Introduction

This guide walks you through setting up and using the Sanas desktop app with Noise cancellation (NC).

New to Sanas? Take a short tour of the Sanas app to learn about its controls and options.

A quick summary of what you'll do:

  1. Activate the Sanas app

  2. Configure your audio settings

  3. Set up your calling app

Before you begin

Make sure you have:

  • Sanas app installed - If you don't see it on your computer, request your IT admin for installation.

  • USB Headset - Use a USB headset for the best audio quality.

  • Network login - Make sure your computer is connected to your organization's domain, and you're logged in with your user profile. This is required for auto-activation to work if your organization has enabled it.

  • Internet connection - Sanas processes audio on your device, but it needs an internet connection to verify your access.

Step 1: Activate your app

If your organization has enabled Auto-activation:

  1. Launch the Sanas app.

  2. The app logs you in automatically.

Quick troubleshooting - Ensure your computer is connected to your organization's domain, and you're logged in with your user profile before launching the Sanas app. Try relaunching to reattempt auto activation.

If this doesn't work, you can try activating via the UAK method.

If you see an activation screen:

  1. Enter your Workspace ID and User ID.

    Note: Your admin should have sent these credentials to you. If not, contact your admin.

  2. Click Activate Key.

Input fields for Workspace ID and User ID in the Sanas Accent Translator interface.

If you see a session conflict

Sanas allows only one active session per license. If Sanas is already running on another device, you'll see the message: "Existing user session identified."

Click Continue to close the other session and start a new one on this device. Make sure Sanas isn't being used on an active call before doing this.

Step 2: Configure your Sanas app

Your Sanas app version determines your app controls interface. To check your app version: click the menu (top-left corner) → About.


For app version 4.0 and above

Sanas app version 4.0 and above has two possible configurations:

If you see toggles for both Microphone and Speaker:

  1. Noise Cancellation Microphone – Keep the toggle ON to remove background noise from your speech.

  2. Microphone Input – Select your headset from the dropdown.

  3. Noise Cancellation Speaker – Keep the toggle ON to remove noise from the caller's side (what you hear).

  4. Speaker Output – Select your headset from the dropdown.

If you see only one toggle for the Microphone:

  1. Noise Cancellation Microphone – Keep ON during all calls.

  2. Microphone Input – Select your headset from the dropdown.

Step 3: Set up your calling application

Configure your softphone or video app (e.g., Zoom, Teams) to use Sanas. These settings are usually applied automatically, but verify them before each session.

In your calling app's audio settings, set:

Setting

Select

Microphone / Input

Sanas Virtual Audio or Sanas Virtual Microphone

Speaker / Output

Sanas Virtual Speaker

Select only if the Noise Cancellation for both the microphone and speaker is available, and skip selecting for the microphone-only mode (shown under Outbound Noise Cancellation).


Example (Zoom): Go to Settings → Audio, then select "Sanas Virtual Audio" as your microphone and "Sanas Virtual Speaker" as your speaker.

Make a test call

Before using Sanas on real calls, make a test call to confirm everything works. If something sounds off, double-check that the correct audio devices are selected in both Sanas and your calling app.

FAQ

What if I don't see "Sanas Virtual Audio" in my calling app?

If Sanas devices aren't showing up:

  1. Make sure the Sanas app is running and your headset is connected.

  2. Restart your calling application. The devices should appear if Sanas is running and your microphone is selected as the audio input source on the app.

  3. If still missing, contact your admin.

What if I have audio issues during a call?

Here are a few common issues caused by incorrect configuration:

  • No audio at all: Verify that your microphone is not muted in your softphone application and that the audio configuration in both the Sanas app and your softphone is correct.

  • Caller can't hear you: Ensure your connected headset's microphone is selected as the input device in the Sanas app, and that the Sanas microphone is selected in your softphone.

  • Voice break: Check your CPU usage. If it's high, close unnecessary background applications or relaunch your Sanas app session.

If the issue persists, contact your admin and report the issue.

Where do I find my Workspace ID and User ID?

Your admin sends these during onboarding. Don't share your User ID with others.

How do I know Sanas is working during a call?

Sanas runs quietly in the background. If your setup is correct, it's working. We recommend a test call to confirm.
