一般彩色音乐装置的原理,大都是采用频率分割的方法,用音乐信号频谱中的不同频段分别去控制几组灯光闪烁。这样,当音乐信号出现时,灯光装置随着信号的频谱和幅度来变化彩色和光强,给人们的艺术感受是深刻的。但是,彩色音乐装置有原理性的缺点。这种装置的声光转换关系,是按照既定的频谱——彩色规律机械地进行着“翻译”。例如, The general principle of color music devices, mostly using frequency segmentation method, using different frequency bands in the music signal spectrum, respectively, to control several groups of lights flashing. In this way, when the music signal appears, the lighting device changes the color and light intensity according to the spectrum and amplitude of the signal, which impresses the people’s artistic feelings. However, color music devices have a fundamental disadvantage. The acousto-optic conversion of this device is mechanically “translated” in accordance with the established spectrum-color law. E.g,
