Whisper Mode: the one-keypress way to keep your Mac quiet

You're at the café. The barista calls your name. You miss it because Spotify is twelve clicks deep on your second monitor and your laptop volume keys would cut the call you're half-listening to. The master volume slider is too blunt: take it down and you can't hear the call either.

What Whisper Mode does

Whisper Mode is a single keystroke (default ⌘⇧W) that does two things at once:

• Caps every non-call app at 5–10% — music, Slack pings, browser tabs, notifications all drop to a polite background level.
• Leaves call apps (Zoom, Meet, FaceTime, Discord, Slack huddles) untouched so the voice you're listening to stays at full volume.

Tap the hotkey again to release. Your prior levels come back exactly.

Why a hotkey matters

Volume management is one of those things you only do reactively. The barista calls; you can't fish for a menu bar slider. Whisper Mode is built around "oh no, oh — handled" — a single, predictable keystroke that always does the same thing and is always reversible.

Customizing the threshold

The default cap is 8%. You can change it per profile:

• Library: 3% — even softer.
• Café: 8% — default.
• Open office: 15% — quiet but not silent.
• Late night: 5% — soft enough that a sleeping partner won't hear it.

You can also override which apps count as "call apps." By default we include Zoom, Meet, FaceTime, Discord, Slack, Microsoft Teams, and Webex. If you use a more obscure call app, add it to the call-apps list and Whisper Mode will preserve its volume too.

When not to use it

Whisper Mode is global. If you only want to mute Slack pings, just turn Slack down individually — don't sledgehammer everything. The mode is for environments where every stray sound is a problem.
