The invention discloses a music rhythm atmosphere lamp control method and system, an atmosphere lamp and a vehicle thereof, and the method comprises the steps: collecting audio data, and carrying out the Fourier transformation of the audio data; obtaining the maximum value and the minimum value of the Fourier transform function in the current sampling period, and calculating the amplitude difference of the current sampling period; according to a preset first threshold value and a preset second threshold value, the amplitude difference is compared with the first threshold value and the second threshold value, and the adjusting speed of the current atmosphere lamp is classified according to a comparison result; and setting filtering lengths, determining corresponding different sampling numbers according to different filtering lengths, obtaining a corresponding maximum amplitude value and a corresponding frequency, and controlling the atmosphere lamp to display the color and brightness corresponding to the current audio signal. According to the invention, the flickering of the atmosphere lamp can be matched with the rhythm function of music, and the phenomenon of frequent color flickering or too slow color brightness change is prevented.

    本发明公开了一种音乐律动氛围灯控制方法、系统、氛围灯及其车辆,方法步骤包括:采集音频数据,将音频数据进行傅里叶变换;获取当前采样周期内傅里叶变换函数的最大值和最小值,计算当前采样周期的幅值差;根据预设的第一、二阈值,将幅值差与第一、二阈值进行对比,根据对比结果对当前氛围灯的调节速度进行分类;设定滤波长度,根据不同滤波长度确定对应不同的采样个数,并获取对应的振幅最大值和对应的频率,控制氛围灯显示当前音频信号对应的颜色和亮度。本发明能够使氛围灯的闪烁与音乐的律动功能相匹配,防止出现颜色闪烁频繁或颜色亮度变化过慢的现象。
