Be controlled. For example, when the pan pot is 0, only the left speaker 44l is output, when 64, the output balance from the left and right speakers 44 is equal, and when 127, only the right speaker 44r is output. . That is, the smaller the pan pot is, the larger the proportion of the sound allocated to the left speaker 44l is, and the larger the proportion is, the larger the proportion of the sound allocated to the right speaker 44r is. This panpot is normally determined in advance in music data (performance information) corresponding to each performance song. In the conventional control, the panpot was not changed during karaoke performance. The sound field setting means 98 of the example sets the sound field by changing the pan pot via the stereo relation value setting means 100 when the performance control means 94 outputs the performance.

  Further, the frequency characteristic is a sound pressure gain for each frequency band when a plurality of frequency bands are defined, for example, in other words, for each frequency band when the frequency is changed with a constant input level. This corresponds to the output level. By setting this frequency characteristic, it is possible to increase the sound pressure in a predetermined frequency band in the performance tune outputted by the synthesizer 38, or conversely decrease the sound pressure in the predetermined frequency band. The sound field setting means 98 preferably sets the frequency characteristics related to the output of the musical composition by controlling the setting of the equalizer provided in the amplifier mixer 42 and the like via the frequency characteristic setting means 102. Note that the equalizer to be controlled by the frequency characteristic setting means 102 may be provided between the synthesizer 38 and the amplifier mixer 42 as a separate device from the amplifier mixer 42, for example.

  FIG. 5 is a schematic diagram showing an example of the arrangement of the pair of speakers 44r and 44l in the private room 14 in which the karaoke apparatus 16 is installed. As shown in FIG. 5, the pair of speakers 44r and 44l provided in the karaoke device 16 are, for example, left and right in the private room 14 with respect to the karaoke device 16 (the video display device 30 and the commander main body). It is installed near the corner. That is, for example, as shown in FIG. 5, the speaker 44 r is arranged at one corner of the private room 14 on the right side toward the karaoke device 16, and the speaker 44 l is arranged at one corner of the private room 14 on the left side toward the karaoke device 16. The In such a configuration, when karaoke performance is performed by the karaoke apparatus 16, a performance tune (performance output from the speaker 44) is set according to the setting of the panpot or the like which is a stereo-related value and the setting of the frequency characteristic even at the same place. Sound) is heard differently.

  6 to 9 are balance correlation diagrams of microphone input sound determined according to the sound field setting in the karaoke performance by the karaoke device 16 and performance sound of each instrument in MIDI, and panning ( The two-dimensional coordinates are shown with the horizontal axis of sound panpot (sound image) and the vertical axis of frequency characteristics. 6 to 9, the relationship between the panning corresponding to the sound information (microphone sound) input from the microphone 40 and the strength of the frequency component included in the sound information (hereinafter, frequency band) is shown. A range to be shown is indicated by a broken line, and a range corresponding to a guide melody in MIDI data (corresponding to a vocal part in a performance music, for example, a melody by vibraphone or the like) is indicated by a one-dot chain line. Further, the ranges corresponding to the performance sound, microphone sound, and guide melody of each musical instrument (string system such as violin, drum sound, bass sound, guitar system, etc.) in FIGS. 6 to 9 are plural in the target MIDI. This corresponds to panning and frequency characteristics determined for each track. In these figures, when the pair of speakers 44 are considered to correspond to each other on the horizontal axis, the horizontal axis indicates the positional relationship between the left and right (panning) related to the three-dimensional sound of the performance sound output from the speakers 44. A position where each performance sound is sounded in the three-dimensional sound corresponds to the range of each performance sound shown in FIGS. The vertical axis indicates in which frequency band the performance sound is strengthened in the frequency characteristics, and the frequency band in which each performance sound is strengthened corresponds to the range of each performance sound shown in FIGS. That is, the frequency characteristic indicated by the vertical axis in FIGS. 6 to 9 corresponds to the frequency band in which each performance sound is strengthened.

