Description

    The present invention relates to a karaoke apparatus.

  Various karaoke devices for scoring songs have been developed. For example, in the karaoke apparatus described in Patent Document 1, music data in a MIDI (Musical Instrument Digital Interface: registered trademark) format is reproduced to generate an accompaniment sound and extracted from guide melody data included in the music data. Evaluation is performed based on the result of comparison between elements such as the melody pitch (pitch), sound length, and timing and each element extracted from the voice of the singer, and the singing is scored.

  The guide melody is played along with the accompaniment so that the singer can recognize the melody and sing easily. On the other hand, when evaluating a song, there is also an apparatus that uses reference data, which is performance data of a model song, in addition to a guide melody. Since the guide melody data is often made so that it is not so conspicuous as a performance, reference data may be provided separately from the guide melody when singing volume and inflection are evaluated freely. In the following description, for simplification, all data used for song evaluation is referred to as reference data, and is not distinguished from guide melodies.

By the way, there is also a singing method that brings out a subtle taste by intentionally singing with a slight shift from the original pitch, and many famous singers have this. That is, depending on the tune, there is a case where the taste is deeper when singing with the pitch shifted slightly upward (or lower) than the original correct pitch.
In addition, the scale of folk music generally has a pitch that deviates slightly from the equal temperament. For this reason, when singing folk music with a karaoke device, it is not the same as the pitch indicated by the reference data, but singing with the scale of the original folk music is more like the folk music.
However, with conventional devices, scoring is performed based on the exact pitch of the equal temperament indicated by the reference data, so a good singer who intentionally shifts the pitch to create a taste will follow the pitch. There is a disadvantage that the evaluation is lower than that of a normal level singer.

  The present invention has been made in view of the circumstances described above, and even if singing with a slight shift from the pitch indicated by the reference data, it is recognized as a high evaluation if it is a predetermined shift that enhances the taste of the song. An object of the present invention is to provide a karaoke apparatus that can be used.

(A: 1st Embodiment)
Embodiments of the present invention will be described below with reference to the drawings.
<Configuration of Embodiment>
FIG. 1 is a block diagram showing a configuration of a karaoke apparatus main body 1 according to an embodiment of the present invention, and each part will be described below.
The CPU 11 controls each part of the apparatus by using the RAM 13 as a work area and executing various programs stored in the ROM 12. A communication I / F (interface) 15 receives music data from the host computer 6 that is a music data distribution source, and transfers the music data to an HDD (Hard Disk Drive) 14 under the control of the CPU 11. Data transfer to the HDD 14 by DMA (Direct Memory Access) is also possible.

Here, the structure of music data used in this embodiment will be described.
As shown in FIG. 2, the music data in the present embodiment has a header and a plurality of tracks. Reference data representing the content of a melody (pitch) to be sung by the user is included in the plurality of tracks. There are a reference data track described, a performance track describing performance data representing the contents of karaoke performance sounds, and a lyrics track describing lyrics data representing the contents of lyrics. In the header portion, as shown in FIG. 2, song number data for specifying a song, song title data indicating the song title, genre data indicating the genre, performance time data indicating the performance time of the song, detune information DCH, and the like. include. The detune information DCH indicates the correction amount of the reference data pitch, and is represented by a numerical value in units of cents in the present embodiment. The above music data is described according to the MIDI format.

Next, a specific example of the reference data described in the reference data track will be described.
Since FIG. 3 is a matrix of rows and columns, first the columns will be described.
The delta time in the first column indicates the time interval between events, and is represented by the number of tempo clocks. When the delta time is “0”, it is executed simultaneously with the immediately preceding event. In the second column, the contents of messages of each event of the performance data are described. This message includes a control change message in addition to a note-on message (NoteOn) indicating a sounding event and a note-off message (NoteOff) indicating a mute event. In the example shown in FIG. 3, the control change message is not included.

