Introduction

This script is designed to optimize the performance of Audiodg.exe and Voicemeeter8x64.exe by setting their process priority to High and limiting them to a single CPU core. This can help improve audio processing performance on Windows systems.

Installation

1. Download the .bat file from the Releases page.
2. Press Win + R, type shell:startup, and press Enter.
3. Copy the downloaded .bat file into the Startup folder that opens.

Usage

1. On the first run, the .bat file automatically downloads the corresponding PowerShell script.
2. If you run the script via Autostart, you must accept the PowerShell permission prompt (UAC) to allow it to run with the required privileges.
3. The .bat file is set up to handle Voicemeeter. If you only need to adjust Audiodg, please use the .ps1 script for Audiodg directly.

Important Notes

• You only need to download the .bat file!
• Changing the priority or affinity of Audiodg.exe may be blocked on some versions of Windows because it runs as a "Protected Process Light". In that case, "Access denied" is possible even for an administrator.

Troubleshooting

If PowerShell Denies Permission

1. Change your PowerShell Execution Policy to either RemoteSigned or Unrestricted:

   Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Force

   or

   Set-ExecutionPolicy -ExecutionPolicy Unrestricted -Force

2. Try running the script again. It should now work as intended.
