编程实现帧封装。帧封装只是在数据的头和尾上加特定的二进制数据，可以直接用读写二进制文件的方式读出来，然后把该加的头尾写进去就行了。 -Programming frame package. Encapsulated only in the data frame the head and tail add a specific binary data, you can read and write binary files directly read out the way and the

简单的基于门限值的语音端点检测。先将数字化的语音信号封装成帧，利用最大的帧幅值乘以一个比例因子得到门限值-Simple threshold-based voice end point detection. First，framing the digital voice signal , then using the maximum amplitude to multiply a frame scale factor to get threshold