The third column describes channel numbers. Here, for simplicity of explanation, the channel number of the reference data track is “1”.
In the fourth column, a note number (NoteNum) or a control number (CtrlNum) is described. Which is described depends on the content of the message. For example, in the case of a note-on message or a note-off message, a note number indicating a scale is described here, and in the case of a control change message, a control number indicating the type is described.
The fifth column describes specific values (data) of the MIDI message. For example, in the case of a note-on message or a note-off message, a velocity value representing the sound intensity is described here, and in the case of a control change message, a parameter value corresponding to a control number is described.

Next, each row shown in FIG. 3 is a musical sound parameter indicating the attribute of each note of the melody to be sung, and is composed of a note-on event and a note-off event.
In the example shown in FIG. 3, the length of the delta time 480 is the length of a quarter note. In this case, it is shown that the C4 sound is produced over the length of the quarter note by the event processing of the first and second lines, and the G4 sound is divided by four by the event processing of the third and fourth lines. It is shown that it is pronounced over the length of the note. Then, it is shown that the F4 sound is pronounced over the length of the half note by the processing of the fifth and sixth lines.

When the user performs a music designation operation, the designated music data is read from the HDD 14 based on the music number data and transferred to the MIDI storage area A1 in the RAM 13 (see FIG. 4). The CPU 11 sequentially reads and processes the music data in the MIDI storage area A1, thereby progressing the music performance.
At this time, the reference data is also read out in synchronization with the progress of the music, and the CPU 11 generates reference pitch data RP and reference volume data RV according to the note and velocity of the reference data.

  On the other hand, the voice of the singer inputted to the microphone 4 becomes a singing voice signal S1, which is outputted from the speakers 3 and 3 via the amplifier 21, and also inputted to the voice processing DSP 20. The voice processing DSP 20 performs A / D conversion on the singing voice signal S1, then extracts the pitch and volume of the singing voice, and outputs them as singing pitch data SP and singing volume data SV, respectively. In this case, the extraction processing of the audio processing DSP 20 is performed approximately every 30 ms.

The operation unit 16 is an operation panel provided on the front surface of the karaoke apparatus body 1 and has a number of keys such as a numeric keypad and key control keys. The operation unit 16 has a receiving unit that receives signals (infrared signals, wireless signals, etc.) output from the remote control terminal 5, and the signals received by the receiving unit are transferred to the CPU 11.
The display control unit 17 performs control for displaying video data, lyrics, and the like on the monitor 2. Note that the video data is stored in a video data storage unit (DVD playback device or the like) (not shown), and a video corresponding to the genre of the music is read out. The lyrics are displayed using the lyrics data in the music data, and a color change (so-called wipe) process is performed as the music progresses.
The tone generator 18 generates a musical sound signal corresponding to music data (specifically, performance data in the music data) sequentially read from the CPU 11 as the music progresses, and outputs it to the effect DSP 19.
The effect DSP 19 gives effects such as reverberation and echo to the musical sound signal generated by the sound source device 18. The musical sound signal to which the effect is applied is D / A converted by the effect DSP 19 and then amplified by the amplifier 21 and emitted from the speakers 3 and 3 as a karaoke performance sound. Since the amplifier 21 also amplifies the singing voice signal S1, the singing voice inputted from the microphone 4 and the karaoke performance sound are mixed here.

  Next, the storage area set in the RAM 13 will be described with reference to FIG. 4. The MIDI storage area A1 is an area for storing music data transferred from the HDD 14, and the difference value storage area A2 Various data indicating the difference between the singing and the reference data are sequentially accumulated as the music progresses.

<Operation of Embodiment>
Next, the operation of the karaoke apparatus having the above configuration will be described.
When the user performs a music specifying operation using the numeric keypad of the operation unit 16 or the remote control terminal 5, the music data of the specified music is transferred from the HDD 14 to the MIDI storage area A1 of the RAM 13. The CPU 11 executes the karaoke accompaniment and lyrics display processing by sequentially reading the music data events in the MIDI storage area A1. Specifically, the event data described in the performance track of the musical sound data is output to the sound source device 18 and the lyrics data of the lyrics track is output to the display control unit 17. As a result, the karaoke accompaniment sound is output from the speakers 3 and 3, while the lyrics generated by the display control unit 17 are displayed on the monitor 2.

