Ad-free. No data collection. Open source.

What to Expect

• It helps when a browser tab is too quiet even with browser and system volume already high.
• Control is per tab. It does not change the computer's overall volume.
• Audio processing happens locally in the browser.
• It increases gain. It does not fix poor source audio or replace hardware.

Core Features

• 0% to 600% volume range
• Per-tab audio control
• Slider for free adjustment, plus −5 / +5 buttons for precise steps
• Mute, unmute, and quick reset
• Per-domain memory
• Light and dark themes
• Extension UI in Portuguese and English
• Public landing page in EN, PT-BR, and ES

Stack and Structure

• Chrome Extension Manifest V3
• popup.* for the extension UI
• sw.js for extension orchestration
• offscreen.* for audio processing, since MV3 service workers have no Web Audio API
• constants.js shared by all three contexts
• _locales/ for localization
• tests/ covering the core flow
• No runtime dependencies: nothing from node_modules ships to users
