Description: mad mp3解码dll
libmad is a powerful open source library written in C that decodes MP3 files to uncompressed PCM data. However, it compiles as a static library, limiting its access to C/C++. I have written code (based on the source madlld) that compiles to a DLL, enabling other languages (i.e., C#, Visual Basic etc.) to access the libmad library using the simple interface I ve provided.
