In step 400, the Karaoke recording sound quality improvement device receives the voice input from the microphone. The voice may be a voice (vocal) vocalized in accordance with the accompaniment music corresponding to the song selected by the karaoke user. In particular, in the present invention, the micro-input voice is used to synthesize the accompaniment music in step 410. [

In step 410, the karaoke sound quality improving apparatus generates a synthesized voice by synthesizing the stored accompaniment music and the voice received in step S400.

The accompaniment music corresponding to the song selected by the singer who is the karaoke user is stored in a separate storage device in the karaoke recording quality improvement device. If the accompaniment music corresponding to the song selected by the singing user is not stored in the storage device, the accompaniment music data is requested and received by the server storing the accompaniment music, stored in the internal storage device, Can be output.

On the other hand, the accompaniment music used to generate the synthesized voice is not a noise-free signal but an accompaniment music stored in a separate storage device in a karaoke recording sound quality improvement device, not a accompaniment music that is output by a speaker and micro-received.

In operation 420, the karaoke sound quality improving apparatus receives the synthesized sound generated in operation 410.

The voice may be a voice (vocal) vocalized in accordance with the accompaniment music corresponding to the song selected by the karaoke user. In particular, in the present invention, the micro direct input voice is used in step 510.

In step 510, when the voice of the micro singer is directly inputted, the speaker output sound outputted from the speaker is also micro-input, so that the sound of less than a certain decibel is removed to remove the speaker output sound.

The voice inputted directly to the microphone by the singer has a decibel (dB) of a certain size or more, but the accompaniment music and voice outputted by the speaker are not more than a certain size. At this time, it is preferable that the predetermined size is determined in proportion to the magnitude of the voice input directly to the microphone by the singer. This is because the accompaniment music and voice outputted to the speaker in proportion to the voice input directly to the microphone become larger or smaller.

Therefore, by filtering the sound of a certain size or less from the sound coming through the microphone, the speaker output sound outputted by the speaker is removed, and only the voice inputted directly to the microphone by the singer can be used for synthesizing with the accompaniment music in step 520 without noise .

In step 520, the karaoke sound quality improving apparatus generates a synthesized voice by synthesizing the accompaniment music stored in step 510 and the voice with noise removed in step 510.

The accompaniment music corresponding to the song selected by the singer who is the karaoke user is stored in a separate storage device in the karaoke recording quality improvement device. If the accompaniment music corresponding to the song selected by the singing user is not stored in the storage device, the accompaniment music data is requested and received by the server storing the accompaniment music, stored in the internal storage device, Can be output.

On the other hand, the accompaniment music used to generate the synthesized voice is not a noise-free signal but an accompaniment music stored in a separate storage device in a karaoke recording sound quality improvement device, not a accompaniment music that is output by a speaker and micro-received.

In step 530, the karaoke sound quality improving apparatus receives the synthesized sound generated in step 520. [

Referring again to FIG. 2, if steps 500 through 520 are performed in the song recording device 240, step 530 may be omitted.

However, if steps 500 through 520 are performed in the song providing apparatus 200, the synthesized sound generated in step 520 is transmitted from the song providing apparatus 200 to the song recording apparatus 240, so that step 530 is required.

In step 540, the karaoke sound quality improving apparatus transmits the synthesized sound received in step 530 to a separate server.

The synthesized sound having improved sound quality transmitted to the server can transmit a URL address that can be downloaded to a karaoke user through a short message service (SMS), a multi-media message service (MMS), or a messenger app. When the user accesses the URL address, the user can download the song that is stored in the server.
