Searching for plugin I cannot remember!! Something like Plugindoctor as a VST!

[Trancit]

As the title says...

I had a free plugin which you could insert as a plugin in front and after a processing chain to measure frequency and phase response...

I cannot remember how it was called!!

Help!!! Please!!!
