従来例について説明する。(Configuration of conventional example and its problems) In a singing practice device using an 8-track recorder that uses conventional audio multiplexed tape, the output balance of the singer's singing and accompaniment music is divided into several parts, and the output balance is adjusted individually. He also used a microphone to sing along with the music, and as he improved, he gradually reduced the singer's audio signal until he could sing with only the accompaniment music. The conventional example shown in FIG. 1 will be explained below.

Obtained by b. Each signal is sent to a regenerative amplifier 2a.
, 2b [processed and amplified], and the output of each amplifier is connected to the audio multiplex balancer 15. Here, the balance between the singer's audio output and the accompaniment music output is adjusted. 1c is a microphone, and the microphone amplifier 3
After being amplified, the signal is mixed together with the balance-adjusted tape signal through an echo circuit 4, amplified by a power amplifier 5, and amplified by a speaker 6.
この場合、手本となる歌手の歌唱と自分の歌唱との差、

After passing through the low-pass filter and waveform shaping circuit installed in the channel signal system and microphone signal system,
AND of the above two signals, take out NAND, AND
The circuit configuration is such that the output is rectified and charged, and the NANDAND output is discharged to obtain a voltage according to the degree of matching of the two signals, and this can be objectively evaluated by displaying it using a display means such as an LED. .

Therefore, the effects of practice can be seen early. Further, the present invention can provide a device with a small number of components, a low cost, and a large singing practice effect.
