1. A method of using stereo recording to control the flashing of central lamps, comprising the steps of:
a: providing left and right channel microphones in a stereo sound source venue or electronic device, and recording multiple sound sources generated by the left area, central area and right area of said stereo sound source, and then storing the recorded analog signal in an audio signal sampling unit of a signal processing device;
b: using an audio signal amplifier to amplify the analog signal stored in said audio signal sampling unit and using an analog-to-digital converter to convert the analog signal into a digital signal;
c: using an operation control unit to capture the digital signal, and then separating the digital signal into left and right channel signals, then, using software calculation to enhance the digital signal 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 the 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 central lamp driving algorithm and the formula of said central lamp driving algorithm being as follows:

N1=(A+B)−(B+C)=AB+2B+AC+BC=2A+4B+2C; 

multiplying the above result by itself

N=N1×N1=(2A+4B+2C)×(2A+4B+2C)=4A+16B+4C; 

the basis for the signal strength of a central channel signal to be displayed through a central lamp being: because the value of B is much larger than the values of A and C, the action of B can directly drive said central lamp N to act, where
N means that one or more central lamps flash,
N1 refers to the operation parameter of central lamp,
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: said operation control unit transmitting control commands to a left/right lamp driving unit and a central lamp driving unit respectively according to said light flashing parameter value; and
e: using said left/right lamp driving unit to drive a left side lamp and a right side lamp of a flashing light set to flash, and using said central lamp driving unit to drive a central lamp of said flashing light set to flash, so that said flashing light set generates light changes corresponding to the music rhythm and human voice as said left side lamp, said central lamp and said right side lamp form staggered flashing.
