Booster Volume

Chromebook Volume Booster

ChromeOS deliberately exposes very little audio configuration: an output slider, a device picker, and not much else. There is no equivalent of Windows Loudness Equalization and no system equalizer. That makes browser-level boosting more useful on a Chromebook than on any other platform, because it is essentially the only option available.

What ChromeOS does give you

Output device selection
Click the clock, then the arrow beside the volume slider, to choose between internal speakers, headphones and Bluetooth devices.
Per-tab muting
Right-click a tab to mute it. Useful when one tab is drowning out another, though it is on or off rather than a level.
Android app volumes
If your Chromebook runs Android apps, those follow Android's separate media stream, which can be set independently.
Linux container audio
Audio from Linux apps is routed separately again, and its level does not always track the main slider.

Boost a file in Chrome

Chrome on ChromeOS supports the full Web Audio API, including tab capture.

Frequently asked questions

Are Chrome volume booster extensions safe?

They work by applying a gain node to tab audio, which is a legitimate technique. The risk is permissions: a booster needs access to audio on the pages you use it on, and some extensions request far broader access than that. Review the permissions and the developer before installing.

Can I install an equalizer on ChromeOS?

Not at system level. Browser extensions and Android apps can process their own audio, but ChromeOS does not expose a system-wide audio processing layer.
