of the cloud service on the Internet provided to him, ensures the expansion of the technological and functional capabilities of labeling musical compositions on magnetic tape, associated with an increase in the quality of the label and an increase in the volume of encoded information applied to the magnetic tape necessary for the subsequent identification of the label by the agent program, and also ensures the possibility of accessible and widespread use of the proposed method of labeling a musical composition on magnetic tape and the subsequent detection of an unauthorized digital copy of this musical composition on the Internet.

[0030] The feature of superimposing a generated mark on the main signal anywhere on at least one musical composition on magnetic tape, eliminating overlapping marks, enables subsequent identification of marks even on a single musical composition. Moreover, unlike the prototype, which marks a machine-readable medium containing data stored on the medium in a continuous sequence, the purpose of applying the proposed mark is not simply to mark the medium, but to specifically mark the musical composition on magnetic tape, ensuring the subsequent identification of this mark and the detection of unauthorized digital copies of this musical composition on the internet. Overlapping marks will complicate identification.

[0031] Connecting the sound card of the computer on which the tag generation program is installed and / or connecting it to the audio system, for example, via a mixing console, through a personal account on the cloud service where the tag generation program is installed, expands the functionality of tagging musical compositions on magnetic tape. Furthermore, the presence of specialized equipment, such as a mixing console, allows for the tag to be applied both simultaneously with the recording of a musical composition and separately when copying an existing recording of a musical composition.The fact that the label can be applied through a personal account in a cloud service on the Internet additionally provides the opportunity for a wide range of individuals to acquire rights and use the proposed invention for their own needs, and also ensures the legality of the legal relationship between the patent holder for the proposed invention and the copyright holder or author of the audio work released into civil circulation.

[0032] This flag indicates that the input signal level from the two sources—the sound card and the main signal—is set to either the same or different, but no more than +9 dB. This ensures improved cue placement and high-quality sound for the music being played. Setting the signal above +9 dB will introduce distortion, which will negatively impact the recording of a licensed album copy from magnetic tape.

[0033] Detection of at least one online tag on digital copies of a musical composition using a developed agent program hosted on a computer or in a personal account on a cloud service enables subsequent detection of an unauthorized digital copy of a musical composition online. Since the owner of a licensed copy of an album or an interested party intends to produce and tag copies of the licensed copy of the album (master tape) only on physical media, the mere presence of a digital copy of a musical composition with a tag online will indicate that it is an illegal, unauthorized copy.

[0034] The addition of each pre-generated search tag, a list of scanned music albums and compositions, to the agent program, and the ability to identify and send information about the tag to the owner of the licensed album copy and / or the interested party, and / or the owner of the magnetic tape copy, along with a link to the internet resource where the tag was found on the unauthorized digital copy. This feature expands the technological and functional capabilities of labeling musical compositions on magnetic tape, as well as the subsequent detection of unauthorized digital copies of musical compositions on the internet.

[0035] The requirement that each owner of a licensed copy of an album or interested party pre-creates their own catalog of releases—either on a computer or in their personal cloud service account—with a unique code for each magnetic tape copy customer, which is used to generate all subsequent tags. This ensures the detection of unauthorized digital copies of any of these releases. This will also ensure the widespread applicability of the proposed method, as owners of licensed copies of albums or interested parties will be able to track infringements of their intellectual property rights when independently reproducing licensed albums and when licensing the right to directly copy onto magnetic tape to third-party record companies.

[0036] An indication that when generating a tag, the information necessary for its identification is encoded, such as:

[0037] - name of the owner of the licensed copy of the album or the interested party;

[0038] - album catalog number from the publication catalog;

[0039] - serial number of the circulation;

[0040] - number of copies in the print run / copy number from the print run;

[0041] - order number for recording a copy;

[0042] - date of recording the copy;

[0043] - the name of the owner of the magnetic tape copy, as well as the indication that the interested party is the owner of the recording company and / or the copyright owner, and / or the performer - facilitates the possibility of subsequent identification of the label, the formation of more complete and accurate information not only about the copyright holder of the magnetic tape and the number of its copies, but also about the owners of different copies.

[0044] The indicator that the agent program automatically monitors Internet resources on which digital music files are posted around the clock; the indicator that the agent program sends information about the detected tag to the owner of the licensed copy of the album and / or the interested party, and / or the owner of the magnetic tape copy immediately with the decoding of the encoded information used to generate the tag; the indicator that the tag generation is launched on the computer of the owner of the licensed copy of the album or the interested party, on which the tag generation program is installed, and / or through the personal account of the cloud service on the Internet, where the tag generation program is installed - these are additional indicators that contribute to the achievement of the intended technical result.

