Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a karaoke apparatus and a karaoke reproducing method for adding an auxiliary singing signal such as a model singing signal to an accompaniment signal in accordance with a sound input from a microphone (hereinafter abbreviated as a microphone) or the like. .

[0002]

2. Description of the Related Art In recent years, an audio signal composed of accompaniment has been reproduced in an audiovisual apparatus while displaying lyrics on a screen and simultaneously displaying a background image, and the microphone audio input signal of a user has been adjusted accordingly. 2. Description of the Related Art A device for synthesizing a microphone sound is widely used as a karaoke device for home use or business use. Therefore, if you have a function to play the model singing signal recorded as a model when you do not know the timing or melody to start singing while singing, the user can know how to sing. It is convenient. Therefore, there is a karaoke apparatus having a function of switching to a model singing signal when the microphone sound from the user disappears.

Generally, a karaoke-only disc such as a laser disc has two channels, a digital audio channel and an analog audio channel. An accompaniment signal is recorded in a digital audio channel in a stereo system. On the other hand, the analog audio channel is recorded in a so-called audio multiplexing method including a model singing signal (hereinafter referred to as an audio multiplexing method). In the audio multiplex system, only an accompaniment signal of music is recorded in an L channel signal of an analog audio channel, and a model singing signal is added to an accompaniment signal and recorded in an R channel signal. Accompaniment signals of both the L channel and the R channel of the analog audio channel are recorded in monaural and in phase. In addition, a code for identifying a recording format of the audio multiplex system is often recorded on a karaoke exclusive disk such as a laser disk.

A conventional karaoke apparatus having a function of switching a model singing signal using a laser disk or the like will be described below. FIG. 6 is a block diagram showing the configuration of a conventional karaoke apparatus. 111 is a disk or the like (not shown)
Audio input terminal for reading and inputting recording signals from
01 is an accompaniment reproducing means for reproducing an accompaniment signal, 102 is an exemplary singing reproducing means for reproducing an exemplary singing signal, 112 is a microphone input terminal, 103 is a microphone volume detecting means for detecting the presence or absence of a microphone voice input from a user, 104
Is based on the detection result of the microphone volume detecting means 103.
An addition means 113 for determining whether or not to add the model singing signal to the accompaniment signal is an output terminal. An output signal from the addition means 104 is output to an amplifier device (not shown) connected to this terminal. .

In FIG. 6, an accompaniment reproducing means 101 selects the above-mentioned digital audio channel from the recording signals of a disk or the like input to the audio input terminal 1 and reproduces the accompaniment signal. The model singing reproduction means 102 similarly selects an analog audio channel and subtracts the L channel reproduction signal from the R channel reproduction signal. This is because the accompaniment signal and the model singing signal are recorded in the R channel, and only the accompaniment signal is recorded in the L channel. By subtracting the reproduction signal, only the model singing signal can be extracted. Further, the microphone volume detection means 103 detects presence / absence of microphone sound input from the microphone sound from the user. The microphone volume detection means 103 uses a band-pass filter to pass a signal of only the voice band to the microphone voice input, and sets a flag as to whether or not there is an amplitude level equal to or higher than a specified value within a predetermined period. And the like. The adding means 104 is configured to add only the accompaniment signal when the microphone sound is present and to output the model singing signal to the accompaniment signal when the microphone sound disappears, based on the detection result of the microphone volume detecting means 103. When the microphone is lost due to the song being uncertain due to the user's singing, the user can remember the song or practice by reproducing the model singing signal. When the user starts singing again and the microphone voice is input, the addition of the model singing signal is stopped, and only the accompaniment is reproduced.

[0006]

However, in the above-mentioned conventional configuration, since the model singing signal is recorded only on the R channel, two or more model songs cannot be separated from each other in a duet or chorus song. Was treated as a model song. So, for example, only men sing karaoke,
Even in a part where both a man and a woman sing at the same time in a duet song, addition of a model singing component including both male and female model singing is determined by the result of the microphone volume detection means 103. When there was some kind of microphone sound, there was no model singing signal for the female part that I wanted to be due to duet. For this reason, there was a problem that it was not possible to reproduce a model singing other than a part in a duet song or chorus song.

