G.721算法的matlab编程，自己编写的，程序没任何问题。另一部分是G.721算法的BP改进，SNR提高不大！-G.721 algorithm matlab programming, I have written, the program did not any problems.

因为 现在的有关音频编程的资料很少 多是商业的 这个并没有什么算法实现 仅提供一个框架 为编程方便 主要有3个类 分别实现 音频文件管理 波形文件图形绘制 算法分析-Because of little information about audio programming mostly commercial and there is no algorithm that provides only a framework for programming convenience Th

该程序主要是对viterbi语音算法进行简单的编程，具体算法可以自己看文章-The program is mainly on the Viterbi speech algorithm for simple programming, the specific algorithm can look at the article
