Volume & Video Master 1000% — Sound Booster & Enhancer

Boost volume to 1000% with a 12-band EQ, control speed, bass, voice and skip silence on any site.

Volume & Video Master 1000% gives you professional audio controls for any video or audio playing in your browser. FEATURES Volume Boost - Increase volume beyond the browser's 100% limit, up to 1000%. Perfect for quiet videos or laptops with weak speakers. Playback Speed - Adjust speed from 0x to 10x, shown in the popup as a percentage (100% = normal speed). Great for speeding through lectures or slowing down tutorials. Bass Boost - Enhance low frequencies for richer, fuller audio. Voice Boost - Clarify speech frequencies for podcasts, lectures, and dialogue-heavy content. Mono Audio - Mix stereo channels to mono for single-earbud listening or hearing-impaired accessibility. 12-BAND EQUALIZER Shape the sound across twelve bands, from 31 Hz to 16 kHz. Dial in your own curve, or start from a preset: Flat, Bass, Vocal, Podcast or Movie. A flat EQ is a true bypass, so it costs nothing until you use it. CLEAN BOOST Boosted audio stays clean. A built-in limiter keeps peaks from clipping when you push volume into the boosted range, so loud passages stay loud instead of distorting. SKIP SILENCE AND MORE Skip silence speeds up quiet gaps in lectures and audiobooks, so long pauses do not cost you time. It is off by default and you choose how it works: speed the gap up smoothly, or jump past it. Keep it off on music sites - and because every setting is per site, that is automatic once you set it. Even out volume smooths the difference between quiet and loud videos, and a balance slider shifts the sound left or right for single-earbud listening. KEYBOARD SHORTCUTS Shift+. and Shift+, nudge volume up and down, Shift+] and Shift+[ adjust speed, and Shift+\ resets both. No need to open the popup. SMART SETTINGS Global Mode: apply the same settings to every website. Per-Site Mode: save different settings for YouTube, Netflix, Spotify and others. Off: turn the extension off for one site and it leaves that site's own volume and speed untouched. PRIVACY Everything runs locally in your browser. The extension does not read page content, does not use analytics, and sends nothing to any server. Per-site settings are stored as a hostname-keyed map in your browser's synced storage. Permissions: storage, and tabs (to apply a new setting to the tabs of the site you just changed). No host permissions are requested. HOW IT WORKS 1. Install the extension and open any page with video or audio. 2. Click the toolbar icon. 3. Move the sliders. Changes apply live and are saved for that site.
