Make your Teams calls sound studio-quality with one setting

Teams ships with one of the best real-time noise suppression engines on the market — and most people leave it on Auto, which is fine but rarely optimal. Bumping it to High before your next big call can transform how you sound.

Where the setting lives

In Teams, click your profile picture in the top right.
Choose Settings.
Go to Devices.
Scroll to Noise suppression.

You'll see four options: Auto, High, Low, and Off.

Which mode to pick

Mode	When to use it
Auto	Default. Teams decides per-call based on your environment.
High	Cafés, open offices, kids in the next room, mechanical keyboards. Filters aggressively.
Low	Music or instruments in the background that you want others to hear.
Off	Audio recording, podcasting, accessibility scenarios where every nuance matters.

A note on hardware

If you're on an older laptop or a low-end CPU, High mode can spike your processor. You'll see Teams' helper process climb to 15-25% CPU during the call. On modern hardware (anything from the last four years) you won't notice.

Test it before the meeting

Use Teams' built-in test call: Settings → Devices → Make a test call. The bot records 10 seconds of you talking and plays it back. Try it once with noise suppression on Auto and once on High — the difference is usually obvious.

Bonus: stop your own keyboard

If you type during meetings, also enable Music mode off and check the Echo cancellation setting. Combined, these three settings make most consumer headsets sound like proper conferencing gear.
