# Filter Tuning Panel

The Filter Tuning Panel balances expression response and motion stability.

### Primary operator controls

* **Mouth Response** increases mouth speed at higher values.
* **Mouth Stability** increases deadband at higher values.
* **Jaw Response** increases jaw landmark speed at higher values.

### Built-in smoothing

Control NVIDIA SDK temporal smoothing for **Face Position**, **Face Landmarks**, **Head Motion**, **Facial Expressions**, and **Eye Gaze**.

Disabling **Facial Expressions** smoothing gives the fastest mouth response. Check stability before capture.

### Advanced filters and resets

Advanced App Filters include OneEuro, Butterworth, predictive interpolation, landmark smoothing, distance adaptation, jaw and mouth compensation, and LiveLink tuning.

Use **Bypass App Filters (Raw)** to compare raw and filtered output.

Use **Flush Filter State** to clear temporal history without changing parameters.

Use the slot and filter reset controls to restore known defaults.
