大学生电子竞赛论文报告-音频信号分析仪。主要利用频谱分析原理，频谱分析是把信号的能量用频率的函数显示出来-Undergraduate Electronic Thesis Competition Report- audio signal analyzer. The main principle of the use of spectrum analysis, spectrum analysis is used to signal the frequency of the energy functi

通过8ps59芯片控制 12 路灯，模式分为两种：一种为无音频 信号时，12 路灯组合出 5 种不同规律闪烁灯光 另一种是有音 频输入时 12 路灯由音频节奏伴随闪烁，貌似单路频谱-12 lamps by 8 ps59 chip control, model is divided into two kinds: one is without audio Signal, 12 street lamp combination rule of five different flashing

编写fft程序，用51单片机实现分频与输出，制作点阵LED音频谱，源程序由 sishwuh提供。-Making a lattice LED audio spectrum

这是STM32F103实现音乐频谱的程序，绝对可以实现功能，做过实物，测试效果很好。(This is STM32F103 to achieve music spectrum procedures, absolutely can achieve functions, has done physical, testing results are very good.)
