Windows Audio Device Graph Isolation is an audio file for recent versions of Windows that prevents other applications from modifying audio-related content and plug-ins. The application also serves as the audio engine for Windows.

Sound isolation is great for blocking speech, a noisy television, music â it works in all kinds of environments whether youâre sitting on a plane, a train or walking down the street.