The present invention solves the above-mentioned conventional problems, and has a function of separately reproducing a plurality of model singing signals, and the presence or absence of a microphone sound changes depending on the content set in advance by a user. In this case, it is an object to provide a karaoke apparatus that continues to reproduce another model singing signal while switching between addition and non-addition of an arbitrary model singing signal.

[0008]

According to the present invention, there is provided a karaoke apparatus for receiving an audio signal and reproducing only an accompaniment signal from the audio signal.
A plurality of auxiliary singing reproducing means for reproducing a plurality of auxiliary singing signals from the audio signal; an auxiliary singing setting means for setting an auxiliary singing signal to be added to the accompaniment signal from the plurality of auxiliary singing signals; Microphone volume detection means for detecting that the level is a volume equal to or higher than a prescribed value, and adding the plurality of auxiliary singing signals to the accompaniment signal based on the setting result of the auxiliary singing setting means and the detection result of the microphone volume detecting means. And an adding means for performing the addition.

With this configuration, the setting result of the auxiliary singing setting means and the input of the input microphone sound are
Due to the detection result being a sound volume having a volume level equal to or higher than the specified value, the accompaniment signal is added and non-added to the plurality of auxiliary singing signals individually. Can switch between addition and non-addition, and provide a karaoke apparatus that continues to reproduce another auxiliary singing signal.

Adding means for determining whether or not to add an optional auxiliary singing signal to the accompaniment signal based on the detection result of the auxiliary singing setting means 5 and an output terminal 23 for outputting the audio signal added by the adding means 6 is there.

Here, DVD (Digita
l Versatile Disc) will be described. DVD
In order to support karaoke applications,
Digital Audio defined by Television Systems Committee
The Dolby Digital Karaoke system is defined in the Compression Standard Rules. In Dolby Digital Karaoke, six channels are defined, and the karaoke left, karaoke right, guide melody, vocal 1, vocal 2, and sound effect signals are recorded on separate channels (if the total is within 6 channels, Multiple channels can be set for guide melodies and sound effects.) Karaoke left and karaoke right correspond to accompaniment signals and are recorded in stereo format. The guide melody is a singing melody signal, and records, for example, the melody of the main melody. The guide melody records the main melody separately from the accompaniment so that beginners can easily sing. Vocal 1 and vocal 2 correspond to two types of model singing signals. In each case, only the model singing signal is recorded, and no accompaniment signal is included. In the sound effect signal, for example, a signal such as a clap, a hand in hand, and a shout is recorded. The auxiliary singing signal includes a model singing signal, a singing melody signal, a sound effect signal, and the like. Hereinafter, the case where the model singing signal is used as the auxiliary singing signal will be described.

In this karaoke apparatus using such a DVD Dolby Digital Karaoke medium, the accompaniment reproducing means 1 first reproduces the karaoke left and karaoke right accompaniment signals. The auxiliary singing A reproducing means 2 reproduces the auxiliary singing signal of the vocal 1. The auxiliary song B reproducing means 3 reproduces the vocal 2. In response to a microphone sound input from a user, the microphone volume detecting means 4 detects the presence or absence of the microphone sound. Microphone volume detection means 4
Is configured to pass a signal of only the audio band using a band-pass filter to the microphone audio as in the conventional example, and to flag whether or not there is an amplitude level equal to or greater than a specified value within a certain period. It can be easily configured by using a method such as When there is a microphone voice, the user instructs the auxiliary singing setting means 5 to switch which auxiliary singing signal by a key input or a remote controller (not shown) (for example, setting to switch only the auxiliary singing A signal) Do). The auxiliary song setting means 5 notifies the adding means 6 of the set contents.

