Abstract
The conversion of audio signals into light usually involves converting the frequency information of the audio signals into the intensity,color,or brightness changes of the light signals,resulting in the phenomenon of insufficient color and intensity of the light signals and display delay.A control method for audio acoustic signal adaptive mapping of optical signal technology is proposed in this paper.In the preprocessing stage,it extracts the spectral characteristics of the spectral energy and spectral center,focusing on analyzing various characteristics of pitch,timbre,rhythm and dynamic changes in audio signals.According to the mapping of the spectral center of the audio signals onto the color spectrum,different frequencies correspond to different colors,and the brightness of the light is controlled according to the spectral energy level.The results show that sound-light adaptive mapping technology based on STFT algorithm has significant advantages in speed and effectiveness of audio frequency mapping color display,verifying the effectiveness of the proposed color mapping and display delay strategy.关键词
