# Reverb

The reverberation RealityKit applies to spatial audio sources.

```
struct Reverb
```

## Overview

You can configure the reverb for spatial audio sources in your RealityKit content with the [`ReverbComponent`](/documentation/RealityKit/ReverbComponent).

```swift
let cinema = Entity()
let reverb: Reverb = .preset(.mediumRoomDry)
cinema.components.set(ReverbComponent(reverb: reverb))
```

## Topics

### Creating a reverb

[`static func simulated(mesh: ReverbMeshResource, materials: [Audio.Material]) -> Reverb`](/documentation/RealityKit/Reverb/simulated(mesh:materials:))

A reverb that is simulated from a reverb mesh and materials.

### Structures

[`struct Preset`](/documentation/RealityKit/Reverb/Preset)

Reverbs defined by a preset environment.

### Type Properties

[`static let anechoic: Reverb`](/documentation/RealityKit/Reverb/anechoic)

A reverb instance that applies no reverberation to spatial audio sources.

### Type Methods

[`static func preset(Reverb.Preset) -> Reverb`](/documentation/RealityKit/Reverb/preset(_:))

Returns a reverb instance that you can set on a reverb component.