The adding means 6 calculates the result of the detection by the microphone volume detecting means 4 and the result of the setting by the auxiliary singing setting means 5,
When there is a microphone voice, only the auxiliary singing B signal is added to the accompaniment signal and output. On the other hand, when there is no microphone sound,
The auxiliary singing A signal and the auxiliary singing B signal are added to the accompaniment signal and output to the output terminal 23. The output terminal 23 is connected to an amplifier device, a TV device, or the like (not shown), and the output signal can be heard as sound.

According to this structure, the user selects a duet tune by a male, and the auxiliary singing A signal is a male part,
If the auxiliary singing B signal is recorded as a female part, addition and non-addition of the auxiliary singing A signal of the male part are switched according to the microphone sound of the user, but the auxiliary singing B signal of the female part is reproduced. Spelled. Thus, it is possible to switch the voice of only one's own part (in this case, the male part) according to the presence or absence of the microphone voice while performing a duet with the female auxiliary song. It is very convenient for practicing specific parts in duet songs and chorus songs.
Of course, by changing the setting, it is also possible to continue playing the male part and switch only the female part.

The setting contents of the auxiliary singing setting means 5 include a mode in which the auxiliary singing A signal and the auxiliary singing B signal are simultaneously switched as in the prior art when there are two types of model singing. There are four modes: a mode in which only the auxiliary singing A signal is switched, a mode in which only the auxiliary singing B signal is switched, and a mode in which no switching is performed. If it is not desired to add an auxiliary singing signal depending on the presence or absence of microphone sound input in a karaoke performance or the like, this setting may be set to a mode in which nothing is switched. If these modes can be changed not only before playing the song, but also during playback by key input or remote control input, you can change the chorus part in the middle of the song and sing. It is convenient.

The microphone volume detecting means 4 determines that a value obtained by integrating a signal passing through a band-pass filter (not shown) that passes only a signal of, for example, about several tens Hz to several kilohertz is equal to or higher than a specified value. It is determined by the sound volume determination means (not shown) whether or not to indicate. The reason for the integration is to determine whether or not the volume level of the input microphone voice has reached a specified level by an integrated value for a certain period of time because the volume level changes depending on the singing style of the speaker and the surrounding noise level. . It is more preferable that the noise level is detected to change the specified value of the detection level of the audio signal. Further, a microphone insertion detecting means (not shown) for judging whether or not the microphone has been inserted may be provided so that the microphone volume is detected only when the insertion of the microphone is detected. The microphone volume detecting means 4 uses a microcomputer with a D / A converter (hereinafter abbreviated as a microcomputer) for converting into a digital value, reads the volume of the microphone voice as a voltage value at an appropriate sampling interval, and obtains a value for a certain period. There is also a method in which control is performed such that integration is performed. In such a case, if the insertion of the microphone is detected, and if it is determined that there is no microphone, the result of the microphone volume detecting means 4 can be ignored, so that the load on the microcomputer for the microphone volume detecting means 4 can be reduced.

When the addition means 6 switches addition and non-addition of the auxiliary singing signal to the accompaniment signal,
A large change in the accompaniment volume level gives the user a sense of incongruity, so it is desirable not to significantly change the accompaniment volume level. In Dolby Digital Karaoke of DVD, each mix level is set in advance (default value) so that a clip is not caused when an accompaniment signal and an auxiliary singing signal are added. At the time of addition, addition is performed based on the addition setting value so that the addition volume is not too loud to cause clipping, but the volume setting means is provided in the auxiliary singing setting means 5 so that the addition volume distribution can be changed by the user's setting. 9 (not shown), it is necessary to control the volume so as not to clip. It should be noted that if a sound to be added is suddenly output or turned off, an unpleasant sound may be generated as a pop sound. For example, when an analog signal is added to an accompaniment signal and an auxiliary singing signal, an addition volume setting that does not clip even if the addition distribution is set, and a phase setting that prevents addition at different phases are performed. On the other hand, when performing digital signal processing on each of the accompaniment signal and the auxiliary singing signal, and adding digital signals, set the input / output level so that the added signal does not overflow as in the case of analog signals, and switch the addition setting It is effective to perform fade processing on the side of the voice to be added (auxiliary singing signal) so as to prevent occasional pop noise.

