# Reverb

***

### Overview

**Reverb** provides reverberation effects ranging from natural rooms to endless ambient spaces, adding depth and dimensionality to your sound. Flexible tonal shaping and dynamic controls help it sit in a mix, and it can also serve as a creative tool for spatial effects.

### 1. Effect Dropdown&#x20;

The **Effect Dropdown** lets you remove or swap the effect and load or save sub-presets. See[ **Shared Settings**](/evoke-manual/effects-rack/shared-settings.md) for dropdown options and detailed descriptions.

### 2. Filter Controls

These controls affect the variable-width band-pass filter applied to the reverb’s input. Use them to focus on specific frequencies, reduce low end, or produce warmer effects.

These settings can also be adjusted by switching the **Display Tabs** to reveal the draggable **Filter Display**.

**Filter Frequency.** Sets the center frequency of the band-pass filter where the reverb is most pronounced.

**Filter Width.** Adjusts the bandwidth around the center. Narrow settings isolate the reverb to a small band; wider settings let more of the original signal through, producing a wider frequency response.

### 3. Reverb Display&#x20;

The **Reverb Display** visualizes reverb size and decay in real time as you adjust parameters.

Switch the **Display Tabs** to reveal the **Filter Display**, which provides a draggable filter response for adjusting the reverb’s filter settings.

### 4. Reverb Controls

**Size.** Controls the perceived size of the virtual space’s early reflections. Smaller values simulate intimate rooms; larger values simulate large halls and provide material for ambient textures.

**Decay.** Determines how long the reverb tail lasts. Short decays are tight and subtle. Long decays create lush, evolving spaces.

**Modulation.** Applies subtle movement to the reverb reflections, adding richness and depth. Useful for creating dreamy or slightly detuned effects.

### 5. Ducking Controls&#x20;

The Reverb’s built-in ducking lowers the delayed signal when the input is present, preventing the input from being masked by the effect and reducing clutter within the mix.

**Depth.** Adjusts how much ducking is applied to the reverb signal. 0% results in no ducking.

**Time.** Sets how quickly ducking engages after the input plays. Short times produce immediate reductions; longer times yield smoother, more gradual transitions.

### 6. Mix Controls&#x20;

**In.** Sets the level of the wet signal path before processing. Use it as a reverb send control.

**Out.** Sets the final level after processing and dry/wet mixing.

**Mix.** Blends the unprocessed (dry) and processed (wet) signals.
