Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a karaoke apparatus which automatically transposes the pitch of a performance song in accordance with the vocal range of the singer.

[0002]

2. Description of the Related Art A karaoke device having a function of reproducing a designated musical piece and mixing and outputting voices inputted from a microphone is not limited to restaurants such as snacks, but also karaoke boxes and buses. It is also popular in mobile units. An ordinary karaoke device has a storage system that stores performance information and image information, an acoustic system that reproduces a performance song and mixes the voice of a singer with it, and a video image that displays a background image and lyrics image according to the performance song. There are many types of musical sound reproduction types that include a system and a control system that controls each of these systems. On the other hand, recently, a musical tone synthesizing type karaoke apparatus has appeared in which necessary music data is taken in from a host station via a communication line. This musical sound synthesizing type karaoke apparatus has a built-in sound source for generating musical sounds based on music data.

The musical tone reproducing type karaoke device cannot respond to requests other than the musical composition stored in the storage system, but if the musical tone synthesizing type karaoke device is used.
Since it is possible to have the song data supplied in response to the singer's request from many song data stored in the host station, in an extreme example, even if there is no song data on the karaoke device side, It will be possible to meet all requests from the singer. The complete tone synthesizing karaoke device has such a configuration, but in order to reduce the communication fee and communication time for accessing the host station each time a request is made, a storage device is provided on the karaoke device side and the karaoke device is loaded from the host station here. There is also a semi-tone synthesis type that stores song data and reuses it.

In any type of karaoke apparatus, there is a case in which a normal singer does not match the original range of a performance song with the singer's range. Therefore, a normal karaoke device performs pitch adjustment (transpose) that raises and lowers the pitch of a performance song, and for many singers with different vocal ranges,
It is generally provided with a function that makes it easy to sing the same performance song. Basically, the amount of transpose can be set manually, but when the singer actually starts singing, there are some that are automatically adjusted according to the characteristics of the vocal range.

[0005]

However, since the conventional automatic transpose function often shifts the pitch of the performance song according to the highest pitch or the lowest pitch of the vocalist's vocal range, the characteristic of the performance song is not always the feature. Often transposes do not fit. In other words, depending on the performance song, even if it is difficult to sing the highest pitch or the lowest pitch,
This is because the singer can enjoy the atmosphere of the song to the maximum extent if the pitch with the highest frequency of occurrence included in the performance song is easy to sing. An object of the present invention is to provide a karaoke device which pays attention to such a point and transposes so that a range of high frequency of appearance included in a musical piece is surely included in a vocal range of a singer.

[0006]

In order to achieve the above object, according to the present invention, a means for reproducing a designated musical piece, a means for designating a musical range included in the musical piece having a high appearance frequency, and the musical piece for playing. And a transposing means for adjusting the median value of the high-frequency range of the performance song to the median value of the vocalist's vocal range.

[0007]

[Operation] When the median value of the high-frequency range included in the performance song is transposed to match the median value of the vocalist's voice range, the singer naturally sings the main part of the desired performance song without overdoing it. be able to. When such a transpose is performed, if the singer's vocal range is narrow, there may be a part that is difficult to sing in the highest pitch or the lowest pitch of the performance song, but the frequency of occurrence is low, so I averaged the whole. In that case, it should be easy to sing. In particular, the frequency range in which the frequency of appearance is high often characterizes the atmosphere of the musical piece being played, so it is expected to be a preferable transpose when enjoying karaoke.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a system configuration diagram for explaining the function of the integrated karaoke system according to the present invention. 61 is a program ROM 23 for the operation of the entire karaoke system
It is a CPU (central processing unit) that controls and manages under B. A random access memory (RAM) 62 is used when the CPU 61 controls and manages the operation of the karaoke system. 63 is a bus (data, address) for connecting the entire system. 6
4 is MIDI (Musical Instrument Digital I
This is an interface for connecting the musical instrument 42. Reference numeral 65 denotes a changer controller for controlling the LD changer 11, which has a replaceable structure so as to be compatible with a plurality of models.

Reference numeral 66 is an ADPCM processor for bit-converting and frequency-converting the ADPCM data output from the sequencer 23B and expanding the ADPCM data. 67 is ADPC
The pitch shifter controls the pitch of the output of the M processor 66 according to the pitch information. Reference numeral 68 is an effector mixer that receives the output of the pitch shifter 67 and the output of the sound source processor 23C. Reference numeral 69 is a microphone effector that adds an acoustic effect such as an echo or an exciter to the output of the microphone 14. 70 is the output of the microphone effector 69 and L
It is an audio DSP (sound field generator) that gives a sound field effect to the audio output of the D changer 11.

The tone generator processor 23C is a so-called music synthesizer which is driven by song data and synthesizes tone signals of a performance song. For example, the tone generator processor 23C includes a tone generator unit that synthesizes tone sounds based on MIDI signals, and a control unit that controls the tone generator unit. ing. The video processor 23D processes character information such as lyrics corresponding to a performance song and background image information such as a still image and a moving image to generate an image signal for display. Here, an example is shown in which the video processor 23D1 for the lyrics image and the video processor 23D2 for the background image are used. The LD changer 11 functions when playing a karaoke piece recorded on an optical disk, or when playing only video information, and when used as a musical tone synthesis system, in synchronization with the accompaniment performance synthesized by the sound source 23C, Video information including a still image of a predetermined frame of a predetermined disc or a moving image having a predetermined frame as a starting point is reproduced. The video selector 23E combines these three types of images into one screen and outputs the combined image.