  Among the balance correlation diagrams shown in FIGS. 6 to 9, FIG. 6 illustrates the relationship corresponding to the default sound field setting determined in advance for the performance music (MIDI data) to be processed. In the setting shown in FIG. 6, the sound field setting faithful to the original music is set, and the range corresponding to the input voice information of the microphone 40 surrounded by a broken line is the range corresponding to the guide melody, the guitar system, or the like. It can be seen that it partially overlaps the range corresponding to the performance sound. In such a setting, it is possible to enjoy a full-fledged performance by being faithful to the original music, but on the other hand, the voice information input from the microphone 40 tends to be buried in other performance sounds such as a guide melody, The performer (singer) is characterized by difficulty in hearing his / her voice. On the other hand, FIG. 9 illustrates a sound field setting in which ranges corresponding to guitar-type performance sounds, guide melodies, strings-type performance sounds, and the like are separated from ranges corresponding to the input audio information of the microphone 40. doing. In the setting shown in FIG. 9, since the voice information input from the microphone 40 is not buried in other performance sounds, it is easy for the performer to hear his / her voice, but the performance is performed to deviate from the setting faithful to the original music. There is a feature that the sense of reality is sacrificed to some extent. Hereinafter, based on such characteristics, the sound field setting control by the sound field setting means 98 of the present embodiment will be described in detail.

  The sound field setting means 98, based on the evaluation result by the performance evaluation means 96, generates a sound field related to the output of the performance tune by the karaoke device 16 during a karaoke performance whose user is the performance result. Set. Preferably, as shown in FIGS. 6 to 9, when two-dimensional coordinates having a stereo relation value (pan pot) and a frequency characteristic as one axis are considered, the lower the evaluation result by the performance evaluation means 96 is, The sound field is set so that the range corresponding to the element of the performance music is separated from the range corresponding to the audio information input from the microphone 40. Here, the element of the performance music is, for example, a performance sound of at least one type of musical instrument among a plurality of types of musical instruments related to the target performance music. That is, the sound field setting means 98 has at least one of the plurality of kinds of musical instruments from the range corresponding to the sound information input from the microphone 40 at the coordinates as the evaluation result by the performance evaluation means 96 is lower. The sound field is set so that the range corresponding to the performance sound of the instrument is separated. As the performance sound to be separated, a guide melody, a string performance sound, a guitar performance sound, and the like can be considered. In other words, the sound field setting means 98 sets the sound field so that the lower the evaluation result by the performance evaluation means 96 is, the closer the phoneme related to the performance music arranged near the center in the coordinates is to the side. .

  For example, the sound field setting means 98 is based on the evaluation result by the performance evaluation means 96, and the sound related to the output of the performance tune by the karaoke device 16 at the time of karaoke performance mainly with the user according to the evaluation result. Control is performed to set the field to any one of the settings shown in FIGS. For example, in the aspect in which the performance evaluation means 96 numerically evaluates the performance such as how many points out of 100, the sound field setting means 98 is shown in FIG. 6 when the evaluation result is 90 points or more. When the sound field setting is 80 to 89 points, the sound field setting shown in FIG. 7 is shown. When the sound field setting is 70 to 79 points, the sound field setting shown in FIG. 8 is shown in FIG. Apply each sound field setting. That is, the lower the evaluation result by the performance evaluation means 96, the more the guide sound, the string performance sound, and the guitar performance sound correspond to the sound information input from the microphone 40 at the coordinates. Set the sound field to separate the range. In other words, the lower the evaluation result by the performance evaluation means 96 is, from the range corresponding to the voice information input from the microphone 40 at the coordinates, the guide melody, the string-type performance sound, and the guitar-type performance sound. Set the sound field moved in the direction to separate the corresponding range. Here, the direction in which the range corresponding to each performance sound is separated from the range corresponding to the sound information is a direction in which the overlap of the range of each performance sound becomes smaller than the range corresponding to the sound information. Specifically, this is the direction in which the overlap of the frequency characteristics (frequency band) with the audio information is reduced, or the panning position difference is increased.

