Name
Reverb -- add reverberation
Synopsis
reverb [-w|--wet-only] [reverberance (50%) [HF-damping (50%)
       [room-scale (100%) [stereo-depth (100%)
       [pre-delay (0ms) [wet-gain (0dB)]]]]]]
Function
Add reverberation to the audio using the "freeverb" algorithm. A reverberation effect is sometimes desirable for concert halls that are too small or contain so many people that the hall's natural reverberance is diminished. Applying a small amount of stereo reverb to a (dry) mono signal will usually make it sound more natural.

Note that this effect increases both the volume and the length of the audio, so to prevent clipping in these domains, a typical invocation might be:

 
gain -3 pad 0 3 reverb

The -w option can be given to select only the "wet" signal, thus allowing it to be processed further, independently of the "dry" signal.
