Yes, Stereo Tool can add 10% or more to the WACUP CPU load depending on the CPU being used. I should have included this fact in my first post about this DSP plug-in. I can accept this load given all that Stereo Tool can do and I still have plenty of CPU resources left on my system to run other apps when I'm using WACUP. Computer resources are there to be used and as long as I can run what I want, I don't really care if a lot of the resources are used from time to time.
There are also configuration options that can to used to reduce the CPU load. In addition, once Stereo Tool is configured the way you want (which can take some time to figure out) it can be ran in invisible mode which eliminates any load on the GPU.
