Tonvela - Volume Booster

Volume booster for Chrome: boost tab volume up to 400%, keep it steady, hear speech clearly. Mono, balance, hearing protection.

Tonvela is a volume booster for Chrome that makes quiet videos easy to hear. Boost tab volume up to 400%, keep loud and soft parts at a steady level, and bring speech forward. Everything runs on your device. • Up to 400% volume: drag the bar or pick 100%, 200% or 400%. A look-ahead limiter catches sudden peaks. • Listening modes: Normal, Steady, Speech, Night, Music and experimental Voice only. • Steady sound: quiet parts come up, loud parts come down. "Keep this level" turns what you hear right now into the target, with undo. • Clearer speech: Speech mode brings voices forward; Voice only runs a small speech model locally to reduce background sound. • Output device: play the tabs Tonvela processes on a chosen speaker or headset. • Mono sound and left / right balance, useful with one earbud. • Hearing protection: peaks stay under the ceiling you choose, at any level. • Back to original sound in one tap. Optional memory for each site, keyboard shortcuts, system / light / dark theme. • English, Turkish, Spanish, Portuguese (Brazil) and Arabic. Private by design: no servers, accounts, analytics or recording. Audio never leaves your computer. The microphone is only requested if you want to see output device names, and it is closed right away. How to use: open a video, click Tonvela and drag the bar. Note: 400% is 4× digital gain. Chrome pages and some protected content can't be captured.
