Deverb. I am certain that I did it by loading a negative room size into a very old version of GVerb. Don’t have or recall the version. It took echo out of a back of the room recording and gave the performer more presence. Anyone know how I can get to old versions of GVerb to prove that the functionality (although probably unintended) existed?
I’m sure you’re mistaken. Old LADSPA versions (2001) for Linux are available from here http://plugin.org.uk/releases/0.2.0/
