Micro Sniff is a small macOS utility that watches your microphone and reports when it is active. The app is free and designed to give users greater confidence about microphone use, helping protect privacy and security by alerting you to unexpected audio capture.

Core capabilities

Once installed, Micro Sniff sits in the background and watches for processes that open the microphone. When activity is detected it issues a notification and logs the event, allowing you to inspect who or what enabled the microphone and when. This continuous monitoring is intended to provide reassurance and a straightforward way to track audio input on your Mac.

Alternate option to consider

Rhinoceros (Free) is listed as a recommended substitute. It offers similar monitoring features and may present a different interface or additional configuration options if you want an alternative to Micro Sniff.