[0045] The feature that the detection of tags is carried out using a developed AI-agent program located on a computer or in a cloud service on the Internet, while the AI-agent program is pre-trained on each generated search tag and a list of checked musical compositions - contributes to the expansion of functional capabilities associated with the detection of an unauthorized digital copy of a musical composition on the Internet.

[0046] Thus, it is the combination of the above-mentioned features that ensures the achievement of the technical result set by the invention, namely, the expansion of the technological and functional capabilities of marking musical compositions on magnetic tape, ensuring the possibility of accessible and wide application of the proposed marking method, since using the proposed method, the owners of a licensed copy of an album can carry out direct copying from a licensed copy of an album (a backup copy of the album master tape) to another magnetic tape, independently replicate albums and issue licenses for the right of direct copying onto magnetic tape to third-party recording companies - since the proposed method, in principle, makes it possible to implement not only the application of a mark, preserving the sound quality of a musical composition, but also ensures the subsequent identification of the mark and the detection of unauthorized digital copies of these musical compositions on the Internet.

[0047] Since the proposed combination of features is not known from the existing level of technology and does not follow from it explicitly - it allows for a higher technical result to be obtained, then the proposed essential features and their combination can be considered to have an inventive step.

[0048] According to the conducted patent information research, no combination of known and new features of the proposed invention was found in the sources of patent and scientific and technical information, which allows us to classify the features as having novelty.

[0049] The description of the implementation of the proposed invention allows it to be classified as industrially feasible.

[0050] Fig. 1 shows an example of a mark made in the form of a continuous analog signal with encoded information visible in a sound editor.

[0051] Fig. 2 shows an enlarged fragment with a mark applied to the sound composition.

[0052] A method for marking a musical composition on magnetic tape and subsequently detecting an unauthorized digital copy of this musical composition on the Internet includes applying at least one mark 1 in the form of an analog signal read together with the musical composition intended for playback.The mark 1 is pre-generated in the frequency range between 13000-50000 Hz - in the form of a continuous analog signal of arbitrary duration and / or in the frequency range from 5 to 50000 Hz - in the form of a sequence of short analog signals of arbitrary duration, by encoding information 2 using a specially developed program installed on the computer of the owner of a licensed copy of the album or an interested person, or placed in the personal account of the cloud service on the Internet provided to him, which ensures the expansion of the technological and functional capabilities of marking musical compositions on magnetic tape, improves the quality of the mark, while maintaining the sound quality of the reproduced musical composition.Next, the generated mark 1 is applied to the main signal 3 anywhere on at least one musical composition on the magnetic tape, preventing overlapping marks. This is accomplished by connecting the sound card of the computer on which the mark generation program is installed and / or via a personal account on the cloud service on the Internet where the mark generation program is installed to the audio system, for example, via a mixing console. The input signal level from the two sources—the sound card and the main signal—is set to be either the same or different, but no more than +9 dB. The ability to apply the mark via the personal account on the cloud service on the Internet allows a wide range of individuals to acquire rights and use the proposed invention for their own needs, and also ensures the legality of the legal relationship between the patent holder for the proposed invention and the copyright holder or author of the audio work released into civil circulation.Subsequent detection of at least one tag on digital copies of musical compositions online is performed using a developed agent program, hosted on a computer or in a personal account on a cloud service. Each generated tag, along with a list of music albums and songs to be scanned, is pre-populated into the agent program. If at least one tag is detected, the agent program identifies it and sends information about the detection of an unauthorized digital copy of the musical composition to the owner of the licensed copy of the album and / or the interested party, and / or the owner of the magnetic tape copy, along with a link to the online resource where the tag was detected on the unauthorized digital copy.Each owner of a licensed copy of an album or interested party pre-creates their own catalog of publications on their computer or in their personal account on the cloud service online. The catalog contains a unique code for each magnetic tape copy customer. This code is used to generate all subsequent tags. When generating a tag, information necessary for subsequent tag identification is encoded, such as: name of the owner of the licensed copy of the album or interested party; album catalog number from the catalog; print run number; number of copies in the print run / print run number; copy recording order number; copy recording date; name of the owner of the magnetic tape copy. Depending on the needs of the owner of the licensed copy of the album or interested party, the encoding information may be supplemented or subtracted as necessary.

