 # voicemeeter-auto-affinity

+Automatically sets the affinity of "audiodg.exe" to only one core on computer start to fix the crackling noises that can
+occur in VoiceMeeter.
+
+## The Problem
+Some users of the program VoiceMeeter have a problem with a sound channel having crackling noises. This can be fixed by
+setting the affinity of the windows process "audiodg.exe" to only one core. This, however can not be done persistently
+in Windows itself, so a common solution is to use [Process Lasso](https://bitsum.com/). My problem with this solution was
+that the free version of this program asks to buy the paid version on every boot and constantly runs in the background although
+the only feature I use does not require that. This is why I decided to write a simple batch script that is run once on
+system boot and changes the affinity of audiodg to only one core.
+
+## How to Use
+To install the batch script, do one of the following:
+
+### Using the Installation Tool
+To conveniently install the batch script, download the InstallationTool.exe from the
+[releases page](https://github.com/Gobidev/voicemeeter-auto-affinity/releases) and click the Install button.
+
+### Manual Installation
+Download the batch file directly and place it into the startup folder that you can access by pressing WIN + R and typing
+"shell:startup".
