The genuine audiodg.exe file is a software component of Microsoft Windows Operating System by Microsoft Corporation.
Microsoft introduced “audiodg.exe” in Windows Vista and Server 2008 as a new process, part of new user-mode audio architecture replacing that in XP and Server 2003. Called “Audio Device Graph Isolation,” it is a core system component residing in “C:\Windows\System32” and should not be removed. It is a protected process, also a concept introduced in Vista. It hosts the audio engine separately from the Windows audio service hosted by “svchost.exe”. The audio engine performs all digital signal processing (DSP), which may include loading third-party code: Audio Processing Objects (APOs), customized DSP’s provided by audio system vendors. Only Microsoft code is allowed in anything hosted by “svchost.exe”, so executing in “audiodg.exe” in user mode isolates the audio engine. Its protected process status is required for use of Digital Rights Management (DRM) for media industry protected intellectual property including Blu-Ray and HD-DVD, which also has to be isolated from “svchost.exe”.