  On the other hand, the CPU 11 determines reference pitch data RP indicating the pitch to be sung and reference volume data RV indicating the volume to be sung from the note number and velocity of the note-on event (NoteOn) of the reference data read in accordance with the progress of the music. And detune information DCH is read out.

  After generating the reference pitch data DRP and the reference volume data RV as described above, the CPU 11 compares these data with the singing voice. Specifically, the following processes 1 to 3 are performed.

1. The pitch difference data PD is calculated using the reference pitch data RP and the singing pitch data SP, and the pitch difference data PD is corrected according to the value of the detune information DCH. For example, when the detune information DCH is instructed to shift up by one cent, the pitch difference data PD is corrected so as to correspond to the case where the pitch of the reference pitch data RP is one cent higher. Then, the corrected difference value is accumulated and stored in the difference value storage area A2 of the RAM 13 as the pitch difference value data PD. When the detune information DCH is 0, the difference between the reference pitch data RP and the singing pitch data SP is stored without being corrected.
As described above, the difference data is corrected by supplying the MIDI format event data to the sound source device 18, and generally a musical tone signal having an equal temperament pitch is generated. This is because it may be more tasteful to shift slightly, and it is more appropriate to correct the difference data using the detune information DCH for the evaluation of singing in such a song. In the case of the present embodiment, the cent number indicated by the detune information DCH is approximately a fraction of a cent, a few cents, or a few tens of cents.
2. The difference value between the singing volume data SV and the reference volume data GV is accumulated and stored in the difference value storage area A2 as volume difference value data VD.
3. The time difference between the sound generation timing (or mute timing) of the reference data and the rising (or falling) timing of the singing volume data SV is accumulated and stored in the difference value storage area A2 as rhythm difference value data RD.

Next, the CPU 11 reads out the pitch difference value data PD, the volume difference value data VD, and the rhythm difference value data RD accumulated in the difference value storage area A2 of the RAM 13, sums up each, and deducts points according to this summation result. Calculate points. In this case, the deduction point increases as the total value of each difference value data PD, BD, RD increases. Characteristically, the pitch is corrected based on the detune information DCH for the difference between the singing pitch data SP and the reference pitch data RP, and is determined based on the corrected pitch difference data PD. Singing a little off the pitch and singing tastefully will be highly appreciated. Even if singing exactly according to the pitch of the equal temperament, a deduction point is calculated so that the evaluation in this embodiment does not become a high evaluation.
Then, the CPU 11 subtracts this deduction point from the full score (100 points), and outputs the score after the subtraction to the display control unit 17. As a result, the total score is displayed on the monitor 2 under the control of the display control unit 17.

  As described above, the karaoke apparatus according to the present embodiment is higher for a user who sings such a tune that is more enjoyable for singing by shifting from the pitch of the performance sound (for example, equal temperament). It becomes a score and can evaluate the skill of singing correctly.

(B: Other embodiments)
The above is the first embodiment of the present invention. Other embodiments will be described below.

1. When there is detune information DCH, the reference pitch data RP is corrected, and the difference between the corrected reference pitch data (hereinafter referred to as detune reference pitch data DRP) and the singing pitch data SP is detected, and this is used as the pitch difference. Data PD may be used.