Further, the addition means 6 may be configured to add the microphone sound itself. Further, a configuration may be adopted in which the input of the microphone voice is input to the echo unit 14 (not shown), and the result of the input of the microphone voice and the echo is input to the adding unit 6. Alternatively, only the output from the echo unit 14 (the microphone audio input is not directly input to the addition unit 6) may be added to the addition unit 6. Needless to say, it is desirable that the addition means 6 be capable of setting a sound volume for preventing a phenomenon such as clipping even when adding a microphone sound or the like.

(Embodiment 2) FIG. 2 is a block diagram showing a basic configuration of a karaoke apparatus according to Embodiment 2 of the present invention. 24 is an audio input terminal for inputting an audio signal such as a disk reproduction signal, 25 and 26 are microphone A input terminal and microphone B input terminal for inputting microphone sound, 1 is an accompaniment reproducing means for reproducing an accompaniment signal, 2 is an auxiliary singing Auxiliary singing A reproducing means for reproducing the A signal, 3 auxiliary singing B reproducing means for reproducing the auxiliary singing B signal, 7 a microphone A volume detecting means for detecting the presence / absence of microphone sound input from the microphone A input terminal, Reference numeral 8 denotes a microphone B for detecting the presence or absence of a microphone sound input from the microphone B input terminal.
Auxiliary singing setting means 10 for setting the type of auxiliary singing signal to be added to the accompaniment signal based on the detection results of the microphone A volume detecting means 7 and the microphone B volume detecting means 8, and 20 a microphone A volume detecting means 7 Addition means for determining whether or not to add an optional auxiliary singing signal to the accompaniment signal based on the detection result of the microphone B volume detection means 8 and the setting result of the auxiliary singing setting means 10; 27, the sound added by the adding means 20; This is an output terminal for outputting a signal.

As described in the first embodiment, a case will be described in which a DVD is used as a reproduction medium and the specification of Dolby Digital Karaoke is satisfied. In this karaoke apparatus using such a medium, first, the accompaniment reproducing means 1 reproduces the accompaniment signal of the karaoke left and the karaoke right. The auxiliary singing A reproducing means 2 reproduces the auxiliary singing signal of the vocal 1. The auxiliary song B reproducing means 3 reproduces the vocal 2. In the case where the user uses only the microphone A or the microphone B, the first embodiment
The description is omitted because it is the same as the content described above. Here, the case where the user A and the user B have different microphones and input different microphone sounds will be described.

First, the user A sets addition and non-addition of the auxiliary singing signal with and without voice input from his / her microphone A to the auxiliary singing setting means 10 using a remote controller or the like (not shown). Set. Similarly, the user B is set. For example, the user A sets addition and non-addition of only the auxiliary singing B signal, and the user B sets addition and non-addition of only the auxiliary singing A signal. Microphone A volume detection means 7 and microphone B
The volume detection means 8 detects the presence / absence of microphone sound input. The addition means 20 outputs the accompaniment signal when only one microphone sound is input, based on the detection result of the microphone A volume detection means 7, the detection result of the microphone B volume detection means 8 and the setting result of the auxiliary singing setting means 10. Only the auxiliary singing signal of the other party is added and output. However, when the input of the microphone sound is detected at the same time, only the accompaniment signal is reproduced. On the other hand, when there is no microphone voice input at the same time, the auxiliary singing A signal and the auxiliary singing B signal are added to the accompaniment signal and output. With this configuration, user A selects a duet song by male and user B by female, and auxiliary song A
When the user selects a song in which the male part and the auxiliary song B are recorded as the female part, addition and non-addition of the auxiliary song A signal of the male part are switched according to the microphone input of the user A, and the female part The auxiliary singing B signal is also switched according to the utterance of the user B. Therefore, it is possible to switch the sound of only one's own part according to the presence or absence of the microphone sound while performing a duet.

