Sound Booster Chrome extension

Sound Booster raises the volume of whatever tab you're playing audio in, past Chrome's normal ceiling, and adds bass boost and equalizer presets. It's best for quiet videos, calls, or streams that need more punch. The catch: pushing volume too high on any tab can distort or clip the audio.

What Sound Booster does

Sound Booster increases the audio volume of a single browser tab beyond the level the tab itself allows, which helps with quiet videos, calls, or music streams. It layers on a bass booster and an equalizer with presets so you can shape the sound rather than just make it louder, and it applies only to the tab you activate it on.

Sound Booster free vs paid

Sound Booster is free to install and use for boosting tab volume, bass, and equalizer presets. The listing doesn't describe a separate paid tier, so the extension's core boosting and equalizer features are available without payment.

Is Sound Booster safe?

Sound Booster needs permission to access and modify audio on the tabs where you use it, which is required for any tab-level volume booster to function. Read the permissions Chrome shows before installing, and only boost audio on tabs you trust.

Sound Booster: FAQs

Is Sound Booster free?

Yes, Sound Booster is free to install and use for boosting tab volume, bass, and equalizer adjustments.

Is Sound Booster safe to use?

It needs access to audio on the tab you use it on to boost volume, which is standard for this kind of extension. Review Chrome's permission prompt before installing.

How do I use Sound Booster?

Install it, pin it to your toolbar, open the tab with audio, then click the icon and raise the slider above 100% or apply an equalizer preset.

Why does audio distort when I boost it too much?

Pushing volume far past the tab's normal level can clip or distort the sound. Lower the boost or adjust the equalizer if audio sounds harsh.

Does Sound Booster work on YouTube and Twitch?

Yes, it works on any tab playing audio, including YouTube, Twitch, and other streaming sites.

Does Sound Booster boost system-wide volume?

No, it only boosts audio within the specific browser tab you activate it on, not your computer's overall system volume.

What are Sound Booster alternatives?

Other tab volume boosters and browser-level audio equalizer extensions offer similar per-tab volume and bass controls.

Does Sound Booster include an equalizer?

Yes, it includes a built-in equalizer with adjustable presets alongside its volume and bass boost controls.

Why isn't Sound Booster boosting a specific tab?

Reload the tab after installing the extension, since it needs to attach to the page's audio when the tab loads.

Can Sound Booster boost music streaming sites?

Yes, it works on any tab with audio, including music streaming services played through the browser.
