I'm looking for methods in Linux to add reverberation to sounds (not necessarily in real time) using controls based on room size and specifications. I've found some LADSPA plugins that have simple controls - - GVerb, Freeverb, and Stereo reverb - which would work if I can't find anything else. Does anyone know of any options of any sort that provide more complex controls (room dimensions in three directions, damping, placement of source and mic)? Thanks for any advice.
