代码说明：

  This module implements the interface and output system for Windows Media Audio. If you use this module with your application, you will need to deploy wmaudioredist.exe (the CORE) with your program. The SDK (and the CORE) are claimed by Microsoft to be BETA. It seems to work correctly, but beware of BETA! Please, notify me, when Microsoft releases the final version of the SDK. Redistribution terms for this module consist of two parts. 1) wmamp.esp redistribution terms are defined by EldoS Sounds license. 2) The CORE redistribution terms are defined by Microsoft. As for now its redistribution is free.
