Speaker Cleaner

Speaker Cleaner is a fast, 100% offline utility designed to restore muffled speaker audio by dislodging trapped water droplets and fine dust using targeted sound frequency sweeps. When liquid or debris gets trapped inside your speaker mesh, audio becomes muffled, crackly, or distorted. Speaker Cleaner plays programmatically synthesized acoustic sound waves that cause speaker diaphragms to vibrate at precise frequencies, forcing out trapped moisture and dust particles. KEY FEATURES: • Water Ejection Mode: Pulsed 100–200 Hz low-frequency sweeps engineered to break liquid surface tension and eject trapped water droplets. • Dust Removal Mode: Continuous 2–8 kHz high-frequency sweeps to loosen and shake out fine dust particles. • Speaker Test Mode: Checks left, right, and combined stereo audio channel separation and balance. • Background Playback: Uses Chrome's Offscreen API so audio cleaning continues seamlessly even if you close the extension popup. • Fully Offline & Private: No tracking, no network requests, no analytics, no login, no external dependencies. • Built-in Safety: Anti-pop gain envelopes (50ms ramp-in/out), volume safety caps, and a hard 60-second auto-stop limit to protect hardware. • Accessibility & Customization: Dark/light theme support, high-contrast focus indicators, keyboard controls (Esc to stop), and screen reader announcements. HOW TO USE: 1. Open the extension popup. 2. Turn off silent mode and set your system volume to maximum. 3. Select Water Ejection, Dust Removal, or Speaker Test. 4. Point your device speakers downward and run the cleaning cycle. PRIVACY GUARANTEE: Speaker Cleaner operates entirely within your browser. It makes zero network connections and collects zero data.
