# maxDistance

> The distance where sound either becomes inaudible or stops attenuation, depending on the rolloff mode.

## Definition

* **Type:** Property
* **Namespace:** [UnityEngine](/engine/6000.7/script-reference/unityengine.md)
* **Assembly:** UnityEngine.AudioModule

```csharp
public float maxDistance { get; set; }
```

### Remarks

[AudioRolloffMode.Linear](/engine/6000.7/script-reference/unityengine/audiorolloffmode/linear.md): For the linear rolloff mode, the `maxDistance` is the point where the volume reaches zero and the sound becomes inaudible.

[AudioRolloffMode.Custom](/engine/6000.7/script-reference/unityengine/audiorolloffmode/custom.md): For the custom rolloff mode, the `maxDistance` sets the distance bounds of the curve. Any distance beyond holds the last available value.

[AudioRolloffMode.Logarithmic](/engine/6000.7/script-reference/unityengine/audiorolloffmode/logarithmic.md): For the logarithmic rolloff mode, the audio source ignores this setting. The sound will continue to attenuate with distance indefinitely.
