# Troubleshoot audio misconfiguration: Noise Cancellation

## **Introduction**

Before you begin, make sure:

- The Sanas app is installed, launched, and activated.
- A high-quality (USB type) headset is connected to your computer.
- You have administrative access on your computer (some changes may require an admin password).
