# PHASEMaterialPreset

A collection of physical surfaces that each add a unique acoustic quality to your app’s audio.

```
enum PHASEMaterialPreset
```

## Overview

This enumeration defines the types of surface texture that you choose for your scene’s objects. To assign a preset to a material, define the `preset` argument for the material’s [`init(engine:preset:)`](/documentation/PHASE/PHASEMaterial/init(engine:preset:)) initializer.

## Topics

### Presets

[`case brick`](/documentation/PHASE/PHASEMaterialPreset/brick)

A surface characteristic that produces the acoustic quality of brick.

[`case cardboard`](/documentation/PHASE/PHASEMaterialPreset/cardboard)

A surface characteristic that produces the acoustic quality of cardboard.

[`case concrete`](/documentation/PHASE/PHASEMaterialPreset/concrete)

A surface characteristic that produces the acoustic quality of concrete.

[`case drywall`](/documentation/PHASE/PHASEMaterialPreset/drywall)

A surface characteristic that produces the acoustic quality of drywall.

[`case glass`](/documentation/PHASE/PHASEMaterialPreset/glass)
