object GVerb extends Serializable

A stereophonic reverb UGen. It is based on the GVerb LADSPA effect by Juhana Sadeharju.

Note: A CPU spike may occur when the synth is instantiated. Warning: The UGen has a bug which results in loud noise if the room size is increased during playback. It seems safe to start with a large room size and decrease the value during playing. Warning: The UGen may crash the server if roomSize becomes larger than maxRoomSize .

Examples
// mouse control for time and damping
play {
  val tr   = Impulse.ar(1)
  val in   = Decay.ar(tr, 0.25) * LFCub.ar(1200) * 0.1
  val damp = MouseX.kr
  val tail = MouseY.kr(1, 100, 1)
  GVerb.ar(in, roomSize = 20, revTime = tail, damping = damp, maxRoomSize = 20)
}

    roomSize

    Size of the virtual room in meters. It must not be greater than maxRoomSize . Note that quick changes in roomSize may result in zipper noise and an audible Doppler effect.

    revTime

    reverberation time in seconds.

    damping

    high frequency attenuation (1 is maximum attenuation)

    inputBW

    high frequency attenuation of the input signal (0 to 1)

    spread

    stereo spread of the reverb signal. Units?

    dryLevel

    amount of dry signal

    earlyRefLevel

    amount of early reflections

    tailLevel

    amount of late reverberation

    maxRoomSize

    maximum value that roomSize can take. This is used for the early reflection delay lines and is only read at initialization time. (init-time only)
