Microsoft Teams AI background noise suppression now rolling out

This feature will automatically remove unwelcome background noise during your call or meetings. AI-based noise suppression works by analyzing an individual’s audio feed and using specially trained deep neural networks to filter out the noise and retain only the speech signal.


As you get it (feature rollouts take some time, rollout expected to complete in mid-December), you will find it under device settings:


• Auto (default) The Teams app decides on the best level of noise suppression based on local noise.

• Low  Suppresses low levels of persistent background noise, such as a computer fan or air conditioner. Use this setting for playing music.

• High  Suppresses all background sound that isn’t speech.


  • For this option, your computer’s processor must support Advanced Vector Extensions 2 (AVX2).
  • Enabling this option uses more computer resources.

• Off Noise suppression is disabled. Use this setting for high-fidelity microphones in low noise environments.

You can change this setting at any time. Once changed, the setting carries over to your next meeting or call.

The warning about processing and the fact that it is Windows Desktop only suggests this is all being done client-side.
