采集输入声音信号，经过系统滤波器以及频谱测量器的处理，在界面一上显示原声音滤波信号的时域和频域波形。界面二则是播放保存在原声音文件中的录音，遇到超时或者停止状况时，停止播放录音。-Collecting the input sound signal, and filter through the system' s processing spectrum measurements, the interface a display of the original sound signal fi

在matlab的UI界面上可以进行录音，并可以实时显示声音波形，还可保存声音。-In the MATLAB UI interface,sound can be recorded, and the wave can be ploted, and you can save the voice.

基于MATLAB的录音程序，使用audiorecorder，可以保存，并有实时波形-MATLAB-based recording procedures, the use of audiorecorder, can be saved, and real-time waveform

首先利用录音工具录制一段语音信号，并人为加入一单频噪声，然后对信号进行频谱分析以确定所加噪声频率，自定相应技术指标，设计一个满足指标的巴特沃斯滤波器进行滤波去噪处理，最后比较滤波前后的波形和频谱并进行分析。-Firstly recording tool to record a voice signal, and artificially added to a single frequency noise, then the signal spectrum analysis to determin

利用matlab进行录音播放，并能够显示声音波形频谱等。(Using MATLAB for recording and playback, and can display sound, waveform, spectrum and so on.)
