Illusion Late Reverb

Introducing Fusion-IR | Synthesis

Introducing Fusion-IR | Synthesis, a groundbreaking evolution of the industry leading Fusion-IR modulated convolution technology.

Illusion goes beyond the abilities of traditional algorithmic reverbs by using a totally new approach to reverb simulation.

A suite of highly advanced reverberation technologies that are impossible to implement with any other system represents nothing less than a revolution in contemporary reverb design bringing lush, rich and evolving rooms, spaces, plates and outdoor environments to life.

Crystal Clear Modulated Reflections

A Clear Reflection of Quality

Illusion’s early reflections are synthesised using a highly advanced technique far removed from the usual diffused point-delay approach. Its modulated reflections have superb clarity and realism, absent of any undesirable colouration, phasing, flanging or chorusing artefacts.

The proximity of the receiver to the source can be freely chosen, and the reflectivity/absorption of the room can be easily controlled. A selection of different reflection patterns is helps the producer quickly audition different acoustic properties to quickly find what best fits the source.

Natural Modulation

Illusion blends a multitude of motion effects into a single modulation control – flux. At low settings the subtle beauty of a fully modulated decorrelated reverb blends organically with any instrument or vocal. Push a little higher for more noticeable spatial modulations or take it right up to the max for an enriching fully chorused reverb. Or switch off the flux for the purity of a completely still reverb. It is simplicity itself; the choice is all yours.

Illusion Late Reverb Decay

Rich Reverberant Tails

Whether you need a reverb that is sparse and reflective to enhance the clarity and space of a delicate vocal performance or a lush, rich and warm space befitting an orchestral ensemble, Illusion synthesises beautiful still or modulated decays to suit any musical genre.

With a high level of clarity and realism Illusion’s collection of highly advanced reverb generation techniques excel in the simulation of almost any reverberant environment. Illusion provides powerful and intuitive control over a space’s perceived size, reflectivity, low-end response and multi-band decay rate.

Illusion’s advanced algorithms are designed to simulate:

  • Small environments – for tight, dense chambers and rooms
  • Large environments – for more spacious spaces such as churches, cathedrals and halls
  • Classic plates – reproducing the unique dispersive and multi-band decay properties of classic metallic plate reverbs
  • Nonlinear reverbs – famous for classic 80s percussion (available as part of the early reflections processor for combination with any of the above)


Compress & Duck Reflections, VLF, Reverb or Wet Signals

Ducking the reverb can often increase clarity of a performance during a vocal phrase because there is less competition in the mix for the vocal, but then when the singer takes a pause the reverb level can quickly recover allowing the reverb to move in to fill the space. Intelligibility is improved greatly with little effort from the producer.

The trouble with just running a compressor (with side-chain for ducking) over an entire reverb as a mixer insert effect is that it drags down the early reflections as well, but these are crucial for effective spatialisation.

With Illusion’s dynamics processors you can selectively compress or duck the reverb signal and leave the reflections at full volume. You will get all the benefits of the reflections and increased tail clarity during vocal phrases or busy instrumentation by pushing down the late reverb until the mix has the space for it to shine.

"The dynamics section is the secret weapon here. I can shape and fine-tune the way the reverb works in the track with a couple of clicks, in ways that used to involve a long chain of plugins."

Illusion Reverb Controls

Precise Imaging Control


Illusion provides up to three tempo-synchronised reflections so you can design complex, realistic spaces with multi-faceted areas.


With full control over early and late tempo-synchronised early and late reflections, Illusion has powerful abilities to sit the reverb with any source material.

The low frequency reverb pre-delay can even be linked to early or late processors.


An innovative true-stereo width control can take your reverb from mono through to an optimally wide fully decorrelated true stereo image without any phase or mono-compatibility artefacts.

"Beautiful stereo imaging and very good CPU performance, couldn’t ask much more for a professional reverb."

Alan Branch, Grammy Award Winning Mixer

Powerful Equalisation

Analogue Early and Late Roll-off Filtering

The early reflection and late reverb modules can both be tuned with analogue style filters ranging from 6 to 36 dB/Oct roll-offs. This level of flexibility is important as many early reverb designs tended to use very shallow 6 or 12 dB/Oct filters when processing capabilities were more limited, whereas some newer reverbs have a steeper roll-off.

Digital Brick-Wall Filtering

Classic digital reverbs of the 1970s and 1980s often had very limited audio bandwidth due to low processing sample rates. This adds a very characteristic sound to a reverb and can be reproduced in Illusion for a hit of nostalgia.

Versatile Reflection, Reverb and Master Parametric Filtering

For each of the early and late modules a 5-band over-sampled EQ is provided, and a further 5-band master EQ is provided for control over the overall reverb tone. A spectrum analyser is included to illustrate the spectral content of each component.

"The amount of control is amazing without being overwhelming. The GUI is clear and the dynamics and ducking sections are amazing, the ability to apply ducking to different components of the effect is great."

Nuno Fernandes (Bryan Adams, Diana Krall)

Audio Examples

Each sample starts off untreated, the reverb is faded in and then back out of the audio example to help the listener get a sense of the reverb at different mix settings.
