Klevgrand Revolv

Austrian Audio Hi-X20

Klevgrand’s Revolv is an IR‑based reverb plug‑in that supports all the usual macOS/Windows formats including AAX, and offers a wide range of spaces with very different characters. It’s all wrapped in an interface that allows for quick auditioning of the different reverbs, and the ability to dive in deeper and adjust parameters such as mic type, mic distance and EQ if required. The IRs were recorded by sound designer Oscar Björk at various locations across Sweden, in a range of hand‑picked locations.

The GUI is certainly different from the norm. It’s set out as a wheel with 12 segments, each hosting an image of a reverberant space. A magnifying glass can be placed over any image to load that impulse, while a slowly moving pan shot of the selected space is shown inside the magnifying glass. A gimmick maybe, but it’s a very attractive one! The large knob in the centre sets the wet/dry mix, and for many applications that may be all you need. As you move the mouse pointer over an image, the name of the space is displayed above and to the right of the wheel.

Click on the three faint horizontal lines at the top right of the GUI and you’ll find six different categories: Ruins and Nature, Historic Halls, Old and Etherial, Modern Gatherings, Wooden Rooms, and Stages. Choose one and the wheel will present you with 12 spaces from that category. Here you’ll find spaces as diverse as kitchens, caves, cathedrals, concert halls, parking garages, crypts, towers and stone ruins, plus some natural outdoor spaces. There’s even a plane cockpit. There’s also an 11‑category preset browser, with many presets offering alternative mic setups for each space.

If you want to edit at a deeper level, double‑clicking the magnifying glass brings up a window in which you can adjust the pre‑delay and decay times, the wet/dry mix, gain, EQ, width and mic type and, where applicable, mic placement. You’ll also find a brief description of the space here.

If you want to put your voice or instrument into a specific real space with a very strong sense of character, then Revolv provides lots of useful options.

Clearly, Revolv might not be the first reverb of choice if you simply need a plate‑style decay with no obvious character, but if you want to put your voice or instrument into a specific real space with a very strong sense of character, then Revolv provides lots of useful options. While it doesn’t work much differently from other IR‑based reverbs, the selected locations each have a unique character and the unorthodox GUI makes it quick and very easy to find a space that works. Interestingly, adding the character of some of the outdoor spaces can seem to make the sound drier than before adding the reverb, while the stone buildings add a real sense of the character of the space. If you want a reverb that tells a story, then Revolv is both approachable and affordable.
