本代码实现了将MP3文件转换为wav格式音频文件。在上位机上已经成功跑起来了，希望有人能把它移植到嵌入式ARM中。-The source implementation of the MP3 file converted to wav format audio files. Has been successfully up and running on the host computer, and hope someone can port it to embedded ARM.

在arm系统中，经常用到的小型MP3算法，该算法速度相当快，代码效率很高，而且提供了定点版本，对应用于arm系统是不二的选择-In the arm system, a small MP3 algorithm is often used, the speed of the algorithm is quite fast, code with high efficiency, but also provides a fixed-point version, the application in th
