Smart Mute — Automatic Audio Focus for Chrome

Background tabs talking over each other is a predictable annoyance. A news clip autoplays in one tab, a meeting recording runs in another, and your active page can barely be heard. Smart Mute solves this with a single rule: only the tab you are looking at gets to make sound.

How Smart Mute Works

When Smart Mute is active, SuperchargeAudio monitors which tab is in focus. Non-pinned background tabs — anything that is not your current active tab — are muted automatically. Your active tab plays at whatever volume you have set. Pinned tabs are exempt by default, so a pinned music or radio tab keeps playing in the background; you can turn that exception off if you want pinned tabs muted too.

Switch to a different tab and audio follows. The new tab unmutes; the previous one goes silent. There is no delay and no manual step.

Silent Mode

Smart Mute keeps one tab audible at all times. When you want complete quiet — a phone call, a meeting, a moment of focus — silent mode mutes every tab, including the active one.

Silent mode is separate from Smart Mute. You can activate it with one click and release it the same way. Tabs are not closed, players are not stopped; audio simply pauses until you turn silent mode off.

Finding the Tab That Is Making Sound

If you are not sure which tab is producing audio, the audible-tabs list in the SuperchargeAudio popup shows every tab currently playing. You can mute a specific tab directly from that list, or jump to it without hunting through your tab bar.

Smart Mute and the audible-tabs list complement each other. Smart Mute handles the automatic case — one active audio source — while the audible-tabs list covers the manual case: finding and muting something specific.

When to Use Smart Mute

• You work with many tabs open and background autoplay breaks your focus
• Video conferencing or voice calls that must not compete with other tab audio
• Music or podcast in one tab that should pause when you switch to a noisy page
• Any workflow where only the tab you are actively using should be heard

Per-Site Audio Settings

SuperchargeAudio remembers your preferences per website. If you have set a specific volume or audio profile for a site, those settings persist when that tab becomes active. Smart Mute controls which tabs can play; per-site audio controls how they sound when they do.

Privacy

Smart Mute runs entirely on your device. No tab data, audio content, or browsing activity is transmitted anywhere. SuperchargeAudio has no telemetry, no account system, and no remote configuration.
