Class Methods

GVerb.ar(in, roomsize: 10, revtime: 3, damping: 0.5, inputbw: 0.5, spread: 15, drylevel: 1, earlyreflevel: 0.7, taillevel: 0.5, maxroomsize: 300, mul: 1, add: 0)

Arguments:

in

mono input.

roomsize

in squared meters.

revtime

in seconds.

damping

0 to 1, high frequency rolloff, 0 damps the reverb signal completely, 1 not at all.

inputbw

0 to 1, same as damping control, but on the input signal.

spread

a control on the stereo spread and diffusion of the reverb signal.

drylevel

amount of dry signal.

earlyreflevel

amount of early reflection level.

taillevel

amount of tail level.

maxroomsize

to set the size of the delay lines. Defaults to roomsize + 1.
