From the program Microsoft WINMM WDM Audio Compatibility Driver, which is created by Microsoft Corporation, the wdmaud.sys process is a driver file that is referred to as the MMSYSTEM Wave/Midi API mapper. MMSYSTEM Wave/Midi API mapper, which is launched by the file wdmaud.sys, is an important component of the WINMM WDM Audio Compatibility Driver software, because its primary task is to install all the core components of the driver software.

Once the software is executed, this file also functions and enables all core parts to launch, which generally make the WINMM WDM Audio Compatibility Driver work. Moreover, WINMM WDM Audio Compatibility Driver is designed to give support for the kernel mode processing of real time audio stream. In other words, this application is a part of the Kernel Audio Support macro component.