  In the sound field setting shown in FIG. 7, compared to the sound field setting shown in FIG. 6, the center of the guide melody and the string-type performance sound is moved 15% by moving the frequency characteristic to the high frequency side. In addition, the center of the guitar-related performance is left 15% by panning left and right. Furthermore, it is preferable that the volume is increased by 10% for the drum sound and the bass sound. Such a change in the sound field setting makes it easier to hear your own singing sound compared to the sound field setting shown in FIG. 6, and by increasing the volume of the rhythmic instrument, it is easier to pick up the rhythm and provide a sense of stability. Can be improved.

  Further, in the sound field setting shown in FIG. 8, compared to the sound field setting shown in FIG. 6, a 25% center is made free by moving the frequency characteristics to the high frequency side for the guide melody and the string-type performance sound. In addition, 25% of the center is left by panning left and right for guitar-related performance sounds. Furthermore, it is preferable that the volume is increased by 15% with respect to the drum sound and the bass sound. Such a change in the sound field setting makes it easier to hear your own singing sound compared to the sound field setting shown in FIG. 7, and the rhythmic instrument volume is increased to make the rhythm easier to take and stable. A feeling can be improved.

  Further, in the sound field setting shown in FIG. 9, compared to the sound field setting shown in FIG. 6, the center of the guide melody and the string-type performance sound is moved 30% by moving the frequency characteristics to the high frequency side. In addition, the center of the guitar-related performance sound is 30% free by panning left and right. Further, it is preferable that the volume is increased by 20% for the drum sound and the bass sound, and the volume is increased by 10% for the guide melody. Such a change in the sound field setting makes it easier to hear your own singing sound compared to the sound field setting shown in FIG. 8, and the volume of the rhythmic instrument is increased to make the rhythm easier to take and stable. A feeling can be improved. Further, by increasing the volume of the guide melody, it is possible to prevent the guide melody from becoming difficult to hear due to increasing the volume of the rhythmic instrument.

  The sound field setting means 98 preferably sets the sound field related to the output of the performance music as described above based on the evaluation result by the performance evaluation means 96 when the performance music related to the evaluation result is played. . That is, for each performance piece, the sound field is set based on the evaluation result by the performance evaluation means 96 related to the performance piece. Specifically, when the performance music reserved in the reserved music table 68 is started to be output, the performance evaluation results stored in the SNS database 86 corresponding to the user who is the music selection subject of the performance music are output. A performance evaluation result corresponding to the performance music related to the start is read, and a sound field is set based on the evaluation result. By such control, it is possible to set an optimal sound field for each performance piece individually, and it is possible to realize a sound field setting that is easy to sing according to the singing level of each performance piece for each user.

  Further, the sound field setting means 98 preferably relates to the output of the target performance song based on the evaluation result by the performance evaluation means 96 relating to the performance music having the same genre as the target performance music. Set the sound field as described above. That is, for each performance song, the sound field is set based on the evaluation result by the performance evaluation means 96 relating to the performance song having the same genre as the performance song. Specifically, when the performance music reserved in the reserved music table 68 is started to be output, the performance evaluation results stored in the SNS database 86 corresponding to the user who is the music selection subject of the performance music are output. A performance evaluation result corresponding to a performance music having the same genre as the performance music related to the start is read, and a sound field is set based on, for example, an average value of the evaluation results. By such control, it is possible to set an optimal sound field for each performance song belonging to each genre, and to realize the sound field setting that is easy to sing according to the singing level of each genre for each user. it can.

