Stereo Recording Control for Central Lamp Flashing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current music and lighting interactive devices rely on fixed preset programs, leading to inconsistent rhythm and flashing frequencies, resulting in a poor sensory experience for audiences and inadequate focus on the lead singer, especially in live performances.
Innovation Solution
A method using stereo recording to control central lamp flashing, where left and right channel microphones record sound sources and convert sound signals into light flashing formulas, utilizing algorithms to drive central, left, and right lamps to create synchronized and staggered flashing patterns that align with music rhythm and voice, enhancing the interaction between the lead singer and audience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If fixed preset programs are used to control lighting, then the lighting system is simple to operate, but the rhythm consistency between music and lighting deteriorates
Solution Approach 1:
The system uses real-time audio signal analysis to detect music rhythm and automatically adjusts lighting flashing frequency accordingly. The audio signal is processed to extract rhythm information, which then feeds back to control the lighting system, ensuring consistent rhythm between music and lighting without manual intervention.
Solution Approach 2:
The lighting system automatically analyzes the audio signal itself to determine flashing parameters, eliminating the need for external preset programs. The system serves itself by extracting rhythm information directly from the music signal and using it to control lighting, achieving both operational simplicity and rhythm consistency.
2Ease of manufacture
If general lighting control based on volume and frequency is used, then the lighting system is easy to implement, but the focus on lead singer deteriorates
Solution Approach 1:
The system applies different processing weights to different audio channels, with special emphasis on the central channel where lead singer vocals are typically located. The central channel signal is given higher weight in the flashing frequency calculation, ensuring that lead singer movements and vocals receive focused lighting attention while maintaining simple system implementation.
Solution Approach 2:
The audio signal is segmented into different channels (left, center, right) and processed separately. The central channel is specifically identified and given priority in controlling the lighting, allowing the system to focus on the lead singer while keeping the overall system simple to implement.
3Adaptability or versatility
If too many music tracks are processed with preset programs, then the system can handle diverse music, but the arrangement time increases
Solution Approach 1:
The system automatically analyzes each music track's audio signal in real-time to extract rhythm information, eliminating the need for manual arrangement of preset programs for each track. This self-service approach allows the system to adapt to any music track without increasing arrangement time, as the automation handles the adaptation process dynamically.
Solution Approach 2:
The system dynamically changes lighting parameters (flashing frequency, intensity) based on real-time analysis of the music track's audio signal characteristics. This allows the system to adapt to diverse music tracks by automatically adjusting parameters according to the specific rhythm and intensity of each track, without requiring pre-arranged programs.
4Adaptability or versatility
If central lamp flashing frequency is increased to match lead singer rhythm, then the interaction between viewer and lead singer is improved, but the complexity of light control algorithm increases
Solution Approach 1:
The system uses feedback from the central channel audio signal to dynamically adjust central lamp flashing frequency. The audio signal from the central channel is processed to extract rhythm information, which directly controls the flashing frequency, creating a simple yet effective feedback loop that enhances viewer-lead singer interaction without requiring complex algorithms.
Solution Approach 2:
The central lamp flashing frequency is made dynamic, automatically adjusting to match the rhythm of the lead singer's performance in real-time. This dynamic control is achieved through simple real-time audio signal analysis of the central channel, allowing the system to adapt to varying performance intensities without complex pre-programming.

AI summary
A method of using stereo recording to control the flashing of central lamps includes the steps of: providing left and right channel microphones in a stereo sound source venue or electronic device, and recording the plural sound sources generated by the left area, central area and right area of the stereo sound source, then storing the recorded analog signal in an audio signal sampling unit of a signal processing device, and then converting the sound signal into a light flashing formula to obtain a light flashing parameter value. According to the light flashing parameter value of the operation control unit, the left side lamps, the central lamps and the right side lamps respectively form staggered flashing, so that the flashing light set produces light changes corresponding to the music rhythm and vocals.
