Press, in order to pursue a higher level of sensory enjoyment, the hearing brought by pure music rhythm is difficult to meet people's sensory needs, so more and more music equipment is designed to give more visual experience to provide The audience adds more different atmospheres in the process of listening to the music. However, most of the music and lighting interactive devices are controlled by the lighting manufacturer through the fixed program preset by the system. The specific method is to follow the performance of the music in the program in advance, or through the style of the music Adjust the color and brightness of the light according to the rhythm, and it can be broadcast at the same time when the show is on.

However, this pre-set fixed program does not make music and The combination of lights achieves the most suitable effect, but at the same time, the rhythm of the music and the flashing lights may not be in harmony, resulting in poor sensory experience for the audience and reducing the music atmosphere of the scene. In addition, when there are too many music tracks, the lighting manufacturer will spend more time on arrangement, so it will not provide exclusive lighting interaction for each track. What's more, at present, lighting manufacturers use the two parameters of sound volume and music frequency to switch the position of the light, and adjust the color and brightness of the light accordingly. However, adjusting the above two parameters will cause the light interaction to be too disordered, resulting in a bad experience. Returning to the origin of music and lighting, people feel that the combination of music changes is due to the rhythm in the music. The rhythm is the embodiment of the time, sequence, and strength of the music. Only through the rhythm can the music be carried out in an orderly manner. Optimized experience.

Step 42: After using the analog sound signal stored in the sound source sampling unit to amplify the signal through a sound source amplifier, the channel balance unit makes a comparison based on the volume difference between the sounds recorded by the left and right channel microphones, and according to the The volume difference is compensated by addition or multiplication for the sound of the smaller channel, so that the volume of the two channels is averaged, and then the analog sound signal is converted into a digital sound signal by an analog/digital converter.

Regarding the above-mentioned compensation calculation method for adding or multiplying the sound of the smaller channel for the volume difference, for example, when the ratio of the volume value recorded by the left channel microphone 11 to the volume value recorded by the right channel microphone 12 is 6 to 4, it is obvious that the sound of the right channel microphone 12 is relatively small. At this time, the channel balance unit 23 divides the volume values of the two to obtain a ratio of 1.5 to 1, and then conducts a calculation for the low sound of the right channel microphone 12. Compensation operation of 1.5 times of multiplication, so that the volume value of the right channel microphone 12 is amplified from the original 1 to 1.5, so it can be 1.5 to 1.5 with the ratio of the left channel microphone 11 and the right channel microphone 12, and convenient To achieve the purpose of volume balance adjustment. In addition, the channel balance unit 23 can also perform an additive compensation operation on the difference between the right channel microphone 12 and the left channel microphone 11 with the smaller sound, so that the ratio of the left channel microphone 11 to the right channel microphone 12 Reaching 1 to 1, and this approach is also within the protection scope of the present invention.

Step 43: Use an arithmetic control unit to capture the digital audio signal, then separate the digital audio signal into left and right channel signals, and perform a process according to the recorded signal strengths of the left channel signal and the right channel signal respectively. The sound signal is converted into a light flashing calculation formula to obtain a Light flashing parameter value.

Step 44: The arithmetic control unit transmits control commands to a left/right lamp driving unit and a central lamp driving unit respectively according to the light flickering parameter value.

Step 45: Use the left/right lamp driving unit to drive a left lamp and a right lamp in a flashing lamp group to flash; use the central lamp driving unit to drive a central lamp in the flashing lamp group to flash , as the left lamp, the central lamp and the right lamp form interlaced flashing, the flashing lamp group is formed to produce light changes corresponding to the music rhythm and the human voice.

In the above-mentioned step 43, the formula for converting the sound signal into light flickering further includes a driving algorithm for left/right lamps and a driving algorithm for central lamps.

The formula of the above left/right lamp driving algorithm is as follows:

L=A+B; this formula means to ignore the sound source C in the farthest right area

R=B+C; this formula means to ignore the sound source A in the farthest left area

L-R=(A+B)-(B+C);

L-R=A-C;

If A-C is a positive number, then L will act, and when the positive number is larger, the lamps on the left side of the complex will flicker;

If A-C is a negative number, R will act, and when the negative number is larger, the lamps on the right side of the complex number will flicker;

Above, L means that one or more lights on the left flicker;

R means that one or more lights on the right side flicker;

A is the sound source of the left area;

Series B is the sound source of the central area;

C is the sound source of the right area.

The formula for the N driving algorithm of the above-mentioned central lamp is as follows:

N=(A+B)-(B+C);

=AB+2B+AC+BC;

=2A+4B+2C;

Multiply the above result by itself

N=(2A+4B+2C)×(2A+4B+2C);

=4A+16B+4C;

Because the value of B is much larger than the values of A and C, the action of B can directly drive the central lamp N to operate;

N means that one or more central lamps flicker;

A is the sound source of the left area;

Series B is the sound source of the central area;

C is the sound source of the right area.

The main feature of the present invention is that after the sound source sampling unit 21 of the signal processing device 2 has stored the analog sound signals recorded by the left channel microphone 11 and the right channel microphone 12, the signal is amplified by the sound source amplifier 22 of the signal processing device 2 Afterwards, compare according to the volume difference of the sound recorded by the left and right channel microphones (11, 12) through the channel balance unit 23, and carry out the compensation operation of addition or multiplication for the sound of the smaller channel according to the volume difference, so as to Make the volume of the two channels form an average state, and then follow up with an analog/digital converter to convert the analog sound signal into a digital sound signal, and the operation control unit transmits the light flashing parameter value respectively When the control command is sent to the left/right lamp drive unit and the central lamp drive unit, the correct flashing signal can be obtained, so as to avoid the lamps on the corresponding side with low sound not receiving the control command for a long time and flashing, which will cause the lamp signal to be different.
