Stanza – No Double Voices in Teams Meetings

In the same room as colleagues? Stop hearing them twice: Stanza removes the delayed copy of their voice from your headphones.

Hybrid meeting, several laptops in one room? Then you know the problem: you hear your colleague live, and a moment later the same sentence again in your headphones. It's tiring, distracting and makes it hard to follow the conversation. Stanza fixes it. It uses your microphone as a reference for what you already hear in the room, measures the delay of the call, and removes from your headphones only the voices you have already heard live. People joining remotely never pass through your microphone, so they come through as usual. HOW IT WORKS • Turns on by itself when you join a call on Microsoft Teams for the web (teams.microsoft.com) • Continuously estimates the room-to-headphones delay and follows network changes • Fades out the delayed copy of in-room voices, while remote voices stay untouched • Adjustable maximum reduction, up to total silence, plus adjustable sensitivity • Built-in test page: try it in 30 seconds, no meeting needed • Keyboard shortcut (Alt+Shift+S), status on the toolbar icon and a Settings page • Available in English, Italian, Spanish, French, German and Portuguese (Brazil), with a language selector • Recognizes several colleagues at once, each with their own delay, so the filter keeps working when the speaker changes • A second check on the pitch of the voice: removes in-room voices more firmly and protects remote ones • “Extra precision” option: looks 0.1 s ahead to catch room voices even at the start of sentences • Microphone test page: see which of your microphones hears the room best WHAT'S NEW IN 1.1.10 • Several colleagues in the same room are now recognized at once, each with their own delay: no more gaps when the speaker changes • New “Open Teams” button in the popup • Fixed: with some Teams setups Stanza could not receive the call audio and never locked on • Steadier suppression throughout each sentence, and stronger default settings (“Extra precision” on, Sensitivity “aggressive”) • New second check based on the pitch of the voice • New microphone test page (Settings) and an icon that turns green when room voices are recognized PRIVACY All audio processing happens on your computer, in memory. Nothing is recorded, stored or sent anywhere. No analytics, no tracking. REQUIREMENTS • Teams in the browser (Chrome or Edge). The Teams desktop app is not supported, because browser extensions can only work inside the browser. • Headphones PRICING Free 7-day trial with every feature: just enter and confirm your email, no card required. After that, a paid license is required to keep the filter active. Payments are handled securely by ExtensionPay and Stripe. If the trial ends, your calls keep working normally: audio just passes through unfiltered. FREQUENTLY ASKED QUESTIONS Will it cut out people joining remotely? No. Their voices never pass through your microphone, so they are not recognized as room voices. Only when a remote person and a colleague in the room speak at exactly the same moment does the remote voice dip slightly. Why does the microphone stay on when I'm muted? Stanza needs to hear the room to recognize your colleagues' voices. That audio stays on your computer: Teams doesn't receive it while you're muted, and Stanza never records or sends it. I still hear short fragments at the start of sentences. Open the Stanza icon and move Sensitivity all the way to "aggressive". You can also turn on "Extra precision" in Settings. Others hear an echo from my microphone. Can Stanza fix that? That's a separate issue. Turn on voice isolation in Teams (Settings → Recognition → Create voice profile). Does it work in Microsoft Edge? Yes. Edge can install extensions from the Chrome Web Store. Stanza is an independent product, not affiliated with or endorsed by Microsoft. Microsoft Teams is a trademark of Microsoft Corporation.
