# rotationRateUnbiased

> Returns unbiased rotation rate as measured by the device's gyroscope.

## Definition

* **Type:** Property
* **Namespace:** [UnityEngine](/engine/6000.3/script-reference/unityengine.md)
* **Assembly:** UnityEngine.InputLegacyModule

```csharp
public Vector3 rotationRateUnbiased { get; }
```

### Remarks

The rotation rate is given as a Vector3 representing the speed of rotation around each of the three axes in radians per second. This value has been processed to remove "bias" and give a more accurate measurement. The raw value reported by the gyroscope hardware can be obtained with the [Gyroscope.rotationRate](/engine/6000.3/script-reference/unityengine/gyroscope/rotationrate.md) property.

### Examples

```csharp
using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour
{
    public float shakeSpeed;
    public AudioClip shakeSound;
    AudioSource audioSource;

    void Start()
    {
        audioSource = GetComponent<AudioSource>();
    }

    void Update()
    {
        if (Input.gyro.rotationRateUnbiased.y > shakeSpeed && !audioSource.isPlaying)
            audioSource.PlayOneShot(shakeSound);
    }
}
```
