对指定音频信号进行高通滤波处理，并输出指定文件，滤波采用双线性变换法-Designated high-pass filtering the audio signal processing, and outputs the specified file, filtering using bilinear transform

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.

数字信号处理中简单的音频特效处理，回声，变调、低通滤波、高通滤波-Digital signal processing simple audio effects processing, echo, pitch, low pass, high pass filter
