Something not working?

1. Reload the tab (⌘R on Mac, Ctrl+R on Windows).
2. Start the video or music again.
3. Open Volume Booster and turn the knob once more.

If it still stays silent, press Reset in the popup, then turn the knob again.

Chrome doesn’t let extensions capture sound on its own pages, such as Settings, New Tab, the Extensions page or the Chrome Web Store. Any normal website works.

Check that the Limiter key in the popup has its orange light on. The limiter stops crackle at high levels. If the source itself is already distorted, a lower level or the Voice mode usually sounds cleaner.

Volume Booster boosts one tab at a time for now. Turning the knob on a new tab moves the boost there, and the popup tells you when that will happen.

Fullscreen works while a tab is boosted: the whole window goes fullscreen. Press Esc to leave it as usual. If a site misbehaves, press Reset, enter fullscreen, then boost again.

• Voice brings speech forward: films with mumbled dialogue, quiet people on calls, lectures.
• Bass adds low end for small laptop speakers.
• Night makes quiet parts louder and loud parts softer, so you don’t have to keep changing the volume.

It’s the boost level of that tab: 250 means 250%. No number means the tab plays at its normal level.

Press Reset, or turn the knob back to 100 with the Normal mode selected. The tab goes back to its normal sound right away.
