说明： 包括三个文件夹一个简易说明文件其中
1. pc为定点化的源代码，非浮点代码喔，还包含两个工程代码，可以在pc上直接测试。
2. dev_prj为DEV-C++ 5工程文件。其中包含可以在windows直接运行的melp.exe文件、pcm格式声音测试输入文件16bit.raw和解码后的输出文件2.4k.au。
3. vc6_prj为vc6工程文件。其中同样包含可以在windows直接运行的melp.exe文件、pcm格式声音测试输入文件16bit.raw和解码后的输出文件2.4k.au。
4.readme简易的操作说明
(Includes three folders with a simple documentation which 1. Pc as sentinel of the source code, non-floating point code Oh, also contains two project code, can be directly tested on the pc. 2. Dev_prj for the DEV-C++ 5 project file. Melp.exe file which contains the windows can be run directly, pcm sound test input file format 16bit.raw and decoded output file 2.4k.au. 3. Vc6_prj as vc6 project file. Which is also included in the melp.exe document windows can be run directly, pcm sound test input file format 16bit.raw and decoded output file 2.4k.au. 4.readme simple instructions)
