I use a free VST plug-in for stereo expanding (works wonders when working with a mono file) and I recently had to reinstall Windows. Now I can't for the life of me recall the name of the Plug-in. I know this is VERY vague and requires some "Jedi Mind Reading" tricks to read my mind, but I have used this plug-in with great success and I hate to not have it in my arsenal of plug-ins.
While on the subject, is there any plug-ins (preferably the free kind) that you find yourself using a lot and if so, what is it and what does it do?
Thanks for the help and sorry for the terrible description of what I am looking for
