So first I changed the C++ function a little and made it return the available capture device names in an array using the OpenPropertyStore function. Since now the function had a different return type I also had to change the wrapper for it so it would work in js. Then I created a dropdown in html. In main.js I had to make a call to IPCRenderer instead of it being the other way around which was new since I need the renderer to replace the dropdown options after the applications loaded in. I did all this so that when I create the virtual driver I know which capture device to take input from and combine the mp3 files with since it can’t use the default device since that would be the virtual driver itself.
