DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a karaoke apparatus, and more particularly, to a karaoke apparatus having a function of adding an acoustic effect such as an echo to karaoke accompaniment music or a singer's voice signal input from a microphone. It concerns the device.

[0002]

2. Description of the Related Art A karaoke apparatus generates an audio signal of accompaniment music by appropriately processing karaoke data of a requested karaoke song. Then, the accompaniment music audio signal is amplified by an amplifier or the like and output to a speaker. On the other hand, the singing audio signal input from the microphone by the singer is output to the above-described amplifier or another type of speaker for accompaniment music output through another signal amplification path. In addition to such basic functions, the karaoke apparatus has a sound effect adding function of improving the entertainment of karaoke by adding a sound effect such as an echo to an audio signal.

The sound effect adding function adjusts parameters such as reverberation time of echo and enhancement and reduction of treble and bass from a control panel or a remote control device of the karaoke apparatus in the same manner as volume adjustment or the like. A desired sound effect can be added by preparing a plurality of operation modes in which the adjustment values are specified in advance and selecting a desired operation mode from among them. For some karaoke songs, the operation mode is described as a control signal in the corresponding karaoke data. in this case,
A sound effect is automatically added at the time of performing the music.

[0004]

SUMMARY OF THE INVENTION It is not possible to obtain sound effects suitable for the music style of each song simply by adding sound effects blindly without considering the characteristics of artists such as singers or performers of songs or original songs. Not only is it impossible, but sometimes the sound effects are annoying. Only when a sound effect that matches the style of the song is added can the singer sing the karaoke song more comfortably and can greatly excite the venue.

[0005] In order to appropriately add sound effects according to the style of karaoke music, it is necessary to appropriately adjust appropriate sound effect parameters. However, for that purpose, a complicated adjustment operation must be performed. In addition, appropriate knowledge of sound effects is required. It is unlikely that ordinary users have such specialized operations and knowledge,
It is hard to say that advanced sound effect functions are being used effectively. Even in a method of selecting a favorite mode from a plurality of preset operation modes, a special operation other than the music selection operation in the karaoke apparatus is forced. Also, specialized knowledge is still required. The degree of the sound effect cannot be known unless the sound after the addition processing is actually output. Therefore, the adjustment operation or the mode selection operation must be repeated many times, and the karaoke use time is wasted.

On the other hand, the method of describing information for controlling the sound effect in the karaoke data does not require an operation for adjusting the sound effect parameter. However, only some of the tunes are supported, and other karaoke tunes require manual adjustment as described above. Also, if all karaoke songs are to be compatible with automatic control, it is necessary to create karaoke data in which a large number of songs including past songs are specified in detail, including adjustment values of sound effect parameters. Since it takes a lot of time to create the karaoke data, it is difficult to quickly supply additional karaoke data in response to the constant release of new songs.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a karaoke apparatus capable of adding a sound effect that matches each karaoke song without adjusting by the user or adding control information for the sound effect to the karaoke data.

[0008]

According to the present invention, there is provided a karaoke apparatus having the following requirements (1) to (3).

(1) The karaoke data of the requested karaoke music is processed to amplify the accompaniment music audio signal and output it to the speaker, and amplify the singing audio signal from the microphone and output it to the speaker.

(2) Each karaoke data is accompanied by an artist code indicating the original song artist of each song. A sound effect designation table in which sound effect designation information, which is control information for defining the operation mode of the sound effect adding means, is directly or indirectly associated with each of a number of artist codes is created and stored. ing.

(3) In processing the karaoke data of the requested music, the artist code is obtained from the corresponding karaoke data, and the sound effect designation information corresponding to the artist code is taken out from the sound effect designation table to obtain the sound result. Give to additional means.

Further, the sound effect adding means is interposed in each of the accompaniment music audio signal and the singing audio signal, and the sound effect designating information individually defines an operation mode in the two systems of sound effect adding means. Is also good.
