Libelula Audio Ultiverb – IRZU INSTITUTE

Ultiverb is a FREE FOREVER algorithmic reverb by Libelula Audio, designed to combine flexible spatial processing with stereo movement and analog-inspired character.

It includes five reverb algorithms: Room, Hall, Plate, Spring and Digital, with controls for size, decay, pre-delay, density and early reflections. Its Fluctuate system introduces evolving differences between the left and right channels, while Speed and Inertia control the behaviour and movement of the stereo image.

Ultiverb also features multiband decay, Memory and Bloom controls, independent Dry and Wet saturation, modulation, and two four-band EQ stages dedicated to the wet signal. Five saturation characters, Clean, Soft, Tape, Tube and Clip, can be applied independently to the direct sound and reverb tail, with up to 16x oversampling available for the character stages.

4 different flavors that makes the reverb behave different: Clean, Odonata, Anisoptera and Meganeura.

Built-in ducking includes Attack, Release, Ratio and detector gain controls, with HP/LP detector filtering and support for both internal and external sidechain signals.
