What is Audiodg exe? 5 ways to fix high CPU usage

Windows is powered by hundreds of background processes behind the scenes, and seeing some of those processes eat up all your resources isn’t a new thing.

While the high resource usage generally happens in spikes, continued usage can cause you unwanted troubles. In this article, we’re talking about the audiodg.exe process and ways to stop it from consuming all your CPU.


What is the audiodg.exe process?

As you can probably guess, audiodg or Windows Audio Device Graph Isolation process is responsible for the operating system’s audio engine. The file is used for any audio processing and Digital Signal Processing (DSP). 

Third-party vendors can also install their own DSP and audio effects in the pipeline, which are processed by the audiodg file.

How to fix audiodg’s high CPU usage?

As mentioned above, audiodg might temporarily use up a lot of your CPU, but if the behaviour is sustained, it can cause problems. Here are a few steps you can take to prevent this from happening.

Update the game or concerned program

If the issue only arises when you’re playing a certain game or using a particular program, the issue might be in the game or program and not with audiodg. In such cases, chances are the developer has identified the issue and has released a patch. Try and update the game or program and try again. 


Change the audio sample rate

Changing the audio sample rate can help bring down the process’ workload and reduce CPU usage.
