Sound Master geliştiren: dotanoob

Your sound, your volume.

Sound Master gives you a simple place to adjust the sound of the current website. Turn a quiet video up, soften a loud stream, or mute the whole tab in one click.

• Adjust supported audio and video from 0% to 600%.
• Choose quick presets: 50%, 100%, 200%, or 400%.
• Mute the whole tab, then return to your previous level.
• Reset to the original volume with one click.
• Switch to other playing or browser-muted tabs.
• See a clear notice when a website's own player is muted.
• Use the slider with your keyboard.

Designed to stay out of your way: warm ivory, dark ink, clear controls, and locally bundled typography. No account, ads, analytics, or audio uploads.

Firefox compatibility
Firefox 142 or newer is required. Volume adjustment works with accessible HTML audio/video players. Protected media, some cross-origin embeds, and custom Web Audio players may not support reduction or boosting. Whole-tab mute uses Firefox's built-in mute and works independently of the player. The popup explains detected limitations. Volume settings reset on navigation. Reload the page to completely detach an existing audio connection. High boosts can distort loud recordings.

Privacy
Audio is processed on your device. Sound Master reads open tab titles and addresses to display the current website and let you switch tabs; it does not upload or retain browsing history. Temporary per-tab volume and mute settings are stored only for the current browser session. It has no tracking, remote scripts, or external font requests.

The decorative waveform shows the selected volume; it is not a live audio meter.