2. In the above embodiment, if there is detune information DCH in the header of the music data, the difference data is corrected for all the melodies of the music (or the difference between the detune reference pitch data DRP and the singing pitch data SP). Alternatively, the difference may be corrected only for a predetermined portion of the music (or the difference may be calculated using the detune reference pitch data DRP). This is because, depending on the music, only a specific measure or frame or a specific note may be deepened if it is shifted from the original pitch.
An example of reference data for realizing such scoring will be described. The reference data shown in FIG. 5 is the same as the reference data shown in FIG. 3 except that a control change message is inserted before and after the F4 sound event.
Here, a control change message with a control number “1” is described in the fifth line, and a control change message with a control number “2” is described in the eighth line. In this example, the control number “1” is used for an instruction of “detune start” indicating the start of detune and singing, and the control number “2” is an instruction of “end of detune” indicating the end of the detune. Used for. Therefore, in the example shown in FIG. 5, it is instructed that the F4 sound generated over the length of a half note is a sound to be sung with the pitch shifted. Here, (+15) which is the value of the control number “1” indicates that the song is detuned upward by 15 cents and sung (shifted above the original pitch). When a plurality of notes are located between the control number “1” and the control number “2”, these notes all become notes to be sung by shifting the pitch. As described above, it is possible to instruct in advance for each note the location to be sung by shifting the pitch and the amount of detuning of the reference data.
In the scoring process, the CPU 11 sequentially reads the reference data and monitors whether or not the control number “1” or “2” has been read. , The difference between the reference pitch data RP and the singing pitch data SP is corrected (or the detuned reference pitch data DRP is generated by detuning the reference pitch data RP, and the detuned reference pitch data DRP and the singing pitch data SP are Detect the difference).
In addition, the designation of the note to be sung by shifting the pitch is not limited to the method described above. In short, it is only necessary to specify a note. For example, one or more pitch names whose pitches are to be shifted are indicated in the header portion of the music data, and the CPU 11 recognizes this and performs processing according to the detune information in the note portion. That's fine. This is because some songs are effective when the pitch of a specific pitch name is shifted. For example, there are many such songs in folk music.
The above configuration is schematically expressed as follows.
“Detune information is included in the song data together with detune position designation information that indicates which part of the singing model data is to be corrected.”

3. In the above-described embodiment, when there is detune information DCH, the process of detune information DCH is performed to evaluate the singing, but the evaluation when it is assumed that there is no detune information DCH is also performed in parallel. The final evaluation may be performed using the evaluation result. For example, if both evaluations are compared and the evaluation when detuned is high, a score such as adding a predetermined point to the evaluation score when detuning is not performed (for example, adding bonus points, etc.) You may calculate.

4). You may display on the monitor 2 that it is the note or section which sings with a pitch shifted. This display control may be performed by detecting control change information in the music data, or may be performed for a specific pitch name. In short, the place to be sung by shifting the pitch is specified by reading the reference data, and display control corresponding to it can be performed. Such notification to the user may incorporate a vibration device in the microphone 4 and vibrate the vibration device in a corresponding period to allow the singer to recognize that the pitch is slightly shifted.
Further, depending on the music, it may be selected whether to perform the detuning process before scoring or to perform the scoring without the detune process. This selection may be performed by causing the monitor 2 to display a selection screen under the control of the display control unit 17 and freely selecting it by operating the operation unit 16 or the remote controller 5.

5). In general, music data is often described in the MIDI format. However, in order to make the accompaniment more realistic, it is considered that the music data is reproduced in parallel with the music track recorded in another standard (for example, MP3). Yes. In this case, for example, the frequency of a reference sound (for example, A sound) is 440 Hz, 441 Hz, or 442 Hz, and the orchestra is not constant for each orchestra. Therefore, the MP3 and other tracks that record performances having different frequencies of the reference sound and the musical tone signals generated using the performance data in the MIDI format are not preferable because of a pitch difference. This is because automatic performance using performance data in the MIDI format is generally reproduced by a sound source tuned to 440 Hz.
Thus, when simultaneously playing performance data in a MIDI format with tracks having different tunings, a command called system exclusive is inserted into the performance data in the MIDI format to change the tuning on the playback device side. The change is performed by changing a tuning table provided in the sound source on the playback device side. However, if the tuning table is changed, the musical sound generated from the MIDI sound source will have the same pitch as the performance of other standard tracks such as MP3, but only the sound source has been corrected, and the reference data No modifications can be made to. Therefore, there arises a problem that the pitch of the reference data is deviated from the pitch of the accompaniment that is actually sounded. In this case, a strange state occurs in which the evaluation of a song that is accurately sung in accordance with the accompaniment is lowered. The present invention can also be applied to such a case. That is, the difference between the reference sound of the track according to another standard such as MP3 and the reference sound of the performance according to the MIDI format may be inserted as detune information DCH into the music data. The insertion position in this case may be the header of the music data or the head portion of the reference data.
In addition, since the music is uniquely specified by the music number (identification information), it is known in advance how much the reference data of which music should be detuned. Therefore, for example, as shown in FIG. 6, if a table TB indicating the correspondence between the song number and the detune information DCH is prepared in the HDD 14 or the like, the reference is made by referring to the table TB when the song is designated. Appropriate detuning of data can be performed.

