# AudioMixerGroup

> Object representing a group in the mixer.

## Definition

* **Type:** Class
* **Namespace:** [UnityEngine.Audio](/engine/6000.3/script-reference/unityengine/audio.md)
* **Assembly:** UnityEngine.AudioModule
* **Inherits from:** [Object](/engine/6000.3/script-reference/unityengine/object.md)

```csharp
public class AudioMixerGroup : Object
```

## Remarks

Used to route audio to specific channels in an [AudioMixer](/engine/6000.3/script-reference/unityengine/audio/audiomixer.md), allowing for grouped processing and effects.

Commonly used for managing different categories of sounds, like music, sound effects (SFX), and dialogue with shared volume controls and audio effect settings.

[AudioMixerGroup](/engine/6000.3/script-reference/unityengine/audio/audiomixergroup.md)s can be nested for more complex audio hierarchies. Typically, a root "Master" group is used that contains multiple specific groups like "Music", "SFX" and "Dialogue".

```csharp
using UnityEngine;
using UnityEngine.Audio;

// Example of a class that manages audio in a game
public class AudioManager : MonoBehaviour
{
    // References to the AudioMixer and AudioSources
    public AudioMixer audioMixer;
    public AudioSource musicSource;
    public AudioSource sfxSource;

    // Handles to the AudioMixerGroups
    private AudioMixerGroup musicGroup;
    private AudioMixerGroup sfxGroup;

    private void Start()
    {
        // Find the AudioMixerGroups and set the output of the AudioSources to them
        musicGroup = audioMixer.FindMatchingGroups("Music")[0];
        musicSource.outputAudioMixerGroup = musicGroup;

        sfxGroup = audioMixer.FindMatchingGroups("SFX")[0];
        sfxSource.outputAudioMixerGroup = sfxGroup;

        SetMusicVolume(0.8f);
        SetSFXVolume(1.0f);
    }

    public void SetMusicVolume(float volume)
    {
        // Set the volume of the Music group in the AudioMixer
        // Volume needs to be exposed in the AudioMixer
        audioMixer.SetFloat("MusicVolume", volume);
    }

    public void SetSFXVolume(float volume)
    {
        // Set the volume of the SFX group in the AudioMixer
        // Volume needs to be exposed in the AudioMixer
        audioMixer.SetFloat("SFXVolume", volume);
    }
}
```

**Note:** Create your [AudioMixerGroup](/engine/6000.3/script-reference/unityengine/audio/audiomixergroup.md)s in the editor before referencing them in code.
