Universal approach — mute at the macOS level

macOS lets you silence any app's sound without disabling its notifications. The full visual walkthrough lives on the universal macOS method page. The short version:

  1. Open System Settings → Notifications.
  2. Scroll to Google Calendar in the application list and click it.
  3. Turn off Play sound for notifications.
  4. Google Calendar keeps showing banners and badges — just no audio.
macOS System Settings → Notifications → Google Calendar
System Settings → Notifications → Google Calendar → toggle off Play sound for notifications.

How Chirpy fills the gap

Chirpy reads the notification title and matches it against your rules. That means you can do things Google Calendar can't on its own — different sounds per channel, per person, per keyword, per server. Three quick examples:

  • Boss mentions only: a distinct chime when their name appears in any Google Calendar notification.
  • Urgent channel: a louder sound when the notification contains #urgent or #critical.
  • Silence everything else: a rule that matches all other Google Calendar notifications with no sound — banners still appear, your day stays quiet.

Want sounds that actually mean something?

Chirpy adds rule-based custom sounds on top of macOS notifications. One sound for Google Calendar mentions, another for your calendar, silence for the rest.
