Ultra Volume Booster

Ultra Volume Booster gives you precise control over the audio of the browser tab you choose. Raise quiet videos, music, podcasts, streams, and other browser audio up to 600%, then shape the sound with a full 10-band equalizer. Use ready-made sound profiles for quick adjustments or switch to Custom and fine-tune every EQ band from 31 Hz to 16 kHz. Stereo balance gives you left/right control, while Smart Limiter helps control harsh peaks when using stronger boost levels. Key features: • Master volume from 0% to 600% • 10-band equalizer: 31 Hz, 62 Hz, 125 Hz, 250 Hz, 500 Hz, 1 kHz, 2 kHz, 4 kHz, 8 kHz, and 16 kHz • Flat, Bass Boost, Vocal Clarity, Movie, Gaming, and Night presets • Fully adjustable Custom EQ mode • Smart Limiter for cleaner high-gain peaks • Stereo left/right balance • Live audio level meter • Optional per-site audio profiles stored locally in Chrome • Keyboard shortcuts for volume up, volume down, and reset • Audio processing can continue after the popup closes Privacy-first design: Ultra Volume Booster processes the selected tab's audio locally in Chrome. Tab audio is not uploaded, recorded, sold, or shared. The extension contains no advertising SDK, analytics SDK, tracking pixel, account system, or remote executable code. If “Remember this site” is enabled, the site's hostname and audio profile are stored only in Chrome extension local storage on the user's device. How it works: Open a normal website tab with playing audio, click Ultra Volume Booster, enable audio processing, and adjust the controls. Chrome does not allow tab audio capture on certain internal or protected browser pages. For safety and sound quality, increase high boost levels gradually. Very high gain or extreme EQ settings can cause distortion depending on the source audio, speakers, headphones, and system volume.
