Laptop speakers sound weak? Fix it in one click. Bass Booster adds a bass filter to the current tab — up to +15 dB of bass boost without distortion. Pick a preset or set your own level.

What Bass Booster Does

Built with precision to solve real problems without adding complexity.

0 to +15 dB Bass Boost

Adjustable low-shelf filter from neutral to +15 dB at 180 Hz for deep, punchy bass.

Three Quick Presets

Soft (+5 dB), Deep (+10 dB), and Max (+15 dB) presets for instant gratification.

Smooth Parameter Changes

Linear ramping over 120ms prevents clicks and pops when adjusting bass levels.

Dynamics Compression

Built-in compressor with -14 dB threshold and 3:1 ratio tames boosted peaks.

Badge Status

Toolbar badge shows OFF or current +NdB level so you know when it is active.

Offscreen Processing

Audio engine runs in an offscreen document for clean separation from page content.

Perfect For

Music streaming on YouTube or Spotify Web

Headphone listening that feels flat