The operation will be described below. "Music reproduction / music synthesis control" When a music piece is specified by operating the remote controller 24 or the front panel 50, C
The PU 61 refers to the index table stored in the storage means 22C, first confirms whether or not there is data of a song corresponding to the LD in the LD changer 11 as the first rank, and if there is, reproduces that portion. The video signal from the LD is input to the video selector 23E and displayed on the monitor 12, and the audio signal is input to the audio DSP 70 and output from the speaker 15. The singing voice of the singer is converted into an electric signal by the microphone 14 and input to the audio DSP 70 through the microphone effector 69. Since the mixer 13 mixes the performance music and the singing voice, the speaker 15 produces a mixed acoustic output.

When the designated song is not in the LD changer 11, the CPU 61 searches the song held in the HDD device 22C as the second rank. If there is a corresponding song in the HDD device 22C, the song data of the played song is read out and R is read.
Loaded to AM62 and sound source 23C according to this song data
The musical sound is synthesized with and a karaoke performance is performed. The performance of such a sound source karaoke is performed under the control of the sequencer 23B. With respect to the musical piece to be played, musical tone information is successively generated in the tone generator processor 23C in accordance with the musical piece data read from the RAM 62, and is reproduced from the speaker 15 via the mixer effector 68, the audio DSP 70, and the mixer 13.

Regarding the image, similarly, based on the music data read from the RAM 62, the video processor 23D1 and 23D2 generate the lyrics image and the background image according to the progress of the music in accordance with the instruction of the sequencer 23B.
It is displayed on the monitor 12 via the video selector 23C. When the background image from the LD changer 11 is also used, these three images are combined and displayed by the video selector 23E. The lyrics image displayed on the monitor 12 is instructed so that the singer can easily understand where to sing because the color of the displayed lyrics is changed to a character of another color according to the progress of the singing. It Therefore, the singer is monitor 1
Sing with the microphone 14 while watching the lyrics image displayed in 2.

If the corresponding song data is not stored in the HDD device 22C, the CPU 61 controls to fetch the data of the relevant song online from the host station 30 as the third rank. That is, the ISDN line 40 is used to call the host station 30, and when it responds, the music number is sent and the corresponding music data is transferred. Since the music data may be reused, it is stored in the HDD device 22C.

"Transfer Data Format from Host Station" The format of the karaoke song data used in the sound source karaoke device usually starts from a song header and has lyrics with time information and event information, as shown in FIG. Data for one song is constructed by sequentially storing each track such as a display track, a sound source performance track, and a digital audio track. In the format of FIG. 2, the lyrics display track is a set of time series data A1, A2, ... AN, and similarly, the sound source performance track is time series data B1, B.
2, ... BN, and the digital audio track is a set of time series data C1, C2 ,.

"Pitch Control" In the configuration of FIG.
The output of the AD processor 66 is input to the pitch shifter 67, where pitch adjustment (pitch shift) is performed according to the pitch information. Pitch adjustment includes transposition, which changes a part of the pitch in the middle of a song, and transpose, which uniformly shifts the entire song.

As shown in FIG. 3, the pitch information E5 input from the outside corresponds to the pitch shifter 67 and the sound source control E4.
The back chorus data is input to the pitch shifter 67.
Then, the musical tone is pitch-controlled by the sound source control E4. In the case of chorus data with different pitches with the same chorus phrase, such as when a transposition occurs in one song,
Modulation information is sent from the sound source control to the pitch shifter, and the pitch of the chorus data is changed.

With regard to the "automatic transpose" transpose, if the user specifies a range in which he can easily sing,
The karaoke machine automatically determines the optimal transpose value and performs the performance so that the performance is performed. Specifically, the karaoke device records the highest-frequency range for each karaoke song in the header portion of the song data, and when the user specifies the median value or range (upper and lower limits) of his or her vocal range, the karaoke device , The transpose value is set so that the specified median value of the vocal range or the median value of the range matches the median value of the musical range of the karaoke piece, and transposition is automatically performed.

As the median value of the range of karaoke songs, for example, as shown in FIG. 4, a distribution curve of the number of pronunciations for each pitch or the product of the number of pronunciations and the pronunciation length is obtained, and the distribution curve is set to an appropriate threshold value. Use the intermediate value of the local range obtained by slicing with. This median value information is included in the header of the music data. There are various methods of automatic transposition that make it easier to sing a karaoke song, but the method of matching the median range of the song with the median range of the singer's voice as in this example has the highest frequency with the song. Based on the idea that if the part that appears is easy to sing, the whole part will be easy to sing.

When the applied karaoke device is a sound source karaoke device, as shown in FIG.
The median value of the musical tone range is read from (the HDD 22C is sufficient) and used. Reference numeral 101 is a ROM storing a program executed by the CPU 61. In addition, as shown in FIG.
In a karaoke apparatus that uses a digital storage medium such as / CDI, the range data is written in the device 102 such as a CDG / CDI, and the data is read by the song number and used. Further, as shown in FIG. 7, in a karaoke device such as an LD which cannot read digital data, a range data storage device 103 is provided and used. The storage device 103 may be a part of the HDD 22C.
