用同态滤波方法（倒谱）解决回声干扰问题。给出了一句语音，并在此信号上叠加回声干扰，通过倒谱的方法将信号和回声的冲击响应分开。-using the same state filtering method (cepstrum) Echo solve the interference problem. Given a voice, and in this echo superimposed on the signal interference, through cepstrum approach wo

可以产生16bits和24bits的正弦信号，多个正弦信号的叠加以及扫频信号，所有信号都生成为wav文件。可以控制信号的幅度，频率和相位。自己写的，如果有问题，请小窗联系。-Can generate 16bits and 24bits sinusoidal signal, the superposition of multiple sinusoidal signals, as well as sweep signal, all signals gave birth to a wav file.
