摘要：Synesthesia effect between music and color is a researching direction which is concerned much. The problem of mismatching between music playing and color had always existed in applications. On the basis of researching music and color, colors which are corresponding to various chords respectively are determined, and the frequency spectrum analysis on chords is performed. The real-time frequency domain transformation to time domain audio signal being played is carried out. The closest chord to audio signal being played can be identified via comparison between a chord spectrum and the spectrum of audio signal being played, and the color corresponding to the audio signal is determined. To improve the accuracy of recognition the method is investigated with which wavelet transform is adopted to de-noise processing of audio signal. Through tests on the audio experiment platform, color mixed effect test, optimization of the audio signal processing parameters, and processing time sequence scheming have been performed. A novel audio player is developed in application to realize the optimal RGB-LED mixed light which automatically presents matching color effect for arbitrary music being played. The research can reveal relationships between music and color from the perspective of frequency spectrum, promote the development of the color music, which has broad application prospects in urban landscape, stage lighting, and psychotherapy.
