what the author say :
Ambia uses a 3D room model to create early reflections for positioning the sound source, and has an experimental reverberator for diffusion to add some ambiance. The plugin is still an early beta.

he also has 2 others ones ( love the wind chimes models)
WindChimes beta 0.5c WindChimes models wind forces and a wind chime with a selectable number of bars. It issues MIDI notes when a chime is struck.
and GrainMaker is a granular VST effect
