fx:reverb implements a high-quality reverb algorithm. Reverb or reverberation is the effect of resounding echos in a room or other enclosed acoustic environment. fx:reverb emulates the phenomenon of sound being reflected off walls in a virtual room, and allows you to add reverb that resembles the character, decay and frequency response of various environments.

Among the many features of fx:reverb is high- and low-frequency cutoff for filtering the input signal, parameters for controlling the room size, echo diffusion, decay time, high-frequency damping, early reflections and more. Many of the parameters can be edited visually through intuitive graphic representations. The width of the stereo image can be freely adjusted, from mono to ultra-wide stereo. Input, output and reverb levels can be adjusted individually or muted for fast previewing. fx:reverb offers all the features that a good reverb should, and then some.
