Okay, so I was trying out the free trial for the AV Voice Changer DIAMOND 7.0. I didn't like it too much so I uninstalled it. After uninstalling it, parts of it were still left. I think may have been that the drivers were not uninstalled, because there were still things related to the program in the Playback and Recording tabs in Control Panel > Sound.

Here are some screenshots:



Seeing as these still remain, how do I completely uninstall this program?

I'm sorry I wasn't satisfied with the program, because I wanted to try out the 14-day trial, but I couldn't "try" it because it was severely limited.
