Instant microphone mute for macOS.

• Global hotkey: Mute mid-sentence without leaving the keyboard, configurable from anywhere.
• Menu bar click: The icon shows mute state at a glance, with a single click to toggle.
• AirPods stem-press: Works in any app, including those that ignore the system mute gesture like Google Meet in Chrome.

Squelch mutes at the macOS audio-system level, ensuring the mute gesture works in every call app and browser tab. Settings include a configurable hotkey, sound cues, and launch at login. The menu bar provides an at-a-glance mute status.

Privacy by design: Squelch has no analytics, no accounts, and no network requests. It does not open a microphone capture session, only writing the system mute flag. It is fully sandboxed.

Squelch requires macOS 14 (Sonoma) or later.
