采集声卡的信号，并对声音信号进行fft分析，对如何获得声卡信号和简单的信号处理有帮助-it s a very good sample of processing sound card signal

该程序主要是对语音信号进行分析，采用FFT变换求取信号的幅值与频率，然后与以存储模版进行比较，判断信号是否正常。-The process is essentially the voice signal using the FFT algorithm to strike a signal amplitude and frequency, and then to store the template to determine whether the signal is normal.

自己制作的信号生成与信息处理模块，对生成的信号进行滤波，采样FFT然后分析功率谱,输出高通信号-Signal generation and produce their own information processing module, a signal generated by filtering, sampling FFT and then analyzes the power spectrum of the output high communication No.
