(Contents of recording control processing program)
Next, the recording control processing program executed by the karaoke apparatus 1 according to the present embodiment will be described in detail with reference to FIG. The recording control processing program is executed by the control unit 10.

  In S <b> 1, the control unit 10 determines whether or not a music reproduction instruction has been given based on an operation signal from the control panel 20. When there is a music reproduction instruction (S1: YES), the control unit 10 shifts the process to S2. When there is no music reproduction instruction (S1: NO), the control unit 10 stands by for processing until there is a music reproduction instruction.

  In S <b> 2, the control unit 10 starts playback of the specified karaoke song based on the song playback instruction and starts recording by the recording device 55. Accompanied audio signal B related to the karaoke music piece is input from the music piece reproduction unit 43 to the voice comparison unit 44 and the mixing amplifier 45 as needed. Further, when there is an audio input (karaoke singing or performance) to the first connection terminal 41 and the second connection terminal 42, the input audio signals (the first input audio signal Aa and the second input audio signal Ab) are input. Are input to the audio comparison unit 44 and the mixing amplifier 45. The mixing amplifier 45 outputs a mixed audio signal based on the input audio signals (accompaniment audio signal B, first input audio signal Aa, second input audio signal Ab). Therefore, the karaoke apparatus 1 can start audio output from the speaker 50 and recording by the recording apparatus 55 based on the mixed audio signal from the mixing amplifier 45.

  After shifting to S <b> 3, the control unit 10 causes the audio comparison unit 44 to perform input audio signal comparison processing. In the input audio signal comparison process (S3), the control unit 10 uses the audio comparison unit 44 to determine whether or not the accompaniment audio signal B is included in the second input audio signal Ab. The signal Ab and the accompaniment sound signal B are compared.

  Specifically, first, the control unit 10 controls the audio comparison unit 44 to perform filtering on a predetermined frequency band of the second input audio signal Ab. Here, the frequency band that the singing voice can take has characteristics different from the frequency band that the musical instrument performance can take. Therefore, when filtering is applied to a frequency band (for example, 87 Hz to 880 Hz) related to the singing voice, the voice related to the karaoke singing and the voice related to the accompaniment music collected by the additional microphone Ma are added to the second input audio signal Ab. Is included, the sound signal related to the musical instrument performance (that is, the accompaniment sound signal B) is extracted from the second input sound signal Ab. Thereafter, the control unit 10 compares the audio signal related to the musical instrument performance extracted from the second input audio signal Ab with the accompaniment audio signal B input from the music playback unit 43, and determines whether or not they match. To do. After storing the comparison result in the RAM of the control unit 10, the control unit 10 ends the input audio signal comparison process (S3), and proceeds to S4.

  In S4, the control unit 10 determines whether or not the second input audio signal Ab includes the accompaniment audio signal B based on the processing result of the input audio signal comparison process (S3). When the second input audio signal Ab includes the accompaniment audio signal B (S4: YES), the control unit 10 shifts the process to S5. On the other hand, when the second input audio signal Ab does not include the accompaniment audio signal B (S4: NO), the control unit 10 shifts the process to S6.

  In S5, the control unit 10 determines whether or not the reproduction of the karaoke music has been completed. When the reproduction of the karaoke music has been completed (S5: YES), the control unit 10 shifts the process to S8. On the other hand, when the reproduction of the karaoke music is still continued (S5: NO), the control unit 10 returns the process to S3.

  After shifting to S <b> 6, the control unit 10 causes the voice comparison unit 44 to execute reference data comparison processing. In the reference data comparison process (S6), the control unit 10 determines whether or not the audio signal related to the singing voice included in the second input audio signal Ab conforms to the evaluation reference data related to the karaoke song. Therefore, the voice comparison unit 44 compares the second input voice signal Ab with the evaluation reference data.

  Specifically, first, the control unit 10 controls the voice comparison unit 44 to filter the frequency band (for example, 87 Hz to 880 Hz) related to the singing voice of the second input voice signal Ab. Thus, if the second input audio signal Ab includes a voice related to the karaoke song, the voice signal related to the karaoke song is extracted from the second input voice signal Ab. Then, the control unit 10 acquires evaluation reference data relating to the karaoke piece being played from the karaoke data storage unit 15 and inputs the evaluation reference data to the voice comparison unit 44. The voice comparison unit 44 relates to the extracted karaoke song by comparing the singing voice related to the karaoke song extracted from the second input voice signal Ab with the evaluation criteria such as the pitch defined in the evaluation reference data. It is determined whether or not the singing voice conforms to the evaluation reference data. Note that “according to the evaluation standard data” means that when the singing voice extracted from the second input audio signal Ab is scored by the singing scoring function in the karaoke apparatus 1 using the evaluation standard data, a predetermined standard is used. It means a state where the number of points (for example, 60 points out of 100) is greater. After storing the comparison result in the RAM of the control unit 10, the control unit 10 ends the reference data comparison process (S6), and proceeds to S7.

  In S7, the control unit 10 determines whether or not the second input audio signal Ab conforms to the reference pitch based on the processing result of the reference data comparison process (S6). When the second input audio signal Ab conforms to the reference pitch (S7: YES), the control unit 10 shifts the process to S5. On the other hand, when the second input audio signal Ab does not conform to the reference pitch (S7: NO), the control unit 10 shifts the process to S10.

  In S <b> 8, the control unit 10 determines that the karaoke song has been performed in a state where the additional microphone Ma is connected to the second connection terminal 42. Exit. After the recording by the recording device 55 is finished, the control unit 10 shifts the process to S9.

