代码说明：

  1）语音信号的采集 2）语音信号的频谱分析 3）设计高通、低通数字滤波器和画出其频率响应 4）用滤波器对信号进行滤波 5）比较滤波前后语音信号的波形及频谱 6）播放原始语音信号 7）实现快放、慢放功能 8）实现回音音效效果 9）实现变高音、低音效果 10）设计GUI系统界面 (1) voice signal acquisition 2) speech signal spectrum analysis 3) design high-pass, low pass digital filter and plot its frequency response 4) filtering the signal with a filter 5) to compare the before and after filtering the speech signal waveform and spectrum 6) Play the original voice signal 7) to achieve fast, slow function 8) to achieve an echo sound effect 9) to achieve change treble, bass 10) GUI system interface design)
