Abstract

PROBLEM TO BE SOLVED: To enable a singer to optionally vary the sound volume of a melody singing voice or submelody singing voice outputted in the form of MPEG(Moving Picture Expert Group) for communication KARAOKE, etc. SOLUTION: When a music number is inputted through an input part 1, a control part 3 communicates with a host computer through an attached communication device to receive and record music information on the specified music number and also read it out. Then MIDI data is inputted to a MIDI decoder 5 and decoded into an L-instrument musical sound signal and an R-instrument musical sound signal, which are converted by D/A conversion parts 6L, 6R into analog signals and inputted to mixing parts 10L, 10R. The MPEG data is inputted to a MPEG decoder 7 and decoded into a main melody and a submelody singing voice signal; and the main melody signal is outputted over an L channel and the submelody signal is outputted over an R channel. They are attenuated by attenuators 8L, 8R and converted by D/A conversion parts 9L, 9R into analog signals, which are mixed by the mixing parts 10L, 10R with the L-, R-instrument musical sound signals, so that the mixture signals are outputted. The attenuation quantities of the attenuators 8L, 8R are varied through the operation of a main and subordinate operation part 4.

It is output in each channel and applied to the attenuator 8L or 8R, respectively. For the attenuators 8L and 8R, pressing the “main” side of the main / sub operation unit 4 increases the value of the attenuator 8R, lowers the level of the auxiliary melody singing voice signal, and the “sub” of the main / sub operation unit 4 Pushing the side increases the value of the attenuator 8R and lowers the level of the main melody singing voice signal. Accordingly, the volume ratio of the main and side singing voices can be adjusted so that the singer can easily sing his / her own voice depending on whether the singer is practicing the main melody part or the sub melody part. Alternatively, if the “main” side of the main / sub operation unit 4 is pressed, the value of the attenuator 8L decreases and at the same time the value of the attenuator 8R increases, and if the “sub” side of the main / sub operation unit 4 is pressed, the attenuator 8R
The value of the attenuator 8L may be increased at the same time as the value of is decreased. The signals from the attenuators 8L and 8R are D
Converted to an analog signal by the / A converter 9L or 9R,
The main melody singing voice signal is input to the mixing section 10L, and the sub-melody singing voice signal is input to the mixing section 10R, respectively mixed with the instrumental sound signal, amplified by a required amplifier, the instrumental sound is stereo, and the singing voice is L. From (left) to the main melody, R (right)
To output the melody as a sound.

音響で出力される。In the case of FIG. 2, the processing of instrumental sound data is the same as that of FIG. The main melody singing voice data of the singing voice read from the recording medium 2 is decoded by the MPEG decoder 11 into an L-main melody singing voice signal and an R-main melody singing voice signal, and the decoded signals are respectively attenuators 12L or
When inputting to 12R and pushing the main / sub operation part 4 to the "sub" side, the values of the attenuators 12L and 12R increase and the signal level is narrowed down, and the analog signal is respectively converted by the D / A converter 13L or 13R. And the L-main melody singing voice signal is input to the mixing unit 17L, and the R-main melody singing voice signal is input to the mixing unit 17R. The sub-melody singing voice data from the recording medium 2 is decoded by the MPEG decoder 14 into an L-sub-melody singing voice signal and an R-sub-melody singing voice signal, and the decoded signals are input to the attenuators 15L or 15R, respectively. And the attenuator when the main / sub operation unit 4 is pushed to the "main" side
The values of 15L and 15R are increased to reduce the signal level, and the D / A converters 16L and 16R respectively convert the analog signals, and the L-submelody singing voice signal is mixed into the mixer 17L.
Then, the R-submelody singing voice signal is input to the mixing section 17R. If the “main” side of the main / sub operation unit 4 is pressed, the values of the attenuators 12L and 12R decrease and at the same time the values of the attenuators 15L and 15R increase, so that the “sub” side of the main / sub operation unit 4 is pressed. If the attenuators 15L and 15R decrease in value,
The values of 12L and 12R may be increased. The output signals of the mixing section 10L and the mixing section 10R are amplified by a required amplifier, whereby the volume ratio of the main melody singing voice and the auxiliary melody singing voice is arbitrarily changed by the operation of the singer, etc. Both voice and side melody singing voice are output in stereo sound.
