Why this exists
Google Meet doesn't mute when you tap your AirPods. Every other call app does. After two years of fumbling for the trackpad mid-sentence while someone politely waited, I lost patience and built my own fix.
When the AirPods stem-press happens, the mute should just happen — regardless of which app is in the foreground, which browser tab is active, or whether the call app has decided to support it.
So Squelch does the mute one layer below the call software. Tap your AirPods, and your microphone goes quiet — in Meet, in Slack huddles, in any browser tab, in anything.
And because Squelch never opens a microphone capture session, it doesn't force your AirPods into call-quality audio while it's running. (Most mute utilities do, which is why your music sounds worse the moment they're installed.) With Squelch, your music stays in full music quality until a real call actually starts.
