Question 1

What is Audio Tuner?

Accepted Answer

A free browser extension that puts per-tab controls for volume, your microphone, and your webcam in one toolbar popup. Mute and boost any tab's volume, and flip your mic or camera off, one tab at a time.

Question 2

Is Audio Tuner free?

Accepted Answer

Yes. No account, no trial, no paid tier. Every feature — volume, boost, mic, and camera — is free.

Question 3

Which browsers does it work on?

Accepted Answer

Chrome, Edge, Brave, and other Chromium browsers. A separate Firefox build is also available.

Question 4

What does boosting past 100% actually do?

Accepted Answer

It makes a tab louder than your system's maximum, using the browser's Web Audio API. Quiet dialogue becomes audible on laptop speakers. Push it too far (above ~250% on loud sources) and it may distort — boosted tabs glow amber so you can dial it back.

Question 5

How loud can a tab go?

Accepted Answer

Up to 400% — a 4× boost over the original level.

Question 6

Does it work on YouTube, Netflix, and Spotify?

Accepted Answer

Yes. Any tab that plays audio can be muted or boosted, including YouTube, Netflix, Spotify web, Twitch, and Meet. Some DRM-protected streams may limit boost; mute always works.

Question 7

Doesn't Chrome already let me mute a tab?

Accepted Answer

Chrome's built-in mute silences every tab on the same site at once. Audio Tuner mutes one tab at a time, so you can hush a single noisy YouTube tab without killing the music in the one next to it.

Question 8

What's the difference between muting a tab and the mic toggle?

Accepted Answer

Muting a tab silences what you hear coming out of it. The mic toggle is separate — it blocks that tab from capturing your microphone. Use mute for loud audio, the mic toggle when you want to stop a tab hearing you.

Question 9

How do the mic and webcam toggles work?

Accepted Answer

Each toggle turns that tab's access to your mic or camera on or off, right from the popup. Audio Tuner itself never records, stores, or transmits mic audio or camera video — it's a local on/off switch for the tab's permission.

Question 10

Can I keep the mic or camera on for one tab and off for another?

Accepted Answer

Yes. Both toggles are per tab, so your Meet camera can stay on while every other tab is blocked.

Question 11

Does it work with Google Meet, Zoom, and Teams?

Accepted Answer

Yes. Mute, boost, mic, and camera controls all work on call tabs. Some protected streams may limit volume boost, but the mic and webcam toggles apply cleanly.

Question 12

Is my data collected?

Accepted Answer

No. Audio Tuner has no servers, no analytics, and no account. Per-tab settings live only in your browser's session storage and are wiped when you close it.

Question 13

Where are my settings stored?

Accepted Answer

In the browser's session storage, locally on your device. Nothing is synced to the cloud or sent anywhere.

Question 14

Can I use it in incognito mode?

Accepted Answer

Yes, after you explicitly allow it. Open chrome://extensions, click Details on Audio Tuner, and toggle Allow in incognito.
