Decay Time is the duration of the reverberation ‘tail’. Decay High, Mid and Low controls the relative Decay Time of the High/Mid/Low frequencies specifically.

Crossover Freq. High/Low sets the frequency above/below which reverberation time is determined by the Decay Time High/Low setting.

High density (standard/high density reverberation engine), Early, Cluster and Reverb On/Solo controls. Graphical representation of Early, Cluster and Reverb. Room Size, Reverb Start and Gain controls.

A set of 3-band filters applied to each part of the time structure for fine tuning the reverberation characteristics.

Infinite ("deep-freezing" the reverb). Air Absorption/Roll Freq. simulates the frequency dependent air absorption. Modal Density, the frequency “smoothness” of the Verb engine. Panning, virtual source panning-direction offset. Width, panning width. Diffuseness, the directional information of the reverberation.

Early shape controls the amplitude rise or fall of early reflections, Early Min controls the time at which the early reflections start to appear, Early Max controls the time at which the early reflections cease to appear, Early Distribution controls the way early reflections are scattered in time.

Cluster Min controls the time at which the Cluster start to appear, Cluster Max controls the time at which the Cluster cease to appear, Cluster Distribution controls the way the Cluster is scattered in time.

Input/Ouput Gain (-/+ 12 dB) Input/Output VU Meter (-76/0 dB), Dry/Wet mix control for mixing in unprocessed signal with processed signal. Setup opens the Channel Routing Matrix where the I/O channels can be routed depending on the actual I/O configuration (for surround/multichannel use) setup.

A built in Input/Output routing matrix is provided allowing for setting up the Input/Output arrangement corresponding to the physical monitoring setup in the control room (for surround/multichannel use).

To enhance the workflow, the two Preset/Parameter slots, A and B, can be loaded with two different presets ie. two full set of parameters at the same time. Apart from saving each preset, a "Global Preset" containing both the A and B settings, and the postion of the "Morphing Slider", can be saved.

The Morphing Slider provide morphing between the parameter settings of slot A/B allowing for really creative and useful realtime tweaking. Enabling the Automation control button exposes the Morphing Slider to the host automation.

IRCAM Verb - Room Acoustics and Reverberation

VERB is an algorithmic room acoustics and reverberation processor. It has a modular construction, employing a recursive filtering reverb engine, reproducing and synthesizing the specific acoustical characteristics of any spatial sound environment.

Following a decade of intense research by the Acoustic and Cognitive Spaces Team at IRCAM, the IRCAM VERB introduce state of the art techniques for room acoustics simulation utilising advanced perceptive models, concealing the complexity behind the actual reverb algorithms and allowing for a flexible and intuitive experience for the user.

The IRCAM VERB provides eight input and output channels, presenting the option for reverberation processing in multi-channel and surround formats. A built in Input/Output (I/O) routing matrix provides instant flexibility when setting up the I/O in relation to the physical audio monitoring in the control room.

Signal Processing Features

Input/Output gain controls for adjusting the levels before and after processing.
Dry/Wet control for blending the original signal with the processed signal.

Preset and Parameter Handling

Preset/Parameter slots

To enhance the workflow the two Preset/Parameter slots, A and B, can be loaded with two full set of parameters at the same time. Apart from saving each preset, a "Global Preset" containing both the A and B settings, and the position of the "Morphing Slider", can be saved.

Parameter Morphing Slider with Automation

The Morphing Slider provides morphing between the parameter settings of slot A/B allowing for really creative and useful real-time tweaking. Enabling the Automation control button exposes the Morphing Slider to the host automation.
