1. A method of using stereo recording to control the flashing of multiple lamps, comprising the steps of:
a. performing a recording operation on a plurality of sound position sources generated by a stereo sound source venue or an electronic device, and storing the recorded analog signal in an audio signal sampling unit of a signal processing device;
b. amplifying the analog signal stored in the audio signal sampling unit by an audio signal amplifier, and then converting the amplified analog signal into a digital signal by an analog-to-digital converter;
c. using an operation control unit to capture the digital signal, and then separating the digital signal into left and right channel signals, then, enhancing the signals through software calculation according to the recorded signal strength of the left channel signal and the right channel signal respectively and based on the sound source recorded in a central area by the left and right channels, and then converting the sound signal into a light flashing formula to obtain a light flashing parameter value;
the sound signal converting into a light flashing formula comprising a left/right lamp driving algorithm and the formula of the 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 left side lamps is: if A−C is a positive number, then 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 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;
d. the operation control unit transmitting control commands to a left/right lamp driving unit and a central lamp driving unit respectively according to the light flashing parameter value; and
e. using the left/right lamp driving unit to drive the left side lamp and the right side lamp of a flashing light set to flash and using the central lamp driving unit to drive a central lamp of the flashing light set to flash, so that the flashing light set generates light changes corresponding to the music rhythm and human voice as the left side lamp, the central lamp and the right side lamp form staggered flashing.
