Free High Quality Sound Booster

Boost tab audio with an equalizer, speech preset, limiter, and saved site settings. Free features, local processing, no tracking.

Make quiet tabs easier to hear. Free High Quality Sound Booster gives you simple, local audio controls for the tab you choose. • Adjust volume from 0% to 600%. • Shape sound with a six-band equalizer. • Choose clear speech, music, or bass presets. • Use the optional limiter to help reduce added clipping. • Remember your preferred settings for individual websites. • Keep audio playing when the popup closes. • Stop processing for one tab or all boosted tabs. Every feature is free. No account, ads, tracking, subscriptions, or paid upgrades. Audio is processed on your device and is never recorded or uploaded. Saved site settings stay in this browser profile. On first use, read the short welcome and choose Get started. Open the toolbar button on a website, then choose Start boosting. Start with moderate volume. Processing stops when you navigate or close the tab. The limiter cannot repair distorted source audio. Some protected media cannot be captured. Capture indicators and fullscreen behavior depend on Chrome or Brave. This extension controls browser-tab audio, not other applications. The welcome includes an optional donation link. You never have to donate, and all features remain free.