6). In addition, sound information (first reference sound data) indicating a reference sound is recorded at the beginning of a track according to a standard other than MIDI, such as MP3, and the beginning of a reference track in MIDI format (or the beginning of an arbitrary track). A note code (second reference sound data) having a pitch name corresponding to the first reference sound data may be recorded in the portion or the header portion. According to such a configuration, when two reference sound data are reproduced in the karaoke apparatus, if the frequency difference is detected, detune information can be obtained based on the difference. Note that the comparison between the two reference sounds is performed in a state where a reproduction signal is generated, and sound emission from the speaker is muted.
In this case, the second reference sound may not be recorded on the music data side, and the program in the ROM 12 may be set so that the karaoke device sounds before the music is reproduced.

7. In the embodiment described above, the reference data is described according to the MIDI format, and the CPU 11 changes the pitch name (note) indicated by the MIDI format to pitch (frequency) data to generate the reference pitch RP. However, when the reference data is described as pitch information, the reference data read as the music progresses may be output as it is as the reference pitch RP.

8). The function of generating the pitch difference value data PD based on the singing pitch data SR, the reference pitch data RP, and the detune information DCH may be configured as a separate unit as an evaluation system. In other words, the evaluation system and the karaoke system responsible for other functions may be configured as separate units.
FIG. 7 is a block diagram showing a device configuration in this case. In the figure, 30 is an evaluation system and 31 is a karaoke system. The evaluation system 30 receives the singing pitch SR, the reference pitch RP, and the detune information DCH from the CPU 11, generates pitch difference value data PD from these, and supplies them to the CPU 11 (that is, the karaoke system 31 side).
In this case, the CPU 11 does not perform processing based on the detune information DCH, but simply outputs the detune information DCH to the evaluation system 30. Then, the evaluation system 30 calculates the pitch difference value data PD using the reference pitch data RP and the singing pitch data SP instead of correcting the reference pitch data RP using the detune information DCH, and this pitch difference data PD Is corrected according to the detune information DCH and supplied to the CPU 11. The CPU 11 accumulates and stores the supplied pitch difference value data in the difference value storage area A2 of the RAM 13, and thereafter performs the same operation as in the above-described embodiments.
The evaluation system 30 generates detune / reference pitch data DRP from the detune information DCH and the reference pitch data RP, and supplies the CPU 11 with the difference value between the singing pitch data SP and the detune reference pitch data DRP as the pitch difference value data PD. You may make it do.
The configuration as described above has an advantage that the configuration of the karaoke system 31 can be made common regardless of whether or not the detune information DCH is used. In other words, in any case, the CPU 11 may perform scoring based on the pitch difference data PD, so that the program or the like can be implemented without change. If the evaluation system 30 has a function of performing processing based on the detune information DCH, the pitch difference data PD is corrected, and if the evaluation system 30 does not have a processing function for the detune information DCH, the reference pitch. The difference between the data PD and the singing pitch data SP becomes the pitch difference data.
Further, when reading the detune information DCH from the table TB shown in FIG. 6, the CPU 11 may read it and supply it to the evaluation system 30, or the evaluation system 30 may read the detune information DCH directly from the table TB.

9. In each of the embodiments described above, the difference between the singing pitch and the reference pitch is adjusted by using the detune information DCH. However, tracks other than MIDI (tracks for performance data and reference data) and MIDI such as MP3 are used. Even if there is a difference in the tuning of the track according to the standard, if there is no problem, scoring may be performed using the reference data of the MIDI track as it is without using the detune information DCH.
Further, Oite in this case, further use of a detuned information DCH, may be selectively switching configuration processing with and without treatment with a detuning information DCH. An outline of such a configuration is expressed as follows.