Although the above description has been made in the case of using Dolby Digital Karaoke of DVD having two types of model singing signals (vocal 1 and vocal 2), there are three or more types of model singing signals and the like. In such a case, the configuration can be the same. By adopting a configuration corresponding to three or more types of setting contents of the plurality of auxiliary singing reproducing means and the auxiliary singing setting means 5 for setting which auxiliary singing signal is to be switched, it is possible to easily cope with the setting.

(Embodiment 3) In Embodiments 1 and 2, the auxiliary singing signal has been mainly described using vocal 1 and vocal 2 which are model singing signals. However, as a model singing signal, a normal model singing voice can be included in vocal 1 and a so-called “haunting sound” for vocal 1 can be included in vocal 2. In such a case, the setting is made such that when there is microphone sound, vocal 1 is not added and vocal 2 is added, and when there is no microphone sound, vocal 2 is added and vocal 2 is not added. It is effective if set. For the beat sound, the beat sound is effectively added only when the part where the beat sound is recorded can be effectively sung by adding the beat sound only during the period when the user is singing himself. Sounds better because it is added.

Even when the auxiliary singing signal is a singing melody signal, addition is usually performed only when there is no microphone voice. For example, this corresponds to a case where a guide melody of the main melody is recorded. However, if there is a melody of another part or a performance that effectively excites the main melody is recorded, it may be better to add only when there is a microphone sound.

The same applies to a case where the auxiliary singing signal is a sound effect signal. Sound effects such as clapping sounds and hand-in-hand
It is supposed that it is better to add only when there is microphone sound, but on the other hand, it is better to add only the sound effect of stimulating the economy when the singing does not work well and the warning sound only when there is no microphone sound There is also. Therefore, whether the addition or the non-addition is set depending on the presence or absence of the microphone voice input depends on the content of the auxiliary singing signal recorded on the medium to be reproduced. Therefore, a configuration is desired in which these settings can be freely set by the user and can be changed freely even during the reproduction of music. Of course, it is necessary to be able to set such that the addition of such a sound effect signal or a model singing signal is not required. In the case of this setting, addition of the auxiliary audio signal is not necessary regardless of the presence or absence of the microphone audio input.

(Fourth Embodiment) FIGS. 3 and 4 show a flowchart of a karaoke reproducing method according to a fourth embodiment. FIG.
And FIG. 4 are connected by 1 in the figure. First, in S301, 1 is set to the parameters GV1 and GV2, and initialization is performed so as to output two auxiliary singing signals. Next, in S302, the user inputs which of the two songs is to be sung. Then, in S303, the content inputted by the user in S302 is checked, and when the user inputs to sing song 1,
At 304, the parameter GV1 is set to 0, and the auxiliary singing signal 1 is set not to be reproduced. Further, in step S305, the content input by the user in step S302 is checked. If the user inputs that the user sings the song 2, the parameter GV2 is set to 0 in step S306, and the auxiliary song signal 2 is set not to be reproduced. . Next, in step S307, the process waits until the reproduction is started. If the reproduction is started, the reproduction of the accompaniment signal is first started in step S308. Then, the reproduction of the auxiliary singing signal 1 is started in S310. In step S312, the reproduction of the auxiliary singing signal 2 is started. Then, in S313, it is determined whether or not there is an input from the microphone. If so, in S314, it is determined whether or not the parameter GV1 is 0.
At 15, the reproduction of the auxiliary singing signal 1 is stopped. In addition, S316
It is determined whether or not the parameter GV2 is 0. If it is 0, the reproduction of the auxiliary singing signal 2 is stopped in S317. On the other hand, if it is determined in S313 that there is no input from the microphone, it is determined in S318 whether or not the parameter GV1 is 0. If it is 0, the auxiliary singing signal 1 is determined in S319.
Start playing. Further, in S320, the parameter GV2
Is determined to be 0, and if it is 0, the reproduction of the auxiliary singing signal 2 is started in S321. Then, in S322, it is determined whether or not the music being played has ended. If not, the process returns to S313 to repeat the processing. The reproduction of the singing signal 1 and the auxiliary singing signal 2 is stopped, and the process ends.

