Would this result in some kind of reverb type effect as Fons suggested? I'm looking for a way to adjust the phase of a signal rather than the amplitude. Does such a plugin already exist? If not which ladspa plugin would be the most suitable to start from? I've looked at using parts of jamin and librubberband but there may be a faster to implement option available.
