偶然脑子发热心血来潮，想要做一个声音可视化的系列专题。这个专题的难度有点高，涉及面也比较广泛，相关的FFT和FHT等算法也相当复杂，不过还是打算从最简单的开始，实际动手做做试验，耐心尝试一下各种方案，逐步积累些有用的音乐频谱可视化的资料，也会争取成型一些实用好玩的音乐可视器项目。

RGB 5050灯带主要特点：
1、可随意弯曲，可任意固定在凹凸表面；
2、每隔3颗LED灯即可组成一回路；
3、体积小巧，颜色丰富；
4、使用室内低压、户外高压，套管以及滴胶防水。
参数及应用
1、每三个LED可以沿着上面切线任意截断，不损坏其它部分
2、由印制电路板组成，背面带双面胶，用于粘贴
3、体积小。有多种颜色可供客户选择
4、用于透明或非透明材料的四周点亮、局部照明
5、用于用于路径和轮廓标志、广告、电视背景墙、室内吊顶
6、每卷的标准长度：5m，表面采用滴胶或套管处理。
7、每卷灯的数量为：300pcs软光条的宽度：10mm
8、工作电压：直流电压12V、交流220V
9、LED规格：采用超高亮3528/5050贴片LED
10、发光颜色：红／黄／蓝／绿／白