It should be noted that after the reproduction of the accompaniment signal is started in S308, during S313 in which the microphone input is detected,
Whether the parameter GV1 is 1 and the parameter GV2 is 1
A determination process for detecting whether or not the auxiliary singing signal 1 is provided only when GV1 is 1 is provided in S309, and a determination process is performed in S311.
S312 to reproduce auxiliary singing signal 2 only when V2 is 1
May be provided. In this configuration, first, S3
In step 09, the value of the parameter GV1 is checked.
Reproduces the auxiliary singing signal 1. The value of the parameter GV2 is checked in S311, and if it is 1, the reproduction of the auxiliary singing signal 2 is started in S312. In this case, the designated auxiliary singing signal is not reproduced until the first microphone input is input, and only the accompaniment signal and the auxiliary singing signal of the partner part are reproduced. After the first microphone input is detected after the user starts singing, the same operation as described above is repeated. Such a configuration is necessary when it is desired to take a configuration that can meet a request that a help voice is not issued from the beginning of the singing when a little progress is made.

(Fifth Embodiment) FIG. 5 is a flowchart of a karaoke reproducing method according to a fifth embodiment. First, S401

In the above description, the case of a karaoke application in which the auxiliary singing signal has a model singing signal, a singing melody signal, and a sound effect signal and a microphone voice is input has been described. . For example,
In the auxiliary singing signal, the instrumental performance of each part of the orchestra is separately recorded, and depending on the presence or absence of microphone sound or input that substitutes it, whether or not to add the model instrumental performance, such as in applications such as instrumental practice,
A similar configuration can be used. Furthermore, the input to the microphone volume detection means is not limited to the input of the user's microphone sound. The same effect can be obtained when an input signal of a musical instrument or the like used by the user is used, or when a microphone sound recorded on a tape device or the like is directly input. In the above description, an example in which the auxiliary singing signal is switched depending on the presence or absence of the microphone sound has been described. DV
When the microphone sound is detected by coordinating the multi-angle function of D, the auxiliary singing signal is switched, the angle setting is changed, and displaying a screen different from a normal one is more interesting. For example, it is possible to provide a karaoke device that makes karaoke more enjoyable, such as, during karaoke of a duet song, a normal landscape image when there is no microphone sound, and an image of the other part is output when there is a microphone sound. it can. In addition, O such as subtitle display
The SD (On Screen Display) display is set to change in accordance with the microphone sound. When the auxiliary singing signal is switched, a message that encourages the user to sing or a display that assists the singing is displayed. It may be configured to output.

As described above, according to the present embodiment, in the karaoke of a duet song or a chorus song, control is performed to switch only a preset auxiliary singing signal depending on the presence or absence of microphone sound input. The other auxiliary singing signals are reproduced regardless of the presence or absence of the input of the microphone sound, and only the set optional singing signal can be switched.

[0042]

As described above, according to the present invention, when a user sings only one song in a song including two types of songs such as a duet, the accompaniment signal and the other auxiliary song signal are always used. The reproduction is continued and it is determined whether or not the user is singing based on the detection of the input signal from the microphone. If it is determined that the user is not singing, the auxiliary singing corresponding to the singing of the user is performed. By playing back the signal, if the user's singing is blocked and interrupted, the auxiliary singing signal is played back to complement the user's song, so even those who are not familiar with singing This has the advantageous effect that the user can sing with the help of the auxiliary singing signal.
