Classification: CPC H  G  Y | IPC G  H

Claim 1:
2. The method of using stereo recording to control the flashing of central lamps as claimed in claim 1, wherein in Step c:
the sound signal converting into a light flashing formula comprising a left/right lamp driving algorithm and the formula of said left/right lamp driving algorithm being as follows:

L=A+B; 

R=B+C; 

L−R=(A+B)−(B+C);

L−R=A−C; 

the basis for the signal strength of the left channel signal to be displayed through the left side lamps is: if A−C is a positive number, L will act, and when the positive number is larger, the left side lamps farther to the left side will flash;
the basis for the signal strength of the right channel signal to be displayed through the right side lamps is: if A−C is a negative number, then R will act, and when the negative number is larger, the right side lamps farther to the right side will flash;
in the above, L means that one or more left side lamps flash;
R means one or more right side lamps flash;
A is the sound source of the left area;
B is the sound source of the central area;
C is the sound source of the right area.
