A mode advanced natural sounding reverb.
This is a complex reverb module, but gives very good results. It uses a system known as a Feedback Delay Network. If you really want to know more there is information here and here (warning it is complex and uses lots of maths).
The reverb module.
Plugs;
Input L/Input R: The stereo audio input.
Size: Drop down list to select the “Room” size the options available are;
Cap, Can, Small Box, Box, Large Box, Closet, Room, Hall, Large Hall, Theatre, Stadium and Canyon.
Damp: Controls the amount of damping applied to the feedback.
Density:
Freq Band: Controls the bandwidth of the reverb feedback.
Decay: Controls how quickly the reverberations die down.
Pre Delay: Sets the time delay between the initial sound and the start of the reverberated sounds
Level: The main audio output level.
Mix: The Mix between wet and dry audio.
Early Mix: Controls the level of the early reflections, or the first sounds to be reflected (closest to the listener)

Can confirm with Davidson, but I don’t believe FOE is a FDN. FOE = Figure of Eight, i.e. as proposed by Datorro(fun history of how Lexicon tried to sue him).
That being said, in pure math terms, any reverb can be described as an FDN.
And the math of FDNs you can skip 99% of the time, you just need to start with an orthogonal matrix(there are quite a few, and easy to google). All the matrix is is gain weights of the feedback paths, i.e. level adjust modules.
