summary:: A two-channel reverb
categories:: UGens>Reverbs
related:: Classes/FreeVerb, Classes/FreeVerb2
description::
A two-channel reverb link::Classes/UGen::, based on the "GVerb" LADSPA effect by Juhana Sadeharju (kouhia at nic.funet.fi).
subsection:: Known issues
list::
## There is a large CPU spike when the synth is instantiated while all the delay lines are zeroed out.
## Quick changes in roomsize result in zipper noise.
## emphasis::Changing the roomsize does not work properly! Still trying to look for the bug... (-josh)::

classmethods::
method:: ar
argument:: in
mono input.
argument:: roomsize
in squared meters.
argument:: revtime
in seconds.
argument:: damping
0 to 1, high frequency rolloff, 0 damps the reverb signal completely, 1 not at all.
argument:: inputbw
0 to 1, same as damping control, but on the input signal.
argument:: spread
a control on the stereo spread and diffusion of the reverb signal.
argument:: drylevel
amount of dry signal.
argument:: earlyreflevel
amount of early reflection level.
argument:: taillevel
amount of tail level.
argument:: maxroomsize
to set the size of the delay lines. Defaults to roomsize + 1.
argument:: mul
argument:: add
