What it does

Kleverb is Klevgrand's "Algorithmic Reverb", described as "A smart reverb, designed to fit in any mix." It simulates rooms of different sizes on one page and adds a built-in ducker, so the tail stays clear of the dry signal; Klevgrand pitches it for anything from acoustic jazz to EDM.

Room sizes: three room types to choose from: small, medium and large.
Decay and pre-delay: decay from 0 to 25 seconds, plus a pre-delay control.
Filters: selectable filter types on the early reflections and on the late reflections, plus a separate damping filter for the tail.
Character: modulation of the wet signal, a diffusion control and a stereo spread control.
Early/late mix: set the balance between early reflections and the late tail.
Ducker: a compressor on the reverb that uses the dry signal as its sidechain, so the tail dips while the source plays.
Levels and presets: separate wet and dry level controls, and 64 factory presets.

The current version is 1.1.3. The free demo is the full version with occasional audio dropouts.

When to use it

Kleverb is the simpler, lighter choice when you want a clean mix reverb with ducking built in. Compared with FabFilter Pro-R 2 it has no visual decay EQ or detailed tail display, but it covers the basics (size, decay, filters, modulation) and adds a ducker that Pro-R 2 does not have. It is less coloured than VintageVerb, with no era or vintage modes, and offers fewer room algorithms than Valhalla Room. Users on iPad also found it light on CPU, which helps when running several instances.

Best for: everyday reverb on vocals and instruments where the tail must not cloud the dry part, and lightweight reverb on iPad setups.
Genres: all genres, from acoustic and jazz to pop and EDM.
Look elsewhere if: you want vintage hardware colour (VintageVerb), detailed visual control (Pro-R 2) or huge creative spaces (Supermassive or Blackhole).
Tip: with separate wet and dry levels it works on an insert as well as a send, as users in the Loopy Pro thread pointed out.

What producers say

The few user comments found are positive about the sound and the low CPU load, mainly from iPad users of the AUv3 version.

Loopy Pro (Audiobus) forum users praised the sound and the GUI, called it lightweight, and one expected it to become their "go to reverb".
Comparisons: one user contrasted it with RF-1, which they found more "demanding cpu wise".
Usage note: the thread discussed using it on inserts as well as sends, which its independent wet and dry controls allow.