[0053] A specific example of the method of applying a mark for marking a musical composition on a magnetic tape

[0054] In this example, a cue was placed on the main signal while the album copy was being recorded. To do this, information allowing for the cue's identification was entered into a specially developed program installed on the record label owner's computer:

[0055] - the name of the owner of the record company that owns the licensed copy of the album;

[0056] - album catalog number from the publication catalog;

[0057] - serial number of the circulation;

[0058] - number of copies in the print run / copy number from the print run;

[0059] - the order number for recording a copy;

[0060] - date of recording the copy;

[0061] - name of the owner of the magnetic tape copy.

[0062] To obtain a copy of an album on magnetic tape, the owner of a record company set up a playback and recording tape recorder. A tape containing a backup copy of the band's album master tape was loaded into the playback tape recorder. A blank tape was inserted into the recording tape recorder to obtain a copy of the band's album. The playback timer was then reset to zero before starting the album copy and after the end of each track (musical composition). This was necessary for the convenience of starting the cue generator, ensuring sequential placement of cue points and avoiding overlapping, since the cue generator is started manually. The playback tape recorder was connected to the first input of an analog mixing console. The computer's sound card, from which the cue points were transmitted as an analog signal, was connected to the second input of the mixing console. The recording tape recorder was connected to the output of the mixing console.After this, the signal level on the input signal level indicator of the mixing console was set to 0 dB using the signal level regulator at the first input.

[0063] Everything is ready to start copying the band's album and applying cue marks. The playback and recording tape recorders were turned on simultaneously. When the playback tape recorder's tape counter reached 20 seconds, cue generation was initiated via the browser. The cue mark was generated as a continuous analog signal in the frequency range between 13,000 and 50,000 Hz and played 5 seconds after the start of cue generation for 10 seconds. Then, after 5 seconds, the cue mark was automatically generated and played in the frequency range from 5 to 50,000 Hz—as a sequence of short analog signals for 10 seconds. After this, cue generation and playback automatically ended.The tags were saved as separate audio files and stored in a catalog—a database in the user's online cloud service account—linked to the band's album catalog number and the order number for the copy. The cycle was repeated when the next track—a musical composition on the album—was played. The tags were saved as separate audio files in the catalog only when the first and second (as a backup copy) songs on the album were recorded.

[0064] To enable the agent program to detect the mark on musical compositions posted online in the event of unauthorized copying of a magnetic tape made from a licensed copy of an album (master tape), a sample generated mark was entered into the agent program. The agent program checks for the mark by reading files containing digitalized analog audio with the .wav extension. However, files in other digital formats, such as .flac, .alac, .aiff, and other extensions, can be used for the agent program's operation. The agent program then automatically monitors internet resources where digital music files are posted around the clock. For this purpose, a digital copy of the musical composition—i.e., an unauthorized copy—was specifically made and posted online.After detecting a tag on a musical composition, the agent program identified it and sent information about the tag to the record label owner, along with a decryption of the encrypted information used to generate the tag. The mere presence of a musical composition with a tag indicates that it is an unauthorized copy, and the agent program "sees" which copy of the magnetic tape it was made from and who owned it, notifying the record label owner with a link to the online resource where the tag was found.

The method of marking according to paragraph 1, characterized in that when generating the mark, the information necessary for its subsequent identification is encoded, for example, such as: - the name of the owner of the licensed copy of the album or the interested party; - album catalogue number from the catalogue of publications; - serial number of the circulation; - number of copies in the print run / copy number from the print run; - order number for recording a copy; - date of recording the copy; - name of the owner of the magnetic tape copy.

3. The marking method according to paragraph 1, characterized in that the interested party is the owner of the recording company and / or the copyright owner, and / or the performer.

4. The marking method according to paragraph 1, characterized in that the agent program automatically monitors Internet resources on which music files in digital formats are posted around the clock.

5. The marking method according to paragraph 1, characterized in that the agent program sends information about the found mark to the owner of the licensed copy of the album and / or the interested party, and / or the owner of the copy of the magnetic tape immediately with the decryption of the encoded information used to generate the mark.

6. The method of marking according to paragraph 1, characterized in that the generation of the mark is started on the computer of the owner of the licensed copy of the album or the interested person - on which the mark generation program is installed and / or through the personal account of the cloud service on the Internet, where the mark generation program is installed.

7. The marking method according to paragraph 1, characterized in that the mark is applied sequentially with or without an interval between the marks.

8. The method of marking according to paragraph 1, characterized in that the detection of marks is carried out using a developed AI-agent program located on a computer or in a cloud service on the Internet, wherein the AI-agent program is pre-trained on each generated sought mark and a list of checked musical compositions.
