## What is Kleverb?

Kleverb is a high quality algorithmic reverb effect. An intuitive UI combined with a carefully calibrated network of filters and delays makes this a powerful effect useful in any context; all from acoustic jazz to EDM.

With three different room size setups (SMALL, MEDIUM, LARGE), selectable filter on both early and late reflections, modulation, damping, diffusion and much more (see below) almost any kind of room can be simulated.

There’s also a ducker included that uses the dry signal as sidechain. Very useful to keep vocals or other solo instruments distinct even when they’re soaking wet.

The 64 factory presets covers most of the Kleverb features.

Features:

• Room size selection.
• Filters with selectable type on both early and late reflections.
• Wet signal modulation.
• Damping filter.
• Diffusion and Stereo Spread parameters.
• Decay time between 0 and 25 seconds.
• Pre delay parameter.
• Ducker (compressor), with dry signal as sidechain.
• Early / Late signal mix parameter.
• Wet and Dry signal level parameters.

Full documentation available inside the app or at https://klevgrand.se/download/kleverb-docs/

Kleverb works both as a standalone app and as an AUv3 plugin.

### 5/5 — Always Kleverb

*2026-02-27, version 1.1.1*

I have lots of reverb, but I always use Kleverb… except when I’m using Walls.

### 4/5 — I AdMiRe tHe KLeVGR STeeZ!?!

*2019-10-25, version 1.0.0*

I wish I could I save my own presets within the AuV3 to recall them later. 

Other than that, 
of course I love their
unique one of a kind 
Reverb audio unit...

                        ... Honestly, it’s hard to dislike anything by the developer(s)

### 3/5 — Bugs,

*2019-02-27, version 1.0.0*

Love the app but can you fix the distortion on iPad Air 2 128 gbs? It happens when I try to load more than 1 auv3

### 5/5 — Great reverb

*2018-12-27, version 1.0.0*

Another fantastic offering from these amazing developers 
Thank you!

### 5/5 — Simply Excellent

*2018-12-14, version 1.0.0*

This is a beautiful sounding reverb!. Well worth it!!

### 5/5 — Sounds fantastic and super intuitive.

*2018-11-13, version 1.0.0*

I love how intuitive this is and it does not sacrifice quality.  

Having the iOS and desktop version is great for workflow.  Cannot overstate this.

### 5/5 — The new king of ios reverb

*2018-11-03*

the features, the sound, the smart UI. Like the name this is a very clever reverb plugin.  the compressor, ducker, filters etc make this the only reverb I need.  it doesnt sound metallic and clangorous like other auv3 verbs, it doesnt wet the sound to the point of being inaudible while still delivering large cavernous space.  Absolutely exceptional and I don't see it losing it’s crown anytime soon.

### 5/5 — Great

*2018-11-02, version 1.0.0*

Great interface and something new and professional level here
