# SpatialAudioExperiences.SoundStageSize

Configure the distribution of audio channels in 3D space.

```
enum SoundStageSize
```

## Overview

For multi-channel sounds, the sound stage size describes how the channels
are positioned relative to the coordinates described in the sound’s channel
layout.

## Topics

### Enumeration Cases

[`case automatic`](/documentation/AudioToolbox/SpatialAudioExperiences/SoundStageSize/automatic)

A system-defined sound stage size.

[`case large`](/documentation/AudioToolbox/SpatialAudioExperiences/SoundStageSize/large)

Spreads an audio stream’s channels around the user according to the
coordinates described in its channel layout.

[`case medium`](/documentation/AudioToolbox/SpatialAudioExperiences/SoundStageSize/medium)

Pulls an audio stream’s channels closer to the channel layout’s front.

[`case small`](/documentation/AudioToolbox/SpatialAudioExperiences/SoundStageSize/small)

Places all of an audio stream’s channels near the layout’s front.
