# AudioSpeakerMode

> The speaker configurations that Unity supports.

## Definition

* **Type:** Enum
* **Namespace:** [UnityEngine](/engine/6000.0/script-reference/unityengine.md)
* **Assembly:** UnityEngine.AudioModule

```csharp
public enum AudioSpeakerMode
```

## Remarks

Unity supports multiple speaker types. Each speaker type has a different number of channels and is suitable for different device types and situations. The operating system (OS) and hardware determine the final output. Unity requests a mode, but the system might override it. Always check the actual mode at runtime.

**Note:** `AudioSpeakerMode` configures the global audio output layout for the entire application. It doesn't assign an [AudioSource](/engine/6000.0/script-reference/unityengine/audiosource.md) to an individual speaker channel (for example, front left or rear right). To place sounds in the mix, use [AudioSource.panStereo](/engine/6000.0/script-reference/unityengine/audiosource/panstereo.md) for left-right balance on mono or stereo clips, [AudioSource.spatialBlend](/engine/6000.0/script-reference/unityengine/audiosource/spatialblend.md) and the source position for 3D spatialization, [AudioSource.spread](/engine/6000.0/script-reference/unityengine/audiosource/spread.md) for multichannel clips in speaker space.

The following are common uses for the speaker modes:

* Stereo is the standard default for most applications.
* Use Mono for accessibility reasons.
* Use 5.1 or 7.1 for high-end PC and console setups, home televisions, theaters.
* Use Quad and 5.0 for specific installations.
* Only use Pro Logic if you must support matrix decoding.

Use [AudioSettings.GetConfiguration](/engine/6000.0/script-reference/unityengine/audiosettings/getconfiguration.md) and [AudioSettings.Reset](/engine/6000.0/script-reference/unityengine/audiosettings/reset.md) to request a speaker mode at runtime. The device might not accept or support your requested speaker mode. In that case:

* On some platforms, Unity automatically reduces the audio channel count (downmixes) to one your device supports.
* On other platforms, Unity runs the device's native channel count.

To set your project's default speaker mode, go to the [Audio Manager](/engine/6000.0/manual/unity-editor/editor-settings-reference/comp-manager-group/class-audio-manager.md): go to **Edit** > **Project Settings** > **Audio** and set **Default Speaker Mode** to your preferred speaker mode.

The following example demonstrates how to check the current speaker mode at runtime.

```csharp
using UnityEngine;

public class SpeakerModeExample : MonoBehaviour
{
    void Start()
    {
        Debug.Log("Current Speaker Mode: " + AudioSettings.GetConfiguration().speakerMode);
    }
}
```