  In S9, since the karaoke song is performed in a state where the additional microphone Ma is connected to the second connection terminal 42, the control unit 10 executes the recorded content posting process. In the recorded content posting process (S9), the control unit 10 reads the recorded data generated by the recording device 55 and uploads it as posted data to the posted database 71 of the server 70 via the communication I / F 60. At the time of uploading, the control unit 10 receives input of information (for example, a user ID or the like) related to the singer or the karaoke piece by the control panel 20. When the recorded content posting process (S9) ends, the control unit 10 ends the recording control process program.

  When the process proceeds to S10, the control unit 10 does not include the accompaniment audio signal B in the second input audio signal Ab, and the second input audio signal Ab does not conform to the reference pitch. It is determined that the electric instrument E is not connected to the second connection terminal 42 and the recording by the recording device 55 is terminated. Recording by the recording device 55 is terminated. After the recording by the recording device 55 is finished, the control unit 10 shifts the process to S11.

  In S <b> 11, the control unit 10 does not correspond to the a cappella singing part and can determine that the electric musical instrument E is connected to the second connection terminal 42, and therefore performs the posting prohibition process. In the posting prohibition process (S11), the control unit 10 deletes the recorded data recorded up to the present time from the recorded data storage unit of the recording device 55. As a result, the output of the recording data is prohibited, and the uploading of the recording data to the server 70 and the disclosure / browsing are also prohibited. After finishing the posting prohibition process (S11), the control unit 10 ends the recording control process program.

  As described above, the karaoke system according to this embodiment includes the karaoke apparatus 1 and the server 70. The karaoke device 1 includes a karaoke data storage unit 15, a speaker 50, a microphone M, and a recording device 55, and can perform karaoke singing regarding desired karaoke music and generate recording data related to the karaoke singing. . The server 70 has a posting database 71, stores the recording data uploaded from the karaoke apparatus 1 in the posting database 71 as posting data, and manages it so that it can be accessed externally.

  Here, the karaoke apparatus 1 has a second connection terminal 42 configured to be connectable to the output terminal of the additional microphone Ma and the output terminal of the electric musical instrument E. And when the said karaoke apparatus 1 judges that the 2nd input audio | voice signal Ab input from the 2nd connection terminal 42 contains the accompaniment audio | voice signal B which concerns on an accompaniment sound (S4: YES), the said 2nd connection terminal 42, it is determined that the additional microphone Ma is connected, and when recording by the recording device 55 is completed, the recording data is uploaded to the server 70 as post data (S9). On the other hand, when it is determined that the second input audio signal Ab does not include the accompaniment audio signal B (S4: NO), the karaoke apparatus 1 deletes the recorded data and uploads it to the server 70 as post data. It is prohibited (S11).

  When the electric musical instrument E is connected to the second connection terminal 42, the accompaniment sound output from the speaker 50 is not collected. That is, when the electric musical instrument E is connected to the second connection terminal 42, the karaoke apparatus 1 does not reliably upload the recorded data as post data to the server 70. As a result, since the recording data including the performance sound of the electric musical instrument E is output to the server 70 and is not widely disclosed to the public, the karaoke system can reduce the management burden on the server administrator.

  In addition, when it is determined that the second input audio signal Ab does not include the accompaniment audio signal B (S4: NO), the karaoke apparatus 1 according to the present embodiment performs the second input by the reference data comparison process (S6). The audio signal Ab is compared with the evaluation reference data of the karaoke piece. Here, some karaoke songs have a part that sings with a cappella (unaccompanied). In this case, the second input audio signal Ab does not include the accompaniment audio signal B even if the additional microphone Ma is connected to the second connection terminal 42 and the karaoke song of the a cappella portion is performed.

  In this regard, when the second input audio signal Ab conforms to the evaluation reference data (S7: YES), the karaoke device 1 uploads the recording data recorded by the recording device 55 to the server 70 as post data. Is allowed (S9). That is, the karaoke apparatus 1 can appropriately upload the recorded data to the server 70 as post data even when the karaoke piece having the a cappella portion is used. The karaoke apparatus 1 deletes the recorded data recorded by the recording apparatus 55 and prohibits uploading to the server 70 as post data when the second input audio signal Ab does not conform to the evaluation reference data. (S11). As a result, even when a karaoke piece having an a cappella portion is used, the recorded data including the performance sound of the electric musical instrument E is not uploaded to the server 70 and is not publicly used. The management burden on the server administrator can be reduced.

  Although the present invention has been described based on the embodiments, the present invention is not limited to the above-described embodiments, and various improvements and modifications can be made without departing from the spirit of the present invention. For example, in the present embodiment, the recording device 55 handles the recording data in which only the sound is recorded as post data. However, the present invention is not limited to this mode. The following embodiments can be adopted. For example, a digital video camera can be added to the above-described embodiment, and data obtained by combining captured moving image data and recording data can be used as post data.

  In the present embodiment, in the recording control processing program, the input audio signal comparison process (S3) and the reference data comparison process are performed for the second input audio signal Ab input from the second connection terminal 42 to the audio comparison unit 44. Although the process of (S6) etc. was performed, it is not limited to this aspect. For example, the first input audio signal Aa input from the first connection terminal 41 to the audio comparison unit 44 is also subjected to processing such as input audio signal comparison processing (S3) and reference data comparison processing (S6). There may be. With this configuration, even when the microphone M connected to the first connection terminal 41 is removed and the electric musical instrument E is connected to the first connection terminal 41, the management burden of the server administrator is appropriately Can be reduced.

  Further, the above-described flowchart is merely an example, and the processing may be realized by another flowchart as long as a result equivalent to each processing of the flowchart can be obtained.

  The present invention can also be realized as a karaoke apparatus, a karaoke system, a program for causing a computer to execute the method, a recording medium on which the program is recorded, and the like.
