LiquidSonics’ Illusion is a revolutionary new reverb 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 with a suite of highly advanced reverberation technologies that are impossible to implement with any other system. It represents nothing less than a revolution in contemporary reverb design.

From simulations of natural environments including beautiful halls, chambers and rooms to classic nonlinear and plate reverbs, Illusion synthesises an incredibly diverse range of spaces that blend seamlessly with drums, guitars, synthesisers, vocal performances and orchestral ensembles.


Illusion comes with over 200 professionally designed presets so quickly placing your drums, guitars, vocals or strings in a convincing space is a breeze. Or if you prefer to really get into the details, designing the perfect reverb for your track is quick and easy using a powerful collection of intuitive controls.

Illusion pioneers a breakthrough approach to reverb simulation known as Fusion-IR | Synthesis.

A suite of highly advanced reverberation technologies synthesise Fusion-IRs to your precise specifications without the use of an external library of sampled impulse responses. Its beauty truly comes from within and it is perhaps the most versatile reverb processor available today.

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)

A reverb’s early reflections provide the aural cues that define how we initially interpret the size, shape and composition of reverberant environments. These are typically simulated with a small number of basic delays spaced a few milliseconds apart in series with a diffuser or very short reverb to thicken the sound. Closely spaced delays often cause phasing or undesirably heavy colouration considerably degrading reverb 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.

Illusion’s reflection synthesis engine can even be used to create non-linear reverb patterns offering a rich, modern twist on the classic nonlinear reverb sound of the 80s.

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 Linear Phase 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.

Many classic reverbs required modulation to hide the undesirable artefacts often associated with low-complexity delay-loop feedback reverb designs. Whilst technically quite unnatural, musically this modulation was often very pleasant creating unique rich chorusing and liveliness. From a subtle spin and wander to more extreme chorusing, producers started to find these sonic signatures highly desirable.

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.

The flux of the early reflections and late reverb can be controlled individually, so some wild chorusing in the tail does not need to diminish the purity of early reflections. Or an initial hit of modulation in an early reflection pattern does not need to bleed into a reverb tail.