  First, in step (hereinafter, step is omitted) SA1, it is determined whether or not login information, that is, identification information (user ID) and a login password have been input via the electronic sample device 22 or the like. If the determination at SA1 is negative, the processing below SA7 is executed. If the determination at SA1 is affirmative, at SA2, the identification information and login password entered at SA1 are stored in the server. Transmitted to the device 20. Next, in SA3, it is determined whether or not a response indicating that the server apparatus 20 has successfully logged in is returned. If the determination at SA3 is affirmative, login processing is normally performed at SA4, and information such as the user's name (nickname) is transferred from the SNS database 86 of the server device 20 to the communication line 18 at SA5. After being downloaded and stored in the karaoke device 16 so that it can be displayed on the electronic quick sample device 22 or the like, the processing below SA7 is executed, but if the determination of SA3 is negative, in SA6, After the fact that an error has occurred is displayed on the electronic quick sample device 22 or the like, it is determined in SA7 whether or not there has been an input for performing a logout process of a predetermined user by the electronic quick sample device 22 or the like. If the determination at SA7 is negative, the routine is terminated. If the determination at SA7 is affirmative, after the logout process of the target user is performed at SA8, This routine is terminated.

  FIG. 11 is a flowchart for explaining a main part of the sound field setting control by the CPU 50 of the karaoke apparatus 16 and is repeatedly executed at a predetermined cycle.

  First, in S1, it is determined whether or not the sound field automatic setting mode is set. If the determination in S1 is negative, the routine is terminated accordingly. If the determination in S1 is affirmative, in S2, a predetermined performance is performed by an input operation using the electronic quick sample apparatus 22 or the like. It is determined whether or not a song selection input operation for selecting a song as a reserved song has been performed. If the determination in S2 is negative, the processing from S4 onward is executed. If the determination in S2 is affirmative, in S3, the musical composition that has been selected and input by the electronic quick sample device 22 or the like. Are stored in the reserved music table 68 as reserved music in association with the user ID of the user who is the main music selection. Next, in S4, whether the karaoke performance of the predetermined performance music is started by the karaoke device 16 at the timing of starting the performance of the highest-order reserved music stored as the reserved music in the reserved music table 68 or not. It is determined whether or not. When the determination at S4 is negative, the processing after S2 is executed again. However, when the determination at S4 is positive, the processing after S5 is executed.

  In S5, the server device 20 is inquired, and the information stored in the SNS database 86 corresponding to the user who is the subject of the performance corresponds to the musical piece played by the karaoke device 16. It is determined whether or not a performance evaluation result or a performance evaluation result corresponding to a performance music having the same genre as the performance music is stored. If the determination in S5 is negative, the processing from S8 is executed, but if the determination in S5 is affirmative, in S6, the SNS database 86 corresponding to the user who is the subject of the performance. The performance evaluation result corresponding to the performance music played by the karaoke apparatus 16 or the performance evaluation result corresponding to the performance music having the same genre as the performance music is stored (downloaded). Next, in S7, based on the performance evaluation result read in S6, the sound field setting related to the output of the performance music by the karaoke apparatus 16 is performed. For example, in the coordinates with the panpot and frequency characteristics as one axis, the lower the evaluation result read out in S6, the more the range of the musical composition input from the range corresponding to the audio information input from the microphone 40. The sound field is set so as to separate the corresponding ranges.

  Next, in S8, performance evaluation is performed using the pitch, output timing, and the like as evaluation criteria corresponding to the sound input from the microphone 40 in parallel with the output of the performance tune by the synthesizer 38. Next, in S9, it is determined whether or not the karaoke performance is to be terminated, for example, when the performance tune that has been performed by the karaoke apparatus 16 has been played to the end. If the determination in S9 is negative, the processing from S8 is executed. If the determination in S9 is affirmative, in S10, the performance evaluation result for the entire song is based on the evaluation result in S8. And the evaluation result is displayed on the video display device 30. Next, in S11, the performance evaluation result calculated in S10 is transmitted (uploaded) to the server device 20 in association with the user ID of the user who is the performance subject and the music selection number of the target performance music. After being stored in the SNS database 86 as information relating to the user, this routine is terminated.

  In the above control, SA1 to SA6 are operations of the login authentication control means 90, S2 and S3 are operations of the music selection input control means 92, S4 and S9 are operations of the performance control means 94, and S8 and S10 are operations of the performance control means 94. S7 corresponds to the operation of the performance evaluation means 96 and the operation of the sound field setting means 98, respectively.

