About this extension

**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 0.25x to 5x. 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.
## Smart Settings
- **Global Mode:** Apply the same settings to every website
- **Per-Site Mode:** Save different settings for YouTube, Netflix, Spotify, etc.
- **Disabled Mode:** Turn off the extension for specific sites
- **Persistent:** Your preferences are saved and synced across devices
## Works Everywhere
The extension automatically detects video and audio elements on any website — YouTube, Netflix, Twitch, Spotify, news sites, online courses, and more. No configuration needed.
## Privacy First
- No data collection or tracking
- No external servers — all processing happens locally in your browser
- No ads or affiliate links

## Permissions
- **All websites** — Required to access video/audio elements on all websites. Without this, the extension would only work on a limited whitelist of sites.
- **Tabs** — Required to send updated settings to all tabs from the same website when you change them.
- **Storage** — Required to save your preferences and sync them across devices.
**Note:** This extension does not read or transmit your browsing history, page content, or personal data. All processing is done locally in your browser using the Web Audio API.
