Auto ducking for macOS
Mac auto ducking app for voice workflows
Auto ducking is useful when you want background audio to continue, just quieter, during voice workflows on a Mac.

What is a Mac auto ducking app?
A Mac auto ducking app lowers background audio automatically when a microphone workflow starts, then restores the previous volume afterward. Auto Ducking applies that idea to macOS system output volume from a menu bar app. It watches microphone activity, lowers volume to the level you choose, and restores volume after your chosen delay when microphone use ends. It supports workflows such as dictation, calls, recordings, streaming, voice notes, and AI voice chats. The app includes fade controls, restore delay, presets, app trigger rules, output-device memory, manual ducking, and global hotkeys. Auto Ducking does not record or upload microphone audio, and it is not a full audio production suite.

What Auto Ducking is not
- Auto Ducking adjusts Mac system output volume. It is not an audio editor, recorder, compressor, noise remover, or full per-app mixer.
- Some output devices cannot be controlled by software. Auto Ducking shows an unsupported-output status when macOS does not allow volume control.
- Auto Ducking detects microphone activity so it can change volume. It does not record audio, transcribe speech, or upload microphone audio.
- Do not describe Auto Ducking as replacing professional recording tools or as guaranteeing behavior inside every third-party app.
Mac auto ducking FAQ
Does Auto Ducking record my microphone?
No. Auto Ducking does not record audio, transcribe speech, or upload microphone audio. It detects microphone activity and adjusts system output volume.
What happens when the microphone turns off?
Auto Ducking restores the previous Mac volume after your chosen restore delay, so short pauses do not cause sudden volume changes.
Can I choose how much the volume is lowered?
Yes. You can set the ducking level, fade down timing, fade restore timing, and restore delay.
Is Auto Ducking a full audio mixer?