  As described above, according to this embodiment, on the basis of the audio information input from the microphone 40 which is an audio input device in parallel with the output of the performance music, the performance music Based on the evaluation results by the performance evaluation means 96 (S8 and S10) for performing the performance evaluation and the performance evaluation means 96, the performance of the performance music by the karaoke apparatus 16 is performed during the performance mainly by the user according to the evaluation result. Since the sound field setting means 98 (S7) for setting the sound field related to the output is provided, an optimal sound field can be set according to the singing level for each user. That is, the karaoke apparatus 16 which implement | achieves the sound field setting which is easy to sing according to the singing level for every user can be provided.

  Further, the sound field setting means 98 relates to a stereo-related value that determines an allocation for each speaker 44 with respect to the stereo output of the performance song by the plurality of speakers 44 provided in the karaoke apparatus 16 and the output of the performance song. Since the frequency characteristic is set based on the evaluation result by the performance evaluation means 96, an optimal sound field can be set in a practical manner in accordance with the singing level for each user.

  Further, the sound field setting means 98 corresponds to the sound information input from the microphone 40 as the evaluation result by the performance evaluation means 96 is lower in the coordinates having the stereo relation value and the frequency characteristic as one axis. Since the sound field is set so that the range corresponding to the element of the performance music is separated from the range, the higher the singing level, the more faithful the sound field of the original music, while the lower the singing level By setting the sound field to be easy to hear one's singing voice input from the microphone 40, an optimal sound field can be set in a practical manner according to the singing level for each user.

  The performance control means 94 is for outputting performance sounds of a plurality of types of musical instruments defined in the musical score information corresponding to the performance music, and the sound field setting means 98 is evaluated by the performance evaluation means 96. The lower the result is, the more the sound field is separated from the range corresponding to the sound information input from the microphone 40 at the coordinates, the range corresponding to the performance sound of at least one of the plurality of musical instruments. As the singing level is higher, the sound field is more faithful to the original song. On the other hand, when the singing level is lower, the sound field is easier to hear. Thus, an optimal sound field can be set in a practical manner according to the singing level for each user.

  The performance evaluation means 96 performs performance evaluation of the performance tune for each performance tune outputted by the karaoke device 16, and the sound field setting means 98 is responsive to the evaluation result by the performance evaluation means 96. Based on this, the sound field related to the output of the performance song is set when the performance song related to the evaluation result is played. The sound field can be set to be easy to sing.

  In addition, the performance tune is stored in association with at least one genre as attribute information in advance, and the performance evaluation means 96 stores the performance tune for each performance tune output by the karaoke device 16. The sound field setting means 98 outputs the performance music to be processed based on the evaluation result by the performance evaluation means 96 related to the performance music having the same genre as the performance music to be performed. Therefore, according to the singing level for each genre to which the target performance music belongs, the sound field related to the output of the performance music can be set to be easy to sing.

However, the present invention is not limited to this. For example, a part or all of the control functions may be provided as individual control devices. A part of the control function may be provided in an input device such as the electronic sample device 22 or the server device 20. For example, in the aspect in which login authentication for the karaoke system 10 is substantially performed on the server device 20 side, the karaoke device 16 only needs to input or transmit a user ID and a login password. It may be performed on the server device 20 side.

  In the above-described embodiment, the sound field setting means 98 is input from the microphone 40 as the evaluation result by the performance evaluation means 96 is lower at coordinates having the stereo relation value and the frequency characteristic as one axis. The sound field is set so that the range corresponding to the element of the musical performance is separated from the range corresponding to the audio information, but the present invention does not necessarily control both the stereo-related value and the frequency characteristic. The lower the evaluation result by the performance evaluation means 96, the lower the evaluation result by the performance evaluation means 96, the control of moving the panpot of a predetermined musical instrument left and right among the plural types of musical instruments related to the target musical composition, and the frequency characteristics of the guide melody The control for shifting to the side or the like may be performed independently, and such a control also exhibits the advantageous effect of the present invention.
