安卓实现仿照微信录制语音功能，代码案例，可直接在eclipse下运行(Android's recording function)

实现语音识别波形，通过录一段语音，用matlab识别波形并对语音信号进行处理(The waveform of speech recognition is realized. By recording a speech, the waveform is recognized by MATLAB and the speech signal is processed)

1.通过本实验掌握数字全息实验原理和方法； 2.通过MATLAB编程，对实验数字全息图进行数据处理，达到提高再现像质量和方便提取有用信息的目的； 3.用空域滤波方法消除零级像； 4.理解波前记录与再现。(1. Master the principle and method of digital holography experiment through this experiment; 2. Through MATLAB programming, the experimental digital
